摘要 用自行研制的路面破冰模拟试验仪研究了橡胶颗粒沥青混合料路面的破冰能力,考察了不同橡胶颗粒掺量和不同温度下路面的破冰情况,提出了摆值加权平均回升量和摆值平均回升率的概念。结果表明,路面破冰模拟试验仪可用于进行室内冰雪沥青路面破冰能力的模拟试验;橡胶颗粒沥青路面比普通沥青路面更不易结冰,且橡胶颗粒掺量越高路面的抗滑性能越好;只有在一定的温度范围内橡胶颗粒沥青路面才具有良好的破冰能力;摆值加权平均回升量和摆值平均回升率指标可用于定量地描述路面的破冰能力。 The ice-breaking performance of pavement paved by crumb rubber modified asphalt mixtures was studied in a self-made simulation tester,and the effects of crumb rubber level and temperature on the ice-breaking performance were investigated.The results showed that the simulation tester could be used to test the ice-breaking performance of crumb rubber modified asphalt mixtures pavement with ice or snow in laboratory.The crumb rubber modified asphalt pavement was more difficult to freeze than common asphalt pavement,and the more the level of crumb rubber,the better the skid resistance of pavement.Only in a certain temperature range,could the crumb rubber modified asphalt pavement have good ice-breaking performance.The proposed rally amount weighted average of the British pendulum test number and rally rate average of the British pendulum test number could be used to describe the ice-breaking performance quantitatively.
