摘　　要：大空隙沥青路面混合料,通过连续开级配增大空隙率,获得更强的抗滑、降噪、排水能力,因而在设计、施工等方面均有较普通路面更高的要求。基于此,文章研究了大空隙沥青路面混合料配合比设计方法,并对混合料排水、降噪性能和路用性能进行了验证,结合某市政道路积水严重段试验路的铺筑效果,提出了施工关键技术。The asphalt pavement mixture with large voids increases the void ratio through continuous open grading to obtain stronger skid resistance,noise reduction and drainage capacity,so it has higher requirements than ordinary pavement in design and construction.Based on this,the paper studies the mix proportion design method of asphalt pavement with large voids,and verifies the drainage,noise reduction and road performance of the mixture.Combined with the paving effect of the test road in a municipal road with serious water accumulation,the key construction technologies are proposed.
