Adding macrotexture, or grooves, to pavements improves traction by helping water drain from roadways. However, as the macrotexture changes over time it can become less effective, so measuring and monitoring macrotexture is critical.
While the Florida Department of Transportation has successfully used point-laser systems to assess the macrotexture of the state’s asphalt pavements, the strategy has not produced as reliable results for concrete. To improve the accuracy of measures taken for both types of pavements, researchers tested line-laser systems in the lab the and the field.
