本発明はアスフアルト舗装の継目部分の工法に
係るものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for constructing joints in asphalt pavement.
（従来の技術）
従来のアスフアルト舗装工法においては、既設
のアスフアルト舗装部の隣接部位に、アスフアル
ト混合物を敷均らし輾圧して、前記既設のアスフ
アルト舗装部に新設のアスフアルト舗装部を接続
し、以下このような工程を反覆して路面のアスフ
アルト舗装を行なつていた。(Prior art) In the conventional asphalt pavement construction method, an asphalt mixture is leveled and compressed in the area adjacent to the existing asphalt pavement, and a new asphalt pavement is connected to the existing asphalt pavement. The asphalt road surface was paved by repeating this process.
（発明が解決しようとする問題点）
前記従来のアスフアルト舗装工法においては、
既設のアスフアルト舗装部と新設のアスフアルト
舗装部との接合部の接着が悪く、同接合部の剥離
を生じ、特に冬期の施工においてはこの現象が顕
著に現われる。(Problems to be solved by the invention) In the conventional asphalt pavement method,
The bond between the existing asphalt pavement and the new asphalt pavement is poor, resulting in peeling of the joint, and this phenomenon is particularly noticeable during construction in winter.
この原因の大半は低温の既設のアスフアルト舗
装部の接合端面に、高温の新設のアスフアルト舗
装部のアスフアルト材料が接した場合、両者の温
度差が大きく、低温の既設アスフアルト舗装部の
接合端面に接触した高温の新設アスフアルト舗装
部のアスフアルト材料に急激な温度低下を招来
し、輾圧不足を生起し、接着性能が充分でないこ
とに基因低下する。 This is mostly due to the fact that when the asphalt material of a new asphalt pavement comes into contact with the joint end surface of an existing asphalt pavement section, which is at a low temperature, there is a large temperature difference between the two, and the joint end surface of the existing asphalt pavement section comes into contact with the joint end surface of a low temperature existing asphalt pavement section. This causes a sudden temperature drop in the asphalt material of the newly constructed asphalt pavement, which is at a high temperature, resulting in a lack of pressure, and the adhesive performance deteriorates due to insufficient adhesive performance.
