Abstract:

The special design of the transition layer between subgrade and semi-rigid base was scarce in the design system of pavement. The mechanism of the transition layer was studied, and then based on the analyses of reinforcing effect of transition layer under different modulus and thickness, the reinforcement incremental coefficient and optimal reinforcement model were proposed. Meanwhile, combined with typical semi-rigid base pavement structure, the economic modulus and thickness of transition layer were put forward. Results showed that the reinforcing effect was promoted as the increasement of the modulus and thickness of the transition layer, but the reinforcing efficiency was reduced. In order for higher reinforcing efficiency, the modulus of the transition layer should be 200~500 MPa, and the thickness should be not less than 20 cm.

Key words: the transition layer, structural design, reinforcement incremental coefficient, optimal reinforcement model, economic modulus
