ABSTRACT
In order to reduce the use of crushed stone and cement in base course, Composite Soil Stabilizer Stabilized Gravel Soil (CSSSGS) has been gradually used in road construction. This paper presents details of a study that deals with determination of mechanical properties (unconfined compressive strength, splitting strength, compressive modulus of resilience and splitting modulus of resilience) and durability (water stability, freezing resistance, and shrinkage) of CSSSGS compared with Cement Stabilized Macadam (CSM) based on the target unconfined compressive strength (5 MPa). The study reveals that CSSSGS has the better mechanical properties (unconfined compressive and splitting strengths) than CSM, and the durability is close to that of CSM. The potential of CSSSGS for cracking resistance is good within 28 days of curing time. Overall, CSSSGS can be a alternative material for CSM, and this research provides a solid foundation for applying CSSSGS to entity projects.
