(under subclass 17) Pavement structure comprising (a) blocks, slabs or precast monoliths - not fabricated in situ on the road - united with, or by, (b) an in situ-formed surface layer.
SEE OR SEARCH THIS CLASS, SUBCLASS:
29, for pavement bed having a layer of blocks.
34+, for pavement structure made up of preformed modules. Many such preformed modular pavements include in situ material cast between modules. However, this may be distinguished from subclass 18 of Class 404 by the absence of any in situ cast surfaces equal to, or larger than, the extent of the modules being joined or united.
