Experimental Study and Application of Recycled Aggregate in Road Base Material
The recycled water stabilized base material is prepared by using waste water stabilized recycled aggregate from highway milling instead of natural aggregate,and the engineering application is carried out.The results show that for the waste water stabilized recycled aggregate from the same road,its drying or non-drying treatment has little effect on the optimum moisture content of recycled water stabilized mixture.The optimum moisture content is generally about 4％～5％higher than the water absorption of recycled graded aggregate.For the waste water stabilized recycled aggregate from different road,the higher its crushing value,the lower the unconfined compressive strength,splitting tensile strength and compressive rebound modulus of recycled water stabilized aggregate.The performance of recycled water stabilization is comprehensively considered.The recycled fine aggregate from Road 1 and the recycled coarse aggregate from Road 3 are selected to mix in proportion to prepare the recycled water stabilized materials for engineering practice.The recycled water stabilization has good mechanical properties and pavement performances,which can meet the requirements of engineering design,and has good application effect.
