RENEWAL OF OLD STREET-PAVEMENTS.
SJEECIZFIGA'EIQN forming part of Letters Patent No. 727,512, dated May 5, 1903.
Application filed April 14. 1902. Serial No. 102,758. (No specimens.)
T0 at whom, it may concern:
Be itkn own that I, FREDERICK J. \VARREN, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a new and usefullmprovement in the Renewal of Old Street- Pavements, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.
This invention relates to the following-described pavement and method of making it.
Itis a well-known fact that pavements made of stone blocks and of bricks are worn by traffic to such an extent as to become practically worthless, and no successful means, so far as I am aware, has been employed for continuing the use of so much of said pavements as is left, whereby the material may still serve to form a part of a roadway. My invention is intended to accomplish this result; and it consists in breaking up such a wornout hrickror stone-block pavement into fragments-oymeans of a heavy spiked roller run over the same and causing it to be sufficiently split and broken up to leave a rough, cellular, but otherwise firm foundation to which a wearing-section of bituminous macadam may be applied and to which it will readily unite.
I am aware that a bituminous composition has been applied to the surface of said wornout pavements without previously breaking up the wornout pavement into fragments; but the said pavement is thenin so smooth a condition that the bituminous composition will notproperly unite with it. My invention does away with these smooth surfaces and provides a cellular structure having clean rough fractures which readily combine with the bituminous mixture applied to them and so as to make a homogeneous and solid union therewith.
I will now describe the invention in conjunction with the drawings forming a part of this specification, wherein Figure 1 is a view in vertical cross-section, illustrating a portion of a worn brick pavement before it has been resurfaced. Fig. 2 is a view of the same, representing the brick as broken up and prepared to receive the bituminous macadam repairing wearing-section. Fig. 3 is a vertical cross-section of a completed pavement.
Referring to the drawings, A, Fig. 1, represents the worn brick portion of a brick pavement. The worn bricks however they may have been disposed in originally forming the pavement are by my invention first reduced to a broken state and then compacted by heavy-pressure in order that a stable foundation for the reception of a repairing 0r,perhaps more accurately a new, wearing-section of a pavement may be provided. I prefer to break up the bricks by means of a heavy steam-roller armed with breakingspikes. The pavement is thus broken up to any desired extent, is then rolled by a heavy roller, (a heavy fifteen or twenty ton roller is preferred,) and is also surface-coated with a bituminous composition to form a binder course.
The rolling compacts the broken fragments and provides a uniform cellular surface for the reception of the bituminous binder,which may also be rolled, in. To this prepared foundation is then applied a wearing layer or sheet of bituminous macadam or other bituminous composition. The one which I prefer to useis that involving my inventions described in various Letters Patent of the United States and in applications therefor and which involves the use of selected mineral ingredients so proportioned and combined as to provide inherent stability without the employment of the bituminous composition and the use therewith of sufficient bituminous composition to fill the-voids and unite the mineral elements, the Whole being compacted under great pressure upon the foundation and laid, preferably, at about 200 Fahrenheit, whereby a dense, Weather and water proof stony bituminous wearing layer is provided. However, I do not confine myself in this invention to the use of a-wearing'-section of this composition, but may employ any other of the well-known types of bituminous composition.
While I have spoken ofthe invention as a means of repairing a worn-out brick or stone pavement and while it accomplishes this purpose, it really forms a new pavement and of a different character from the original. Its
value lies in treating an old pavement with out disturbing its subfoundation in a manner to convert it into a portion of a subfoundation, whereby it is transposed from its duty as a wearing-section to that of an intermediate supporting-section of a pavement.
While I have described the wearing layer applied to the broken original pavement as of a bituminous nature, I would say that a wearing layer of a macadam character may also be employed, as one of the essential fea tures of the invention is the use of the old pavement as a subcourse in a new pavement and when reduced to shape upon its original foundation by breaking and rolling to any desired or necessary extent, to thereby cheapen the cost of construction, use material otherwise worthless and save the cost of labor.
Havingthus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. The improved method of treating Worn brick or other pavements herein described,the same consisting in subjecting the worn brick or other equivalent surface first, to the action of breaking whereby it is broken into fragments or parts, second, to the action of rolling or compressing whereby the broken parts are solidified and leveled and then applying to said prepared intermediate foundation a wearing section or layer comprising a mineral base and a bituminous composition united together upon the prepared foundation under pressure whereby the mineral elements are bound together, the voids filled and the layer united to its foundation.
2. An improved method'for renewing street surfaces or pavements of Worn brick or stone, consisting in breaking While in place such brick or stone constituting such worn pavement and laying upon the broken material, a new surface of any kind.
3. An improved method for renewing street surfaces or pavements of worn brick or stone, consisting in crushing while in place such brick or stone constituting such Worn pavement, treating the surface thereof with a binder and laying thereupon a new surface of any kind.
4:. An improved method for renewing street surfaces or pavements of worn brick or stone, consisting in crushing while in place such brick or stone constituting such worn pavement, treating the surface thereof with a binder, compressing the binder into the crushed material and rolling the whole smooth, then applyingthereupon a surfacing material of any kind.
5. An improved method for renewing wornpavement surfaces consisting in crushingthe material of such worn surface while in place, and laying upon the crushed material a surfacing mixture of any kind.
6. An improved method for renewing wornpavement surfaces consisting in breaking the material of such worn surface while in place, thoroughly treating the broken material with an asphaltic or other binder, leveling the same and pressing thereupon a suitable surfacing mixture.
7. An improved method for renewing wornpavement surfaces consisting in thoroughly breaking the material of such worn surface while in place and so treating the broken material that a new wearing-surface is formed.
