设计新的机场刚性道面,或者为评定机场现有刚性道面结构的承载能力,必须具有表征水泥混凝土抗折强度的统计参数,建立统计参数的有效途径之一,是利用施工过程中水泥混凝土厂实验室日常的混凝土梁的试验检测资料。 To design a new airport rigid pavement or to evaluate the bearing capacity of the existing rigid pavement structure at the airport, it is necessary to have statistical parameters that characterize the flexural strength of cement concrete. One of the effective ways to establish statistical parameters is to utilize the cement concrete Test data of the concrete beams in the factory laboratory.
