Abstract:

Even before a newly placed concrete pavement has achieved its specified design strength, it is often subjected to loading from construction traffic and equipment. Concrete trucks, haul trucks, and joint-sawing equipment are among several of the different types of construction traffic to which a young pavement may be subjected. Engineers have long speculated whether this early loading of the young pavement by construction traffic causes any significant damage to the pavement. In a research study for the Federal Highway Administration, the effects of early loading of a young pavement by construction traffic at different locations were investigated. Accumulated fatigue damage inflicted by an 18-kip single axle was calculated for the edge, interior, and transverse joint loading conditions for a slab of various concrete strengths. The results indicated that slab edge loadings were the most critical and, depending on their magnitude and the strength of the concrete at the time of loading, could reduce the life of the pavement. The interior and transverse joint stresses were comparable in magnitude, but much less than those produced at the slab edge. Joint-sawing equipment was shown to have a negligible effect on the fatigue life of the slab.
