“…Previous studies have demonstrated that incorporating 5% POFA as a filler in asphalt mixes can enhance their properties [10]. It has been observed that a strong linear relationship exists between the fatigue life of asphalt mixtures and the requirement for 50% stiffness reduction, as reported by Cheng et al (2022) [11]. However, for the dissipated energy criterion, fatigue failure occurs with a stiffness reduction of only 30% instead of 50%.…”

Selecting suitable materials for sustainable asphalt pavement construction can be a challenging task, particularly due to the significant issue of fatigue damage in flexible pavement. The fatigue performance of gap-graded asphalt mixes (GGCP) was assessed through four-point bending beam fatigue testing, examining the impact of incorporating 6% Calcium carbonate (CaCO3) and 2% treated palm oil fuel ash (TPOFA) on fatigue cracking. The testing was conducted at various stress levels (800, 1000, and 1200 kPa) and a temperature of 5°C. Additionally, the asphalt mixtures underwent acceleration ageing and moisture conditions, which varied during the study. The experimental findings indicated that higher stress levels resulted in a decrease in the fatigue life of asphalt mixtures due to ageing effects. Moreover, moisture conditioning was found to diminish the fatigue life of the asphalt mixture. Comparatively, the fatigue model incorporating a plateau value and fatigue life demonstrated greater accuracy when compared to previous regression models.

“…Failures appear in the pavement layers in the form of spalling, loose binders, changes in the horizontal slope of the road, and longitudinal cracks at the junction of the old and widened portions of the road constructed on weak soils [39]. Vehicle speed, traffic load area, and temperature contribute to the load rate on the asphalt layers [40]. It is pertinent to mention that the mid-pavement-layer strains are more significant than in the top layers [21].…”

Embankment and pavement widening of an existing road is a viable option to cope with increased traffic volume. One of the common challenges in road expansion is the occurrence of differential settlement between the old and the new portions. This article pertains to the field case study of the National Highway-120, where pavement distresses developed in the weak sections of the highway following the operation of traffic within a few months. Field monitoring and geotechnical tests, including the requisite in situ as well as laboratory tests, were conducted on soil specimens from the study area, followed by the performance of a numerical analysis using the two-dimensional finite element software Abaqus CAE 2021 to investigate the weak section of the road. Different techniques such as geogrid reinforcement, installation of cement–fly-ash–gravel (CFG) piles, and lightweight foamed concrete (LWFC) embankment fill were used to analyze the reduction in differential settlement between the old and the widened portions. Among the applied reinforcement techniques, the use of LWFC as embankment fill in the widened portion was determined to be most effective in minimizing the differential settlement in the weak section of the highway.

“…You Peng et al determined the optimum content of Qingchuan rock asphalt through experiments, and studied the road performance of CQRMA [3]. In recent years, Chinese and foreign researchers have conducted studies on the high temperature stabilization of bitumen mixture using equipment other than the traditional rutting test, such as the Hamburg rutting test machine, the accelerated loading test machine, and the asphalt pavement analyzer (APA) [4]. Li Yaming contrasted the accelerated loading rutting test with the APA experiment and the standard rutting test, pointing out that it can more accurately mimic how ruts form in asphalt pavement when it is subjected to large loads and slow traffic [5].…”

The resistance of Chinese Qingchuan rock asphalt to rutting at high temperatures was examined in this paper. Base asphalt, SBS modified asphalt, China Qingchuan rock asphalt modified asphalt (CQRMA), composite modified asphalt by China Qingchuan rock asphalt and SBS modified asphalt (CQR-SBSMA) were created. The high temperature stability of “AC-10C + AC-16C” double-layer asphalt mixture composite rutting specimen was evaluated by 1/3 scale accelerated loading test. The results showed that the dynamic stability of asphalt mixture was increased by about 40% after modified by CQRMA. The time-dependent rutting curve of 1/3 scale accelerated full thickness rutting test is basically consistent with that of constant thickness conventional rutting test, the accelerated loading test can more accurately characterize the high-temperature rutting resistance of asphalt mixture or pavement and its performance attenuation lawThe contributions of different types of as-phalt binders to the high temperature stability of asphalt mixtures were in the order of CQR-SBSMA, SBSMA, CQRMA, and 70-A.
