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.

This method details the determination of the binder content of asphalt mixes by ignition at a temperature of not less than 540°C and the subsequent determination of the particle size distribution by sieve analysis.

This test method sets out the calculation procedures for the determination of a Binder Film Index. The test is applicable to all types of asphalt.

This method sets out the procedure for determining the spread rate of cover aggregate delivered from a mechanical aggregate spreader.

This method describes the procedure for the determination of the quantity of binder absorbed by an aggregate. The volume of aggregate is determined from its bulk particle density in a saturated surface dry condition. The volume of binder free…

This standard sets out the method for determining the Average Least Dimension (ALD) of aggregate particles by the use of vernier callipers or dial gauge or a slotted gauge. The method is applicable to aggregate of nominal size 10 mm and greater for…

Asphalt characterisation tests require equipment that is well maintained and correctly adjusted. The procedures described in this document will provide a means of verifying that a Gyropac gyratory compactor is in a suitable working condition to…
