    Propuesta para la rehabilitación de la red vial de Tungurahua, grupo 1 de la vía Manzana de Oro-Cevallos de la provincia de Tungurahua

    The Manzana de Oro road presents a very advanced deterioration, since being poorly designed it generates inconveniences in the mobilization between cantons, which influences Ambato and Cevallos, however, this does not apply only for maintenance since its failures are of great magnitude and are prone to generate accidents, so it is necessary a redesign and improvement of this infrastructure that is beneficial not only for the economy of these sectors but to provide security to the people. To conduct the new design of this road, a topographic study was carried out to identify the conditions in which it is located, based on points that were placed at an established distance. During consecutive hours near the starting point, it was possible to calculate the TPDA planned for 20 years and to conclude that the road belongs to Class R-I according to M.T.O.P. In addition to this, the physical and mechanical properties of the extracted soil were analyzed through soil tests guided under the AASHTO standard, such as moisture content, granulometry, Atterberg limits, modified Proctor and the CBR study which in turn generated results in a range between 11 to 20 percent qualifying the sample as a regular-good soil for pavement design. Finally, a new geometric design of the road was proposed based on the results that allowed unit price analysis and estimation of a reference budget.
