摘要
我国为多山国家,由于山区道路工程的特殊性对路面材料提出了更高要求。多孔水泥混凝土作为一种新型路面材料,具有良好排水性、抗滑性和降噪性等优点在各等级公路得到了广泛应用。文中针对山区公路病害形成特点展开分析,论述了多孔水泥混凝土材料在山区公路中特殊路段(长坡、急弯、路肩及凹型竖曲线)和山区公路隧道中应用的必要性,为多孔水泥混凝土路面在山区公路合理应用提供参考。
China is a large country with a lot of mountains. The particularity of mountainous has put forward higher requirements on the pavement materials. Porous concrete as a new material with unique skeleton gap structure,good performance of reduction and drainage is used in all grades of highways. Based on the mountainous characteristics,the paper analyzes the phenomenon of the water damage,descended skid resistance,bad environment in the tunnel,and elaborates the necessity of reasonably applying porous concrete in the special sections( long slope,sharp turn,shoulders and concave vertical curve) and tunnel,which provides references for the use of porous concrete in the mountainous.
