RAP掺量对热拌再生沥青混合料性能的影响研究

Study on the impact of RAP mixing amount upon hot-mixing reclaimed asphalt mixture performance

阐述了热拌再生沥青混合料再生机理,对不同RAP掺量的沥青混合料的高温性能、水稳性能、疲劳性能以及低温性能等路用性能进行了试验,试验结果表明,掺加了适量RAP的沥青再生混合料能满足路用性能的要求。

The paper describes the recycling mechanism of hot-mixing reclaimed asphalt mixture, and tests the road performance of different RAP mixing amount asphalt mixture upon high-temperature performance, water stability performance, fatigue performance and low-temperature per- formance and so on. The testing results show that： suitable RAP mixing amount reclaimed asphalt mixture can meet the road performance demands.
