Aggregate Sampling - ASTM D75 Standard Practice for Sampling Aggregates

Involves the field sampling of various aggregate stockpiles according to ASTM Standards. Samples are taken back to the laboratory for testing.

Nuclear Density Tests - ASTM D6938 Standard Test Methods for In-Place Density and Water Content of Soil and Soil- Aggregate by Nuclear Methods (Shallow Depth)

This test allows for the measurement of the in-situ moisture content and percentage compaction in the field using a nuclear density gauge with sealed radioactive source and detector and predetermined laboratory compaction values. The gauge allows for testing of various layer thicknesses up to 300 mm.
