International registrants who attended the 2013 International Friction Workshop, hosted by the Thomas D. Larson Pennsylvania Transportation Institute from May 13 to 16 at Penn State, were shown Blastrac’s 2-4800DH ride-on shot blasting system and its effective surface preparation technology. The workshop is part of a research initiative to revise existing American Society for Testing and Materials (ASTM) specifications for the calibration and quality assurance of continuous friction measuring devices. Research is warranted due to the number of friction measurement devices used today for the assessment of surface conditions on highways and airports is numerous, with a significant number of design and operational differences. ASTM governs most of the standards under which this equipment operates.

Josh Jones, Blastrac’s transportation market manager put on a live demonstration, showing how this surface prep machine strips, cleans and profiles, simultaneously improving skid resistance by enhancing micro/macro textures. The 2-4800DH has a 48 in. (122 cm) blast pattern cleaning path.

Surf Prep Inc. of Milwaukee, Wisc., was instrumental in delivery and supplied a 2-4800DH from its working fleet so that it would be available for demonstration.
