Semi-circular notched beam testing procedure for hot mixture asphalt

摘要: The purpose of this study was to facilitate and improve the methodology used for hot mixture asphalt fracture evaluation establish a procedure overcome difficulty preparation beam samples testing. This research investigated compared stress intensity factor (KIC) determined by two test set-ups: semi-circular notched single edge tests. In addition, temperature effect evaluated determination KIC at different temperatures. Two Superpave mixtures were experimental verifications. Results illustrated that there no significant difference between tests within acceptable statistical margin error. Finite-element discrete-element models created aid in verification results from laboratory Further, temperatures showed si...
