Abstract

The use of additive Wetfix-Be additives in concrete asphalt mixture is an effort to improve the quality of the asphalt pavement. The aim of this study was to analyze the effect of the use of the additive Wetfix-Be additive to the performance of asphalt concrete wearing course mixture (AC-WC). This research uses asphalt penetration 60/70 with variations in asphalt content of 4.5%, 5.0%, 5.5%, 6.0% and 6.5%. Gradations are used based on the specifications required by the Department of Public Works of the Director General of Highways, so that the composition of aggregates for the mixture is obtained: coarse aggregate 37.26%, fine aggregate 18.89% and filler 6.37%. The test was carried out using the standard Marshall and Marshall Immersion methods. The results showed that the optimum bitumen content was 5.5% with Marshall stability values of 1579 kg (> 800 kg), VIM 4.82% (3% -5%) VMA 15.29% (> 15%), VFB 68.48 % (> 65%), Flow 4.23 mm (2-4 mm), MQ 381 kg/mm (> 250 kg/mm) and Immersion Index (IP) 94% (> 90%).
