Unpaved (Gravel) Road Ratings – IBR
Hard Surface Road Ratings are collected in Lapeer County approximately every 5-years. The Road Ratings for unpaved (gravel) roads are collected utilizing the Michigan Transportation Asset Management Council (TAMC) data collection regulations. TAMC has adopted the Inventory Based Rating (IBR) system for measuring conditions of unpaved roads in Michigan.
Unpaved Roads are assessed on three (3) Road Features – Surface Width, Drainage Adequacy and Structural Adequacy. The baseline of what is acceptable to most road users is a “Good” assessment. Not meeting the baseline condition results in a lower assessment (Fair and Poor) based on ranges of physical characteristics.
