By using uniaxial penetration test,shearing strength of cold-recycled mixtures of foamed asphalt(CRMFA) under different conditions was determined.The test result shows that the shearing strength of CRMFA is the highest when the gradation of the mixture is in the specified range.With 1.5%(by mass) of cement,shearing strength of CRMFA is increased 5 times.The asphalt content corresponding to the highest shearing strength is dependent on the asphalt foam effect.The better the foam effect is,the less the asphal...
