Sets out methods of sampling asphalt from trucks at the mixing plant, at the paving site, and from the pavement. Also includes sampling of cold mix from stockpile. Not included are methods of sampling asphalt from the pavement (for determination of properties other than density) or methods of sampling at discharge points from asphalt mixing plants. In addition procedures for selection of sampling locations or the number of locations are not specified.

This standard sets out methods for obtaining samples and test portions of asphalt for the determination of the following properties:(a) Freshly mixed or supplied material:(i) Bitumen or tar content and aggregate grading.(ii) Moisture content.(iii) Bulk density, stability and flow properties of laboratory compacted specimens.(iv) Maximum density.(b) Placed and compacted material (core specimens):(i) Bulk density.(ii) Maximum density.
