Best Practices for Jointed Concrete Pavements / Blended Aggregates for Concrete Mixture Optimization Tech Brief General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Materials-Concrete

Description: Historically, aggregate gradation has been controlled by specifications that call out envelopes for individual fractions, typically the coarse aggregate and the fine aggregate. The shortcoming of this approach is that the gradation of the overall system is not addressed. While it is sensible to stockpile coarse and fine fractions separately to prevent segregation, it is the combined system that is critical in the final mixture.
