THE APPLICATION OF ROLLER COMPACTED CONCRETE TO PAVEMENTS FOR HEAVY TRUCK ROUTES IN ONTARIO

Over the past decade, the trends in the transportation industry to higher wheel loads and newer 'super single' tires which improve fuel efficiency have contributed to rutting of flexible pavements on heavy truck routes, causing increasing concern for both user safety and highway serviceability. As a result of the concern for the problems associated with the rutting of flexible pavements and the improved cost-effectiveness reported of newer rigid pavement designs, the Ontario Ministry of Transportation has renewed their interest in the use of Portland cement concrete for paving applications. This report contains a brief state-of-the-art review of roller compacted concrete (RCC). It is not slipformed as conventional concrete pavement, but compacted by rollers similar to the construction of bituminous pavements. RCC has a low moisture content and a low water/cement ratio, beneficial for the strength of concrete. The findings of an experimental program on the durability and fatigue properties of RCC are presented. In these laboratory tests, it was found that there is a larger than usual scattering of fatigue strength which has to be taken into account when determining design thickness. In summary, RCC can compete with conventional concrete; however, the cost savings are much less than usually suggested in the literature due to the fact that RCC pavements must be 10 to 20% thicker than conventional ones.
