The effect of using asbuton with used waste diesel oil on the stability of the porus asphalt mix with hot mix cold laid method

Abstract

The abundant availability of Asbuton in Indonesia should be proportional to the percentage of its use, however, in the implementation of pavement works, it is still dominated by petroleum asphalt, the price of which tends to be higher than the Asbuton. If you look at the elements in Asbuton, namely minerals and bitumen, it should be superior to petroleum asphalt. One of the factors where the use of Asbuton is not optimal is that the stability value of the mixture using Asbuton is still low compared to the mixture using petroleum asphalt. So this research aims to analyze the stability value of the porous asphalt mixture using Asbuton and waste oil as a rejuvenating agent with hot mix cold laid method. The research method was carried out by carrying out test objects with variations in Asbuton content of 5%, 5.5% and 6% with variations in fuel wastage rate of 0%, 2%, 3% and 4%. The total number of test objects is 36 samples. Then the Marshall test was tested to determine its stability value. The results obtained based on the test results are the highest average stability value at the variation of the levels of Asbuton 6%, 5.5% and 5% respectively 1295.3 Kg with 4% waste oil content; 1238 Kg with 3% used oil; and 773 kg with a waste oil content of 2%. Adding the Asbuton content increases the stability value; however, the level of used oil in the best results still varies. It can therefore be concluded that the highest stability value of a hollow asphalt mixture using an Asbuton content of 6% and a waste oil content of 4% with a value of 1295.3 Kg, meets the specification of the Road Engineering Association of Malaysia (REAM).
