Recent years have presented a real financial challenge for highway departments. The energy shortage and rapid inflation have resulted in a severe reduction in proposed programs. The result has been an increased emphasis on investigating alternative roadway sections and construction procedures. Many secondary roadway departments have utilized macadam base construction with varying degrees of success. Macadam base construction does appear to have a potential for providing the structural needs at a lower cost. The recent macadam base projects have provided excellent drainage characteristics but there is an apparent lack of stability. Even when the base is properly rolled and keyed together, the large stones are easily displaced. The use of an asphalt emulsion binder may increase stability-while still providing a relatively low cost roadway base and reduce energy consuming construction costs.
