    • PROBLEM TO BE SOLVED: To provide a method and a device for easily refurbishing an existing asphalt pavement to obtain a pavement surface having water permeability or a water-retaining property.
      SOLUTION: The existing asphalt pavement surface is heated and softened by a heating means 2 like an infrared heater mounted to a heating work carriage 1. A drilling work carriage 3 is provided with a base plate 4a having a number of drilling pins 4b on its lower surface in a protruding manner, of which the base plate 4a is freely movable up and down. The drilling work carriage 3 follows the heating work carriage 1. The drilling work carriage 3 is moved to the heated and softened asphalt pavement surface, and the base plate 4a is moved down at the position so that the drilling pins 4b may enter into the asphalt pavement surface using vibrations of a vibrator. Thus, a number of small-diameter holes 5 reaching a predetermined depth in the asphalt pavement, or a number of small-diameter holes 5 penetrating the asphalt pavement to the ground and having water permeability are drilled.

    • 要解决的问题:提供一种用于容易地翻新现有沥青路面以获得具有透水性或保水性的路面的方法和装置。 解决方案:现有的沥青铺装表面通过加热装置2加热和软化,如加热装置1上安装的红外加热器。钻井工作托架3设有具有多个钻孔4b的基板4a 在其下表面以突出的方式,其中底板4a可上下自由地移动。 钻孔工具3跟随加热工作托架1.钻孔工作托架3移动到加热和软化的沥青路面,并且基板4a在该位置向下移动,使得钻孔销4b可以进入沥青 使用振动器振动的路面。 因此,在沥青路面中达到规定深度的多个小直径孔5,或者穿过沥青路面到地面并具有透水性的多个小直径孔5被钻孔。 版权所有(C)2007,JPO&INPIT
