This webinar, presented on 29 August 2017, provides an overview of contemporary local and international incident management practices and a harmonised traffic incident management (TIM) framework that supports network operations planning. The…

Signalised interchanges and ramp metering are major components of the interface between the arterial road system and the motorway system. The control systems of motorways and arterials are often treated as separate control components, which can…

The current practice of balancing traffic density or distributing traffic evenly in a road network is essentially subjective and is achieved manually through expert opinions. This report summarises these expert opinions and investigates whether…

This test method describes the procedure for measuring the penetration depth of a standard steel ball into a road surface under the impact of a standard hammer.

This test method sets out the procedure for determining the amount of binder drain-off likely to occur in an asphalt mix during storage and transport. The method may be used to determine the amount of binder drain-off at the maximum mixing…

This method describes the procedure for the recovery of sprayed seal samples from the pavement without disturbing the sealing aggregate orientation. The method stipulates how the void content of the sample is determined.

This test method sets out the procedure for assessing the degree of absorption of a primer or primerbinder by a given road gravel in bituminous surfacing work.

This test method details the requirements for determining the flexural stiffness, phase angle, dissipated energy per cycle, cycles to failure and cumulative dissipated energy at failure of asphalt subjected to repeated flexure by cyclical four-point…

This method sets out recommended procedures for mixing, compacting, conditioning and trimming asphalt to provide homogeneous specimens suitable for wheel track testing, beam flexure testing, resilient modulus testing and other asphalt…

This test method sets out the procedures for determining particle loss (abrasion) from laboratory prepared specimens of open graded asphalt. The test may be performed on dry samples or after period of moisture conditioning.
