The Clear Roads research program’s Qualified Products List (QPL) takes center stage in Episode 45 of AASHTO’s SICOP Talks Winter Ops podcast. Host Rick Nelson talks with Patti Caswell of Oregon DOT about the history and the future of the QPL, which was created by the Pacific Northwest Snowfighters consortium as a way to collectively test deicing chemicals and establish specifications for products that emphasize safety, environmental preservation, infrastructure protection, cost-effectiveness and performance.
The QPL is now managed by Clear Roads, which is nearing the end of a process to update procedures and product categories to make the QPL more transparent for both agencies and vendors. Caswell chairs the Clear Roads subcommittee that oversees the QPL.
