Key Points

This research investigates how irregularities from broom finish impact the durability of concrete microtexture and the accuracy of slip resistance models.
Evaluated surface irregularities caused by broom finish on concrete pavements.
Assessed existing slip resistance estimation models.
Analyzed the contribution of roughness indices to wear resistance after abrasion.
Confirmed sufficient accuracy of updated slip resistance models.
Identified significant effects of roughness indices Ra(0.1) and Mr1(0.5).
Established that broom finish irregularities enhance the durability of microtexture after wear.

Abstract

コンクリート舗装のほうき目仕上げによる凹凸が，マイクロテクスチャの持続性に及ぼす影響について検討し，既存のすべり抵抗推定モデルの精度検証と粗さ指標の寄与度から，摩耗後のすべり抵抗の評価に有効な粗さ指標を推定した．既往モデルのデータを拡充した結果，十分な精度があることが確認され，モデルの粗さ指標の寄与度を確認した結果，マイクロテクスチャRa(0.1)およびMr1(0.5)が大きな影響を及ぼしていることが示された．また，特定した粗さ指標からほうき目仕上げによる凹凸の存在は，摩耗後のマイクロテクスチャRa(0.1)，Mr1(0.5)の持続性に寄与していることが明らかとなった．
