The Marshall Mix Design method was originally developed by Bruce Marshall of the Mississippi Highway Department in 1939. The main idea of the Marshall Mix Design method involves the selection of the asphalt binder content with a suitable density which sat

In 1907, Fuller proposed the formula for maximum density gradation: P i = 100 (d i /D) 0.45, where P i = % passing sieve size d i, and D = maximum size of aggregate. In the 1960s, the Federal Highway Administration (FHWA) came up with the ‘0.45 power’ gra

equation of an “ideal” Fuller’s curve is: YT i = T X i - X 0 = T( X i − X 0)0.5 here T - is the coefficient, dependent on the maximum size of aggregate. It must be mentioned, that Fuller’s curve degree can be modified depending on type of used aggregate (

Defined by the Asphalt Institute (2001 [2]) as the fraction of fine aggregate that passes the No. 200 (0.075 mm) sieve. Restricted zone. A term associated with Superpave mix design that referred to a defined zone on the FHWA’s 0.45 power gradation graph.
