Sampling
Getting a sample that represents the material: sampling and reducing aggregates, asphalt mixtures, binders and emulsions, and taking pavement cores.
Pavement Cores
Drilling, handling and testing cores from asphalt and concrete pavements for density, strength and thickness, and the rules that keep core results comparable.
Sampling and Reducing Aggregate Samples
Taking representative aggregate samples from belts, streams, roadways and stockpiles, then reducing them to test size by splitter, quartering or mini stockpile.
Sampling Asphalt Binders and Emulsions
How asphalt binders and emulsions are sampled from tanks, transports and distributors, which containers to use, and how to avoid contaminating the sample.
Sampling Asphalt Mixtures
Where and how to sample loose asphalt mixture at the plant, from trucks and behind the paver, and how to reduce the sample to test size without segregating it.
