“…For the loading protocol, an initial load of 1 kN was reached in the first ten seconds, then, the loading mode was changed to CMOD control. Optimal loading rates were selected for different testing temperatures based on the authors' previous studies (Cannone Al-Qudsi et al, 2020).…”

Durability and Property Study of Decade Old Crumb Rubber Concrete Cored Specimens

Crumb rubber concrete (CRC) is a concrete that contains rubber crumbs. This article presents a study of three experiments on long aged CRC specimens that were cored from a decade old CRC bridge deck in Tianjin, China. The three experimental tests conducted were: (1) the flexural stress–strain test on semi-circular disk specimens; (2) the accelerated steel-rebar corrosion test and (3) the carbonation test. In addition, the in situ carbonation test was also carried out on the CRC bridge deck. The flexural stress–strain test results showed that the CRC semi-circular disk specimens exhibited a ductile pattern and high-energy absorbing capacity with its flexural tensile strength being at 5 MPa and the flexural modulus of 10 GPa. The steel corrosion rust rate via the calculation of steel mass loss before and after the test in the accelerated steel-rebar corrosion test remained extremely low. The carbonation test results showed that in comparison with the prediction of two popular carbonation models, the carbonation in the CRC bridge deck took place at a much slower rate during the last 13 years. All of the results obtained in this study are reported for the first-time and indicate that these CRC cored specimens exhibit good mechanical properties and excellent durability characteristics after a decade in service, which may provide the technical knowledge for the possible future application of CRC in concrete constructions.

“…31 In fact, these two test samples are among the most commonly used geometries for fracture toughness determination of asphalt concrete materials that have been employed by many researchers.

Opening mode fracture behavior of asphalt mixture is studied experimentally and theoretically using three full disk‐shaped specimens, namely, edge‐notched disk bend (ENDB), disk‐shaped compact tension (DCT), and center‐cracked Brazilian disk (CCBD). While the ENDB sample is subjected to pure bending, the BD and DCT specimens are loaded by diametral compression and pin loading tension, respectively. The experimental results showed the noticeable role of loading type on the cracking resistance of asphaltic mixtures such that the specimen loaded in diametral compression showed significantly smaller fracture toughness than the DCT specimen (that is loaded under tension). The KIc results determined from the ENDB also lie between the KIc of DCT and CCBD testing methods. The discrepancies observed between the experimental results of the three specimen types were related to different signs and magnitudes of T‐stress in these test samples. Accordingly, by taking into account the effect of such stress term via employing modified maximum normal strain theory, the mode I test data were predicted theoretically. Finally, the test data obtained from the CCBD and DCT samples were estimated in terms of the KIc of the ENDB specimen (as the reference sample).
