ABSTRACT
Polymeric-stabilization of pavement materials has demonstrated many added advantages over cement-stabilizations. They include the non-time dependency at the mixing stage and superior sustainability outcomes. Therefore, attempts have been made to assess the strength and stiffness of pavement foundation materials stabilized with a synthetic Polyacrylamide based Additive (PAM). Strength and stiffness relevant tests have been carried out using unconfined compressive strength and indirect tensile tests to assess the improvement of PAM-stabilized pavement materials. Pavement materials tested herein consist of three types of soils used for pavement construction in Australia. The experimental test results showed a significant increase in strength and also an exceptional tensile stiffness improvement.
