Pavement Rehabilitation with Cold Recycling Technology on Highway 8 (Queenston Road) in the City of Hamilton
The use of cold recycling technologies for pavement rehabilitation or structured reinforcement is popular among many agencies in central and southwestern Ontario. For suitable roadway candidates, use of cold recycled mixes yields environmental and economic benefits versus traditional surface rehabilitation or reconstruction techniques. The City of Hamilton has limited experience with incorporating recycled cold mix base courses in pavement structures. This paper discusses the design and construction components of the Highway 8 (Queenston Road) rehabilitation project. The project was completed on a 5.3 km section of east-west arterial road in a heavily trafficked urban environment. Partial-depth and full-depth reclamation of the existing pavement structure were selected to construct a recycled cold mix base course. Stabilization of the reclaimed material was achieved by adding expanded (foamed) asphalt binder and overlaying it with 50 mm of hot mix surface course. The impacts of cold recycling technology on traffic, adjacent residents and businesses, and overall budget implications are discussed and compared with conventional rehabilitation strategies. The City of Hamilton will continue to monitor the performance of the pavement to ensure that recycled cold mix base courses provide an acceptable rehabilitation strategy to deal with infrastructure renewal requirements in both an economical and sustainable fashion.
