Diseño geométrico vial y del pavimento de la vía Salcedo - Alpamalag en los sectores San Andrés de Pilaló - San Pedro de Jachaguango desde la abscisa 0+000 hasta la abscisa 4+500 perteneciente al cantón Salcedo, provincia de Cotopaxi

Abstract

The geometric design of the Salcedo – Alpamalag road was carried out due to various problems such as the difficulty of transportation for farmers in the sector, poor condition of the road and its lack of maintenance, resulting in low economic production in the adjacent sectors. The technical project began with a prior inspection of the place, in order to collect information and carry out the topographic survey with high precision equipment (RTK), subsequently a vehicle count was carried out for 7 days for 12 hours a day to obtain traffic levels and then its TPDA, then 6 soil samples were extracted at different points of the road, which were taken to the faculty laboratories for their respective tests of moisture content, granulometry, Atterberg limits, Proctor compaction and CBR, with the help From the CBR data of the soil, it was possible to design the structure of the pavement and the thicknesses corresponding to each of its layers, complying with the AASHTO 93 regulations and finally the reference budget was calculated based on the volumes of work, materials and equipment necessary to the correct execution of the project. With the analyzes carried out, a mountainous relief was determined, in addition to the fact that it is a Class IV road, the tests determined that the soil is a silty sand (A-2) and the design CBR for the pavement is 8%, having a The result was a 5 centimeter asphalt layer, a 15 centimeter granular base and a 20 centimeter subbase.
