Study of viscosity-graded asphalt cements

Welborn, J.Y. / Oglio, E.R. / Zenewitz, J.A.

Laboratory study of asphalt cements representing broad range of sources that were collected by Bureau of Public Roads to investigate feasibility of grading and specifying asphalts by viscosity at 140 F in lieu of penetration at 77 F; among other findings, results indicate that when asphalt is graded by viscosity at 140 F resultant materials will have more uniform within-grade consistency at temperatures of 140 F and higher than materials obtained by use of present system of grading asphalts by penetration at 77 F.
