水泥混凝土路面简称混凝土路面，亦称刚性路面，俗称白色路面，它是一种高级路面。现广泛应用于飞机场跑道、高速公路、干线公路、城市道路、厂矿道路以及停车站场、隧道内路面和过水路面等。在通行多年后，水泥混凝土路面摩擦会衰减或出现断板、错台和接缝破坏等病害，对道路的安全性、畅通性带来极大影响。然而，水泥混凝土维修时间长，成本高，行车舒适性差，噪音大和易扬尘等缺点，越来越不能适应现代道路发展需要。 Cement concrete pavement is referred to as concrete pavement, also known as rigid pavement, commonly known as white pavement, it is a high-grade pavement. Now it is widely used in airport runways, highways, trunk roads, urban roads, factory and mine roads, parking yards, tunnel inner roads and water-passing roads, etc. After many years of traffic, the friction of the cement concrete pavement will attenuate or there will be diseases such as broken boards, wrong platforms, and joint damage, which will have a great impact on the safety and smoothness of the road. However, the maintenance time of cement concrete is long, the cost is high, the driving comfort is poor, the noise is large and dust is easy to be raised, and it is increasingly unable to meet the needs of modern road development. the
近年来，对水泥混凝土路面养护及维修改造技术的研究成为了热点，国内现普遍采取的方式是在水泥混凝土路面直接罩面、微表处、加铺热沥青等。然而在桥面受承重量及隧道限高等条件的制约下，上述方法不能适应其养护维修要求。特别是水泥混凝土路面结构在桥梁、隧道中的应用仍占较大比例，根据道路建设周期发展规律大部分路面状况已严重恶化，交通事故不断，那么寻求一种新技术对不良路面进行及时处理势在必行。 In recent years, the research on cement concrete pavement maintenance and repair technology has become a hot spot, and the methods generally adopted in China are directly covering the cement concrete pavement, microsurfacing, adding hot asphalt, etc. However, under the constraints of bridge deck bearing capacity and tunnel height limitation, the above methods cannot meet the maintenance requirements. In particular, the application of cement concrete pavement structure in bridges and tunnels still accounts for a relatively large proportion. According to the development law of road construction cycle, the condition of most road surfaces has seriously deteriorated, and traffic accidents continue. It must be done. the
