RESEARCH CONCERNING THE RESISTANCE OF ROAD SURFACES MADE OF A POROUS ASPHALT MIXTURE INCLUDING COARSE AGGREGATE WITH A SMALL PARTICLE SIZE

小粒径粗骨材を混入したポーラスアスファルト混合物の路面抵抗に関する研究

The durability of pavement materials is greatly improving. For this reason, the service life of payment is going to become longer beyond comparison with the past. With long-life pavement, damage differing from that so far may be expected to occur. One such type of damage is polishing, i.e., the polishing of aggregate resulting in a decrease in resistance to slippage. Polishing will presumably appear most markedly in the case of porous pavement composed of much coarse aggregate. The authors therefore attempted to improve road surface texture by using macadam whose particles have a diameter of no more than 5 mm for the porous asphalt mixture, in order to assure a stable road surface resistance. As a result, they found that the related pavement could deliver a stable road surface resistance into the long term better than that made with the conventional porous asphalt mixture.　舗装材料の耐久性は大幅に向上され，今後，舗装の寿命は従来とは比較にならないほど長くなると予想される．このため，これまでとは異なった形態の損傷が生じることが予想される．その一つとしては，粗骨材がタイヤにより長期間すり磨きかれ，すべり抵抗が低下するポリッシングが考えられる．多くの粗骨材で構成されているポーラス系の舗装では，このポリッシングが顕著に表れると考えられる．<br>　このことから，長期間，安定した路面抵抗を確保するため，ポーラスアスファルト混合物(13)に7号砕石を混入させ路面テクスチャを改善することを試みた．新たに考案したすり磨き試験の結果，検討した混合物は，従来のポーラスアスファルト混合物より，長期間にわたる路面抵抗の確保が期待できることがわかった．
