Impact of Construction Waste on Cement-stabilized Road Base Materials
To promote the waste-free treatment of construction waste,this paper processes the bricks and concrete,which constitute the largest proportion of construction waste,and adds them as recycled aggregates to the cement-stabilized road base.Through raw material tests,compaction tests,unconfined compression tests,splitting tests,water stability tests,and freeze-thaw cycle tests,it was found that recycled coarse aggregates had adverse effects on the unconfined compressive strength,splitting strength,water stability,and frost resistance of the cement-stabilized base.The properties of recycled brick aggregates were worse than those of recycled concrete aggregates,but their strength could meet the requirements of the specifications for cement-stabilized materials for secondary and lower-grade roads.The need for frost protection in winter should be considered during engineering applications.
