Michigan's Inventory-Based Rating System For Unpaved Roads, Peter Torola
Michigan's Inventory-Based Rating System For Unpaved Roads, Peter Torola
Purdue Road School
The current rating systems for unpaved roads lack stability and reliability and, therefore, provide little benefit as project- or network-level metrics. Since many of these systems are derived from paved-road assessment systems, they focus heavily on surface distresses rather than road width, drainage, and other features. This session presents the Inventory-Based Rating System as a stable and implementable method of condition assessment for unpaved roads, without the focus on surface distresses.
