GREEN COUNTY, IOWA, CONCRETE OVERLAY RESEARCH PROJECT

The 42 different test sections of the Greene County Overlay Project will provide information on the following aspects of concrete pavement overlays: slab thickness, cement content, steel fiber content, joint spacing, bonding characteristics, initial square yard costs, maintenance costs, service life of different test sections, and comparison of fibrous concrete, continuously reinforced concrete paving with elastic joints, mesh, and plain concrete overlays. The first objective, to determine the feasibility of batching, mixing, transporting, placing, finishing, and texturing of fibrous concrete with conventional central mix plants and slipform equipment has been achieved. Although many problems were encountered and solved, further improvements should be made in handling and mixing of fibrous concrete.
