Performance Evaluation of a Polymer Binder Stabilized Aggregate Mixture: A Pilot Study

In this pilot study, a new polymer binder based on carbamate linkages was evaluated for use with unbound aggregates to create a stable mixture for roadways, parking lots, and airport pavements. The binder is trade named “G5.” An extensive laboratory evaluation of the mechanical properties of the G5-stabilized aggregate mixture was conducted using the latest advancements in materials testing. The designed mixture was evaluated for stiffness using the dynamic modulus (E*) test and for its resistance to rutting using the flow number (FN) test, reflective cracking using the overlay tester (OT), thermal cracking using the uniaxial thermal stress and strain tester (UTSST), and fatigue cracking using the flexural beam fatigue test. In summary, the evaluated G5-stabilized aggregate mixture exhibited unique characteristics with superior performance at high, intermediate, and low temperatures suggesting a very good performance in the field when used as a surface course layer. The data showed that the evaluated G5-stabilized mixture may offer excellent alternatives when used as a surface layer in hot climate areas with heavy traffic and/or braking actions. The mixture is also anticipated to perform very well when used in cold climates and/or on top of a cracked asphalt pavement due to its high resistance to reflective and thermal cracking.
