Mix it Up

Recent study examines VDOT’s revised grading specs for the design of SMA mixes with smaller aggregates and the impact of aggregate morphology on the structural stability of the mix.

Recent advances in laboratory polishing and friction testing now provide a better assessment of friction that considers the entire gradation in an asphalt mixture rather than a single aggregate source.

Blacklidge Emulsions looked at volumetrics and performance of plant-produced mixes with increasing RAP content and its rejuvenating product, ReGen.

FDOT uses StellarFlex FR asphalt binder and Evotherm M-1 warm mix asphalt technology to combat pavement issues presented by horse-drawn carriage traffic.

Hawaii Asphalt Pavement Association Executive Director Jon Young explains components of a job mix formula for dense-graded mixes–a must read introduction to JMFs.

Rosphalt 50 design means extra delivery, paving, compaction considerations on Tappan Zee Bridge

The automated asphalt extraction is an innovative, efficient, quick and safe solvent-based extraction of asphalt binder from asphalt mixtures, to characterize and control the quality of asphalt mixtures by measuring asphalt content and studying the aggregate gradations. This method is used for quality control and assurance, acceptance criteria, and research activities. The PaveAnalyzer is designed […]
