Abstract:

As documented in the project summary report, the existing slurry materials are not recommended for main lane applications because of an unacceptable drop in skid resistance. To address this a new specification is proposed and included in this tech memo. The main change with this test is the use of the 3-wheel polisher and Dynamic Friction Tester to demonstrate that the proposed slurry can retain 90% of its skid value after 10,000 applications of the polisher.
