CONSTRUCTION AND PERFORMANCE OF COLD MIX PLACED BY THE MIDLAND MIX PAVER

Cold mixed, cold laid paving using the Midland Mix-Paver was introduced to the Province of Ontario in the summer of 1975 when several municipal roads were paved on an experimental basis. The experimental sections, and promotion of the process by the emulsion manufacturers generated considerable interest in the municipalities and work was scheduled for the 1976 construction season. The interest shown by the municipalities prompted the Ministry of Transportation and Communications to undertake an investigation of the machine and the product. Cold mix paving was promoted to realize the following benefits: 1) Lower cost with equivalent performance to hot mix paving on rural and suburban roads. 2) Flexible pavement. 3) Structural and geometric upgrading. 4) Low maintenance costs. 5) Use of locally available aggregates. 6) Combined mixing and laying allows consistent proportioning of aggregate and bitumen. This report is presented in two sections. Phase 1 documents observations made and experience gained while monitoring the work done by the Midland Mix-Paver in 1976. Phase 2 of this report consists of performance studies of the condition of roads built during the 1976 season and presents some observations and conclusions based on the present pavement condition.
