SOME IMPROVED MATERIAL CHARACTERISATION TECHNIQUES FOR TESTING OF UNBOUND MATERIALS IN ROAD CONSTRUCTION

Unbound materials are in substantial use for road and airfield pavement construction. Improved methods of pavement design require that these materials should be characterised in terms of fundamental parameters. However there is no simple, inexpensive and practical method available for determination of the structural action, strength and deformation modulus of these materials. The most commonly used CBR method of testing and design, which is based on an arbitrary strength property of the material, has inherent shortcomings mainly due to the confining boundary effects of the mould. The paper briefly describes some of the improved testing techniques being developed at The University of Birmingham to investigate the part played by granular materials for their use as capping layers, sub-bases and road bases.
