After four years of heavy trafficking, the test section demonstrated significantly less surface distress, cracking and improved ride quality. The county elected to use GlasGrid8511TF to manage their portfolio of road assets and recently completed a successful 5-mile reconstruction by removing 5” of existing HMA, applying 12” of full-depth reclamation with 5% cement, 4” of aggregate base, one 2.5-inch lift of HMA, GlasGrid8511TF, a 3” lift of HMA topped by a 1.5” wearing course of course of Weld County road 77.
