Thiopave沥青混合料性能评价

Performance Evaluation of Thiopave Asphalt Mixture

世界上硫磺供大于求的趋势在将来近二三十年内不会改变,且硫磺的价格远远低于沥青,应用Thopave沥青混合料可以有效降低混合料成本。通过马歇尔、车辙、低温弯曲和冻融劈裂试验对Thiopave沥青混合料性能进行评价,试验结果表明,Thiopave沥青混合料可以有效减少沥青用量,降低成本,提高混合料的高温性能,但是Thiopave沥青混合料的低温性能较普通沥青混合料差,且需要通过添加抗剥落剂来增加其抗水损坏性能。

The trend of the worldwide sulfur oversupply will not change in the future twenty or thirty years, and the price of sulfur is far low than asphalt, so Thiopave asphalt mixture can reduce the cost of mixture. Marshall, Rutting, Low - temperature bending test and Freeze - thaw splitting test are done to evaluate Thiopave asphalt mixture, the results show that Thiopave asphalt reduce the dosage of asphalt, lower the cost, enhance high temperature performance, but its low temperature performance is had than ordinary asphalt mixture, and anti - stripping agent is need to enhance the resistance of water damage.
