Analisa Karakteristik Campuran Aspal dengan Lateks Terhadap daktalitas dan Stabilitas Pada Perkerasan Jalan

Abstract

In the world of road pavement, added materials are no longer foreign. The added material basically serves to improve the quality of the asphalt mixture. In this study using latex as an additive to the mixture because latex has elements that can support the asphalt mixture. And if the results are positive, this added material is highly recommended for the world of road pavement, especially in Indonesia, which is one of the largest rubber producing countries. The research was carried out by finding the optimal asphalt content (KAO) by making samples of asphalt content 5 - 7% first. After obtaining the KAO, latex was added with levels of 4% and 6% with a collision of 2 x 75. For the search for optimum asphalt content, the results showed good results because it met specifications, namely asphalt content 5%, stability value of 843 kg, asphalt content of 5.5% of 1010 kg, asphalt content of 6% of 1036 kg, asphalt content of 6.50 % as much as 1015 Kg, and 7% asphalt content of 825 Kg. The average value of stability in the search for the optimum asphalt content (KAO) indicates that the asphalt mixture meets specifications. However, the addition of latex content did not get good results. The average value of its stability does not meet the specifications where the average value for the addition of latex with a level of 4% gets the results of 656 Kg and 6% of 651 Kg. This result does not meet the minimum specification for the stability value of 800 Kg. And from this value it can be concluded that the more latex content, the lower the stability value. So that latex cannot be used as additives in the AC - WC mixture.
