This paper develops a road maintenance plan for the section between Redondel La Patateñita and El Mirador, in the canton of Patate, province of Tungurahua, with the aim of assessing the current condition of the pavement and proposing a technical alternative that guarantees its functionality and durability. The research was structured using a quantitative approach, combining field and laboratory procedures, in accordance with the guidelines of ASTM D6433 and the AASHTO-93 methodology. In the diagnostic phase, a topographic survey was carried out using RTK technology and a drone, complemented by a vehicle traffic study, which yielded an Average Annual Daily Traffic (AADT) of 1,768 vehicles/day. Using the Pavement Condition Index (PCI) method, the results showed values ranging from 29 to 84, placing the pavement in “Fair” to “Very Good” condition, with an average of 63.14, corresponding to a “Good” condition. Laboratory tests on grain size distribution, Atterberg limits, modified Proctor, and CBR determined that the soil is silty sand (SM) with low plasticity and an average CBR of 10%, classifying the subgrade as having “Fair to Good” bearing capacity. These results served as the basis for the structural design of the flexible pavement, whose proposed package consists of a 5 cm asphalt layer, a 20 cm granular base, and a 20 cm subbase, reaching a total thickness of 45 cm. Periodic maintenance and selective rehabilitation of critical sections are actions to preserve the pavement's lifespan and optimize the use of available economic resources. The reference budget of $700,725.00 includes the costs of materials, labor, and equipment, based on updated prices from the Chamber of the Construction Industry (CAMICON) magazine.

The main objective of this project was to assess the condition of the urban road infrastructure in the Santa Rosa parish, located in the Ambato canton, specifically in zone 53–56. To achieve this, the Pavement Condition Index (PCI) was used, allowing for the identification and classification of roadway failures, as well as the determination of their severity levels. Additionally, a georeferenced survey of the area was carried out using precision equipment such as an RTK, GPS and a drone, which facilitated the acquisition of accurate coordinates and the capture of images for a detailed visual analysis of the existing defects. In the second phase, a traffic study and an analysis of its impact on the road infrastructure were conducted, along with a soil study to evaluate the quality of the material beneath the roadways. This phase made it possible to determine the type of maintenance required based on the road conditions and the results obtained from the PCI, as well as to calculate the Average Annual Daily Traffic (TPDA) and its future projection. The outcome of this work was the development of an intervention plan for road maintenance, which mainly includes the type of intervention required according to the PCI index, as well as an estimated budget covering the costs of the activities necessary for roadway rehabilitation and preservation. This budget analysis will serve as a tool for local authorities to make informed decisions and optimize resources to maintain and improve the road network, all with the aim of enhancing mobility and the quality of life of the residents of the Santa Rosa parish.

The road network is a system of roads that facilitates the movement of people and goods. However, there are areas where the road network is in extremely poor condition due to neglect by the relevant authorities. This results in many sectors lacking adequate road infrastructure due to the deterioration of the road surface, which primarily affects the functionality of the roads. Therefore, evaluating the road network in areas such as the Totoras parish, Zone 61, is important to define the areas requiring intervention. This evaluation provides relevant information that will allow for determining the appropriate type of maintenance, based on the severity of the road surface deterioration, thus extending the useful life of the evaluated roads. To this end, three phases of action were established, planned according to the specific objectives to be developed. These phases included activities such as topographic surveying using drones and RTK (Real-Time Kinematic) technology. In addition, a traffic study was conducted using manual vehicle count data and the 30th-hour design time method for calculations. Five laboratory tests were also performed: natural moisture content, particle size analysis, Atterberg limits (liquid and plastic limits), modified Proctor compaction test, and CBR test. Furthermore, the pavement condition was evaluated using the PCI method and complemented with the pavement structure design, ultimately leading to the development of a preliminary budget for the project. The road network assessment was carried out on a total of 11 roads, 8 of which are fully paved and 3 of which have a mixed composition of asphalt and paving stones. A total of 352 defects were identified, 8 of which were sidewalk defects and 3 curb defects. Likewise, the results revealed that patching and service connection failures are predominant in the sector, occurring 130 times, while bulging and subsidence failures, as well as lane/shoulder unevenness, were observed once along the evaluated area.

