In support of construction inspection performed by our in-house inspectors, R&M was responsible for soils and concrete testing. Field testing on soils included compaction density testing with oversize correction and soils sampling. We tested soils material in the field with a nuclear density gauge. Lab testing included gradations, proctors, hydrometers, coarse specific gravity and moistures. Concrete field testing included sampling, temperature, slump, unit weight, air content, and casting of concrete cylinders. Laboratory testing included compressive strength of the concrete cylinders.
