EVALUATION OF THE MECHANICAL PROPERTIES OF A HOT ASPHALT MIX MODIFIED BY DRY PROCESS WITH PLASTIC POLYPROPYLENE LIDS

Research output: Contribution to journalArticlepeer-review

Abstract

We report the evaluation of a hot asphalt mixture, conventionally used in the streets of Ecuador, modified with plastic polypropylene lids in order to improve their mechanical characteristics. The mixture has been modified using crushed waste from plastic bottle caps in an aggregate size equivalent to that retained in sieve number 8, which according to the ASTM standard is 2.36 millimeters. Marshall stability and flow tests were carried out on specimens fabricated with different percentages of polypropylene waste. It has been shown that the addition of polypropylene taps results in the improved Marshall properties. The results indicate that a modified asphalt mix has useful characteristics for a good performance as asphalt mixtures for paving.
