摘要
针对北京地区公路特点,结合工程实例,依靠室内试验分析对4种盐化物融雪沥青混合料融冰雪、路用性能开展性能检测,配合新机场高速路面工程试验段试验结果,确定样品1、样品2盐化物作为新机场高速抗凝冰路面外掺剂。最后,按照铺筑施工工艺,控制质量相关措施,验证应用效果。
According to the characteristics of the expressway in Beijing area,the influence of different salinization materials on ice melting performance and road performance of asphalt mixture were studied combining with engineering example.According to the test results of the new airport expressway pavement engineering test section,the sample No.1 and No.2 salinization materials are determined as the admixture of the new airport expressway anti-freezing ice pavement.Moreover,the quality measures were controlled based on the paving construction technology.Finally,the application effect was verified.
