Summary: The study aimed to determine the optimal design of stone matrix warm mix asphalt containing crumb rubber modified binder (CRMB) using response surface method (RSM). Production temperature and the content of polyethylene wax and CRMB were considered as independent variables. Moisture sensitivity, flow number, resilient modulus, and critical stress intensity factor were used as response variables to determine the optimal design. The results showed that the prediction models of response variables can predict the performance results accurately. The optimal design of stone matrix warm mix asphalt containing CRMB at 135°C, 7.02% CRMB, and 2.1% polyethylene wax with a desirability of 0.765 were obtained using predictive models.

Summary: The application of hot recycled asphalt mixtures is becoming more popular in pavement engineering due to its environmental and economic benefits. The degree of blending (DOB) between virgin and reclaimed asphalt pavement (RAP) asphalt binders plays a crucial role in the performance of the hot recycled asphalt mixture. This paper reviews the current studies on the blending condition between virgin and RAP asphalt binders, introduces various theories and evaluation methods, discusses critical factors affecting the DOB, and suggests future research directions and challenges.

Summary: In this study, a graphitic carbon nitrite (g-CN) homojunction was synthesized and coated onto a 3D-printed photoreactor for the removal of Rhodamine B dye. The photocatalysis and adsorption experiments were conducted under visible light irradiation and in the dark. Various experimental parameters were investigated, and the adsorption mechanisms were evaluated using isotherm and kinetics modeling. The developed g-CN homojunction photocatalyst showed great potential for environmental remediation, particularly in wastewater management.

Summary: Uniaxial compression tests were conducted on asphalt mixtures with six loading rates to investigate their failure characteristics and modes. Acoustic emission (AE) technology was used to monitor the entire failure process, and typical AE characteristic parameters were analyzed. The results showed that the failure load and compressive strength of the asphalt mixtures increased significantly with the loading rate. Correlation analysis revealed favorable correlation and regularity in the amplitude-hits and amplitude-energy for loading rates of 0.2-5 mm/min, but no regularity for a loading rate of 0.05 mm/min. The dominant frequency of the AE signals ranged from 50-350 kHz, and the failure mode could be identified based on the difference in AE parameters and dominant frequency distribution.

Summary: The proposed research aims to evaluate the practical application of the reclaimed asphalt pavement (RAP) mixture fabricated from recycled aggregate with the low-viscosity extracted binder. Various mix designs and laboratory experiments were conducted to examine the characteristics of RAP specimens, and a full-scale testbed accompanied by Heavy Vehicle Simulator was performed in the field to verify the practical application of the best RAP mixture. The results suggest the importance of controlling the absolute viscosity of the extracted binder and the nominal maximum aggregate size of the recycled aggregate to ensure proper durability and performance of the RAP mixture.

Summary: This study investigates the mobilization stage of reclaimed asphalt pavement (RAP) binder and the diffusion stage of virgin binder in the blending process between RAP and virgin binder. A blending chart relating RAP binder content to carboxyl index (CI) of blended binder was established using Fourier transform infrared spectrometer (FTIR). The diffusion of virgin binder was studied using the tracing method. The results showed that the proposed indicators can comprehensively evaluate the blending efficiency between RAP binder and virgin binder.

Summary: This research evaluates the various performances of recycled warm-mix asphalt (RWMA), finding that increasing reclaimed asphalt pavement (RAP) content reduces moisture damage resistance and low-temperature performance, but this can be compensated by using warm-mix additive (WMA). By contrast, rutting resistance and fatigue performance improve with an appropriate combination of WMA additive and RAP content. Statistical analyses reveal that RAP content has the greatest impact on RWMA performance, while WMA additive type predominantly influences moisture susceptibility. The findings provide references for regulating RWMA performances by adjusting design components.

Summary: The research findings indicate that permanent strain decreases with increasing RAP content in asphalt concrete, but the lowest permanent strain is achieved at a certain level of oil content for each RAP content. WEO results in lower strain than WCO in the mixture. An interaction effect was found between RAP content and oil type in asphalt concrete.

Summary: The Fenton oxidation process was successfully applied to biologically treated swine wastewater (BSWW) for the removal of TOC and color constituents. By optimizing operational variables using the response surface method (RSM), it was found that FeSO4 is more important for TOC removal, while H2O2 plays a significant role in color removal. The optimal conditions derived through process optimization led to 76.7% removal of TOC and 98% removal of color from the swine wastewater.

Summary: This study examines the influence of using crude palm oil in hot mix asphalt with recycled asphalt pavement materials. Experimental results show that stability and indirect tensile strength increase with up to 80% recycled asphalt pavement material, but 100% RAP with crude palm oil reduces these strength parameters. Microstructural analysis reveals that the incorporation of CPO changes the structure of aged and virgin binder, forming new and unique phases. The statistical models are significant and well-fitted, validated through experiments with a low error rate, indicating potential for CPO as a bio binder material.

Summary: The activation level of binder from reclaimed asphalt pavement (RAP) is critical in designing recycled asphalt mixtures. It is found that RAP binder may not be fully activated, and different aging heterogeneities within RAP binder can affect mixture design. Blending charts for recycled asphalt mixtures should ideally be based on the properties of the active RAP binder to select the correct virgin binder.
