Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H07L
Testing Crushed Stone, Crushed Slag, and Gravel for Single or Multiple Bituminous Surface Treatments (SC03)

This LTPP protocol covers the testing for the quality and size of crushed aggregate to be used in single or multiple bituminous surface treatments. All tests required by ASTM D1139-83, Standard Specifications for Crushed Stone, Crushed Slag, and Gravel for Single or Multiple Bituminous Surface Treatments will be completed in accordance with ASTM D1139 with the following exceptions:

  1. Resistance to Degradation will be determined in accordance with AASHTO T96-87I.
  2. Unit weight will be determined in accordance with AASHTO T19-88I, using the rodding procedure described in paragraph 7.
  3. Sulfate Soundness will be determined in accordance with AASHTO T104-86I using Sodium Sulfate.
  4. Sieve Analysis will be determined in accordance with LTPP Test SC10, H14L.
  5. Clay Lumps and Friable Particles will be determined in accordance with AASHTO T112-87I.
  6. Lightweight pieces will be determined in accordance with AASHTO T113-86. The liquid will be a zinc chloride solution with a specific gravity of 2.0.
  7. No measure of flat or elongated pieces is required.

The results will be recorded on LTPP Test Sheet H07.
