前言随着我国改革、开放政策的全面推进,商品经济的蓬勃发展,城乡交流的日益活跃,人民生活水平的不断提高,使公路交通量迅速增长,大型客车和重型货车也日益增多,从而对公路路面的结构强度和使用性能提出了更高的要求。为适应公路运输发展对路面的要求,重要的途径之一是积极发展水泥混凝土路面。水泥混凝土路面具有强度高、稳定性好、耐久性好、使用寿命长、养护费用少等优点。但一般认为其初期投资大,由于接缝的原因
Preface With the comprehensive promotion of China’s reform and opening-up policy, the vigorous development of the commodity economy, the increasingly active exchange of urban and rural areas and the continuous improvement of people’s living standard, the traffic volume of the highway has been rapidly increased, and the number of large-sized passenger cars and heavy trucks has also been increasing. Pavement structural strength and performance requirements put forward higher requirements. One of the important ways to meet the requirements of pavement for the development of road transport is to actively develop the cement concrete pavement. Cement concrete pavement with high strength, good stability, durability, long life, less maintenance costs. However, it is generally believed that the initial investment is large due to the seams
