DEVELOPING IN ASPHALT ENGINEERING

The author describes asphalt batch mix and drum mixing plants and discusses the various merits of each, with emphasis on their use with recycled or reclaimed asphalt pavements. Development of asphalt plants has leaned toward: 1, production of more accurate mixes; 2, relatively lower production costs, with the capability of using the same plants for mixing asphalt and portland cement concrete; 3, the best adaptation of equipment to the worst working conditions (e.g., in the desert) as well as a more comfortable and hygienic environment; 4, relatively easy and quick transportation and erection. He discusses cleaning of road surfaces, spraying bituminous binders, and placing and compacting hot-mix, with special attention to available equipment. Finally, he discusses the training of the work force, especially in developing countries where the lack of trained staff can hamper the initiative of the government. (IRF)
