- Curing condition is one of the most important parts in the mix design of cold recycling mixture with foamed asphalt. A reasonable choice of curing condition can improve the consistency between the indoor mixture proportion design and the construction. The effects of different curing conditions on mechanical property of cold recycling mixture with foamed asphalt were studied by conducting the indirect tensile strength test (ITS) and optimum moisture content test. The influence of curing conditions on the strength of cold recycling mixture with foamed asphalt mixture was revealed. The results showed that when specimens were placed into an air-circulating oven at 60 for 40h, the rates of moisture loss and strength growth in cold recycling mixture were rapidly. So, the curing age of mixture did not have to be extended after the curing for 3d. When specimens wrapped in the plastic bags with sealing were placed into an air-circulating oven at 40 and curing for 48h, the rates of moisture loss and strength growth of recycling mixture were slowly and the hydration reaction of cement could accomplish adequately, promoting the sufficient formation of the strength. The cold recycling mixture with foamed asphalt in cement stabilized base had a greater strength and moisture content under the sealed curing condition at 40 . It can provide theoretical basis for guiding the construction.
