<p>PRODUCTION OF HEATED BITUMINOUS MIXES A process for the production of heated aggregate mix, such as bituminous mix, and a reactor for carying out the process. In one aspect, the process entails the. control of gas flow through a tumbler drum, preferably by controlling exhaust from the drum, in dependence upon the continuous monitoring of a parameter, such as gas pressure within the drum. In a second aspect the aggregate contents of the drum are heated by using a burner to preheat the gas flow, a technique which permits admission of the drum feed as a homogenous stablized mix.</p> |
