The more care that is put into the quality, the better product we will receive with sound quality control and screening. Seceral advance have made recycling more economical for all types of concrete pavements. These includes:- · development of equipment for breaking concrete be they plain, mesh and doubly continous reinforced. · Develoment of methods to remove steel that minimizes the labour. Use and application of crushing equipments that can accomodate steel reinforcement.
