Balanced Design of Asphalt Mixtures

Volumetric parameters form the basis for current state of practice in asphalt mixture design. Many state department of transportation (DOTs), including Minnesota Department of Transportation (MnDOT), utilize a design process that bases optimum binder content on volumetric principles. However, many DOTs across the nation are working towards implementation of balanced mix design procedures for hot-mix asphalt. Texas Department of Transportation (TxDOT) is one example of a state that is at an advanced stage of implementation. With volumetric design, assurance of good field performance requires confidence and engineering judgment, primarily based on experience. This project will be comprised of eight tasks focused on the development of a balanced mix design (BMD) approach for MnDOT. It is anticipated that the BMD will be developed primarily for use in designing surface course mixtures on medium to high volume roads. The research approach will consider climate, substrate and mix type in the design procedure. The project will begin with a review of technology and practice to define the activities other agencies will conduct in developing a balanced mix design procedure. Tests for low-temperature cracking, rutting and moisture sensitivity will be selected for the experimental portion of the study.
