| Abstract: | This article analyses the theoretical principle of the cement concrete shrinkage and expansion during the curing period. The authers try to find the reason of the concrete shrinkage cracks during construction period and the concrete frictional force under the moving loading. The paper presents a new technology of preventing cracks on cement concrete road surface and concrete sawed joint timing. |
