THE INFLUENCE OF BINDER PROPERTIES ON THE WHEEL-TRACKING RATE OF ROLLED ASPHALT

The binder has an important role to play in the performance of bituminous materials, particularly in rolled asphalt where the mechanical properties of the binder have a strong influence upon the mechanical properties of the mixture. The use of polymer additives to improve the behaviour of bitumen is an increasingly popular route to achieving improved performance from bituminous materials, but there are many different types of polymer modifiers available with potentially different properties. In the USA, the Strategic Highways Research Program (SHRP) has proposed various dynamically measured rheological parameters which are claimed to predict mix performance. The SUPERPAVE (SUperior PERforming PAVEment) is the final product of the SHRP asphalt research programme. It is a mixture design and analysis system with a new approach of specifying asphalt mixture gradations. This paper examines the relationship between binder properties and the wheel-tracking rate of those binders in one particular aggregate grading with particular emphasis on assessing the universal validity of the SHRP criterion.
