PERFORMANCE AND DURABILITY OF BITUMINOUS MATERIALS. 25: PERFORMANCE OF COLD RECYCLED BITUMINOUS MATERIAL

Cold-mix bituminous material used as an alternative to hot-mix bituminous products should lead to overall energy savings. If the granulate incorporated in such mixtures is of a secondary utilisation then further energy savings should accrue. The engineering equivalence and practical difficulties of using cold-mix formulations are not clearly defined. A full-scale trial has been constructed using cold recycled bituminous material as part of the rehabilitation of a relatively lightly trafficked rural road. The material was used as structural course in a haunch situation and extends over a length of one kilometre. A total bituminous construction method was adopted with the bituminous materials placed directly upon the subgrade soil. The environmental aspects of placement and early life performance of the cold-mix formulation are discussed. Relative structural characteristics of the materials are described together with a transient deflection performance study over a one year service life in order to yield an indication of structural equivalence.
