“…Fenix test was compared with Semi-Circular Bend (SCB) test in the assessment of fracture behaviour of different types of mixtures. Both tests gave similar results about the effect of loading rate and temperature (Pérez-Jiménez et al, 2013).…”

There is a great interest in increasing the amount of recycled material used in asphalt mixes because of the beneficial impact on the environment. This is leading to the development of different recycling procedures, from cold in-situ to hot in-plant recycling. The objective of the study presented in this paper is to evaluate cracking resistance of recycled mixes manufactured by three types of processes, i.e., cold with emulsion, hot with high penetration bitumens and hot with emulsion (half-warm mixture), using 100% of reclaimed asphalt pavement (RAP) at different temperatures. Differences in their workability and ease of use are also analysed by gyratory compaction.

“…On the other hand, six replicates can be produced from each superpave gyratory compactor cylindrical sample leading to reduction of discrepancies in asphalt mixture properties due to inherent heterogeneous nature of these randomly distributed composite materials. The SCB testing configuration has been applied in estimating the fracture properties of many brittle and quasi‐brittle materials and also asphalt concretes . The behaviour of asphalt mixtures at intermediate ambient temperatures does not follow the framework of linear elastic fracture mechanics, and it should be described by nonlinear fracture mechanics approach.…”

Load‐induced cracking is one of the primary forms of distress in asphalt pavements at intermediate temperatures. Binder modification is a good alternative to promote the cracking resistance of asphalt mixtures. In the current research study, the effects of carbon nanotubes as a binder modifier on the fatigue and fracture performance of asphalt mixtures are investigated. The carbon nanotubes are added at five different percentages ranging from 0.2% to 1.5% to the base binder to study their effects on the fracture resistance and fatigue life of the asphalt mixtures. Using the cracked semi‐circular bend specimen, the critical value of J‐integral (Jc) was obtained for the investigated modified asphalt mixtures. Also, the fatigue behaviour of asphalt mixtures was studied using flexural beam fatigue test specimen. By employing the ratio of dissipated energy change approach, the plateau value of tested mixtures was determined as a measure of fatigue performance. Results showed that the carbon nanotubes can enhance both fracture resistance and fatigue performance of tested asphalt mixtures especially at higher percentages of the carbon nanotube.

“…Among several methods and tests of asphalt mixture failure, semicircular bending test (SCB) due to efficiency, reproducibleness, possibility of creating different modes of failure and practical methods to determine the behavior and failure of asphalt concrete has attracted attention to the asphalt pavement society [7]. The results of the semicircular bending test indicate the effect of variables such as loading rate, sample thickness and experiment of temperature in the test [8]. The failure characteristics of the cracked asphalt mixture are not considered and factors such as the type of traffic passing, the speed of the passing vehicles, and the grading of the sample are not taken into line with the actual conditions that can affect the results of the studies [9].…”

The failure of cracking is one of the main concerns regarding the performance of hot mix asphalt (HMA). Since the characteristic of the materials of the mixtures has impact on their cracking potential, the main conception of this research is to evaluate the effect of the type of size and additive percentage of crumb rubber modified (CRM) on the resistance of mixtures to crack at mid and low temperatures. For this purpose, rubber bitumen containing 10% and 15% crumb rubber with fine and coarse sizes with wet process was prepared. Asphalt mixtures with dense and gap grading were designed by using rubber bitumen produced by superpave method. The three-points bending test of semicircle bending sample (SCB) was used to evaluate the fracture characteristics of asphalt mixtures at low and middle temperatures (25&deg;C and -12&deg;C). Accordingly, the failure characteristics of asphalt mixtures were evaluated in two modes with short-term and long-term aging. The failure test results indicated that the produced mixtures with crumb rubbers additive have high resourcing resistance compared to control mixtures (without crumb rubber additive), were also revealed. Mixtures with dense grading and fine crumb rubber have high fracture resistance compared to mix with gap grading and coarse crumb rubber. Also, the increasing of the percentage of crumb rubber improved the resistance of the mixed failure. In general, it can be stated that the addition of crumb rubber increases the fracture resistance of asphalt mixtures which can improve its performance before cracking at mid and low temperatures.
