Plan de conservación para la estructura del pavimento de la vía Aláquez – Mulaló en el tramo de la abscisa 0+000 hasta 4+970 de la provincia de Cotopaxi

Abstract

The objective of this technical work is to carry out a conservation plan for the pavement structure of the Aláquez-Mulaló road in the section of abscissa 0 + 000 to 4 + 970 in the province of Cotopaxi, since the roads in the province of Cotopaxi do not have a road maintenance plan for which they were designed. Initially, a topographic survey and road inventory were carried out, where the characteristics of the road, length, width, as well as the presence of sidewalks, ditches, sewer wells and adjacent streets were verified. A traffic study was carried out where the Average Annual Daily Traffic (TPDA) was determined to be 2002 vehicles / day, therefore, it is classified on a class II collection road, which will suffice with the two current lanes, one in each address, in addition to uniting two important parishes such as Aláquez and Joseguango Bajo. To assess the current state of the pavement structure, the Pavement Condition Index (PCI) was used, which identifies the amount and severity of surface faults found in the tread layer, it was determined that the average PCI is 74.6 percentage, classifying on a road in very good condition, that is, on the Aláquez-Mulaló road, it indicates that it needs road maintenance. Subsequently, a samples was carried out every kilometer in order to extract soil samples and carry out laboratory soil tests such as granulometry, Atterberg limits, compaction and the California Support Index (CBR) test. Finally, according to the results obtained in the PCI test, routine maintenance must be carried out in order to extend the design life of the asphalt binder. Said routine maintenance has a reference budget of 32,304.07 USD.
