WORKSHOP TOPIC 2. QUALITY STANDARDS

The possibility that energy considerations may lead to a reduction of quality in design, materials and construction standards is noted, and some of the points which emerged from the workshop discussions are listed. The adoption of more flexible specifications coupled with design alternatives should be more economical in terms of monetary and energy expenditures. The experience and initiative of the contractor must play a larger role in highway construciton. Several specific quality standards which show promise for reduction of energy requirements should be examined. Such standards relate to: the reduction of mixing temperature for asphalt mixtures; use of the drum dryer; aggregate blend that calls for the least volume of asphalt per unit of mixture; thickness design for full- depth asphalt pavement; use of plain concrete instead of reinforced concrete; the cosmetic aspects of the roadside.
