Fig. 1 shows a schematic side view of anapparatus 10 according to the invention comprising abitumen tank 20 andbitumen 21 to be heated up therein. The bitumen heating apparatus is in the known manner agas burner 22 to which gas is fed from agas bottle 23. Thehot bitumen 21 in liquefied form exits thebitumen tank 20 via adosing tube 24 located in its bottom portion. A shut-offvalve 25 and acontrol valve 26 are attached to thedosing tube 24. At the end of thedosing tube 24, there is anapplicator foot 27 wherein the bitumen is allowed to enter. The dosedbitumen 21 does not spread out in the lateral direction but remains inside theapplicator foot 27. When theapplicator foot 27 is moved along a joint or a crack the bitumen adequately fills up the joint or crack to be filled. - According to the invention, hot compressed air is used efficiently in the
apparatus 10 to help fill the joint or crack. The compressed air is conveyed from anair compressor 28 via acompressed air hose 34 into acompressed air tube 39 entering theapparatus 10. Theair compressor 28 can also be replaced by a fan when compressed air is not necessary. Thecompressed air tube 39 forms atube coil 29 under thebitumen tank 20, at thegas burner 22, which tube coil functions as a heat exchanger. While thebitumen 21 in thebitumen tank 20 is being heated by means of thegas burner 22 also the compressed air conveyed via thetube coil 29 becomes heated up. The hot compressed air is conveyed in thecompressed air tube 39 further on through thecasing 30 of the shut-offvalve 25 into thecasing 31 of thedosing tube 24. This ensures that thebitumen 21 entering theapplicator foot 27 via thedosing tube 24 remains sufficiently hot and liquefied form even if the filling of the joint or crack takes place in cold conditions. - An advantageous method is such that the hot compressed air is not allowed to be wasted but is rather conveyed from the
casing 31 of thedosing tube 24 to thenozzle 32 before the compressed air exits to the outside air. Thus the compressed air is directed via thenozzle 32 into the joint or crack to be filled to clean, dry and/or heat it up before dosing into it thebitumen 21 used as a filler. By cleaning, drying and/or heating the joint or crack beforehand, it is ensured that the concrete to be used for the fill will properly penetrate the joint or crack and also effectively adhere to itFig. 1 does not specifically show the shape of theapplicator foot 27 nor in which direction the filling operation proceeds in the figure. - According to the invention, hot compressed air is used for heating the dosing tube and the valves attached thereto and/or for cleaning, drying and/or heating the joint or crack to be filled prior to filling and dosing of hot bitumen into the joint or crack. Both methods can be used jointly, as shown in
Fig. 1 , or separately, as shown below inFig. 3 . -
Fig. 2 shows a schematic side view of an apparatus according to the invention wherein avehicle 33 serves as theapparatus 10 using hot compressed air in the filling of a joint or a crack. As seen inFig. 2 , abitumen tank 20 is located in the front portion of thevehicle 33, a wheel loader. Agas bottle 23 is located next to thebitumen tank 20 for the gas burner. Anair compressor 28 is located in the rear portion of the wheel loader, wherein it is attached to the hydraulic system of thevehicle 33. As the work machine has an integrated hydraulic system, it is advantageous to use attachments, such as theair compressor 28 in this case, by means of the hydraulic system. Apneumatic hose 34 has been conducted to the front part of the vehicle, in conjunction with thebitumen tank 20. -
Fig. 2 also shows that the operator of thevehicle 33 has good visibility to the joint or crack to be filled and to theapplicator foot 27dosing bitumen 21. InFig. 2 , theapplicator foot 27 is depicted so that it is in front of thevehicle 33 and thebitumen tank 20. In practice, however, it is advantageous to locate the dosing tube andapplicator foot 27 slightly to the side, whereby it is closer to the operator of thevehicle 33 and even better in his or her field of vision. Yet another excellent detail of the invention is that the operator of thevehicle 33 has a control apparatus in the cabin, by means of which he or she can adjust the control valve of the dosing tube. This makes the filling of the joint or crack very efficient.Fig. 2 shows acontrol cable 35 as an example of the control apparatus moving thelever 36 of the control valve. -
Fig. 3 shows a schematic side view of an apparatus according to the invention wherein hot compressed air is used to clean, dry and/or heat a joint or crack. The apparatus has acoil 29 of a compressed air tube located in a hand cart, which coil is heated by means of agas burner 22 located in the bottom portion of the apparatus and directed upwards. Hot exhaust gases are directed away from the user of the apparatus by means of atube 37. The hot heating compartment 38 can be guarded by mesh or a grille not shown inFig. 3 . The compressed air exits via anozzle 32 so that the hot blast of compressed air is directed into the joint or crack to be filled. - It is obvious to a person skilled in the art that the different embodiments of the invention may vary within the scope of the claims presented below.
