Application filed December 23, 1916. Serial No. 138,540.
To all whom it may concern:
Be it known that l[, JOHN HINEs, subject of the King ofGre at Britain, residing at 289 Finchley road, London, N. W., Engl v land, engineer, have invented certain new and useful Improvements in the Manufacture of Roads and like Surfaces, of which the following is a specification.
This invention comprises an improved to manufacture of roads and like surfaces. It
is well known to apply a flush carpet compounded of such materials as broken stone or slag with a bituminous binder and filling material upon' road surfaces to form a hard to bound durable dustless road surface. It is also well known to scarify a road surface'to some extent and to apply a bituminous binder and filler to grout. an existing road applying more metal until a desired depth to of treated material is obtained. This groutin or penetration method generally requlred proceeding in successive stages or layers to insure the requisite depth of penetration of the bitumen. These known at methods of manufacture can only be carried out successfully in fine dry warm weather as the material of the road and the applied materials must not be only quite free from moisture but must be heated to insure good W results, and as under. normal conditions such material after being once wet, retains the moisture for a long time, long delays occur entailing loss through-cost of labor etc. llt has been proposed with the object of avoid- 35 ing these delays to dry and heat portions of road surface by forcing heated air on to the same beneath a hood so as to prepare for the making or repairing operations.
The full benefits of this method have not hitherto been reaped owin to he subsequentexposure of the heate and ried surface for the carrying out of the later operations, and in this heated and dried state cold air and moisture if present are at once 3 absorbed, and the desired penetration of the bindin material and filler is not obtained.
Flus carpeting and grouting and like methods depend for their success upon the penetration of the binder into the existing W surface so that the new. andthe old marry together and any subsequentmovement of the one upon the other causing wave formation under rolling or trafiic is avoided.
My invention comprises an improved 5% manufacture in which the road is heated and dried by a current of air or hot gases in a suitable inclosure or hood and the heated binder and sand or other filler are delivered into the heated and dried road in the zone of heat or before exposure of the same to the atmosphere. The absorbent properties of theheated and dried surface during cooling are thus fully utilized to effect the desired penetration of'the binding materials.
The manufacture is preferably carried out by using ressure to force the heated binding material bitumen; asphalt, tar, etc., into the heated road and the filler is also preferably distributed by a current of air. or hot gases forming a hot blast.
A preferable form of apparatus for the purpose of carrying out the manufacture is set forth in my copending application, Serial Number 138,541, filed -Dec. 23, 1916' but any suitable apparatus in which the heated binder and filling materials may be distributed on the heated road surface within the inclosure or hood used for the heating operation or immediately behind same may be employed.
In the appended drawing which is asectional view of the preferred apparatus above referred to a is a suitable running frame, 6 a blower, 0 a suitable engine or motor, and (Z a furnace or air heater. The
, running frame may be adapted for propulsion or for trailing and any convenient arrangement for dr1v1ng the blower or fan may be followed. Adjacent to the furnace or air heater is a tank 6 for the'bitumen or like binding material with the main air or gas trunk f carried over or through the tank e and preferably along between that tank and a bin 9 for sand, or like other finely divided filling material. The air or gas trunk 7 passes along to the rear end of the tank 6 where an outlet pipe in is'provided leading to a hood j of conical or rectangular form. Preferably the hood is of square pyramidal form and the main enters at the vertex and preferably deflectors are ar-' ranged within the entrance to distribute the heated air or gas equally within the hoodr A by passage 70 for the air or gases may be arrangedleading around the tank with or part only of the gases may be sent around the tank. Any other arrangement of flues for circulating heat around the tank may be followed but preferably means will be provided in any case for insuring all the dampers e in the main. f so that the whole heat passing along the main trunk fwhen desired to the hood so as to insure sufficient for the purpose of drying and heating the road.
A pipe from the tank 6 leads to a spraying or distributing pipe Z which may if detion into the road. Any other means for forcing the liquid may be employed.
For the filler which may comprise sand, chippings, clinker dust, Portland cement, or the like, feeding screws such as n Fig. 4, or any other conveying means, may be employed in the bin 9 and the filler may be discharged into the outlet 72. and in the illustrated arrangement it enters a receptacle 0 on the hood j and is blown by the heated air or gas through the slot 0 into the hood near the liquid discharge. A deflecting valve Q} is shown for closing the normal entrance to the hood so as to deflect the filler and the current of heated air or gas into the receptacle 0, see Fig. 5. The screws n in the sand bin 9 may be driven from the road wheels or by hand or power as desired. The bottom of the receptacle '0' down which the sand, etc., will fall in its discharge may be curved transversely or provided with radiating ridges or grooves or any like means for facilitating even dis- I -tribution of finely divided materials may be employed. v A deflector 0 may be emwithin or outside the hood as devised.
It is desirable to provide fines or linings so that the heated air or gases may be utilized when desired entirely for heating the binding agent and the filler for example when the machine is not at work.
Beyond the hood j a second-sprayer pipe 8 Fig. 2 maybe carried by an extension t so that a second coat of the binder may be given to a treated surface as the hood is drawn forwardly for further operation.
It will be understood that the invention is not limited to the above construction which is given as an example only.
I claim:
1. The method of treating roadways and similar surfaces which consists in first heating and drying the surface to be treated by the use of a hot-blast, protecting the heated and dried surface from exposure to the atmosphere, then delivering upon such surface whileso protected a heated, plastic biniler, and finally allowing the surface to coo 2. In constructing roadways and the like by grouting, flush carpeting and similar operations, the method of treating the surface which consists of first heating and drying.
the same by the use of a confined hot-blast, protecting the heated and dried surface from exposure to the atmosphere, then delivering upon and into such surface while so protected a heated binder and filler, and finally allowing the surface to cool.
In testimony whereof I affix my signature.
JOHN HINES.
