    摘要: A highway pavement of concrete slab-on-grade surface includes a prestressed portland cement concrete surface layer which is mounted on a non-freezing low restraint support grade layer without any linear physical connection thereto in such a manner as to permit freedom of movement toward the midpoint of the surface layer. The surface layer is thereby able to slide in response to temperature and moisture changes in the environment including at temperatures below the freezing point of water. The surface layer has a riding surface of generally the same rideability five years after installation as it does at the time of installation.
