本発明はアスファルトコンクリート路面を補修するに際
して行なう路面加熱方法およびその装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for heating a road surface when repairing an asphalt concrete road surface.
従来、アスファルトコンクリート路面を補Ｉｉするには
、加熱装置により路面を予め、加熱して軟化させ、その
後に路面を掻きほぐし装置で掻トはぐし、ついで転圧作
業等を行なうものである。Conventionally, in order to repair an asphalt concrete road surface, the road surface is heated in advance to soften it using a heating device, and then the road surface is scraped off using a scraping device, and then compaction work or the like is performed.
しかしながら、前記加熱方法では、路面の深部まで十分
に加熱されず、しかも掻トはぐされたアスファルトコン
クリートは直ちに冷却されて、後工程の転圧時には温度
不足になるという欠点を有していた。However, the heating method described above has the disadvantage that the deep part of the road surface is not sufficiently heated, and the scraped asphalt concrete is immediately cooled, resulting in insufficient temperature during rolling compaction in the subsequent process.
これを解決するためには、路面を十分加熱する必要があ
り、補修作業が遅くなるという別の欠点を生じていた。In order to solve this problem, it is necessary to sufficiently heat the road surface, which causes another drawback of slowing down repair work.
本発明は前記従来の欠点を除去するためになされたもの

方法およびその装置を提供することを目的とする。The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional methods. It is an object of the present invention to provide a road surface heating method and apparatus for quickly repairing a road surface by applying the amount of heat necessary for the process.
つぎに、本発明を図面にしたがって説明する。Next, the present invention will be explained according to the drawings.
図面は、本発明にかかる熱風吹き付は式路面加熱装置で
、大略、熱風発生装置１と、熱風ダクト４と、掻きほぐ
し装置５とからなる。The drawing shows a hot air blowing type road surface heating device according to the present invention, which roughly consists of a hot air generator 1, a hot air duct 4, and a loosening device 5.
前記熱風発生装置１は、その先端部に設げた熱風ダクト
４の温度を検知して、バーナ２の燃焼量を制御して熱風
温度を所定温度とする温度制９１１装置３とからなる。The hot air generator 1 includes a temperature controller 911 device 3 that detects the temperature of a hot air duct 4 provided at its tip and controls the combustion amount of the burner 2 to maintain the hot air temperature at a predetermined temperature.
そして、前記熱風ダクト４の先端部にはカバー６およ１
公知の掻ぎほぐしく幾であるロータリスカリファイヤ７
とからなる掻きほぐし装置５が設けである。A cover 6 and a cover 1 are provided at the tip of the hot air duct 4.
Rotary scarifier 7 with a known scraping pattern
A loosening device 5 is provided.
また、前記熱風ダクト４には、カバー６の上部に開口す

れている。The hot air duct 4 also includes a nozzle 8 that opens at the top of the cover 6, and spray 7 nozzles 9, 10 that heat the scraping position of the scraping rock 7 and the asphalt concrete H, 1 after scraping. has. The road surface heating device having the above structure is attached to a tow vehicle or the like (not shown).
なお、前記実施例では掻きほぐし槻としてロータリスカ
リファイヤを示したが、これに限らないことは勿論であ
る。In addition, although the rotary scarifier was shown as a scraper in the said Example, it is needless to say that it is not limited to this.
前記構成からなる路面加熱装置を使用するには、まず、
バーナ２を燃焼させ燃焼ガス温度を所定温せればよい。In order to use the road surface heating device having the above configuration, first,
It is sufficient if the burner 2 is combusted to bring the combustion gas temperature to a predetermined temperature.

用してもよい。That is, the hot air blown into the cover 6 from the seventh nozzle 8 also heats the front of the scraper 7, and then the asphalt concrete 11 softened by the heating is scraped and loosened by the rock 7. Then, the loosened asphalt concrete 11 is heated by hot air from the nozzles 9 and 10 during subsequent spraying. Since the asphalt concrete 11 has been loosened, the heating by this nozzle 9 and 10 has a large heat transfer area and sufficiently raises the temperature, and the asphalt concrete 11 is compacted by the following tractor in a softened state. . In addition, the hot air temperature in the hot air duct 4 is
Approximately 250 to 300 to prevent asphalt deterioration
°C is appropriate. Further, depending on the temperature and the condition of the asphalt concrete 11, any one or two nozzles may be used without using all the nozzles 8,9,10.

面を補修でき省エネルギー。As is clear from the above explanation, according to the method of the present invention, since the asphalt concrete is loosened and then heated, the heat transfer area is large, and post-processes such as compaction can be carried out in a sufficiently softened state. In the conventional method, the repair speed in summer [υj] was 1.0+n/Ill In, but it can be increased to 2.7io/+nin. In addition, even in winter, by installing a simple preheater in front of the reed, the road surface can be repaired at a rate of 1.5 m/min, saving energy.
省力化を図ることができるものである。This can save labor.
