【摘要】 采用几种条件下处理过的沥青混合料试件在不同水温下的浸水车辙数据 ,说明了酰胺类抗剥剂的有效性。结果说明在试件经真空饱水冷冻浸水处理后 ,在水温 45℃下的车辙实验数据有较好的说服力。并用改进的洛特曼 ( Lottman)试验方法进行了对比 ,验证了此方法的合理性。更多还原

【Abstract】 Immersion wheel trucking test was used for proving the effect of antistripping agent in asphalt mixture.The rut samples were treated in different ways before the test and put in different temperature of immersion water in test.The result was reasonable when the samples were treated by vacuum saturation in 6600 Pa, then frozen to 18℃ and melt in 60℃ water, and were tested in water at temperature 45℃. The reasonableness was proved by Lottwan′s test.更多还原
