Abstract

7796. Hooley, E. P. April 3. Asphalt paving. -Relates to the "tarring" of broken slag, macadam, &c. for road - making purposes, foundations, tar concrete, &c. The coating-.material consists of tar, pitch, Portland cement, and resin. The tar is placed in the mixer a and is gradually heated by means of the steam coil a<1> to a temperature of about 212‹ F. The other ingredients are added, and are thoroughly incorporated with the tar by means of the mixing- arms a<2>. The coating-mixture passes to the reservoir c, also steam-heated, and is supplied in graduated quantity by means of a valve d' to a trough e from which the supply pipes e<1> proceed. The stone &c., broken in the crusher f, is gauged by a revolving screen f and passes down vibrating shoots f<2> to the steam-jacketed mixing-chambers g, which can be adjusted to any desired inclination. Helical blades g<3> mix and convey the materials, which are discharged at g<6>. Surplus coating-material drains off through the grating g<4> and is discharged at g<5>. Slag, broken while hot from the blast furnace, is preferably employed in the manufacture of the material, drying being thus rendered unnecessary.
