| Abstract: | 本研究は，載荷走行時のアスファルト混合物層下面における鉛直応力の相対的な分布を動的荷重センサーを用いた室内走行実験より求め，荷重や混合物温度の変化が荷重分散の特性に与える影響を検討した。この結果と弾性および粘弾性理論による応力解析結果との比較も行った。実験の結果，実際の荷重分散は弾性および粘弾性理論による解析結果よりも広範囲に及ぶこと，本実験で対象とした範囲での混合物温度の変化は荷重の分散特性に大きく影響を及ぼすが，荷重の大きさが同特性に及ぼす影響は小さいことなどを明らかにした。 | | This paper describes the effects of wheel load and temperature of asphaltic mixture on properties of load distributing characteristics, estimated from relative distributions of vertical stress at bottom of asphaltic mixture and analyzed on basis of wheel tracking test using a dynamic sensor. Such relative distributions of vertical stress and the effects were compared with those computed by elastic and viscoelastic FEM. By using the same method of analysis, relation between depth of rutting and relative distribution of vertical stress at bottom of asphaltic mixture, was also investigated. The conclusions obtained follows: Load distribution by wheel tracking tests were broader than those by FEM. Changes of temperature of asphaltic mixture affected remarkably the load distribution but changes of load had hardly any affects. |
