| 摘 要： | 为了对采用双层连续摊铺和间断摊铺2种方式的沥青混合料路用性能进行对比,通过模拟现场施工方式,同时制作2种级配组合的双层马歇尔试件和双层车辙试件.在常温、低温及冻融3种试验条件下进行不同摊铺方式的沥青混合料劈裂、剪切、弯曲等性能测试.结果表明:双层连续摊铺的沥青混合料所有路用性能均好于间断摊铺的沥青混合料.

| Abstract: | In order to compare the pavement performance of two kinds of asphalt mixtures with the continuous paving and discontinuous paving, two kinds of double layer Marshall specimens and two layer rut specimens were prepared with different gradation combinations by simulating on site construction methods at the same time. The performance tests of splitting, shearing, bending of asphalt mixture with different paving methods were carried out under the conditions of normal temperature, low temperature and freeze thaw. The test results show that the pavement performance of double layer continuous paving asphalt mixture is better than that of the discontinuous paving asphalt mixture. |
