Test and Stability Analysis of Local Cold Regeneration Ratio of Used Cement of Ash Crushed Stone
The application of stable in-situ cold regeneration technology of used ash crushed stone can improve the environmental protection effect,optimize the pavement structure and improve the stability of highway engineering.Based on this,combined with the construction prac-tice of a road project,the paper analyzes the local cold regeneration ratio test and stability of used cement of ash gravel.The results show that the 7-day unconfined compressive strength increases with the increase of cement content when the old material gradation is determined.The use of 4.5%cement can avoid reflection cracks and ensure strength and stability without significantly increasing construction costs.
