泡沫沥青冷再生基层的力学性能试验研究

摘要

According to the foaming principle and performance of foam asphalt,and the gradation of asphalt mixture,the preparation conditions of foam asphalt are determined.Through Marshall Com-paction test,the optimum moisture content and asphalt dosage are obtained.According to the split-ting strength test and the unconfined compressive strength test,the mechanical property of foam as-phalt is evaluated.It provides a reference for the research on foam asphalt cold regeneration technolo-gy at the grass-roots level.%根据泡沫沥青的发泡原理、发泡性能及混合料级配确定了泡沫沥青的制备条件。通过马歇尔击实试验得到泡沫沥青最佳含水量和沥青最佳用量，并依据劈裂强度试验和无侧限抗压强度试验的结果，评价了泡沫沥青的力学性能。
