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 La Libertad – Nitón road allows moving from the Pelileo canton to other hamlets as well as to the Ambato canton, providing connectivity and economic development of the place, for which reason, a process of conservation and maintenance of the road has been designed in order to improve its level of service and guarantee the durability of the road infrastructure. A topographic survey was developed with RTK technology, obtaining a digital road model with an average road width of 6.00 m that has two lanes of vehicular circulation and side ditches for drainage. In addition, a manual vehicular capacity was carried out for 7 consecutive days of 12 hours a day thus determining an Annual Daily Average Traffic (ADT) of 1000 veh/day with a projection for 20 years (2045) of 1080 veh/day that according to the MTOP is classified in a “Collector Type II” road. On the other hand, the current condition of the pavement was evaluated according to the Pavement Condition Index (PCI) method where 14 sampling units were analyzed obtaining a PCI value equal to 85.74 which indicates that it has a “Good” condition although it requires maintenance to avoid progressive deterioration. In addition, laboratory tests were carried out on three soil samples taken along the track every 1000 m; the results gave us that the soil corresponds to a poorly graded silty sand (AASHTO A-2-4- / SUCS SM) with a plasticity index of less than 3.5 and an average CBR of 26.03%, classifying it, as well as an excellent subgrade. Finally, a technical proposal for conservation and maintenance was designed that includes solutions such as surface sealing, crack sealing, surface patch and deep patching with their respective specifications based on the AASHTO and MTOP standards, thus guaranteeing that the proposed plan will contribute to reducing costs in rehabilitation and improving road safety through a more efficient transport system.

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.

On the road located in sector El Lindero belonging to Yatzaputzán, Pilahuín parish, Ambato canton, which corresponds to sections one, two, and three, given the unfavorable conditions that currently do not guarantee safe traffic for the population, an assessment was carried out to optimize its functionality and extend its useful life. As a starting point, a georeferenced topographic survey was carried out using RTK, recording 1500 points along 5,544 km, processed in Civil 3D. The average annual traffic (TPDA) was determined by a manual count carried out over seven days, in twelve-hour shifts, classifying the road within the Class III Collector category. Based on soil samples extracted in the field, granulometry, Atterberg limits, compaction, and CBR tests were carried out, identifying two types of soil: gravel and silty and clayey sands. The CBR values indicated a bearing capacity ranging from fair to poor. On the other hand, the surface evaluation using PCI considered 20 sampling units, of which 5 presented critical conditions. The score obtained, 54.90, placed the pavement in the Regular category, evidencing the need for intervention. The Benkelman Beam deflection test, carried out at 23 stations specified every 250 meters, reported a Type III deflection, rating the behavior of the subgrade as Good, but the behavior of the pavement as Poor. The results justify the implementation of rehabilitation measures and road safety improvements to promote mobility and user well-being. To this end, a Unit Price Analysis (APUS) proposal and a reference budget are proposed to guide road maintenance and improvement activities.

The geometric and structural pavement design was developed for the road connecting the Viejo Minero sector with the Pondoa parish, which belongs to the Baños de Agua Santa canton in the Tungurahua province. This intervention covers a total length of 7.219 kilometers and addresses the need for rehabilitation. The importance of this road lies in its role as a vital artery for local residents, who rely on it for the transportation of agricultural and livestock products. Furthermore, its route plays a key role as an alternative connection to areas renowned for their scenic beauty and tourism value. During the diagnostic phase, a traffic study was conducted that identified an Average Annual Daily Traffic (AADT) of 31 vehicles, predominantly composed of light transport vehicles, machinery used in agricultural activities, and light-duty trucks. Based on this information and in accordance with the guidelines established by Ecuador’s Ministry of Transport and Public Works (MTOP), it was determined that the road corresponds to a Class IV classification, which refers to rural roads intended to support low traffic volumes. This classification served as the basis for defining the design parameters necessary to ensure functionality and operational safety. Regarding the geometric design, the project included both horizontal and vertical alignments, cross-sections adapted to the environment, as well as specific road safety criteria. All of these elements were tailored to the topographic and geotechnical characteristics of the study area, following a detailed topographic survey and soil analysis. The results revealed sections with low load-bearing capacity soils, which became a determining factor in the structural configuration of the pavement and the selection of appropriate construction materials. The pavement structure was designed using the 1993 AASHTO method, suitably adapted to the local conditions in terms of traffic, climate, and soil type. Based on these parameters, a flexible pavement solution was selected, designed to provide efficient performance

