Ketahanan Deformasi Campuran Beraspal Modifikasi Polimer Hangat Dengan Bahan Aditif Zeolit Alam

Abstract

Polymer modified asphalt mixture can be developed using warm mix technology by adding the mixture using synthetic or natural additives. This mixture can increase the deformation resistance with lower temperature in the process of mixing and compaction. This study proposes the development of warm Polymer Modified Asphalt mix with natural zeolite, which is natural additives from Bayat (Central Java), and the performance of the mixture, in terms of volumetric and mechanical properties, and deformation resistance, which was evaluated using the Marshall method and wheel tracking test. The results showed that the Polymer Modified Asphalt mix with 1 % of natural zeolite have a Marshall stability greater than that of Polymer Modified Asphalt mix without zeolite. Wheel tracking test at 60 °C shows that Polymer Modified Asphalt mix with 1 % of natural zeolite showed better performance than that without zeolite
