Relief for compression stresses in hot weather is provided at unsymmetrical intersections. This relief is in the form of expansion joints. Non-extruding compressible material is placed in the transverse joint so that the compressible material can relieve expansive forces. Preformed compressible material is installed in a dowel assembly at the location of the expansion joint. The expansion material shall extend down to the top of the subgrade and to the outside of the slab to allow free movement throughout the joint. The top of the expansion material shall be one inch below the surface of the finished pavement and this area sealed with an asphalt base liquid sealing compound.
