CORRECTING FLEXIBLE PAVEMENT DEFICIENCIES: THE ONTARIO WAY

Ontario emphasizes preservation of their highway system by carrying out maintenance activities aimed at prolonging the life of highway pavements. To make the maintenance task easier and more effective, a set of guidelines was developed that helps maintenance staff make the best decision, one that is most cost-effective and one that is made consistently by different maintenance staff. For the most part, the guidelines deal with short-term measures - deficiencies that have to be fixed right away, that is, corrective maintenance. But they can also be used to identify situations where preventive maintenance will affect the service life of the pavement. The guidelines contain the following elements: 1) identification process, 2) treatment selection, and 3) performance standard. The paper describes the current practice of identifying and classifying a typical deficiency, selection of the most cost-effective treatment, the specifications for equipment and materials needed to carry out the treatment, and the proper work methods. As a typical example, this paper will describe flexible pavement crackings and cracks that are routed and sealed as the prescribed treatment.
