Diseño de adoquines con mezclas asfálticas en caliente utilizando agregados reciclados y no reciclados

Abstract

To make pavers with hot asphalt mixtures with recycled aggregates, samples of aggregates from Dr. Julio Enrique Paredes Street were taken, which were obtained through a milling process, and then a cracking process was carried out to perform the tests. The percentage of residual asphalt of the recycled aggregates was determined by the asphalt extraction test in which a percentage of 5.8% of asphalt cement was determined, then a granulometric analysis was performed to determine the particle size, reaching a particle size. Maximum size of half an inch. In order to make the cobblestones with unrecycled aggregates, crushed aggregates of the Los Pinos Mine were acquired, and it was carried out with a granulometry of maximum size of half an inch. The Marshall test was carried out to determine the optimum percentage of asphalt cement needed by our hot mixes and in this way we proceeded to manufacture pavers of 8, 7 and 6 cm. Cobblestones with recycled asphalt mixtures were tested 2 days after they were made, and concrete pavers were tested after 28 days to reach maximum strength. An articulated pavement was designed with pavers of hot asphalt mixtures with recycled aggregates, knowing the values of the thicknesses of each layer that forms an articulated pavement the cost analysis of articulated pavements with pavers of hot asphalt mixtures was performed, which He noticed a low value with respect to simple concrete pavers.
