Abstract

During the course of building asphalt pavement, a lack of quality control will lead to the abandonment of the asphalt mixtures. One of the most common problems with asphalt pavement is rutting. Improving the construction’s quality is an important measure to reduce rutting. The purpose is to ensure the high-temperature durability of asphalt mixtures during the construction workflow to reduce the waste of asphalt mixtures, as well as to provide a methodology for the current monitoring of the quality based on the building information modeling (BIM). Rutting resistance was appraised utilizing the static uniaxial creep examination. Oblique photography technology was used to obtain terrain data. The software of Revit 2016 was used to build the spatial model of highways and bridges. The results show that the size distribution of particles, the asphalt proportion, and the forming specimen’s temperature are the vital elements influencing the high-temperature behavior. The gradation was identified as the most important factor. The second was the asphalt binder content. Gradation variation should be given more consideration during paving using asphalt mixtures. Furthermore, the developed BIM platform can also monitor rutting resistance to reduce rework during construction. Full article

Microscopic Properties of Asphalt and Polyethylene at an Extraordinary High Dosage through Molecular Dynamics Simulation

by Yuye Jin, Haoyi Li, Jie Chen, Qianqian Wang, Yanhua Bao and Shuguang Hou

Abstract

Using waste plastics in asphalt mixtures could be an exploratory way to dispose of waste plastics. This study aims to investigate the microscopic properties between asphalt and polyethylene (PE) at an extraordinary dosage of 20 wt.%. Various types of PE with different degrees of polymerization (DP) and structural configurations were considered. Molecular dynamics simulations were used to calculate the mechanical parameters, free volume ratio (FVR), and Flory–Huggins parameter of the resulting PE-modified asphalt (PEA). Two types of PEA were made and characterized by fluorescence microscopy. The simulation results indicate that the addition of PE reduces the density of modified asphalt by less than 5%, and a higher density of PEA is associated with a lower FVR. When the FVR is close, the mechanical properties are greatly influenced by the DP and configuration. The DP and the number of chains are the main parameters impacting the compatibility between PE and asphalt, based on the Flory–Huggins parameter analysis. Decreasing the DP of PE (e.g., 50, with a minimum Flory–Huggins parameter and a relative molecular mass of 1300) will significantly increase the compatibility between asphalt and PE. LDPE−2 has better compatibility with asphalt, possibly because LDPE−2 has higher purity. These findings provide valuable insights into plastic thermal cracking and industrial modification practices.

Investigation of Medium-Term Performance of Porous Asphalt and Its Impacts on Tire/Pavement Noise

by Hao Wu, Ge Wang, Mingliang Li, Yue Zhao, Jun Li, Dingding Han and Pengfei Li

Abstract

To assess the medium-term performance of porous asphalt pavement during service and its influence on tire/pavement noise level, a seven-year continuous observation and data analysis study was conducted. Key performance indicators were measured and calculated by using automated pavement technology testing equipment. The noise levels were tested by using the on-board sound intensity (OBSI) method on three types of porous asphalt pavements (PUC-10, PAC-13, and PUC-10 + PAC-13) and one dense thin layer course (DTC) for comparison. The findings indicated that the Damage Rate (DR) and Surface Friction Coefficient (SFC) of porous asphalt pavements diminished greatly over time, while the International Roughness Index (IRI) and Rut Depth (RD) remained relatively stable. The two-layer porous asphalt pavement showed the largest noise reduction over the medium-term. Compared to DTC, the OBSI noise levels of these structures were lower by 2.09 dB, 1.53 dB, and 2.88 dB, respectively. The OBSI was found to be closely correlated with the SFC, IRI, test speed, lane, and pavement type. The RD had a notable effect on the OBSI in PUC-10 pavements. In PUC-10 + PAC-13 pavements, a significant linear relationship was observed between the OBSI and SFC. This is mainly because of the polishing of the coarse aggregates, which leads to micro-texture reduction, high frequency noise increase, and SFC decrease. This study makes a valuable contribution to understanding the laws of porous asphalt pavement performance changes and the relationship between tire/pavement noise and pavement characteristics.

Abstract

To improve the quality of reclaimed asphalt pavement materials (RAPs) and reduce the variability of RAPs, a refined decomposition process was applied to treat RAPs. The change rule and variability of aggregate gradation, asphalt content, aged asphalt properties and aggregate (extracted) properties of RAPs were analyzed with different frequency parameters. In addition, the gradation variability control method and the asphalt content variability control method were used to calculate the maximum addition proportion of RAPs according to the quality control requirements of hot-mixing asphalt mixtures. The results indicate that the variability of aggregate gradation, asphalt content and asphalt properties significantly reduced for the refined decomposition RAP. Compared with the original RAP (0 Hz) of 4.75–9.5 mm and 9.5–19 mm, the “false particle” content of the refined decomposition RAP (50 Hz) reduced by 75.6% and 64.3%, respectively. The refined decomposition process is conducive to the road performance of recycled asphalt mixtures, especially the dynamic stability and the maximum bending tensile strain. Comparing the recycled asphalt mixture with the original RAP (0 Hz), the maximum bending strain of the recycled asphalt mixture with the refined decomposition RAP (50 Hz) increased by 69%, and the immersion residual stability increased to 87.9%. The refined decomposition process improves the quality of the RAP and provides a reference for recycled asphalt mixtures with a high proportion of RAPs. This study contributes to RAP high-level recycling and carbon reduction in the highway maintenance industry. Full article

Abstract

Pervious concrete is an innovative eco-friendly construction material. Through the application of mineral admixtures and microscopic analysis to optimize its performance and analyze its mechanisms, its traits as a sustainable building option may be further improved. This study primarily examines the impact of the optimal blend quantities of fly ash, silica fume, and reinforcing agent on the attributes, micro-morphology, and phase composition of porous concrete. The optimal admixture was chosen after analyzing the effects of various factors on the mix ratio and properties of permeable concrete. To understand the degree of impact, performance tests were conducted on the 28-day compressive strength, water permeability coefficient, and porosity. Furthermore, the micro-mechanisms of the admixtures and reinforcing agents on the properties of permeable concrete were analyzed from a microscopic point of view using scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. This research found that the advantageous properties of permeable concrete were enhanced by the simultaneous integration of appropriate quantities of fly ash, silica fume, and reinforcing agent. This resulted in a 28-day compressive strength of 18.33 MPa and a permeability coefficient of 8.27 mm/s. Compared with the unadulterated mineral admixture, the optimal admixture of fly ash, silica fume, and reinforcing agent at the same time increased the 28-day compressive strength by about double; the permeability coefficient was reduced by 36%, but it was still at a high level; and the measured porosity did not differ much from the designed porosity. Through thorough microanalysis, the hydration reaction was significantly improved, which could enhance the microstructure and pore structure of the concrete. This was supported by a substantial increase in the macroscopic compressive strength and a decrease in the water permeability coefficient, which were consistent with the aforementioned enhancement found in the microanalysis.
