| 摘要： | The study involved testing and evaluating results on OSHD Class 'B' asphalt concrete. The study design focused on two types of potential mix design improvements. These were the effect of aggregate gradation and type of asphalt binder on mix properties. Several gradations were evaluated in four phases of testing. During each testing phase, several types of asphalts were used: rubber modified, polymer modified, and conventional AC graded asphalt. |
