“…Cement can avoid forming a porous structure in the aggregate, which can increase the contact area between asphalt and aggregate. The adhesion of diabase is lower than that of basalt, which has a certain impact on water damage, and other properties are excellent, which is a relatively high-quality raw material for pavement engineering [14][15][16] . By adding cement, the adhesion of diabase porous asphalt mixture is improved.…”

Aggregate dispersion is one of the main diseases of porous asphalt. Reasonable material composition can effectively reduce the occurrence of dispersion disease. In order to study how to determine the volume index and mechanical properties of the mixture from the five aspects of asphalt, asphalt oil film thickness, coarse aggregate, fiber and filler, this paper selects different kinds of materials and different additions, based on the benchmark mix ratio, and carries out the Kentucky dispersion test to reduce the dispersion disease of the porous asphalt. Through the analysis of the test results, it is verified that adopting high-viscosity modified asphalt, increasing the thickness of asphalt oil film, adding lime or hydrated lime as filler, and adding a certain amount of fiber can enhance the anti-flying performance of porous asphalt mixture. At the same time, the article carries out experimental analysis of various additives for different materials. Finally, various material comparison schemes to improve the anti-flying performance of porous asphalt mixture were formed. In terms of the selection and use of raw materials, it provides certain guidance for the construction of porous asphalt.

“…However, given the lack of available details on supporting drainage facilities and schemes for permeable pavements, the drainage process of the storage water in the permeable pavements and underlayment was simplified in this study. Thus, further research will consider improving the simulation of the seepage and drainage process in the permeable pavements and underlayment (Li et al 2021) to establish the connection of the storage water with the surface runoff and drainage system.…”

“…However, due to the incompleteness of the rainfall-runoff processes, most of those models are inappropriate for simulating stormwater and pluvial flood conditions. Therefore, a category of coupled hydrologicalhydrodynamic models represented by SWMM (Storm Water Management Model) has been developed to simulate the surface rainfall-runoff processes in urban catchments (Li et al 2021). In addition, the MIKE FLOOD model (Hossain et al 2020) enables multi-directional coupling of the drainage network, urban surface, and river channel so that the flood propagation in urban areas can be accurately modeled.…”

With the implementation of low impact development (LID) in urban areas, it is necessary to quantify the actual effectiveness of LID facilities. In this study, a coupled hydrology-hydrodynamic numerical model was utilized to investigate the runoff control effectiveness of permeable pavements in the city centre of Shijiazhuang, China. Two groups of designed rainfall events with the same duration but different rainfall amounts and peak rainfall intensity locations were presented, and the effectiveness of permeable pavement was demonstrated by the reduction in the total runoff volume, water depth, and inundated area. The results indicate that the rainfall amount is the main factor affecting the runoff control of permeable pavements, and their effectiveness decreases with increasing rainfall amounts and peak intensity coefficients. Moreover, permeable pavements are more effective in reducing the residential waterlogging area, and the proportion of the inundated area above a depth of 0.2 m is considerably diminished. This study reveals the response of the runoff control of permeable pavements to different rainfall patterns, which is essential for supporting the design and practical operation of permeable pavements.

“…In recent years, cities are more susceptible to floods and water pollution after heavy rainfall due to the widely paved dense graded pavements in cities . Porous asphalt (PA) pavement is a type of porous pavement construction with well-developed interconnected voids that may effectively minimize surface stormwater runoff and alleviate urban floods and is now being implemented and promoted vigorously .…”

The objective of this study is to investigate the microevolution of the bitumen microstructure, polymer phase, and polymer–bitumen interaction of high-viscosity modified bitumen (HVMB) in reactive oxygen species (ROS) aging using the Viennese binder aging (VBA) method. First, the VBA system was utilized to age HVMB with different ROS concentrations. Then, an optical inverse bright-field, dark-field, and fluorescence microscope (OIM) was used to observe the bitumen microstructure, its evolution, and polymer structure degradation of HVMB during ROS aging. Afterward, ImageJ software was applied to quantitatively assess the bee structure size characteristics of bitumen and the distribution characteristics of the polymer. Finally, the differences in the distribution features of bee structures in the polymer zone (PZ) and non-polymer zone (NPZ) were counted to understand the polymer–bitumen interaction during ROS aging. The results show that the existence of polymers affects the distribution state of bee structures in bitumen significantly. The area ratio of bee structures and the average area of bee structures in HVMB both progressively rise with an increase in ROS concentration, although both are much less than those in base bitumen (BB). The destruction of the polymer phase starts from the inside of polymers during ROS aging. As the ROS concentration increases, the polymer degrades from the intact network structure to isolated small molecules. Polymer–bitumen interactions are widespread in HVMB. A large number of bitumen bee structures are also present in the PZ of HVMB. Moreover, the bee structures considerably grow in the PZ as opposed to the NPZ during ROS aging. The clarification of these microstructural characteristics lays the foundation for a deeper comprehension of the aging mechanism of HVMB induced by ROS.
