Abstract

Abstract

Cement-stabilized soil has the characteristics of poor durability generally. By a series of unconfined compression tests, compactness tests, dry wet cycle tests and CBR tests on cement-stabilized soil mixed with the super absorbent ploymers, the strength, compactness and durability of the cement-stabilized soil reinforced by SAP were analyzed and studied. The experimental results proved that: adding SAP could improve the unconfined compressive strength of cemented soil, up to 185% and improve the compaction characteristics of cement-stabilized soil, the optimal moisture content could be increased by 2%. With the increase of drying and wetting cycles, the mass loss of SAP-cement-stabilized soil could be reduced, while the unconfined compressive strength could be improved by 121%, which indicated that SAP could improve the durability of cement-stabilized soil; the CBR of specimens cemented with cement and SAP were slightly lower than that cemented with cement. Adding SAP could obviously improve many indexes of pavement performances for cement-stabilized soil and meet the requirements of subgrade fillings of high-grade highways.
