Standard Practice for Preparation of Compacted Slab Asphalt Mix Samples Using a Segmented Rolling Compactor

Importancia y uso:

5.1 Asphalt slabs compacted with the rolling compactor can be used to obtain specimens for further testing, including bulk specific gravity following Test Methods D1188/D1188M, D2726/D2726M, and D6752/D6752M, fatigue performance characteristics following Test Methods D7460 and D8237 or AASHTO T 321, and Hamburg wheel-track testing following AASHTO T 324.

5.2 Specimens to perform other standard tests could also be obtained, as long as their volume is contained within the volume of a slab.

Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this practice are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline that provides a means of evaluating and controlling some of those factors.
