    Evaluación del proceso de conservación de la estructura del pavimento asfaltico de 4,2 km de la vía Cunchibamba - San Andrés
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-08) Aguilar Salazar, David Salomón; Aldás Sánchez, Milton Rodrigo
    An analysis of the current situation of the Vía Cunchibamba – San Andrés was carried out due to its intense commercial and tourist activity, which has caused a notable deterioration in its surface. Given this circumstance, it will be deemed necessary to examine the deficiencies and condition of the road, identifying the most worn areas and critical problems, in order to propose a maintenance plan that guarantees safe and comfortable circulation. A research process was initiated to carry out a georeferenced topographic survey, collecting 550 points. Then, a vehicle count was carried out for 12 continuous hours over 7 consecutive days, determining the projected TPDA and TPDAf for 20 years, considering the road as a Class II Collector. Next, the soil was studied using granulometry tests and Atterberg limits, making pits of one cubic meter for each kilometer and in the initial Abscissa, the California Support test, obtaining an average of 20.43 percent, classifying it as a subgrade quality from Fair to Good and Excellent. In addition, a deflection analysis was carried out in the rolling layer using the Benkelman Beam, showing type I deflections. Finally, the Pavement Condition Index method was used, identifying existing faults on the road to carry out the respective maintenance plan and a reference budget for conservation so that the road can be in an optimal state for its use.
