泡沫沥青冷再生基层力学性能的试验研究

The Study on the Mechanical Performance of Cold Recycling Base with the Application of Foamed Bitumen

对现场泡沫沥青冷再生基层的力学性能进行了研究,主要内容有根据泡沫沥青的性能指标确定了泡沫沥青的制备条件;根据国内对基层强度的要求和国外的规程,进行了无侧限抗压强度试验和间接抗拉劈裂强度试验,确定了最佳泡沫沥青用量,评价了泡沫沥青冷再生基层的力学性能。

The mechanical of cold recycling base with the application of foamed bitumen was studied, and production condition of foamed bitumen was determined based on its performance index; optimum foamed bitumen contents were determined according to unconfined compression strength test and indirect tensile splitting strength test based on the request of base strength at home and foreign regulation; the mechanical performance of cold recycling base with the application of foamed bitumen was also evaluated.
