Public test guide

Choose a test to understand what it does.

Each test opens a plain-language page explaining what is used, what is measured and how the result supports a project decision.

Asphalt binder content

Measures how much bituminous binder is present in an asphalt mixture.

Asphalt bulk relative density and voids content

Measures specimen density and calculates the air spaces remaining in compacted asphalt.

Asphalt core drilling

Recovers a cylindrical sample from a completed asphalt layer for direct measurement and testing.

Asphalt creep modulus

Measures time-dependent deformation of asphalt under a sustained or repeated load.

Asphalt indirect tensile strength

Measures resistance to splitting when a cylindrical asphalt specimen is compressed across its diameter.

Binder absorption

Estimates the amount of binder absorbed into aggregate pores rather than remaining as effective coating.

Bitumen ductility

Measures how far a shaped bitumen specimen can stretch before breaking under controlled conditions.

Bitumen penetration

Measures the hardness or consistency of bitumen by the depth a standard needle enters under controlled conditions.

Bitumen-rubber ball penetration and resilience

Measures indentation and elastic recovery characteristics of a bitumen-rubber blend.

Bitumen-rubber compression recovery

Measures how a bitumen-rubber specimen recovers after being compressed.

Bitumen-rubber flow test

Assesses the flow or consistency behaviour of a bitumen-rubber blend under a controlled test condition.

Immersion Index

Compares asphalt strength before and after controlled water conditioning.

Marshall Stability and Flow

Measures the load resistance and deformation of a compacted asphalt specimen at a controlled temperature.

Maximum theoretical relative density — Rice method

Determines the density an asphalt mixture would have with no air voids.

Moisture in asphalt

Determines the amount of water present in an asphalt mixture or related material.

Recovery of binder from asphalt

Separates bituminous binder from an asphalt mixture so the recovered material can be tested.

Riedel and Weber binder adhesion

Assesses how strongly bituminous binder remains attached to aggregate in the presence of water.

Ring-and-ball softening point

Measures the temperature at which bitumen softens to a defined degree.

Rubber-crumb bulk density

Measures the mass of loose rubber crumb occupying a known volume.

Rubber-crumb grading

Measures the particle-size distribution of rubber crumb used in bitumen-rubber blends.

Rubber-crumb resilience

Measures the rebound or elastic response of rubber crumb used in modified binders.

Slurry design

Selects proportions of aggregate, emulsion, water and additives for a workable and durable slurry surfacing mixture.
