THE STUDY ON FLEXURAL STRENGTH AND FATIGUE LIFE OF AIRFIELD CONCRETE PAVEMENT

空港コンクリート舗装の切出し供試体曲げ強度試験結果および疲労寿命への影響

To study the chronological change of airfield concrete pavement, examination was carried out to inspect the cutout specimens. The specimens were sampled from operated airport apron in Haneda International Airport. The specimens were analyzed in basis of place where it was sampled, types of equipment used to lift the specimen, and flexural strength. The examination was evaluated based on the types of lifting-equipment and initial flexural strength. The result has yielded an increase in flexural strength over time in all conditions. In response to the result obtained, Consecutive Fatigue Index was calculated with fatigue design method using fixed flexural strength and design method factoring the increase of flexural strength. Consecutive Fatigue Index calculated with the method factoring the increase of flexural strength showed smaller value, meaning longer fatigue life.　打設後年数が経過した空港コンクリート舗装の性状を把握する目的で切出し供試体曲げ強度試験を行った．切出し供試体曲げ強度試験に用いる供試体は，東京国際空港国際線地区において施工されたエプロン舗装より採取した．試験結果として供試体の採取位置，採取方法，曲げ強度試験結果を示した．さらに曲げ強度の比較結果として，供試体採取方法の違いによる比較結果，施工時強度と切出し供試体曲げ強度の比較結果を示した．また，既往の設計法と強度増加を考慮したコンクリート強度を用いた疲労設計法による累積疲労度の比較を行った．コンクリートの強度増加は，今回の切出し供試体曲げ強度試験結果および過去の報告から設定した．累積疲労度は，強度増加を考慮したコンクリート強度を用いて疲労設計を行うことで低減される結果となった．
