摘要
沥青路面的低温缩裂大多发生在寒流或寒潮突然来临时。在目前众多的评价沥青混合料低温性能的试验方法中,约束试件低温应力试验可以良好地反映沥青混合料的低温性能。根据不同地区气候的不同,提出基于降温急剧程度的自然区划,据此选择合适的沥青混合料,以期能更好地解决沥青路面低温缩裂的问题。
Most low temperature cracking of asphalt pavement occurs when the cold snap or cold wave comes. The themal stress restrained specimen test figures out the low temperature performance of asphalt mixture more effectively than the other available tests. According to the variety of climate in different area, climate partition based on cooling speed is made for proper asphalt mixture choosing. In this way, a better solution for low temperature cracking of asphalt pavement can be made.
