Determining the Foaming Characteristics of Bitumen
Foaming of bitumen permits the bitumen to be evenly distributed throughout a soil or a granular material. It is critical for the bitumen to remain as viable foam for a period to enable it to be successfully blended into the host material.
Resilient Modulus of Foamed Bitumen Stabilised Materials
This method describes the procedure for the laboratory determination of the resilient modulus of test cylinders of foamed bitumen stabilised mixes using repeat load indirect tensile techniques.
Mixing of Foamed Bitumen Stabilised Materials
This method describes the procedure for adding foamed bitumen to a granular material to produce foamed bitumen stabilised material. The method is applicable to materials with a maximum nominal particle size of 40 mm (i.e. 100% passing the 37.5 mm…
Compaction of Test Cylinders of Foamed Bitumen Stabilised Materials Part 1: Dynamic Compaction using Marshall Drop Hammer
This method describes the procedure for compacting cylindrical test specimens suitable for use in the determination of physical properties. The method is applicable to materials with a maximum nominal particle size of 40 mm (i.e. 100% passing the 37.…
Long-term Ageing Resistance of Bitumen using the Pressure Ageing Vessel (PAV) and the Dynamic Shear Rheometer (DSR)
This test method sets out the procedures for the ageing treatment of bitumen samples under specific conditions using the Pressure Ageing Vessel (PAV), and also the determination of the complex viscosity of treated samples under specific conditions…
Sample Preparation - Compaction of Asphalt Slabs
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…
Asphalt Particle Loss
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.
Asphalt Binder Content (Ignition Oven Method)
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.
Binder Film Index
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.
Field Calibration of Aggregate Spreaders
This method sets out the procedure for determining the spread rate of cover aggregate delivered from a mechanical aggregate spreader.
