A synthesis of applications of the MLS as an innovative system for evaluating performance of asphalt materials in pavement engineering

The purpose of this paper is to provide a succinct synthesis of innovative applications of the Mobile Load Simulator (MLS) test system applicable to bituminous pavements. The extensive volume of reported applications of the system during the past fifteen years serves as a reference base validating it as an innovative testing system. A synthesis of facets of analyses and findings from the wide range of selected case studies applicable to bituminous pavements was done. These include MLS applications in laboratories and in the field. Also MMLS3 applications in conjunction with other full-scale trafficking equipment such as, the Accelerated Loading Facility (ALF), Heavy Vehicle Simulator (HVS) and WesTrack and NCAT vehicular test tracks. The MLS system comprises the one-third scale MMLS3 and the full-scale MLS10 and MLS66 in conjunction with various supplementary devices such as the Portable Seismic Pavement Analyser (PSPA), a heating and cooling system, a wet trafficking system, surface profilometer, contact surface stress measurement with foil pressure cells and a system for extracting specimens from compacted slabs for testing mix properties. Applications include evaluation of permanent deformation and susceptibility to moisture damage of bituminous road paving mixtures, fatigue evaluation, testing of composite pavement systems including reinforced asphalt and cement treated material layers and other aspects of pavement engineering systems and products.
