ABSTRACT

The use of Lawele Granular Asphalt (LGA) in Cold Paving Hot Mix Asbuton (CPHMA) as an alternative to oil asphalt has been attracting the interest of researchers and practitioners. However, it still has some weaknesses, one of which is finding a suitable modifier for LGA. LGA requires other materials as modifiers that release bitumen from the LGA minerals. The function of the modifier is not only to dissolve the bitumen of LGA but also to modify the LGA compounds to produce better pavement. Several studies have examined alternative modifiers, one of which uses candlenut oil. Research on the performance of candlenut oil applied to CPHMA has been conducted. The testing is still limited to mechanical tests, where the results depend on many factors, one of which is the process of extracting LGA bitumen. The results obtained prove that candlenut oil has the potential to be a modifier for CPHMA, not only capable of dissolving LGA bitumen but also increasing the quantity of dissolved bitumen with the increase in the storage duration of the mixture, up to 137.8% based on the Marshall test results.
