In recent years, very thin cement-concrete pavements (so-called Ultra-Thin Whitetopping or UTW) have increasingly been applied to asphalt pavements as a maintenance measure in case of surface damage in America, Sweden, France and other countries. The experience gained has been extremely positive and offers considerable potential for application. The technique has attracted attention partly as a result of the problems associated with the formation of ruts and corrugations with which large numbers of road maintenance authorities are faced at areas for stop lines at junctions and bus lanes. A thick topcoat is often not necessary because the damage is actually a surface problem and the road still retains sufficient load-bearing capacity. For the covering abstract see ITRD E135448.
