摘要
通过马歇尔试件燃烧试验和模型隧道中沥青混凝土路面燃烧试验,分别对沥青混合料受火源直接影响以及高温环境中的炙烤影响进行分析研究,并提出了隧道中沥青混凝土路面的面层防火最小设计厚度建议。
In order to study the security performance of asphalt mixture m tunnel pavement, through the Marshall test sample burning test, combustion experiments of the asphalt pavement in Tunnel Model and the theory temperature analysis technology of road surface in burning test, the influence of the directly fire source and the high temperature environment on the asphalt mixture are analyzed and studied. The minimum firepoof surface design thickness of asphalt concrete pavement in the tunnel road is proposed.
