水泥混凝土路面具有承载能力大、稳定性好、使用寿命长、日常养护费用少等优点,是高等级、重交通公路路面的主要类型之一。在我国积极发展水泥混凝土路面,对合理利用水泥资源,提高路面使用质量和寿命,缓和沥青供应不足的矛盾,增加公路高等级路面铺筑里程,都具有重要意义。现从水泥混凝土路面的特点进行分析,着重说明了路面脱空这一水泥混凝土路面特有病害形成的原因。
Cement concrete pavement has the advantages of large carrying capacity, good stability, long service life and low daily maintenance costs. It is one of the main types of high-grade and heavy traffic pavement. Active development of cement concrete pavement in our country is of great significance to rational use of cement resources, improve the quality and life of the pavement, ease the contradiction between the supply of asphalt and increase the pavement mileage of high-grade pavement. Now from the characteristics of cement concrete pavement analysis, focusing on the pavement emptying of the cement concrete pavement disease-specific causes.
