Title: Control Standard for Compaction Quality of Rock-filled Subgrade Based on Settlement Ratio
Abstract: In order to enhance the strength and stability of subgrade and avoid adverse effect of the uneven deformation on subgrade,the relationship among settlement ratio,density and void ratio of rock-filled subgrade was studied by the method of surface settlement.It is found out that for rock-filled subgrades with thickness less than 40 cm,the settlement ratio should be within 3%;for those with thickness less than 60 cm,the settlement ratio should be between 3%and 5%.The results indicate that the standard of subgrade compaction based on settlement ratio could control the quality of rock-filled subgrade effectively.
