Abstract

ABSTRACTIn the construction of highways, the community generally uses concrete asphalt as aningredient in the construction of highways. Asphalt concrete mix (Hotmix) use in Indonesiafrom year to year is increasing. Because concrete asphalt (Hotmix) has advantages comparedto other materials, for example, the price is relatively economical / cheap compared to usingconcrete, its ability to support heavy loads of high vehicles. the practicality of making asphaltconcrete (hotmix) can be made from locally available materials and has good resistance toweather changes. The purpose of this research is how the effect of adding lime extinguishedon mixed materials on asphalt concrete (hotmix) and knowing how much percentage of lime2mixture goes out to reach the optimum point of concrete asphalt from the author's calculationresults can be concluded as follows:1. The value of stability of each decrease by adding lime is 5% at 778 kg, 10% at 645 kg,15% at 534 kg.2. The results of the volume of air cavity to mixture (VIM) with levels of 5%, 10% and 15%,namely 8.17%, 7.51%, and 6.85%.3. Pore volume results between aggregate grains (VMA) with levels of 5%, 10% and 15%,among others, 19.87%, 18.55%, and 17.73%.4. Pore volume results between aggregate grains filled with asphalt (VFB) with levels of 5%,10% and 15%, among others 58.88%, 56.61%, and 54.35%.5. The results of the Marshall Quotient (MQ) value of 5%, 10% and 15% Marshall Quotient(MQ) are 297 kg / mm, 230 kg / mm, and 198 kg / mm.Keywords: Concrete Asphalt, Addition of lime extinguished, Marshall test characteristics
