“…For identifying rheological properties in the low-temperature range, the DSR is usually equipped with a 4 mm plate-plate test setup. With this setup the linear viscoelastic properties can accurately be analyzed using the oscillation mode, as previously demonstrated by various authors (Sui et al, 2011;Lu et al, 2017;Riccardi et al, 2017;Laukkanen et al, 2018a;Büchner et al, 2019;Wang et al, 2019b;Grazulyte et al, 2019;Hajj et al, 2019;. Alternatively, the relaxation properties, which significantly governs the asphalt mixture low-temperature cracking resistance, can be determined by applying a relaxation test using the quasistatic mode of the DSR (Büchner, 2021;Büchner and Wistuba, 2022a).…”

A novel Three-Point Bending Beam Test (3-PBT) using a Dynamic Shear Rheometer (DSR) with linear drive motor is introduced for testing asphalt binder at low temperature conditions. This 3-PBT in DSR can be used as surrogate for Bending Beam Rheometer (BBR) tests. Advantages in comparison to BBR are that (i) 3-PBT works without harmful cooling medium ethanol, (ii) the amount of asphalt binder for testing is significantly lower (using material equivalent of 10% of BBR tests), (iii) a silicone rubber mold is used for specimen preparation instead of standard aluminum mold for BBR tests, which makes handling easier, and (iv) the loading protocol is more practical without applying contact load manually. The novel 3-PBT in DSR is presented with respect to preparation, installation, and conditioning of specimens, as well as to the loading protocol. Tests were conducted at temperatures of −10, −16, and −20°C. For the purpose of comparison to BBR tests, and of identifying most suitable testing conditions from alternative setups, a test series was run including 9 different asphalt binders. As to BBR tests, two different cooling media were used, i.e., ethanol and air. Finally, all test results obtained from DSR and BBR tests were analyzed in view of precision and correlation. DSR results correlated well with BBR results, while precision of 3-PBT in DSR was found to be satisfying.

“…During the construction process of highways, harmful gas emissions will be generated. Therefore, in the feasibility analysis stage of new energy construction, it is also necessary to analyze environmental emissions (Renken et al, 2018;Büchner et al, 2019;Walther et al, 2019;Wu et al, 2024). In terms of environmental impact, (Vergara-Zambrano et al, 2022), proposed a design method for a solar-biogas hybrid renewable energy system that can help reduce environmental pollutant emissions by 30%-80%.…”

Highways consume a significant amount of electrical energy annually, especially in remote desert regions where the cost of electricity is high. This research explores the utilization of natural resources along desert highways to establish hybrid energy generation systems for service areas. Three service areas along the desert highway in northern Xinjiang, China, serve as case studies. To assess the feasibility of hybrid energy generation systems in these service areas, meteorological data for the three locations were obtained from the NASA platform. The HOMER Pro software was employed for technical, economic, and environmental analyses of the systems. The results indicate the feasibility of Photovoltaic (PV)/Wind/Battery hybrid energy systems in the Huanghuagou, Kelameili, and Wujiaqu service areas. The application of these hybrid energy generation systems across the three service areas could provide 3,349,557 kWh of electrical energy annually for the desert highway. Sensitivity analysis reveals that the Net Present Cost (NPC) and Cost of Energy (COE) values decrease with increasing radiation levels, while NPC shows an increasing trend with growing load demand, and COE exhibits a decreasing trend. Among the three regions, Wujiaqu demonstrates the highest economic viability, with a COE of $0.34/kWh and an NPC of $3,141,641/kWh. Furthermore, Wujiaqu exhibits the lowest environmental impact, with CO2 emissions of 198,387 kg/yr, SO2 emissions of 493 kg/yr, and NOx emissions of 1,711 kg/yr.

“…Compared to the hot central plant recycling technique, the HIR technique started later, with lower technological maturity and adoption levels [10]. A white paper published by the International Energy Agency in 1997 noted that while several countries have adopted the HIR technique, only a few have a high level of promotion, and it is less commonly used for highways [11][12][13]. However, due to its advantages, such as the high recycling rates of RAP materials and minimal impact on traffic, HIR has gradually gained attention in European and American countries.…”

The substantial accumulation of reclaimed asphalt pavement (RAP) poses a pressing issue in road construction. The hot in-place recycling (HIR) technique has garnered widespread attention due to its high recycling rates of RAP and minimal environmental hazards. This study focuses on the RAP analysis, compaction characteristics, and field evaluation of hot in-place recycled asphalt pavements (HIRAP). Firstly, a novel test method of RAP analysis was proposed to evaluate the suitability of RAP. Subsequently, compaction tests reveal the compaction characteristics of hot in-place recycled asphalt mixture (HIRAM). Finally, the field performance of HIRAP was assessed. The research findings indicate that the RAP analysis method can accurately characterize the status of RAP. Increasing the RAP temperature improves the compaction characteristics of HIRAM. The field tests show that using HIR technology improves the performance of the pavement, in particular with a compaction of 99.7%. This study will establish a theoretical foundation for further promoting the HIR technique.
