Every asphalt structure layer's modulus was calculated by deflection survey with point to point.Based on structure layer modulus the material composition design requirements for cold recycled mixtures was put forward through finite element analysis of cement and emulsified asphalt cold recycled upper base.According to these requirements the material composition design of cold recycled mixtures was made and the test roads were built for verification.The results indicate that life and performance of asphalt pavement is improved by the maintenance of the cold recycled mixtures which was designed by the method.
