Unbound granular pavements

To maintain competitiveness in the global market and service to the community, unbound granular pavements will continue to provide the majority of the pavement network in the foreseeable future. How unbound granular pavements work is reasonably understood theoretically but there is a considerable deficiency of test methods, calibration of the methods and models, material source date and quality control mechanisms. Additionally, the optimum economic solution involves the use of local materials that requires individual and frequently one off development. This is significantly different to the emerging global optimum where lower transport and communication costs results in greater concentrations of the development and manufacturing components of a product. Future delivery of unbound granular pavements will involve the introduction of not only more science but calibration of the properties and the models and development of source specific specifications. This paper describers the delivery model and the use of the available science in the new specification. (a) For the covering entry of this conference, please see ITRD abstract no. E211649.
