Accelerated Loading Facility (ALF)

Simulation testing

ALF Triaxle

The Accelerated Loading Facility (ALF) is used to simulate heavy vehicle trafficking on pavement structures under controlled conditions.

The ALF allows pavements to be tested and for their performance to be evaluated in a very short time compared with test sites under normal traffic.

The original ALF was developed in Australia by the Roads and Traffic Authority of New South Wales. A number of long term pavement performance (LTPP) studies have verified ALF results against pavement performance under real traffic and environmental conditions. The Australian ALF has been used for more than 250 experiments over 25 years, applying over 32 million load passes and simulating well over 300 million Equivalent Standard Axle loads.


  • Rank relative performance of materials or processes
  • Investigate parameters used in pavement design
  • Provide support for road construction activities such as full scale proof testing
  • Assist with development of network deterioration models
  • Enhance full scale long term monitoring studies
  • Building capacity and expertise

Research labs

ARRB’s investment in materials laboratories over 60 years fulfils a commitment to research, innovation and pioneering experimentation in bituminous binders, asphalt and granular pavements. Our state-of-the-art world class laboratories are equipped with a wide range of equipment capable of providing comprehensive testing of these materials.

ARRB research labs

The new 1,200 m2 laboratories at our national headquarters in Port Melbourne provide a platform for applied research focussed towards solutions for current and future materials technologies. The integration of the office space and the design of the laboratories, including 182 m2 of bench space, provides effective workflows and superior capacity. The design of the laboratories also allows for flexible working areas for future research needs.

Our laboratories are instrumental in the development of test methods for Australia (Characterisation of the Viscosity of Reclaimed Asphalt Pavement (RAP) Binder Using the Dynamic Shear Rheometer (DSR), Characterisation of Flexural Stiffness and Fatigue Performance of Bituminous Mixes, Permanent Deformation Characteristics of Unbound Granular Materials by the Wheel-tracking test) and provides fundamental assessments of new and innovative technologies (EME2, crumb rubber asphalt).

In combination with a stringent quality assurance program and ISO/IEC 17025 NATA accreditation, the ARRB independent laboratories are highly specialised facilities that provide world class results with the utmost precision and accuracy. Our laboratories also offer hands-on training of students, technology transfer to the state road authorities and industry, advanced pavement research techniques, and are a national reference resource.
