Analysis of Wear-Coated Asphalt Concrete (AC-WC) Modified With Addition of Steel Slag and Resin for Road Conditions Inlowed In Tide

Abstract

Causes of damage to road construction, among others due to the influence of excessive vehicle traffic loads, temperature, water (puddles), and pavement construction that does not meet technical requirements. Water (puddle) is one of the causes of damage or reduces durability for road construction with asphalt pavement. This study aims to examine the effect of asphalt mixture (AC-WC) with the addition of resin and steel slag aggregate on asphalt stability (AC-WC), Obtain Job Mix Design (JMD) for road conditions that are inundated by high tide and Assess the effect of immersion rob water against asphalt resistance (AC-WC) with the addition of resin and steel slag.In this research, it can be said that we play a role and participate in building prosperity in the advancement of transportation and the development of technological civilization, through continuous research that is adjusted to continuous research. We carry out research with the aim of developing science and technology and applying the reconstruction of science and technology to provide solutions to be able to solve environmental and societal problems, where local wisdom forms the basis of research.The research method used as a mix tester is the Marshall method, where from the Marshall test the results are obtained in the form of Marshall components, namely the volume weight of the test object, the value of stability, flow, voids in the mix (VIM), voids in mineral aggregate (VMA), void filled with asphalt (VFA), the thickness value of asphalt blanket or film and then can be calculated Marshall quotient. The last test was in the form of a Marshall immersion test. In the comparison of VIM, VMA and VFA above that for aggregate slag 25%, 50% and resin addition 5%, 7%, 10%, for resin content 5% and 10% did not meet specifications, however for 7% resin content meets the 2018 Revised Highways Technical Specifications. Based on the marshal test, there was only one that met the specifications of the binamarga, namely a test object with a resin composition of 7% by soaking for 7 days. The results of this study based on the Marshall test, the strength/stability value of the AC-WC asphalt mixture using a pen 60/70 asphalt mixture with steel slag and resin mining met the specifications. The stability value of asphalt AC-WC decreased with increasing variations in the resin content used in the mixture.
