Application of reclaimed clay brick aggregate to cement stabilized gravel
In order to analyze the feasibility of the application of reclaimed clay brick aggregate in pavement base,the influence of reclaimed brick aggregate on the mechanical strength of cement stabilized crushed stone was studied,the optimal dosage of reclaimed brick aggregate was proposed,and the growth law of the mechanical strength of cement stabilized crushed stone with brick aggregate was studied under the optimal dosage.The results show that the maximum dry density and unconfined compressive strength of cement stabilized gravel first increase and then decrease with the increase of 0~4.75mm brick powder content.When the brick powder content is 35%,the maximum strength increases by 23.9%.With the increase of 4.75~31.5mm reclaimed brick aggregate content,the strength of cement stabilized gravel increases by 23.9%.The unconfined compressive strength decreases gradually.When the content is about 33%,the maximum content of reclaimed brick aggregate is recommended to be 68%.At this time,the strength of reclaimed brick aggregate cement stabilized gravel is the same as that without construction waste.
