How to Build Smooth Concrete Roads and Measure Success the Moment You Pave

The Strategic Highway Research Program 2 (SHRP 2) recently completed a study entitled, “Real-Time Smoothness Measurements on Portland Cement Concrete Pavements during Construction”. As part of this project, the feasibility of this technology was explored. There was both an evaluation and demonstration of emerging and proven technologies. Model specifications and construction guidance were also developed to construct smoother concrete pavements and expedite the implementation of these innovative technologies. Seven potential measurement devices were identified and studied, with two of them warranting subsequent evaluation and demonstration. Concrete paving projects throughout the USA including the States of Georgia, Alabama, Texas, Michigan, and New York were visited, and observations made about the potential of these devices. The resulting guidance has proven beneficial in improving the quality of pavement construction through improved smoothness (evenness).
