The initial condition of the overlays was excellent from the standpoint of permeability, skid resistance, and bond, although some overlays were better than others. All were in good to excellent condition after one year in service, but the permeability had increased and the bond strength and skid resistance had decreased significantly. Based on the data collected during the first year it is projected that the overlays constructed with LB183 resin will have a useful service life of at least five years and that the MMA overlay will fail in less time
