Influence of replacement Portland cement with white limestone powder from Madura as filler on hot asphalt mixture (hot mix) Asphalt Concrete Wearing Course (ACWC) on Marshall characteristic

Abstract

Road pavement layers are essential road construction that supports traffic loads, and as infrastructure that connecting one place to another and used by society should have good quality pavement, excellent performance and comfort serviceability to human movement in transportation. As is known filler has term and condition specification in Bina Marga General Specification (Edited Version 3) (2010), the added filler requirements consist of limestone dust, Calcium Carbonate, CaCO3, or lime dust by AASHTO M303-89 (2006). While the lime powder that has used as filler is according to the test results from the chemical engineering laboratory, ITS Surabaya pure white limestone Madura is a waste of natural lime rock containing Calcium Carbonate (CaCO3) as much as 58.46%. It will be seen from the value of stability and flow by using Marshall Test Performance by combines mixture of asphalt-aggregate with filler of white lime powder of Madura with difference of asphalt content 5,5%, 6% and 6,5% and variation of content filler 0%, 1%, 2% 3% and 4% on mixed Asphalt Concrete Wearing Course (ACWC). From the result of the testing and analysis of Marshall, the replacement Portland cement with white limestone powder on asphalt concrete wearing course layer are finding combine of asphalt content 5,5 %, 6,0% and 6,5% and higher levels of filler in asphalt mixture shows the higher value stability while the value of flow decrease with increasing value of filler content in the asphalt mixture. Based on the value of the variation filler that meets specifications Marshall 4% white limestone Madura and 6% asphalt content as the proportion that meets all of Marshall parameter value.
