Control the moisture content. In order to avoid the occurrence of artificial shrinkage cracks caused by improper control of the moisture content of the mixture, the moisture content of the mixture (the moisture content should exceed 1% of the optimal moisture content) should be strictly controlled in accordance with the relevant specifications. The expansion agent is added to the mixture. Using water reducing agent in cement stabilized particles can reduce the water content of mixture dry shrinkage crack. The addition of expansive agent can also reduce the shrinkage cracks of cement stabilized base. Add proper proportion of fiber into the mixture. Adding fiber material into cement stabilized macadam can improve the compressive strength. There are many kinds of steel fiber, such as steel fiber, plastic fiber, hemp, etc. Steel belt manufacturer
