Evaluación de las propiedades físicas de un asfalto 80/100 modificado con agregados de desechos de vidrio templado para su aplicación en pavimentos

Abstract

With climate change that generates extreme variations in temperatures, the roads are affected since a factor at the time of design is the climate and precipitation, this causes the rolling layer made with conventional asphalt to present a decrease in its useful life whose the consequence is greater extra costs in maintenance and repairs. The research project focuses on the evaluation of the physical properties of an 80/100 asphalt modified with ground tempered glass waste (GTGW), carrying out laboratory tests on each of the modifications made with different percentages of GTGW to determine which of all improve the characteristics of the asphalt. At the same time, using a non-recyclable material, contributing to the fulfillment of Sustainable Development Goals number 9 and 12, mitigating the environmental impact and creating more sustainable infrastructures. With the results of this project, it will be determined whether modifying the asphalt with GTGW generates an improvement in the physical properties compared to unmodified asphalt in order to prolong its useful life, as well as reducing costs in maintenance and repairs on the pavements. that can be designed based on this research. The results of the tests showed us a lower penetration which causes greater rigidity, on the other hand, the softening point increased, therefore, the road course would not present such frequent damage when it was implemented on the country's roads, prolonging the useful life of the pavement.