In Ecuador, there are sectors whose road network is in poor condition due to neglected road maintenance processes. This leads to the deterioration and wear of the existing road network, primarily affecting its functionality, which is closely linked to the social and economic growth and development of a sector. Therefore, the evaluation of the urban road network in sectors such as the Izamba parish, located in Zone 30, is important for identifying areas that require some type of intervention through the application of preventive maintenance techniques that prevent the loss of the road structure and the additional costs associated with poor transportation and vehicle operation. To this end, activities such as topographic surveys using equipment such as drones and RTKs were carried out, in addition to vehicle traffic studies using the thirtieth-hour method, which employs manual vehicle counting. This was also complemented by a soil study, which included tests such as natural moisture content, particle size analysis, Atterberg limits, modified Proctor (method B), and CBR, primarily seeking to establish the properties and characteristics of the sample tested. In addition, the road network was evaluated using the PCI (Pavement Condition Index) method to assess the current condition of the road network and identify appropriate maintenance techniques based on the determined PCI value. Finally, the pavement design was developed based on the AASHTO-93 standard, and the reference budget was prepared. The road network evaluation was carried out on a total of eight roads, of which four are fully paved, three have paved and cobblestone sections, and one is entirely cobblestone. The results revealed 247 failures in both roads and sidewalks, of which 9 correspond to existing damage to the sidewalks and 5 are located in cobblestone streets. Furthermore, it was identified that patching and service connection failures occur most frequently, with corrugation and parabolic or sliding cracks being the least common failures.

Currently, the condition of the roadway that covers the entire parish of San Bartolomé de Pinllo is significantly affected. This situation is attributed to the numerous pavement failures, mainly due to the constant presence of heavy traffic, as well as the lack of care and absence of maintenance. In Ecuador, this problem arises frequently in various areas, which drives the need to formulate proposals to address these deficiencies. The main focus of this project was the collection of concrete information regarding the condition of the roads, curbs, and sidewalks in the parish of San Bartolomé de Pinllo, specifically in zone #45, located in the city of Ambato. The goal was to ensure efficient road safety and to improve transportation and secure connectivity. In the initial stage, referred to as the first phase, information was gathered to create a database reflecting the current condition of the roadway elements, such as sidewalks and curbs, with their respective types of damage identified through a visual inspection within the study area. This served as the foundation to begin technical study known as the Pavement Condition Index (PCI). In the second phase, the PCI study enabled the classification of each type of failure, including its severity level, alongside an assessment of the surface layer quality. Data collection was carried out using a georeferenced survey with an RTK system. As a result, a referential budget was developed to outline the estimated costs required for the maintenance of the roadway in zone #45 of the San Bartolomé de Pinllo parish. This information will be submitted to the Municipality of Ambato and is intended to serve as a contribution to the community in collaboration with the Technical University of Ambato.

A road infrastructure in optimal condition is essential to ensure connectivity, safe mobility, and community development. In this context, and considering the needs of the Quisapincha parish, this project aims to develop a road maintenance plan for the road connecting the Turuloma and Galpón neighborhoods, as its condition shows considerable deterioration that affects traffic, road safety, and the socioeconomic development of the area. In addition, structural failures such as cracks and potholes increase risks for users and limit traffic flow. The development of an efficient road maintenance plan began with a comprehensive assessment of the current condition of the road. This phase included a topographic survey using RTK equipment, soil analysis to establish its physical and mechanical properties, and a traffic study. To complement this information, the Pavement Condition Index (PCI) was applied, which allowed for an objective measurement of the degree of deterioration of the road. With the information gathered, an optimal structural design for flexible pavements was developed and a reference budget was formulated, ensuring efficient and sustainable road construction. After a thorough analysis, it was determined that over the next 20 years, the road evaluated will support an average traffic volume of 1,856 (one thousand eight hundred and fifty-six) vehicles per day. Based on these conditions, the road was classified as Class II, and it was noted that the 4.4 km road is fully paved; however, there were a total of forty-nine faults. Likewise, an average CBR index value of 11.38% was determined through soil studies, classifying the subgrade as between fair and good for structural use. Based on this data, a flexible pavement with a total thickness of 45 cm was designed, distributed in 5 cm of asphalt pavement, 20 cm of granular base, and 20 cm of subbase. Finally, the reference budget yielded a total project cost of $575,467.53 (five hundred seventy-five thousand four hundred sixty-seven dollars and fiftythree cents) after a comprehensive technical study.

The road connecting the Patateñita roundabout and the Mirador viewpoint in the Patate canton is in a state of significant deterioration, affecting its functionality and safety. This situation is due to increased vehicle traffic and the lack of adequate periodic maintenance, which has led to structural and surface failures in the pavement. In view of this problem, this project proposes a road maintenance plan that will allow the road to be rehabilitated efficiently, ensuring better mobility and safety conditions for users. The project began with a high-precision topographic survey using RTK equipment to obtain a detailed representation of the terrain. Subsequently, a continuous vehicle count was carried out over seven days, which allowed for the projection of a future AADT of 3,904 vehicles per day over 20 years. With this information, the Pavement Condition Index (PCI) method was applied, identifying a total of 38 failures, predominantly longitudinal and transverse cracks. Next, laboratory soil studies were carried out in accordance with SUCS and AASHTO classifications, determining a subgrade of type A-2-4 (silty sand) with an average CBR of 10.1%, suitable for structural design. Based on these results, a flexible pavement was designed according to the AASHTO 93 methodology, consisting of 5 cm of asphalt pavement, 20 cm of granular base, and 20 cm of subbase, reaching a structural package of 45 cm. Finally, a reference budget estimated at $700,725.00 was prepared, which supports the economic viability of the project and guarantees the execution of an intervention in accordance with the technical standards established by current regulations.

