Marshall Characteristic Of Asphalt Concrete Wearing Course Using Crude Palm Oil and Pen 60/70 As A Binder

Abstract

Asphalt is one of the non-renewable natural resources. It is necessary to conduct various studies regarding alternative materials can be used as a substitute for asphalt. Crude palm oil (CPO) has almost the same texture and properties as asphalt, when it is heated it will melt so it can be substituted as a binding agent in the AC-WC layer. Based on the background, this study aims to analyze the effect of 50% CPO substitution and 50% pen 60/70 on the AC-WC layer. This research is based on the Public Works Department General specifications in 2010 using the marshall method by varying 50% CPO and 50% pen 60/70. Variation of 50% CPO and 50% 60/70 pen get Asphalt Optimum Content (AOC) value of 4.5% from the test results of 15 test specimens and 6 specimens using AOC. The results of the test with a 30-minute immersion (stability) all the characteristics meet the marshall parameters that are implied, namely: a stability value of 842 kg, a Flow of 3.1 mm, a VIM of 4.64%, a VMA of 15.30%, a VFB of 69, 67% and the MQ value of 271.51 kg / mm. Marshall testing with a 24-hour immersion (durability) did not meet the specifications required so that this pavement is not durable.
