Marshall Characteristics of Quicklime and Portland Composite Cement (PCC) as Fillers in Asphalt Concrete Binder Course (AC-BC) Mixture

Abstract

Quicklime and Portland Composite Cement (PCC) were used in a concrete-asphalt mixture (C-AM) combination to compare quicklime and Portland Composite Cement (PCC). The Marshall characteristics test was used to discover the distinguishing characteristics of a hot asphalt mixture made of quicklime and Portland composite cement (PCC) to make asphalt-type Asphalt Concrete Binder Course (AC-BC). This study used petroleum bitumen with a 60/70 penetration and bitumen contents of 5.0%, 5.5%, 6.0%, 6.5%, and 7.0% created by combining quicklime and cement in a filler. In this study, quicklime and cement were used as fillers; both materials have been used to create concrete buildings and have demonstrated their strength. To determine values for stability and density, Marshall tests were run. The Marshall technique of 2 x 75 blows was used in this study to get the necessary road materials, which were obtained in the composition of asphalt concrete binder course, in accordance with the Indonesia 2018 General Specification and the Indonesia Requirement (in Indonesian). The results showed that the filler quicklime at the optimum bitumen content (OBC) 6.5% had stability Marshall 873.9 kg, VIM 3.9%, VFB 76.63%, flow 3:33 mm, Marshall Quetiont 262.16 kg/mm, and VMA 16,49%, whereas the filler cement had stability Marshall 905.5 kg, VIM 4.1%, and VFB 76.57%, Hot mix asphalt with cement filler works better than quicklime filler. for building using intermediate layers (asphalt-concrete binder course).
