Abstract: 本論文は,アスファルト混合物について引張試験を実施し,常温から-20℃の低温までの広温度領域にわたり破壊性状を求め,その応用についても述べたものである。引張試験では供試体の寸法効果も検討した。実験の結果,引張強度と温度との間に断面寸法に関係なく高い相関関係が認められた。また,アスファルト混合物の引張の破壊性状と熱応力破壊との関係や,ひずみ速度が広範囲に変化した場合の破壊性状等がこの結果より容易に推定でき,鋼床版舗装の縦き裂の主な原因の一つであるひずみの面からこのき裂現象を考察することが可能となった。
This paper describes the result of tensile test for asphalt mixtures over a wide range of temperature: from the ambient temperature to the temperature as low as -20℃. This paper also describes the application of tensile test and its size effect. Based on the test results, it was evident, regardless of the cross sectional area, tensile strength and temperature were linearly related, and the transition point and tensile strength of asphalt mixtures for unknown rate of strain can easily be estimated by three equations. Furthermore, it is considered that fractural behavior such as longitudinal crack in asphalt pavement on orthotropic steel deck bridge and transverse cracks in cold areas can be estimated based on tensile fracture properties.
