Improved Resistance of Sulfur-asphalt Paving Formulations to Attack by Fuels.
I&ec Prod Res & Develop 1977 Mar; 16:1 pages
Sulfur-asphalt paving, in which sulfur replaces part of the asphalt binder normally present in conventional asphalt paving, was found by controlled laboratory tests to be superior to the conventional material in its resistance to the solvent action of gasoline, diesel, and jet fuels. Increasing the amount of sulfur in the formulations increased the resistance to attack by these fuels. Two test methods developed to simulate the solvent action caused by dripping or spillage of fuels onto pavements are described.
