Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H17L
Joint Sealants, Silicone (CS02)

This LTPP protocol covers the tests for silicone joint sealants for PCC pavements. The tests will be performed in accordance with Georgia DOT Standards Specifications, GA DOT 833.06, Silicone Sealants and Bond Breakers (Modification). A copy of the specification and test methods are given in SPS-4 Attachment G of the Manual for the SHRP Maintenance Effectiveness Study of Rigid Pavements (SPS-4).

The results will be recorded on LTPP Test Sheet H19.
