PAVEMENT MATERIAL WITH HIGH HEAT DISSIPATION
To provide a pavement material with high heat dissipation capable of more effectively lowering the surface temperature of a pavement body than before.SOLUTION: A pavement material consists of: an aggregate including porous slag particles, silica rock, and alumina particles; cement; and an admixture. The content ratio of the alumina particles and the silica rock in the total amount of the silica rock and the alumina particles contained in the aggregate is 10 to 50 mass%. The total amount of the silica rock and the alumina particles contained in the pavement material is preferably 5 to 25 mass% of the pavement material. The alumina particles may have one type of particle size distribution range. Alternatively, two types of alumina particles having different particle size distribution ranges can be mixed.SELECTED DRAWING: Figure 1
【課題】従来よりも舗装体の表面温度を効果的に低下させる、高放熱性の舗装材を提供すること。【解決手段】多孔質スラグ粒子、珪石及びアルミナ粒子を含む骨材と、セメントと、混和剤とを含み、前記骨材に含有される前記珪石及び前記アルミナ粒子の総量における前記アルミナ粒子と前記珪石との含有比率が１０〜５０質量％である、舗装材である。前記舗装材に含有される前記珪石及び前記アルミナ粒子の総量は、前記舗装材における５〜２５質量％であることが好ましい。前記アルミナ粒子は、１種の粒度分布範囲を配合することができる。あるいは、異なる粒度分布範囲を有する２種のアルミナ粒子が混合することができる。【選択図】図１
