Change of Pavement Concrete Properties After Dry-Wet Circulation
In order to analyze the performance change of road concrete in the dry-wet circulation environment,the relevant indoor tests are designed by using the theoretical knowledge,the variation regularity of the rebound value,sound velocity value and compressive strength value of different strength grades of concrete with the increase of the number of dry-wet circulation is analyzed,the surface strength of concrete increases with the increase of the number of circulation,although the increase is smaller in the later period,it still has an upward trend;if the internal density of concrete is higher,the corresponding sound velocity is faster,the concrete strength obtained is also high,and the influence of dry-wet circulation on the compressive strength of concrete with higher strength grade is smaller.
