Cores were pulled and the thicknesses of the HMA and the overlays are given in the through along with the shear strength at the interface, which was measured using the Iowa shear test. No visible distresses have been observed after five to six years of service. 22: Layer properties for the project at MO-5, railroad crossing in Lebanon.
