摘　　要：随着社会的发展,沥青路面的服务功能也日益提升,由最初单一的行车功能逐渐增加了舒适、环保等高级功能。常规沥青路面提升为舒适、环保型沥青路面时,通常需要往沥青混合料中添加一些创新材料才能实现。路面安全性是路面功能中首先要考虑的因素之一,仅凭传统的抗滑性能试验来评定掺入创新材料的沥青路面安全性不够严谨,易埋下隐患。笔者依托一种掺加纳米光催化材料的环保沥青路面,提出了一种新型沥青路面安全性评价方法,该方法从抗滑性能与反光性能两个角度来对新型沥青路面安全性进行评价,通过室内模拟试验对传统道路现场抗滑性能进行了室内测试,可有效预测新型沥青路面的抗滑性能;同时借鉴交通设施路面反光性能测试方法,对新型沥青路面光物理安全性进行了评价。可供参考借鉴。With social development, the performance of asphalt pavement is promoting from the initial driving function to gradually adding comfort, environmental and other advanced functions. Upgrading conventional asphalt pavements to a higher level of comfort and environmental usually requires adding some innovative materials to asphalt mixture.Pavement safety performance is one of key factors to be considered in pavement function. It is not scientific enough to evaluate asphalt pavement safety mixed with innovative materials only by traditional anti-skid capacity test and easy to plant hidden danger. In this paper, a safety evaluation method of new asphalt pavement was proposed based on an eco-friendly asphalt mixture with photocatalytic materials. The safety of new asphalt pavement was evaluated from two aspects of anti-skid capacity and reflection intensity. The field anti-skid capacity of traditional road was tested indoors by indoor simulation test and the one of new asphalt pavement can be effectively predicted. By referring to traffic facilities reflective performance testing method,light safety of innovative pavement was evaluated. It is available for reference.
