Study of Mineral Powder Effects on the Performance of an Asphalt Rubber Mixture
This study was conducted in-depth study by doing several more important road performances of asphalt rubber mixture through laboratory tests. Firstly, comparing the relationship of the content of mineral powder and asphalt bitumen membrane thickness at different asphalt content, through film thickness to determine the range of gradation and asphalt content in laboratory tests. Grade 1 and Grade 4 asphalt content 5.5%, 6.0%, and 6.6% are set for the benchmark, then mixes adhesion, anti-damage, and fatigue properties of the test are carried out in the established range, the study found that: with the addition of mineral powder, asphalt film thickness decreases, but the adhesion of modified Cantabro test is influenced little by mineral powder added to the asphalt or not; whatever the grade adding 6.5% mineral powder or not, TSR values were greater than 80%, which meet regulatory requirements, but without mineral powder grade slightly better; fatigue properties of asphalt rubber mixture will reduced, when mineral powder added in, especially when the asphalt content is high.
