盐化物沥青混合料在高速公路罩面工程中的应用研究

Salt Antifreezing Asphalt Mixture Cover Application in Highway Engineering

盐化物沥青路面是指将具有抑冰效果的盐化物按照一定比例加入到沥青混合料中,并结合一定的摊铺工艺将其摊铺成具有抑冰效果的路面。论文结合某高速公路罩面铺筑工程,详细讲述了盐化物沥青混合料的高温稳定性、低温抗裂性和抗水损害能力,提出了盐化物沥青混合料组成设计和在路面施工过程中需要注意的事项,可对类似盐化物沥青混合料应用工程起到借鉴作用。

salt asphalt pavement refers to the salt with ice suppressing effect in a certain proportion is added to the asphalt mixture, and combining with the paving process and the paving suppression effect of pavement with ice. Based on a highway overlay paving project, describes in detail the papersummed high temperature stability of asphalt mixture, low temperature crack resistance and anti water damage ability, and puts forward some matters needing attention in the design and construction process of road salt antifreezing asphalt mixture, hoping to provide useful reference to sirnilar engineering application of salt antifi^eezing asphalt mix up.
