水泥混凝土路面在其使用年限末期 ,不能再承担服务功能时 ,需要对其进行处理以建构新的路面结构。国内在旧水泥混凝土路面处理方面方法不够完善 ,这与我国机械设备制造工艺相对落后有关。国外 (主要指美国 )在处理旧水泥混凝土板块的过程中积累了丰富经验 ,形成了在旧水泥混凝土路面破损状况相对严重时的原位利用水泥混凝土路面的碎石化工艺。这一工艺能将水泥混凝土路面破碎成小粒径嵌挤颗粒 ,从而为新的沥青混凝土加铺层提供理想的基层。主要介绍国外水泥混凝土路面碎石化工艺状况及其设计方法。水泥混凝土路面碎石化的成套技术已经由山东省交通厅公路局倡导引进并开始进行试验段铺筑 Cement concrete pavement in the end of its useful life, can no longer afford service functions, they need to be processed to construct a new pavement structure. Domestic methods in the old cement concrete pavement treatment is not perfect, which is relative to the relative backwardness of China’s machinery and equipment manufacturing process. Abroad, mainly referring to the United States, has accumulated rich experience in the processing of old cement concrete slab, forming a crushed petrification process using cement concrete pavement in situ when the damage condition of old cement concrete pavement is relatively serious. This process can crush the cement concrete pavement into small-sized intruded particles to provide the ideal foundation for the new asphalt concrete overlay. Described the foreign cement concrete pavement crushing process conditions and design methods. The complete set of technology for crushing cement concrete pavement has been advocated by the Highway Bureau of Shandong Provincial Communications Department and started to be paved
