History of Asphalt Mix Design in North America, Part 1: From Hubbard to Marshall

This article, the first in a two-part series, discusses the development of asphalt mix design technology, giving readers the background to better understand Superpave. The author goes back to 1890, to a series of articles on roads and paving, written by E.G. Love. Articles around the turn of the 20th century talk about surfacing mixtures and asphaltic concrete, the latter which is more reminiscient of current hot mix asphalt. The next major development occurred in the 1920s, when Charles Hubbard and Frederick Field developed a method of mix design called the Hubbard Field Method of Design. The Hubbard Field method selected asphalt content based on air voids (VMA) and stability. The author goes on to describe the work of Francis Hveem, a resident pavement engineer in California in the late 1920s. Hveem developed a stability test for pavement mixes, which this author deems a pseudo-triaxial test. The final section familiarizes readers with the Marshall mix design, developed in the early 1940s; the author also reviews the role of the Asphalt Institute in the 1950s and 60s.
