As part of a project to study tire/road noise, a laboratory roadwheel facility was equipped with replica road surfaces. The replica surfaces, of a design first developed by Dunlop, Ltd., consisted of fiberglass and epoxy resin shells clamped to the roadwheel. The outer surface of each shell was molded from a rubber impression taken from a real road surface, thus replicating the texture. To evaluate the effect of pavement texture, and to establish the realism of the replica surfaces, a series of near-field measurements of noise from four heavy truck tires were made on the replica surfaces and on moving tests on the real surfaces. Moving tests on a flat steel surface were also made. Data from these same tires on a smooth steel roadwheel were available from a previous program.
