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.

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.

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…

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.…

This report examines the capacity of the extra-large wheel-tracking laboratory test method to predict the in-service performance of granular materials.

Rutting is a common distress mode of unbound granular bases under thin bituminous surfacings.
