Résumé dans la langue de publication The invention provides a concrete composition used in an overlay method of construction which is used for improving a deteriorated paved surface and/or a paved layer, the concrete composition comprising a cement, a shrink-reducing agent, an expanding agent, a high performance AE water-reducing agent and an AE agent, wherein the cement is a normal portland cement and/or a low heat portland cement. The concrete composition used in an overlay method of construction is rich in the bonding strength between an existent paved layer and a new surface layer and is resistant to exfoliation, cracking of a new surface layer and wear.
