Abstract

This paper describes the performance of asphalt concrete mixes that design by using Marshall Mix Design Method (AASTHO T245-90). The objective of this paper is to compare the performance of 50 blows and 75 blows laboratory compactive effort for pavement surface mix design according to the pavement densification phenomenon that might occur because of over compaction. The asphalt concrete wearing course, ACW20 mix design samples with selected blows laboratory compactions was tested according to AASHTO T283-89 'Resistance of Compacted Bituminous Mixture to Induced Damage' procedure. Mix design samples that used 50 blows showed slightly higher optimum bitumen content and higher tensile strength than 75 blows compaction. From the test results, it is shown that the higher compaction causes the decrease of asphalt film thickness that leads to reduced tensile strength ratio (TSR) value. However, in this study, both mix designs with different blows still fulfilled the Malaysia Standard Specification for Road Works requirement.
