Apart from CR from used tires as an asphalt additive, natural rubber (NR) is another alternative additive for asphalt modification. The rubber used can be latex, cup lump (CL), technical rubber (such as crumb rubber), or used rubber from used tires. The use of latex with a dry rubber content >60% recommendation for asphalt modification additives. This latex can reduce the sensitivity of bitumen to temperature, increase resistance during use, and even distribute rubber in the mixture. Still, this process requires a large amount of latex and a long pre-treatment [7]. CL's addition increased the asphalt's softening point but significantly decreased its penetration and ductility [8]. Use of block skim rubber (BSR) and crumb rubber standard Indonesian rubber (SIR 20), cemented in open mills. This mastication treatment can reduce the Mooney viscosity, speed up mixing time, and increase the asphalt's softening point [9]. The use of activated rubber from used tires as an asphalt additive also increased asphalt softening points [10]. The polymer as an asphalt additive has several disadvantages, including degradation, oxidation, and susceptibility to free radicals in rubber, which accelerate asphalt aging. Many studies with various other additives have reported minimizing the aging of rubber modified asphalt [2]. The addition of 4-6% _w/w_ nano-silica and 4% _w/w_ diatomite gives an effect as an oxidation inhibitor. It protects the bitumen from oxygen, but the increased cohesion after adding nano-silica and diatomite makes the asphalt susceptible to rutting and fatigue [11]. The use of 1-2% _w/w_ Irganox 1010 and Dilauryl Thiodipropionate (DLTP) tends to make the asphalt binder soft so that the asphalt sensitivity to low temperatures decreases, and the asphalt is prone to rutting [12]. Many additives have been used and studied to inhibit the oxidation of polymer asphalt mixtures. Still, the addition of other additives has an impact on reducing the mechanical performance of polymer bitumen. The use of solid rubber, such as crumb rubber, will take a very long time in the mixing process, so a depolymerization process by chewing is required [9]. Mastication is the process of changing the physical properties of rubber from elastic to plastic. During mastication, the finished polymer chain breaking is due to shear forces by the rolling mill. This process results in a decrease in the molecular weight and viscosity of the rubber. The most efficient mastication process is carried out at temperatures below 60-70 \({}^{\circ}\)C and above 120-130 \({}^{\circ}\)C [13]. The mastication process can take place faster by adding a plasticizer as a rubber softener. Asphalt is used as a plasticizer to save rubber asphalt production costs. Compounds derived from hydrocarbon oil are very suitable for use as plasticizers for natural rubber types. Asphalt is a hydrocarbon oil compound, so it is ideal for plasticizers for natural rubber [14]. Based on these studies, there are several conclusions that the modification of asphalt using various types of natural rubber has a positive effect on improving the quality of asphalt. But the use of natural rubber is also susceptible to degradation, oxidation, and the formation of free radicals, which accelerate the premature aging of the asphalt. Based on this study, this study aims to make asphalt with high durability, resistance to low or moderate temperatures, resistance to rutting, and to prevent premature aging of asphalt. This study used solid natural rubber creep rubber with the addition of antioxidants 1,2-dihydro-2,2,4-trimethyl-quinoline (TMQ). This research will study the effect of adding creep rubber and antioxidant TMQ on modified asphalt characteristics.
