Composite Pavement.
A piece of new pavement of the composite kind, invented by Mr. H. F. Williams, of San Francisco, is now being tried m Cannon Street, London, opposite the Mansion House station of the Metropolitan District Bailway. The. pavement is laid on a concrete foundation faced with cement, which is set hard and dry before the superstructure is built. This consists of wooden blocks about 8 inches long by 4 inches deep by 1J inches wide, which are set on the foundation like bricks on edge, and with the end of the grain — that is, the lj-inch side— uppermost. Previous to being set thus each brick is dipped m a boiling mixture of Val de Travers asphalte and Trinidad bitumen. The bricks are then laid so as to break joint, and the interstices are filled m with boiling pitch. Lastly, over the bricks is spread a covering of asphalte half an inch thick, and mixed with coarse sand and grit. The grit prevents the asphalte from being greasy m wet weather.
