路面水泥混凝土的试配强度与验收标准的探讨

ON the Reoquired Average Strength of Pavement Concrete and Its Acceptance Criterion

本文作者认为,把试配强度作为验收标准是不妥当的,也是不经济的。本文通过抽样正态分布理论求解,得知强度评定合格系数随样本的增多而加大。

The auther found out that it is not justfied to take the required average strength of concrete as an acceptance criterion in the concrete pavement construction. The results obtained in this paper based on the samplingnormal disribution show that the evaluation criterion of strength qualificationincreases with the sample size.
