OPEN-GRADED MIXES: BETTER THE SECOND TIME AROUND

Open-graded asphalt friction courses (OGFCs)--or open-graded mixes--are earning rave reviews from motorists. The "popcorn" type surface is a benefit to drivers because water is virtually eliminated from the surface, preventing tire spray and hydroplaning. New polymer modifiers have provided the stability to these mixes that was lacking initially, and the result is that pavement owners and builders are taking a second look at OGFCs. This article describes the composition of OGFCs--uniform aggregate, minimum fines--and the initial costs associated with placing this longer life surface. The Oregon Department of Transportation's use of OGFCs is highlighted as they have led the nation in using these mixes. Discussions on noise reduction and pavement life are included also.
