JOHN G. STAFFORD AND JAMES W. PHILLIPS, OF WASHINGTON, D. O.'
lMlROVEMENT IN CONCRETE PAVEMENTS.
Specification forming part of Letters Patent No. l 87,926, dated February 27, 1877; application filed January 19, 1877.
To all whom it may concern:
Be it known that we, JOHN G. STAFFORD and JAMES W. PHILLIPS, of Washington, in the`county of Washington and District ot' -Oolumbia, have invented a certain new and useful Improvement in Concrete Pavement, of which the following isa spectication, ret'- erence being had to the accompanying'drawing, which is a vertical section of our improved pavement.
The improved pavement consists, essentially, of a foundation of slabs and broken stone thoroughly bedded and packed. A base-course of broken stone, mixed with chemically-prepared bitumen, a binder-course of broken stone, heated and mixed with chemically-prepared bitumen, and a top or surface coat, consisting of clean sand, gravel, hydraulic cement, and a bituminous compound.
The invention further consists in the compositionof asphalt coal-tar, boiled at a high temperature, oil, oxide of iron, and brimstone, mixed with clean sand, gravel, and hydraulic cement, to form a top or surface coat of an asphalt or concrete pavement, as hereinafter described.
In carrying out our invention, we proceed as follows to lay'a ten to fteen inch pavement:
Foundation.
draulic or bituminous concrete, as preferred..
' Baraccano..
Third course: Any hard broken stone, from two to four inches in diameter, mixed with chemically-prepared bitumen, is spread evenly to the proper depth to suit the depth ot' pavement required, and thoroughly rolled with a steam-roller, or rammed with a steamlimestone or blue stone thirty pa y earth or white cla Eve parts; line hard cement ii E E l sand thirty parts; and Peekskill g avelz screened of the broken Astone into the interstices of the Y Binder-course.
Fourth course: Broken stone, from onehalf to one and one-half inches in diameter, free from dust, is heated to a little more than blood-heat, and then thoroughly mixed with chemically prepared bitumen, or coal tar boiled or distilled at a heat of 300, to which chemically-prepared bitumen, ten per cent. of the bitumen as prepared for the top coat, is added. It is then spread evenly over the street, and rolled and cross-rolled with a steam and stone roller to work the stone in place, and to consolidate the binder and base course.
Top or surface coat. i
Fifth course: A compound of ulverized rts; fullePs ve 1 r s; eau sharp angular through a half-inch screen, thlr y parts. After being' thoroughly mixed it is then heatedin rotary heaters; then mixed by suitabl'xf'hinery with the hereinafter-described bituminouscompound. It is then spread evenly over the binder-course, and rolled and cross-rolled first by hand, and then with steam and stone rollers, the composition being as follows: Three hundred and ninety-six pounds of' refined asphaltz two huded and follllr pounds of cliem ica y-prepare itumen t irty-six pouu s o a-a-r rammer, to work the points or sharp cornersoughly mixed in suitable kettles at a'proper temperature, according to the season, this mixture being mixed with chemically-prepared bitumen, in the required proportions to suit the climate and travel.
wenty pounds oxide of iron, fifteen pounds ot' rolled brimsttlTa-t'fof asphalt, boiled colei-gag, @b oxideofjron, and brnnstone, mixe 1n aboutthrtions `etter'im,end applied, together with clean sand, gravel, and hydraulic cement, to form a surface-coat, substantially as herein described and specified.
