Asphalt Mixtures Modified with an Elastomer (Rubber) and an Elastomer (Milk Bag Strips with 80-100 Asphalt).

Abstract

The addition of industrial products such as rubber and plastic may constitute a pavement structure by providing asphalt mixes with better mechanical behavior and more durability. We have to be conscious that we live in the culture of using and throwing away, and in the trash of each day there are many resources that we are wasting, it is important for all of us to put in action the three “R”, reduce, reuse and recycle. By carrying out this research project we hope to achieve a reduction in the solid waste residues and additionally to improve the performance of the pavements in Colombia. In this investigation of asphalt mixtures modified with rubber and plastic, we made the dynamic characterization of the mixture with the optimal addition of plastic origination from markets of milk bags and of rubber originating from used tires, achieving a reduction on rutting of 8%, an increase of the dynamic modulus of 14%, which means for a mechanistic design of pavements an increase of 25% in durability.
