纳米抗剥落剂Zycosoil路用性能试验研究

Study of Nano-Antistripping Agent Zycosoil Performance Test Research

研究了纳米材料Zycosoil对沥青混合料水损害的影响.对具有代表性的两种集料类型石灰岩和花岗岩进行了评估.为评估Zycosoil对热拌沥青混合料水损害的影响,对照组混合料(无Zycosoil)和含有Zycosoil的混合料,在干燥和潮湿条件下进行了测试,使用间接抗拉强度(ITS)和间接拉伸疲劳(ITF)试验.结果表明,与花岗岩相比石灰岩具有较低的水损害可能.对两种类型的集料而言,含有Zycosoil的混合料ITST和ITFT的潮湿/干燥下值的比值高于对照组的值.然而,采用花岗岩集料的混合料采用Zycosoil后更加有效.

The effects of nanomaterial,namely Zycosoil on the moisture damage of asphalt mixtures were studied. Two types of aggregates that represent a considerable range in mineralogy,limestone and granite,were evaluated. To assess the impact of Zycosoil on moisture damage of hot mix asphalt,the control mixes without Zycosoil and the mixes containing Zycosoil in dry and wet conditions were evaluated using indirect tensile-strength（ ITS） and indirect tensile fatigue（ ITF） tests. The results show that limestone has less moisture damage potential compared to granite. The ratio of wet / dry values of ITST and ITFT for the mixes containing Zycosoil is higher than the control mix for two types of aggregate. However,the mixtures made of granite aggregate with Zycosoil is more effective.
