Description
AIJ APPARATUS FOR REPAIRING POTHOLES
FIELD OF THE INVENTION
Generally, potholes in roads are repaired by road gangs having little if any knowledge of the mechanics involved in efficiently repairing them so that they reform in the same place a short time later.
BACKGROUND OF THE INVENTION Briefly, a common method of repairing a pothole may be described as follows:-
(1) the pothole is inspected
(2) emulsion is squirted into the hole (this varies according to engineer policy and is not a standard procedure)
(3) bitumen mix is thrown by shovel into the hole and this is tamped down either with a friendly pat of the shovel or with a vibrator
(4) a thin coating of gravel dust is then thrown over the repair (this is optional also) .
The result of the above described operation is a very poor repair job that requires constant attention at regular time intervals.
DISCLOSURE OF THE INVENTION According to the present invention there is provided an apparatus, for repairing potholes in roads and arranged to be supported by a vehicle, comprising a reservoir for containing bitumen, a delivery means arranged to be connected to the reservoir and for delivering bitumen to a pothole, a cutting means for cutting potholes to a predetermined size, and a debris removing means for removing debris from potholes.

An outlet of the delivery means, the cutting means and an outlet of the debris removing means respectively are preferably connected together to form a head section.
Preferably, the control means is arranged to control operation of the head section.
The head section may be arranged to be placed over a pothole to be repaired and operated to perform a predetermined sequence of operations to repair the pothole. It is preferred that the head section be arranged to be connected with an arm which is operative to move the head section.
Preferably, the control means is arranged to control operation of the arm.
The apparatus may also be provided with an emulsion delivery apparatus for feeding emulsion to a pothole. An outlet of the emulsion delivery apparatus is preferably connected to the cutting means to form part of the head section.
It is preferred that the cutting means is located at the centre of the head section and the outlet of the delivery means and the compacting means are located on opposite sides of the cutting means.
It is additionally preferred that the the outlet of the emulsion delivery apparatus and the compacting means are arranged at the front and back of the cutting means.
Preferably, the head section is in the shape of a cross. The delivery means preferably comprises a pumping system.
The debris removing means preferably comprises a pneumatic suction system.
The cutting means preferably comprises a mill saw or diamond saw.
According to one embodiment of the present invention the apparatus is mounted on a trailer or a truck or tractor type vehicle.

The emulsion delivery apparatus preferably comprises an emulsion reservoir which is located adjacent the bitumen hopper.
The pneumatic suction system may be connected between the end part of the debris removal means and the air separator.
The arm is preferably hydraulically operated and is connected to the vehicle.
According to the present invention there is also provided a method of repairing potholes comprising the steps of providing a pothole repairing apparatus having a delivery means, a cutting means and debris removing means, operating the cutting means to cut a pothole to a predetermined shape and depth, operating the debris removing means to remove debris from the pothole, operating the delivery means to fill the pothole with a material such as bitumen and compacting the material with a compacting means. Preferably, the compacting means is part of the apparatus.
In a preferred embodiment an emulsion is delivered by an emulsion delivery means to the pothole before bituman is delivered thereto.
BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of the present invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows the apparatus in a side view when mounted on a truck,
Figure 2 shows a front view of the apparatus of Figure
1,
Figure 3 shows a bitumen hopper of the apparatus in an end view,
Figure 4 shows a schematic view of the head of the apparatus, and
Figure 5 shows a perspective view of the head of the apparatus.
The pothole repairing apparatus shown in Figure 1 comprises a bitumen mix hopper 13, a fine gravel hopper 14, a debris hopper 15 and an emulsion reservoir 16. The bitumen mix hopper, fine gravel hopper and debris hopper are formed as separate compartments in a large hopper located on the back of a truck 12.
The emulsion reservoir 16 is located on one side of the bitumen hopper 13.
The four reservoirs mentioned above are connected by means of pipe work, to an operating head 17 at the front of the vehicle and shown in detail in Figure 5.
Figure 1 and Figure 2, show three pipes extending from the operating head to the rear of the vehicle. One of these pipes 18 is connected with the bitumen mix hopper, while another of these pipes 19 is connected with the emulsion reservoir 16. The remaining pipe 20 is connected with the debris hopper 15 via pneumatic suction system 21 and air separator 22.
Referring to Figure 3, a screw or pump conveyor is shown at the bottom of the bitumen hopper 13. An air receiver 24, for the pneumatic suction system 21, is shown on the side of the bitumen hopper which is opposite to that on which the emulsion reservoir is located.
Referring to Figure 5, the operating head is shown having a cross shaped configuration 25 with a mill saw 26 located at its centre. To the left and right sides of the mill saw 26 are located the end 27 of the pipe 18 to the bitumen mix hopper and a tamper or roll 28. The suction outlet end 29 of the pipe 20 to the debris hopper is positioned in front of the mill saw 26 and the outlet 30 of the pipe 19 to the emulsion reservoir 16 is located at the back of the mill saw 26.
As shown in Figures 1 and 2, the operating head 17 is connected to the front of the truck 12 by means of an hydraulic arm 31.
The operation of the apparatus described above is outlined as follows.
First of all a pothole is approached, its position can be anywhere across the front of the vehicle and of any size. The operator of the vehicle then identifies the hole, stabilizes his vehicle and decides the best way to repair it to a standard size, either round, square or rectangular. A round hole shape is generally preferred.
Controls inside the truck are used to manoeuvre the operating head by operation of hydraulic arm 31, over the pothole, such that the mill saw 26 is located directly above it. Once in position the mill saw is operated to cut the pothole to the desired shape and depth.
The pneumatic suction pipe outlet 30 is indexed above the hole next and debris is removed by operating the pneumatic suction pipe to suck debris to the debris hopper 11.
The outlet 29 of the emulsion pipe is then indexed above the hole and emulsion is added.
Next the outlet 27 of the bitumen pipe is indexed over the hole and bitumen mix is pumped into the hole from the bitumen hopper 13.
The final step in the sequence is to index the tamper or roll 28 above the hole to press the bitumen mix.
A finish may be added to the repairing operation by pumping fine gravel from hopper 14 through the bitumen pump outlet if this is considered necessary.
The motion of the operating head during a repairing operation is shown in Figure 4 with each number shown in a circle indicating the order in which the various parts of the operating head are moved over the top of the pothole which is being repaired.
