Research on Application of Warm Mix Asphalt Technology in Central Plant Hot Recycled Engineering

Abstract:

The warm mix asphalt technology was introduced to breaks through the low reclaimed asphalt pavement (RAP) ratio in central plant hot recycled engineering. Firstly, performance tests for traditional hot mix asphalt and central plant warm recycled asphalt mixture with different RAP ratios (0%,40%,50%,70%,100%) were conducted. It was concluded that the performance of warm mix asphalt was as good as hot mix asphalt, and the RAP ratio could increase to 60% by central plant warm recycling technology. Then a practical central plant warm recycled engineering with RAP ratio 50% was analyzed. It was concluded that not only the performance of the recycled asphalt mixture met the standard requirements absolutely, but also the compaction quality of the recycled pavement was improved.
