MATERIAL CHARACTERIZATION FOR FLEXIBLE PAVEMENT CONSTRUCTION - A NEED FOR THE CONTRACTING INDUSTRY

This paper discusses various types of characterisation tests for assessing the suitability of materials before their use in flexible pavement construction. The details of the required tests are discussed with reference to Indian conditions. Pre-construction laboratory tests are listed on subgrade, base course materials, and bituminous layers, and for bituminous mix design. Field tests during and after construction are also listed. A methodology for the design of bituminous mixes is presented briefly, and its application to the Marshall method is described in more detail. The quality control tests, needed during and after construction, are outlined. The following applications and advantages of the material characterisation tests are envisaged: (1) use of locally available materials; (2) reduced construction costs; and (3) increased pavement life. The tests enable better management and use of materials for constructing flexible pavements and prolonging their life. The detailed procedure given here for laboratory testing can be conducted for a longer time on various materials. The statistical analysis of the results of longer tests can be informative and instructive, and help to maintain quality during construction.
