水麻高速公路隧道进出口部分路面特殊设计

Special Design for Pavement at Entrance and Exit of Shuifu-Maliuwan Expressway Tunnel

隧道洞口是明暗交接的地方,视觉上的突变导致汽车驶入或驶出隧道时发生交通事故几率较高。针对隧道洞口的特点,选择CRM薄层环氧抗滑层作为铺装材料。性能检测表明,该CRM薄层环氧抗滑层耐久性好,阻燃和耐化学腐蚀性能强,选用的红色石料能对驾驶员提出警示,特别适用于隧道洞口铺装。介绍云南水麻高速公路隧道洞口CRM薄层环氧抗滑层的铺装距离设计。

The entrance and exit of tunnel are the places with junction of brightness and darkness,the mutation of vision leads to high probability of traffic accidents when automobiles drive in and out of tunnel.The CRM thin epoxy antiskid layer is adopted as paving material in accordance with the features of entrance and exit of tunnel. The performance detection shows that the CRM thin epoxy antiskid layer is in good endurance,high flame retardance and chemical corroding resistance.The selected red stone aggregate is especially suitable for paving of entrance and exit of tunnel because of its alert for drivers.This paper introduces the design for paving distance of the CRM thin epoxy antiskid layer at entrance and exit of tunnel on Yunnan Shuijang—Maliuwan Expressway.
