As these forms are laid in place the base of thetriangle is adjacent to the rail and the hypotenuse the grouted stone is rolled these forms are pressedinto the structure, forming a flangeway in the are removed after the rolling has been completed. A group of men follow along after the rolling iscompleted and tamp down any irregularities in the sur-face and trim up the flangeway. These men are fol-lowed by another group equipped with brooms who dis-. Texture of Detroit Compressed Concrete Paving and Founda-tion Concrete as Revealed bt Test Opening tribute any surplus grout and complete the paving sur-face with a cross-brushed finish. This type of pavingis called compressed concrete paving in Detroit, butthe more common name for it is stone paving. It isbeing used quite commonly in highway construction andhas been used to a limited extent by New England trac-tion companies. The amount of stone used with thiscompressed process is from 8 to 10 per cent more than in ordinary concrete. The advantages claimed for thisparticular type of concrete pavement are as follows: Itis more dense and homogeneous than ordinary mixedconcrete. It is free from pockets of sand and fine aggre-gate. As the stone is placed and then grouted, large-sized stone can be used so that all wear is directly on thestone instead of on the cement mortar and the pave-ment thus has greater resistance to abrasion, the mor-tar cementing the stone together.
