Study of the Behavior of Aggregates Demolition by the Proctor and CBR tests

The present study is a part of a large project on the valorisation of concrete demolition aggregates in order to contribute to their re-use in the field of the civil engineering, particularly in roads. After the recycled aggregates are sorted and selected, their characterization is based on the comparison of their physical and mechanical behaviors with the natural aggregates (sand and gravel). Then their responses under the Proctor and the CBR tests are studied before and after treatment with sand, cement and clay additions. However, the results obtained showed that the characteristics of the recycled aggregates are lower than those of the natural aggregates. The authors thought then to improve them by the additions quoted herebefore. The addition of these materials, allowed to appreciably ameliorate some of their physical and mechanical characteristics approaching those obtained for the natural aggregates.
