Abstract

Increasing traffic volume which is increasing rapidly can result in a level of damage such as deformation of the road surface layer caused by the influence of excessive traffic load (overload), it is necessary to have a good quality pavement mix planning. Latex is a type of natural rubber which has high resistance to cracking and has high wear resistance. Improve the quality of the asphalt mixture with the addition of natural rubber (latex) as an additive which is expected to improve the characteristics of the pavement. Meanwhile, for the use of fly ash filler, each additional level results in a lower flow value, therefore this study is expected to produce a better HRS-WC pavement mixture.This study aims to determine the effect of variations in the number of collisions and also the feasibility of latex as an added material, fly ash as a filler in the HRS-WC layer. With a variation of the collision 2x65,2x70,2x75,2x80,2x85.The test results of the effect of variations in the number of collisions on Marshall characteristics that have been carried out produce a value that meets the specifications set by the Public Works Office of Bina Marga 2018 including testing: aggregate absorption test 2.89%> 3%, specific gravity 2.29 gr / cm2> 2.5 gr / cm. Obtained a stability value of 946.82 kg, a flow value of 3.54 mm, a VIM value of 4.06%, a VMA value of 17.29%, an MQ value of 270.54 kg / mm, a VFA value of 76.39% So that the optimum number of collisions is 76. Thus it can be declared that it meets the requirements of the HRS-WC specification.
