The smaller one third scale model mobile load simulator, Pave®MLS11 is an accelerated pavement testing tool applying realistic rolling wheel contact stresses. It can simulate wandering road traffic, environmental condition such as temperature and wet trafficking.


Developed as a tool for studying pavement performance. It supplements full-scale APT equipment and thereby reduces the overall cost of Accelerated pavement testing.

  • Prescreen specific pavement compositions
  • Evaluate performance of asphalt under wet trafficking
  • Evaluate performance of asphalt under high temperature trafficking
  • Investigate the impact of speed on performance of asphalt
  • Investigate fatigue of asphalt
  • Explore failure mechanisms
  • Evaluate asphalt designs and performance prior to and after construction
  • The MMLS3 can be applied in the laboratory and in the field

The application of the Pave®MLS11 has expanded world-wide and it is being used more and more by pavement engineers and technologists. In this regard.

In the laboratory

The full-scale MLS' have attributes that make them excellent tools for APT application, putting them in a class of their own. This includes:

  • Establishment of Transfer Functions for new pavement materials and layer systems in terms of a variety of failure modes
  • Pre-screening and ranking of full scale APT matrices prior to commencing full scale tests, in order to improve efficiency and cost-effectiveness
  • Development of acceptance criteria for mechanical tests for both mix designs and quality control testing, based on performance properties

In the field

  • Analysis of residual life of existing pavements, as well as rutting potential, in conjunction with GPR and SASW
  • Development of acceptance criteria in terms of rutting for newly constructed asphalt
  • Steps towards Performance Guarantee of newly constructed asphalt pavements
  • Assistance with long-term management of toll road pavements
  • The MMLS3 has many supplementary components in aiding an APT test which are all to be found in the MMLS3 brochure along with the in depth details of the MMLS3.
  • The supplementary components help in the following:
    • Environment control of the test section according to the users' need
    • Laboratory or field testing
    • Data capturing for rutting and stiffness
