隧道作为交通的咽喉要道,自建设以来,其行车事故不断发生,且事故损失是相当严重的,因此隧道的行车安全问题一直是隧道建设的主要关键点,且越来越被重视。隧道内外路面光照度、温湿度不同,长时间行车油污、尾气污染及车辆轮胎沾水导致路面湿滑等情况的存在,致使隧道路面的抗滑耐磨性能大幅降低,行车安全存在的重大隐患。传统的水泥混凝土和沥青混凝土在隧道施工当中都存在一定的缺陷,使得隧道施工当中急需一种低噪声、高抗滑的水泥路面施工方式来提高隧道路面的行车舒适性和安全性。在此背景下,露石混凝土因具有丰富的表观构造,大大提高了路面持久抗滑能力、同时路面集料的外露减小了滚动噪声、因粗糙表面对强烈的灯光形成漫反射而消除了炫目现象,提高了行车的安全性能。较为适宜在隧道铺面中得到应用。
Since the construction of the tunnel, the traffic accident has occurred constantly and the accident loss is quite serious. Therefore, the traffic safety of the tunnel has always been the key point of tunnel construction and has been paid more and more attention. Tunnel light intensity inside and outside the road, temperature and humidity are different, a long time driving oil, exhaust pollution and tire wetting caused by the existence of the road wet conditions, resulting in the tunnel road surface anti-slip wear performance significantly reduced traffic safety major hidden dangers. The traditional cement concrete and asphalt concrete have some defects in the tunnel construction, making the tunnel construction in urgent need of a low-noise, high anti-skid cement pavement construction methods to improve traffic comfort and safety of the tunnel pavement. In this context, due to its abundant apparent structure, the exposed concrete has greatly improved the long-term anti-skidding ability of the pavement, while the exposed aggregate of the pavement reduces the rolling noise, which is eliminated by the diffuse reflection of the rough surface by the intense light Dazzling phenomenon, improve the driving safety performance. More suitable for application in the tunnel pavement.
