Propuesta de rehabilitación del pavimento de la vía Salasaka centro km 0+000 hasta Huasalata km 4+000 del cantón Pelileo provincia de Tungurahua

Abstract

For the elaboration of this technical project began with the manual vehicle counting of the road from Salasaka center Km 0+ 000 to Huasalata Km 4 + 000 for seven days, to determine the (TPDA) was classified as a class II Collector Road And the current (TPDA) is equal to 904 Vehicles / day and its projection in 15 years is equal to 1432 Vehicles / day. To continue with the field work, the road was abscissed with the help of a Garmin etrex 20 GPS, every twenty meters. To determine the Pavement Condition Index, information was collected on the failures of 16 sampling units, through a methodology, the PCI of 74.18 was calculated and it is classified as very good, so road maintenance must be carried out. With the road already abscised, an inventory of what exists was carried out such as: water passages, wells, entrance to other villages, gutters, sidewalks, length and width of the road, then the test was carried out with the Benkelman Beam in 21 stations, according to The deflections determined the current state of the road, it is shown that both the subgrade and the pavement have a good behavior. To carry out the soil tests, four open pits were carried out and eight samples of material were extracted, according to the granulometry it has a good distribution of pebbles, gravel and clayey sand, the percentage of (CBR) resulting of good for subbase and poor - fair for subgrad.
