Design Theory for Used Road Cover and Evaluation of It at Home and Abroad

At present, a lot of used roads in our country have neared or exceeded their periods of design, and facing with overhall and intermediate maintenance. However, the covers of used road are all the time focal points studied in road engineering realm at home and abroad, and so are difficult points. The paper overall sums up design theory and procedures for road covers at home and abroad, and respectively estimates them, which gives an inspiration to transformation and design of used road in our country.
