Cold Asphalt Concrete Overlay
The report discusses the construction and first year's performance of two cold asphalt emulsion mixtures placed in a 1 inch overlay on an existing asphalt concrete pavement. This overlay is the first project in a study to determine if cold mixed asphalt concrete can reduce particulate and aerosol emissions and at the same time provide a durable asphalt concrete pavement. Details of mixing and placing as well as condition surveys of the pavement are discussed. Air pollution measurements and laboratory analysis of the mixtures are also discussed. The downwind dust from the plant was the same for cold mix as the hot mix operation. The particulate and aerosol emissions of the cold mix were less than hot mix operations. However, pavement performance has not been equivalent to adjacent hot mix pavement overlays. (Author)
