轮迹道路水泥混凝土弯拉强度试件尺寸及强度标准确定

Determination of the size and strength of cement concrete flexural tensile strength test specimens for Wheel Track Road

选取抗压强度等级为C30的混凝土,进行实体四个不同尺寸的小梁试验,结合水泥混凝土路面设计规范,对轮迹道路的设计标准进行研究,利用相似原理,得到轮迹道路的弯拉强度设计标准试件尺寸为107mm×107mm×421mm,进一步研究,得到弯拉强度设计标准值。

The concrete with compressive strength grade of C30 was selected to carry out the experiment of four different sizes of the beam, and the design criteria of the wheel track were studied according to the design specification of cement concrete pavement. Using the similarity principle, the flexural tensile strength of wheel track is obtained. The standard specimen size is 107mm ×107mm× 421mm. And the standard value of the tensile strength design is obtained through further study.
