THIN FILM PAVEMENT ASPHALT MIXTURE, METHOD OF REPAIRING PAVED ROAD, AND PAVED ROAD
To provide a thin film pavement asphalt mixture capable of supplying a large volume inexpensively and improving durability, a method of repairing a paved road using the same, and the paved road repaired thereby.SOLUTION: A thin film pavement asphalt mixture 1 is obtained by heat mixing a bone material and asphalt, the bone material has a maximum particle diameter of less than 8 mm, and in a particle distribution of the bone material, a rough bone material having a particle diameter of 2.36 mm or more and less than 8 mm is within the range of 65 mass% or more and 80 mass% or less, a fine bone material having a particle diameter of 0.3 mm or more and less than 1 mm is within the range of 5 mass% or more and 25 mass% or less, and a total of fine sand having a particle diameter of 0.075 mm or more and less than 0.3 mm and stone powder having a particle diameter of less than 0.075 mm is within 5 mass% or more and 25 mass% or less.SELECTED DRAWING: Figure 1
【課題】安価で大量供給が可能であり、かつ、耐久性を向上させることができる薄層舗装用アスファルト混合物、それを用いた舗装道路の補修方法、及び、それにより補修された舗装道路を提供する。【解決手段】薄層舗装用アスファルト混合物１は、骨材及びアスファルトを加熱混合して得られるものであって、骨材は、最大粒径が８ｍｍ未満であり、その粒度分布は、粒径２．３６ｍｍ以上８ｍｍ未満の粗骨材が６５質量％以上８０質量％以下の範囲内、粒径０．３ｍｍ以上１ｍｍ未満の細骨材が５質量％以上２５質量％以下の範囲内、粒径０．０７５ｍｍ以上０．３ｍｍ未満の細砂及び粒径０．０７５ｍｍ未満の石粉の合計が５質量％以上２５質量％以下の範囲内のものである。【選択図】図１
