Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H08L
Determination of Flakiness Index of Aggregates (SC04)

This LTPP protocol covers the procedure of determining the percentage by weight of particles whose thickness is less than three-fifths of their mean dimension. This test is to be performed on the aggregate to be used in the chip seal as part of the SPS-3 studies. This test will be performed in accordance with the Determination of Flakiness Index of Aggregates as described in "Asphalt Surface Treatments" (MS-13) dated January 1975 and "A Basic Asphalt Emulsion Manual" (MS-19) dated March 1979, by the Asphalt Institute.

The results will be recorded on LTPP Test Sheet H08.
