一、概述混凝土抗折弹性模量E_w是计算机场混凝土道面、公路混凝土路面应力应变以及设计其厚度的重要参数之一。国内有关混凝土抗折弹性模量的研究只是近几年才开始受到重视,以往在计算机场道面厚度时,都引用苏联的抗折弹性模量数据。交通部第二公路勘察设计院在试验研 I. Overview The concrete flexural modulus E_w is one of the important parameters of the concrete pavement surface of a computer field, the stress strain of a concrete road pavement, and the design thickness. The research on the flexural modulus of concrete in China has only begun to receive attention in recent years. In the past, when the thickness of the road surface was used in the computer field, the flexural modulus data of the Soviet Union were used. The Second Highway Survey and Design Institute of the Ministry of Communications is conducting research and development
