Abstract

THE EFFECT OF ADDING CORN STALK ASH TO MARSHALL CHARACTERISTICS ON ASPHALT AC-WC RAY NOFRIANDI 143110615 ABSTRAK In general, asphalt concrete mix is one of the flexible pavement constructions in the surface layer. The aggregate mixture consists of coarse aggregates, fine aggregates, and fillers. Materials commonly used as fillers in asphalt mixtures are stone ash, cement / pozzolan, lime and fly ash. Therefore there is a need for research using other alternative materials as a substitute for filler namely corn stalk ash which is waste from the processed corn stalk. The purpose of this study was to determine the effect of using corn stalk ash filler in AC-WC mixture. This research was carried out based on the Bina Marga Specifications 2010 (Revision 2) and and using the Marshall Test method. the percentage use of corn stalk ash filler are (100% stone ash), 75% stone ash + 25% corn stalk ash), (50% stone ash + 50% corn stalk ash), (25% stone ash + 75% corn stalk ash), (100% corn stalk ash). the testing results of the sieve analysis obtainable the percentage of coarse aggregate usage was 20.16%, medium aggregate 43.37%, rock ash 28.09%, sand 8.37% and asphalt content variation with a percentage of 4.0%; 4.5%; 5.0%; 5.5% and 6.0%. The optimum asphalt content is 5.7%. Based on the research, the use of corn stalk ash filler on AC-WC asphalt meets the Bina Marga Specifications 2010 (Revised 2) against the characteristic value of Marshall. The greater the percentage of corn stalk ash filler mixture, the lower VMA and VIM values. But the VFA and MQ values are higher. In the value of Flow and Stability, the value has increased and decreased, namely in the variation of filler (100% stone ash) to (50% stone ash + 50% corn stalk ash) the higher the value, but the value of stability and flow has decreased in the filler variation (25 % stone ash + 75% corn stem ash) to (100% corn stem ash) the value is getting lower. the maximum percentage of corn stalk ash filler mixture is obtained from a mixture of 50% stone ash + 50% corn stalk ash with a VMA value of 16.434%, a VIM of 3.880%, a VFA of 76.392%, a stability of 2529.413 kg Flow 3.52 mm and MQ of 719,264 kg / mm.
