Combinación granulométrica por fracciones de áridos para el diseño de una mezcla asfáltica elaborado bajo el método de bruce Marshall

Abstract

The conservation of the flexible pavement is largely determined by the granulometry, hence the importance of the selection of the aggregates so that it does not deteriorate before its useful life and avoid problems of rutting, cracking and aging of the flexible pavement. Analyzing the results of the quality control report carried out by GADPEO, it is determined that the granulometric combination established under the Marshall method shows that the aggregate fractions are complying with minimum design ratios, which are within design specifications for roads and bridges made by the Ministry of Transport and Public Works of Ecuador MTOP, 2002, this also leads to constant monitoring of tests in laboratories specialized in pavements for the different quarries that supply aggregates and stone with the purpose of establishing suitable materials in the asphalt mixtures.
