Study Asphalt Concrete Behavior Mixtures Using AC 6070 and PMA for Wearing Course

Abstract

Paving with asphalt concrete allows you to pave a surface more efficiently, more economically, faster and with greater serviceability than with any other paving material in road construction. This study was conducted to determine the engineering properties of the asphalt concrete material. The following tests were conducted in this research: aggregate properties of lime stone, stability, flow, and strength index tests: Asphalt cement penetration grade 60/70 (AC 60/70) and polymer modified asphalt (PMA) for heavy volume roads (herein, the equivalent standard axle load number is heavy), for wearing course. Results of aggregate tests such as abrasion, soundness, specific gravity, flakiness and elongation and sand equivalent were passed specification tests. The engineering properties of asphalt concrete mixtures using AC 60/70 and PMA found that density bulk, percent of VFB, stability and flow values increased​as the asphalt content increased. While the percentage of air voids and percent of VMA values decreases as the asphalt content increases. Strength index with AC 60/70 and PMA the compressive strength were 79.72 % and 86.05 %, respectively. We could be said that mixtures of asphalt concrete materials with PMA have superior properties more than with AC 60/70.
