This paper was presented as the principal address, Session 1. This paper discusses current research activities associated with the conservation of energy and scarce materials for construction and maintenance operations being undertaken by the Federal Highway Administration in the United States of America. The need for this research arises from the projected demand for crude oil by the year 2000, which is expected to outstrip supplies available from conventional sources, plus the prediction that public concern and support for more emphasis on energy conservation measures in the transportation field will increase as the economic law of supply and demand forces energy costs upward. Whilst the major component of energy use is vehicle propulsion, a significant amount must be available for construction and maintenance operations. Energy conservation measures discussed include the development of binder materials for paving mixtures, greater utilisation of waste and marginal materials, and the recycling of existing highway surfacing materials. Particular subjects discussed in detail include the possible use of sulphur as a binder material, cold and hot recycling procedures, and the need for interim energy conservation measures, given that, at present, it is not economically feasible to produce large quantities of energy from alternate unlimited sources (A).
