UTA researcher to employ scanning laser to measure microtexture of aggregates in Texas pavement

Data-driven discoveryA University of Texas at Arlington engineer is working with the Texas A&M Transportation Institute to assess whether scanning lasers can accurately measure microtexture of aggregates, which are used in asphalt and concrete mixtures. Roger Walker, a professor of computer science and engineering , is leading the two-year, $671,011 project, which is funded through the Texas Department of Transportation. The agency currently uses camera-based systems to assess aggregate characteristics. “These lasers will enable TxDOT to more accurately measure
