ROUT AND SEAL CRACKS IN FLEXIBLE PAVEMENT : A COST-EFFECTIVE PREVENTIVE MAINTENANCE PROCEDURE

The objectives of this study were to ascertain the cost-effectiveness of the rout and seal procedure based on the successful treatment of the distress, the resultant extension of pavement service life, and the optimum timing for application of this treatment to achieve maximum cost benefit. Implemented in 1986 across the province of Ontario, the study ensures complete coverage of different climatic and environmental conditions. Monitoring of the treatment performance and pavement condition has been completed for a period of three winters. From the data, it has been established that certain rout configurations are more effective in different regions of the province; the rout and seal treatment effectively delays or even stops progressive distress deterioration; the treatment is essential to achieve maximum cost benefit, with the optimum time being from the 3rd to 5th years for initial treatment, and the 8th to 9th years for follow-up treatment.
