Semicircular 3-point bending tests

Semicircular 3-point bending tests were carried out to evaluate the effect of induction heating on the healing of CIR mixtures (Figure 5). The tests specimens were preconditioned at −20 ± 2°C for 24 h before testing. Two supporting metallic pieces at the straight (bottom) edge and a loading steel ball at the midpoint of the semicircular arch comprised the test setup. The spacing between the two metallic supports was 60 mm (Figure 5). The test was carried out inside a climatic chamber at −20 ± 2°C at a loading rate of 5 mm/min.
