ONTARIO FLEXIBLE PAVEMENT DISTRESS ASSESSMENT FOR USE IN PAVEMENT MANAGEMENT

A method is described which is used in Ontario to assess the condition of the pavement at any time. The condition rating assigned is based on subjective judgement of riding quality, and the appearance of rutting and distortion, surface defects, and cracking. The guidelines used for assisting the rater in the assessment process, include typical descriptions of eight different stages in the life of a pavement, and a catalogue of photos and descriptions. A method is also described of calculating the pavement condition rating from measured roughness values and from the standard terms used to describe the visual observations of distress. The weighting for distresses used in these calculations was established from iterative correlations with subjective condition ratings. The condition rating and the description of distresses are used in determining suitable alternative maintenance and rehabilitation treatments in setting priorities and in formulating rebabilitation programs.
