Our accredited facilities can perform full Marshall control testing and a wide range of asphalt, bitumen and road-readiness services, according to any standard you require.
Used to determine the stability and flow of compacted asphalt briquettes with an electronic plotter.
Known as BRD, this test determines the density of the hot mix asphalt mix after compaction.
Compaction of asphalt samples to target mixture or void content to determine mixture compatibility and design properties.
Evaluate the surface condition of pavement. Measures surface roughness, texture and transition irregularities and surface rutting.
The most practical system to accurately measuring pavement’s deflection response when subject to a dynamic load.
Measure surface roughness, texture and rutting to calculate ride comfort, surface friction and noise generation.
One of 13 world wide, this allows us to simulate traffic, moisture and temperature effects on a pavement layer, recreating real-life stresses.
Samples can be tested to determine their susceptibility to rutting and moisture against different load, temperature and moisture settings.
Used to determine the rideability of a specific road surface area and measure the transition between where processed sections join.
A hot mix asphalt sample is placed into a pycnometer and a vacuum pump removes all air from the sample to determine the mix density.
Used to determine the percentage of binder in the hot mix asphalt sample. Sample is washed and processed to ensure no aggregate material is lost.
Used to determine the percentage of binder in the hot mix asphalt sample. Final weight is compared to the starting weight to determine loss.
Used to accurately determine the net bitumen content of a slurry mixture.
Used to determine the shear-rate and apparent viscosity of bitumen.
Simulating the hardening properties of bituminous binders during mixing, transportation and compaction.
This test method is used to determine the elastic properties of a polymer modified bituminous binder.
The penetration of a standard ball into bitumen-rubber measures the relative hardness or consistency of bitumen rubber blends.
Measures the rubber crumbs' contribution to a bitumen rubber blend’s ability to return to its original shape after compression.
This test is used to measure the flow properties of bitumen at high temperatures.
Used to simulate the embedment of stone chips that occurs during construction and under traffic loading.
This test is used to determine the texture of a road surface, also known as the roughness.
The permeability of a bituminous layer indirectly indicates the material’s susceptibility to the ingress of water.
Certification of a binder distributor, validation of binder distributor dipstick, power and speed indicator test, pump system performance, and transverse distribution.
Used as a measure of the consistency of bituminous materials. Higher values of penetration indicate softer consistency.
Useful in the classification of bitumen as one element in establishing the uniformity of receiving shipments of binder.
Measures the water present in the emulsified asphalt as distinguished from either bitumen or petroleum solvent.
