我国公路水泥混凝土路面建设发展速度很快,截至2003年底已经建成各级水泥混凝土路面18.7万公里,每年在建的水泥路面在2.25万公里以上,建设规模巨大。由于目前国际上沥青供应总量有限,且运费过高,而我国水泥资源又十分丰富,因此,水泥混凝土路面在可预见的一定时期内仍将是公路路面的一种重要形式。水泥混凝土路面具有强度高、刚度大、使用寿命长、初期养护费用低等优点。缺点是一旦出现损坏,维修极其困难,尤其是在交通量大、车速快的高速公路上,板块维修尤显复杂。

China’s highway cement concrete pavement construction has enjoyed rapid development. As of the end of 2003, it has built 187,000 km of cement concrete pavement at all levels, and more than 22,500 km of concrete pavement is under construction each year, with a huge scale of construction. As the current international asphalt supply is limited and the freight rate is too high, and our cement resources are very rich, therefore, the cement concrete pavement will remain an important form of highway pavement for a foreseeable period of time. Cement concrete pavement with high strength, stiffness, long life, low initial maintenance costs. The disadvantage is that in the event of damage, repairs are extremely difficult, especially in the case of heavy traffic and fast motorways, where the repairs are particularly complicated.
