Release Date: 1989
The existing pavement condition rating systems used in Ontario are designed only for hard surfaced roads. To date, there has been no system designed and developed specially to address the unique performance pattern of gravel surface roads. This document was prepared to meet this need and to present a roadway surface condition rating system for gravel surface roads. The manual covers the rating system, distress manifestations, procedures for roadway evaluation, surface defects, surface deformation, and shoulder distress manifestations.
