Study on vibratory mix technology and performance of cement-stabilized crushed stone

Compared with traditional mixing method, vibratory mixing technology used in cement-stabilized crushed stone can greatly improve the uniformity and strength of cement-stabilized crushed stone. This study conducts the research on the performance of cement-stabilized crushed stone by using vibratory mixing technology. The research contents include: principle analysis of traditional and vibratory mixing; determination of maximum dry density and optimum water content of cement-stabilized crushed stone; test of compressive strength and split strength of cement-stabilized crushed stone based on vibratory mixing. Research results show that the compressive strength and split strength of cement-stabilized crushed stone meet the requirements of specification. Application of vibratory mixing technology can obtain the better economic and social benefits.
