摘要
在道路建设中,水泥混凝土路面的弯拉强度是一个关键指标,主要采用小梁标准试件和路面钻芯取样圆柱体劈裂强度折算的弯拉强度综合评定。对某高速公路的水泥混凝土路面进行弯拉强度与劈裂强度的对比试验,建立了弯拉强度和劈裂强度的换算关系式,用作工程质量验收的评定依据。
In road construction, the flexural tensile strength is a key index of cement concrete pavement. It can be comprehensive evaluated by calculating flexural tensile strength of girder style book and core cylinder. The experiment of bending strength with that of flexural tensile strength on a cement concrete pavement freeway is contrasted and established the conversion expression between bending strength and flexural tensile strength, which is the basis of this project＇s quality checking and acceptance.