This technical project focuses on making a proposal for the geometric design of the road that connects the sectors called Salcahe Tiobamba, Salache grande and the PanAmerican Highway E35. The justification for this intervention lies in the absolute need for an optimal road infrastructure, designed and executed in accordance with current technical regulations, which is a critical factor for sustained socioeconomic development and operational safety. To this end, an on-site visit to the project was made in order to carry out the topographic survey with high-precision GNSS RTK equipment, a vehicle count called TPDA, and also to excavate soil samples to determine the properties in the laboratory. The geometric design of the road was also carried out following the current MTOP and NEVI 12 regulations, which give us the technical parameters of the horizontal and vertical alignment and cross-sections. Upon analyzing the results, it was possible to determine the Type III road, undulating relief and the prevailing soil along sections 1 and 2 is a silty sandy soil, whose subgrade varies between regular, good and excellent, which are favorable aspects for road design and construction. The pavement structure consists of a 20 cm subbase, a 15 cm base and a 5 cm asphalt layer. Finally, a reference budget of $412,795.24 was calculated based on a breakdown of all the activities to be carried out during the construction of the project

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.

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.

The road infrastructure of a city is essential for its economic and social development. In this context, studies were conducted that revealed the deterioration of the roads in the analyzed sector, compromising the safety and reliability of users. The analysis began with the determination of the Pavement Condition Index (PCI) for the roads in zone 31. Subsequently, the current and projected Average Annual Daily Traffic (AADT) was evaluated, complemented by tests such as natural moisture content, granulometry, Atterberg limits, Modified Proctor compaction, and California Bearing Ratio (CBR). Based on these results, a maintenance plan was proposed according to the identified damages. The study projected traffic over a 20-year period for the roads requiring intervention, including Ciro Peñaherrera Street, Pedro Vásconez Avenue, and Julio Castillo Street, with traffic volumes of 747, 2049, and 1166 vehicles, respectively. According to the MTOP 2003 classification, these roads are categorized as collector roads, which will help improve mobility in the surrounding areas. Soil tests indicated that the subgrade consists of high-quality clayey sand, providing a suitable base for road rehabilitation. Finally, the estimated cost to implement the maintenance plan amounts to 801,980 US dollars and 51 cents, which will enhance traffic conditions and extend the lifespan of the road infrastructure.

Given the transportation difficulties faced by the residents of the San Andrés parish, this project proposes to substantially improve the road infrastructure in this area. By optimizing the road that connects the Yanayacu bridge with Píllaro between sections 0+000 and 4+875, productive and tourist activities will be facilitated, generating new development opportunities for the Tungurahua sector. The project was structured into three main phases. The first phase corresponded to the preliminary studies, which included fieldwork such as topographic surveys and vehicle counts to determine the ADT of the road. Subsequently, in the second phase, soil studies were conducted, including destructive and non-destructive tests, to characterize the physical and mechanical properties of the soil, as well as the pavement deflections. Finally, in the third phase, using the data obtained in the previous phases, the geometry of the road was redesigned, taking into account the newly calculated TPDA, the soil characteristics, and the applicable technical standards. In this phase, the horizontal, vertical, and transverse design was defined, as well as the other geometric elements. Additionally, a budget was prepared that includes all the costs associated with the construction of the new road, thus ensuring the project's viability. The topographic analysis revealed a mountainous terrain with steep slopes, while the traffic study classified the road as class I. The soil tests indicated a sandy loam material with a CBR of 19.18 percent suitable for subgrade. The results of the deflection measurements with the Benkelman beam showed that 89 percent of the evaluated track length needs reconstruction. Based on these results, the pavement structure was redesigned, consisting of a 7.5 cm asphalt layer, a 15 cm base, and a 20 cm subbase. Finally, the estimated budget calculated for this project was $1´686,962.16
