Abstract
Road pavement evenness is one of the basic parameters characterizing road quality. Evenness influences car wear, fuel consumption, transportation costs, emotional state and comfort of drivers and passengers, and many other parameters. Assessment of road pavement evenness, which is widely used all over the world, has a number of features that do not allow to correctly assess an evenness at bridges, viaducts and other structures. Moreover, particularities of laser scanners operation do not allow to compare the obtained data with data obtained with the help of three-meter straight-edge. The paper suggests ways to solve problems in question, which enable significantly improving quality of evenness assessment at such important transport infrastructure objects as bridges, overpasses and viaducts. There is also a solution to compare the data of transverse evenness obtained by laser scanners with data obtained with the help of a three-meter straight-edge that will permit to use these data later for comparison with standard values.
