摘　　要：水泥砼路面具有抗压强度高、面层承载力强的特点,被广泛应用于长隧道与特长隧道。因隧道内部环境的特殊性,隧道路面抗滑指标存在衰减过快的问题。本文以广东EG高速隧道水泥砼路面处治为例,研究分析各性能指标变化情况。结果表明:HOG纹理化、精铣刨、Novachip、UHPP等四种养护措施均能快速提高隧道水泥砼路面抗滑性能;前两者可作为应急处治方案;后两者可作为长久处治方案。Cement concrete pavement is widely used in long tunnels and extra long tunnels because of its high compressive strength and strong bearing capacity.Due to the particularity of the internal environment of the tunnel,the anti-sliding index of the pavement decays too fast.This paper takes the cement concrete pavement treatment of Guangdong EG high-speed tunnel as an example to study and analyze the change of each performance index.The results show that four kinds of maintenance measures such as hog texturing,fine milling,Novachip and UHPP can rapidly improve the anti-sliding performance of tunnel cement concrete pavement;the first two can be used as emergency treatment plans;and the latter two can be used as a long-term treatment plan.
