Arkansas Superpave® Seminars: Model Technology Transfer Partnership

Abstract

Arkansas implemented the Superpave® asphalt mixture design system in 1997 for all state and federal highways. Local roadway agencies in Arkansas, including cities and counties, have historically used Marshall method–based mixes—typically by specifying the use of state mix in paving projects. In recent years, however, more Superpave-based mixtures are being used for local projects, leading to an acute need for information at the local level about specification and construction practices necessary for Superpave. A partnership of people representing academia, industry, local roadway agencies, and the state highway agency was formed to develop and present information to local agencies and consulting engineers on the use of Superpave for low-volume roadways. The goal of the partnership was to develop a series of Superpave seminars to provide vital technology transfer to local roadway personnel. Nine seminars were held throughout Arkansas, drawing more than 250 people from cities, counties, consulting engineering firms, and other interested parties. The seminar series proved to be a success. Keys to the success included a buy-in of all major stakeholders in the partnership; a funding strategy for development and execution that allowed attendees to participate at no cost; an informal, hands-on presentation seminar approach; and recognition of the realities of local roadway agency practices and the need to frame new technology within those practices. Attendee feedback was overwhelmingly positive and indicated a willingness to participate in future technology transfer activities.
