Pavement-Related Technologies
Aggregate Imaging System (AIMS)
The composition of aggregates used in pavement surfaces affects durability and skid resistance. The Aggregate Imaging System combines hardware that captures real-time digital images of paving material samples, and software that analyzes shape, texture and ratio characteristics of aggregates such as Hot Mix asphalt and hydraulic cement concrete, to improve the speed and accuracy of testing. Award amount: $200,000.

Asphalt Binder Cracking Device
The way asphalt responds to low temperatures is critical to its performance. The Asphalt Binder Cracking Device provides a simple and reliable method to test the cracking potential at different temperatures of the binders used in asphalt. The device will assist the industry in predicting and preventing asphalt failure due to cracking at low temperatures, extending the life of pavements and reducing the need for patching or repaving. Award amount: $225,061.

Intelligent Asphalt Compaction Analyzer
Improper compaction during construction is a leading cause of asphalt pavement degradation. The prototype Intelligent Asphalt Compaction analyzer is a device mounted to compaction equipment to provide real-time data so compaction inconsistencies can be remedied while asphalt is still pliable. Replacing the time-consuming manual process currently used will reduce construction time and make pavements last longer. Award amount: $200,000.
