PERFORMANCE OF HIGH RATIO RECYCLED PAVEMENTS IN NORTHERN ONTARIO ---PROCEEDINGS OF THE THIRTY-SECOND ANNUAL CONFERENCE OF THE CANADIAN TECHNICAL ASPHALT ASSOCIATION

The Ontario Ministry of Transportation and communications began hot mix recycling as a standard asphalt pavement rehabilitation alternative in 1980. To provide the greatest economy, the earliest recycling contracts used a high ratio of reclaimed material (as much as 70%), asphalt cement as the only rejuvenator, and a single gradation Virgin aggregate. This paper reviews the design, construction and performance of five early recycling contracts, four of which were of the high ratio design, and outlines the ministry's current recycling design practice. Some of the observed problems with the early design included aggregate quality and gradation, contamination of the reclaimed material, poor performance of under-asphalted mixes and flushing of the recycled pavements.
