“…However, the combined effects of change in frequency (25 Hz to 25/3 Hz) and change in signal shape (sine for tandem) are fully compensated. It is found that damage caused by the dualaxles is much higher than single axles, for the same strain levels [44]. Fatigues laws confirm previous findings by similar slopes, where the difference only appears from the second decimal place to the order of 3 %.…”

Asphalt mixture in pavement is exposed to a fatigue phenomenon which often causes its failure after a certain period of operation. Conventionally this is simulated in the laboratory by a mechanical stress in the form of continuous sine under the effect of a single axle. In recent years the designs of aircraft and large vehicles have changed a lot, given the needs in volume and transport capacity requested. We often see the tandem axles, tridem axel etc. Damage of asphalt mixture is related to vehicle characteristics (number and loads per axle, suspension type, speed, tyre type and configuration...); rest period, temperature and pavement material properties. Modern conceptions of jumbo aircraft type (e.g. Airbus A380, B777 etc…) and new designs of heavy trucks have imposed other forms of solicitation. This type of loading is dual axles with higher strain amplitude. Currently the road pavement and airport asphalt are subject to high levels of strain (or stress) of short duration at each passage of axles. The choice of the structure and the sizing of a roadway require consideration of several technical criteria, economic and geographic, such as heavy traffic and its developments. In this context, fatigue tests were carried out under load at large deformation (high strain amplitude) and can have multipeak shapes (tandem low valleys between two successive peaks). These tests were used to assess and compare the effect and aggressivity of large amplitudes of strain in terms of life, according to two types of signals (single axle and tandem).

“…(ii) Augmentation of heat-related pavement diseases, such as rutting [26]. Under the combination of traffic loads and extreme temperatures, asphalt pavement is subject to plastic deformation, or so-called rutting, resulting in the reduction of the roadway's functionality, as well its level of safety [27,28]. (iii) Increase in urban island heat effects [28,29].…”

Continually using fossil fuels as the main source for producing electricity is one of the main factors causing global warming. Through the past years, several efforts have been made, looking for sustainable, environmentally friendly, and clean energy alternatives. Harvesting geothermal energy from roadway pavement is one of the alternatives that have been developed and investigated recently. Herein, a systematic review and bibliometric analysis were conducted to provide a comprehensive overview of the potentials of harvesting thermal energy from asphalt pavement and to assess the level of achievement being attained towards developed technologies. A total of 713 articles were initially collected, considering the period between 2006 and 2021; later, a series of filtration processes were performed to reach 47 publications. The thermal energy harvesting technologies were categorized into three main sectors, at which their basics and principles were discussed. In addition, a detailed description of the systems’ configurations, materials, and efficiency was presented and described. Finally, gaps and future directions were summarized at the end of this paper. The fundamental knowledge introduced herein can inspire researchers to detect research gaps and serve as a wake-up call to motivate them to explore the high potentials of utilizing pavements as a clean and sustainable energy source.

“…Furthermore, numerous studies have proposed quantitative methods for investigating damage and establishment of constitutive models [5,7,[19][20][21][22], but these methods still have some shortcomings in reflecting the damage evolution and establishment of constitutive models of materials. From a macroscopic perspective, the influence of the change in the material structure on the mechanical properties has received increasing attention.…”

The mechanical response characteristics of large stone asphalt mixtures (LSAMs) are key factors in studying its fatigue characteristics during cyclic loading tests. Based on disturbed state concept (DSC) and viscoelastic continuum damage model (VECD), a series of tests using an overlay test (OT) were carried out to investigate the fatigue characteristics of LSAM. The results showed that disturbance and damage increased with decreasing frequency and increasing loading displacement and aging degree, while the asphalt content had no obvious adverse effect on the increase in damage. In addition, the disturbance and damage grew rapidly in the early stage of loading and reduced in the later stage of loading. On the contrary, based on DSC, the constitutive model modified with disturbance function (D) defined by external work could describe the mechanical properties, and the evolution process of disturbance function (D) could reflect the damage change in cyclic loading tests. The research conclusion can enrich the theoretical research on the fatigue failure response and mechanism of LSAM under cyclic loading and expand the application scope of DSC in the field of pavement.