This study aims to develop a road maintenance plan for the section between Shell and Madre Tierra, with a total length of 5.3 km, located in the Mera canton, province of Pastaza. The proposal addresses the need to improve road infrastructure conditions, based on the results of the Pavement Condition Index (PCI), which yielded an average score of 49.80, classifying the road as being in “fair” condition and requiring rehabilitation. The methodology applied was technical-descriptive and structured in several stages, including topographic surveys using GNSS RTK equipment, traffic studies with manual counting stations, soil sampling for laboratory analysis, and visual distress assessment using the PCI method. In addition, the flexible pavement structural design was developed following the AASHTO 93 guidelines, incorporating parameters such as CBR, resilient modulus, design reliability, standard deviation, and equivalent single axle loads (ESALs). The resulting pavement structure consisted of a total thickness of 75 cm, distributed into a 40 cm subbase (class 2), 20 cm granular base (class 2), and a 15 cm hot mix asphalt wearing course. Based on the updated unit price analysis, considering equipment, materials, labor, and current MTOP regulations. The total estimated cost for the project is $1,587,554.72, covering tasks such as staking, pavement removal, structural layer placement, and horizontal signage. Water spraying for dust control was excluded from the budget, as the area presents high rainfall and minimal earthwork, making additional dust mitigation unnecessary. As a result, this project proposes a comprehensive and technically feasible solution to rehabilitate the road effectively, improving connectivity between rural communities and promoting economic development by ensuring safer and more efficient access routes.

The purpose of this project is to evaluate the road infrastructure at the request of the GAD, with the aim of obtaining detailed data and information on the current condition of the various roads in Zone 26 of the Izamba parish in the Ambato canton, and to determine the necessary interventions for each road. A detailed database was created for the GAD Ambato based on the various failures observed in flexible pavement, which were obtained through a field inspection and recorded using the UTM Geo Map and Timestamp Camera applications on a phone. This facilitated the implementation of road maintenance works according to the interventions and recommendations suggested by the road evaluation. The process was carried out in three phases, with the following activities: Phase One: Topographic survey of the area using RTK equipment in conjunction with a drone. The data was then processed using specialized software to create a detailed map of the area, which included the roads, sidewalks, curbs, drainage systems, and even the irrigation channels present. Phase Two: The evaluation of the road infrastructure was performed using the Pavement Condition Index (PCI), which allowed for the classification and determination of the severity of the observed failures based on sampling units. This allowed the identification of the necessary works to restore the functionality of the roads, ensuring proper and comfortable vehicle mobility for the area’s residents. These failures were recorded using the aforementioned applications, and all data was georeferenced. As a result, complementary studies were carried out, including the Annual Average Daily Traffic (TPDA), soil study, and CBR testing. This data was then used to develop the design for the road infrastructure, with suggested thicknesses for its implementation according to AASHTO 93, MTOP, and NEVI standards. Phase Three: After completing the road evaluation, a reference budget was prepared based on the recommendations for the works and interventions needed for road maintenance and rehabilitation in Zone 26 of the Izamba parish in the Ambato canton.

He main objetivé of this research has to evaluate the rad network in the urban area of the Izamba parish, part of the Nueva Historia of Ambato, located in zone 28 of Tungurahua province. This study arose due to the importance of road infrastructure for socioeconomic development and the recurring issues of deterioration caused by vehicular traffic, weather conditions, material quality, and lack of road maintenance. Using the Pavement Condition Index (PCI), the existing failures in both flexible and interlocking pavements were analyzed, allowing the determination of the type of intervention required for each road to ensure its functionality and preservation. To achieve the objectives, a quantitative methodology was adopted, developed in three phases. First, a topographic survey was conducted using a drone and an RTK device, which enabled the acquisition of high-resolution images and the development of the area's planimetry. Subsequently, 144 failures were identified and classified across 16 roads, covering 4959.5 meters of flexible pavement and 470.1 meters of interlocking pavement, with a total length of 5429.6 meters. Additionally, a soil study determined a CBR value of 20.36 percent, classifying the subgrade as excellent. The study also defined the type of road maintenance required for the flexible pavement roads: rehabilitation for one road, periodic maintenance for four roads, and routine maintenance for six roads. Finally, a referential budget was prepared. The results provided a database for the GAD Municipality of Ambato to support decisionmaking regarding the conservation and maintenance of the road network in the urban area of Izamba parish. This study emphasizes the importance of a comprehensive technical assessment to ensure the sustainability and functionality of urban road infrastructure, contributing to the development of the parish.
