PAVEMENT BINDERS AND ENERGY SAVINGS; A CONDENSED VERSION OF AN OECD REPORT

Possible savings in energy, oil products and costs through the use of alternatives to petroleum bitumen and portland cement are assessed. Alternative construction techniques which may lead to savings are also described. Materials considered for partial substitution of bitumen are: coal tar, rock impregnated with hydrocarbons, oil shales, natural asphalts, sulphur and lignin. Materials considered for total substitution are: coal tar, waste plastics and chemically modified sulphur. Developments in the use of various polymers to enhance the properties of bitumen and improve pavement durability or reduce bitumen quantity through a reduction in pavement thickness are reviewed. Energy savings accruing from the use of bitumen emulsions are estimated as are energy savings from pavement recycling. Developments in low-energy substitutes for portland cement concrete are described and the use of industrial by-products and natural materials having hydraulic or pozzolanic properties is reviewed. The effects, on the design thickness of bituminous wearing courses, of improving the properties of roadbases by treatment with hydraulic binders and the reduction in the energy content of pavements through the use of marginal aggregates are discussed.
