Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H06L
Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test (SC02)

This LTPP protocol covers the test to indicate the proportions of clay-like or plastic fines and dusts in granular soils and fine aggregates. This test is intended to be used on the aggregates used in the slurry seals as part of the SPS-3 studies. The test will be performed in accordance with AASHTO T176-86, Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test, with the exception that the Mechanical Shaker Method (Referee Method) must be used.

Test results will be recorded on LTPP Test Sheet H06.
