The April 2017 newsletter from the National Concrete Consortium, called NCC E-News, covers the following:
Moving Advancements into Practice (MAP) Brief: The April 2017 MAP Brief, Performance Engineered Concrete Pavement Mixtures, explains the process of designing concrete mixtures to provide the performance properties desired rather than just using a "recipe" mix.
NCC State Survey Summary:
- The Minnesota Department of Transportation polled the NCC group regarding the use of keyways when tying multiple lanes together.
- The Virginia Department of Transportation recently constructed several bridges with lightweight concrete (LWC) to examine its potential benefits for reducing bridge deck cracking.
- Researchers at Texas A&M University investigated the use of the bi-material semi-circular bend (BSCB) test method to evaluate the bond strength between portland cement concrete and asphalt at different temperatures.
- The Virginia Department of Transportation investigated the properties and potential benefits of roller-compacted concrete.
- A paper published in the December 2016 ASCE Journal of Performance of Constructed Facilities compared the performance of injected polyurethane foam and cementitious grout for stabilizing deteriorating concrete pavements supported on an open-graded aggregate subbase.
