Design of Optimum Asphalt Dosage for Foam Asphalt Cold Recycling Mixture
Based on the laboratory test of foam asphalt cold recycling mixture,the determination method of the optimal asphalt content of foam asphalt recycling mixture is discussed.The optimal asphalt to aggregate ratio was determined through comprehensive perform-ance analysis using dry splitting strength,wet splitting strength,dry wet splitting strength ratio,Marshall stability,residual Marshall sta-bility in water immersion,and freeze-thaw splitting test strength ratio to obtain the optimal asphalt dosage.
