水泥混凝土路面主要依靠面层承受行车荷载的作用,因此面层泥凝土的强度是决定路面结构承载力和使用寿命或者确定面层所需厚度的关键因素。同时,混凝土强度与耐磨性、抗冻性、抗渗性等性能有着密切关系。在分析影响混凝土强度的有关因素的基础上,讨论各种强度指标值之间的经验转换关系,阐述混凝土的强度特性。
Cement concrete pavement mainly rely on the surface to withstand the role of traffic load, so the strength of the surface layer of concrete is to determine the pavement structure bearing capacity and service life or to determine the thickness of the key factors required surface layer. At the same time, concrete strength and wear resistance, frost resistance, impermeability and other properties are closely related. On the basis of analyzing the relevant factors that affect the strength of concrete, we discuss the empirical transformation relations between various strength index values and expound the strength characteristics of concrete.
