Comparison of studies through laboratory tests to loan material (ballast) of San Jose and AGRE SA quarries treated with asphalt emulsion or cement

Abstract:

Currently there are many road problems and one of the causes of this is the inadequate material that we use on site, that is why this research is born, to find through laboratory test studies and information sources a material that can provide the Engineers the guidelines and appropriate technical criteria to efficiently design the layers of unpaved and paved roads or roads, providing them with structural stability to achieve their best possible performance in terms of technical-economic efficiency for the benefit of society as a whole [1]. The engineering of pavements has been carried out for several years, existing regulations that must be complied with in its construction, in addition to books that have been published for the teaching of the subject as basic texts [2] to specialized information in the field of road pavements. finds very dispersed, but also not at all sites pavement behavior is the same so there is a need to continue research on the subject. In Portoviejo, province of Manabí, a study was made of different quarries to extract material for the construction of roads, the objective of this work is to characterize the clays of the quarries of Megarok and San José and compare them with material mixed with asphalt to determine the characteristics of these for the construction of resistant roads [2]. Other investigations have been developed with the objective of evaluating the quality of clays for pavements and other types of construction [4], in this investigation different tests were performed in the laboratory with natural soil introducing different percentages of lime, with the results verified, that with 6% of lime is adequate since they reach low levels of …
