ENERGY REQUIREMENTS FOR ROADWAY PAVEMENTS
There are four categories of energy requirements for highway pavements: basic paving materials--asphalt, portland cement, aggregates, etc; production of paving mixes--asphalt concrete, portland cement concrete, etc; transporting and stockpiling materials; and placing materials in the roadway and finishing the pavement. Energy is expressed in British Thermal Units (BTU) per unit item. There are a variety of fuels used in various operations, which consume varying amounts of energy. Those fuels include: gasoline; kerosene; fuel oils no. 1, no. 2 (Diesel fuel), no. 3, no. 4, no. 5, and no. 6; natural gas; propane gas; and butane gas. The per gallon consumption of BTU for each of those fuels is included. Since there are many factors and variables to consider when determining energy required to produce, mix, transport, and install highway paving materials, this paper contains an analysis of each operation or step along the way to determine the energy consumed to obtain a particular pavement.
