  The present invention relates to an on-vehicle asphalt mixture heating and stirring apparatus.

  Asphalt mixture used for repair work of asphalt paved roads may be purchased and used at an asphalt plant, or may be used by premixed material heated and stirred on site. .

  In the former case, there is a merit that repair work can be performed immediately after arriving at the repair work site, but the temperature of the asphalt mixture decreases during the transfer (transportation) from the asphalt plant to the repair work site. There is a demerit that causes deterioration.

  Therefore, in order to prevent the temperature of the asphalt mixture from lowering, it is necessary to heat or keep the asphalt mixture during the movement, but the conventional asphalt mixture heating device is generally of the gas combustion heating type and is being moved. Since the gas combustion is dangerous, it cannot be used. Therefore, conventionally, the temperature of the asphalt mixture is prevented by covering the asphalt mixture with a heat insulating sheet or the like.

  However, this thermal insulation sheet is not enough to prevent the temperature drop, and during low temperatures such as in winter, quality deterioration occurs over time, making it impossible to carry out repair work smoothly or to finish the repair area cleanly. In some cases, it may become impossible.

  In the latter case, this temperature reduction problem does not occur, but since it is created (manufactured) after arriving at the site, it takes time to create it. It has become.

  In addition, as described above, the heating and agitating device used when producing the asphalt mixture at this site employs gas combustion heating as the heating means. Therefore, heating by gas combustion is dangerous while the vehicle is moving. Therefore, when performing small-scale repair work at multiple locations on the same day, the asphalt mixture cannot be heated while moving between construction sites, so it is the same as that manufactured at an asphalt plant. In some cases, the temperature decreases with time, resulting in quality degradation.

  The present invention has been made in view of such a current situation, enables heating and stirring work during the movement of the asphalt mixture, can prevent the temperature of the moving asphalt mixture from decreasing, and further, the asphalt mixture can be used on site.
