Characterisation of Road Base Course Materials: The Effects of Waste Material Inclusion and Layering

Abstract

This research provides a comprehensive study of the static and dynamic behaviours of rock with various materials and different techniques for use in pavement applications. An improvement in dynamic behaviour of rock was associated with the glass, cement and slag presences. The stiffness of rock/rubber mixtures was found to be affected by the glass addition. Moreover, artificial intelligence approaches appeared a high ability to develop a model to predict resilient modulus of base and subbase.
