ASPHALT AND ENERGY INTERFACE: PROBLEMS AND SOLUTIONS

In an effort to conserve the energy involved in the crushing and hauling of aggregates to the job site, the use of asphaltic materials in the concept of full-depth asphalt pavement design and construction is recommended by the Asphalt Institute. This type of pavement is built in stages, and the depth width, and length can be increased as necessary. The pavement layers are bonded together so tightly that they are all integral parts of the structure. Fuel conservation concerns, scarcity of materials, and escalating costs combine to make the use of asphalt materials a very feasible method of pavement design for the future. In the meantime, measures such as the following should be taken to conserve energy with the present road system: Recycling, drum hot mix, emulsified asphalt, reduction of hot-mix temperatures, thick lifts, full-depth pavements, stage construction, asphalt overlays, and changes in contract and specifications practices. The media campaign of "The Road Information Program, Inc." to educate the public stresses: 1) construction of extra lanes to save fuel; 2) maintaining local roads as a result of changing driver habits; 3) the fact that vehicle miles will increase even if gasoline availability decreases; and 4) exclusive bus lanes are the best form of mass transit.
