“…This dynamic hydraulic scouring will gradually split asphalt binder film and finally develop into moisture damage in forms of raveling or potholes [8], which makes entire service properties and service life of asphalt pavement subject to be challenged. Moisture damage of asphalt materials induced by dynamic pore water pressure exhibits a totally different damage mechanism compared with that induced by static water immersion and freeze-thaw [9,57,58]. A series of water conditioning devices were developed [59][60][61][62] to simulate the environment of dynamic pore water pressure and evaluate the service life of asphalt materials.…”

Intense rainfall induced by climate warming is causing more common extreme meteorological events such as urban waterlogging in recent years. The urban waterlogging often has a wide-ranged severe impact on urban traffic. General intense rainfall weather makes urban transportation frequently be served in an environment with abundant water, which not only affects its operation safety but also challenges the service life of urban asphalt pavement. This paper presents a comprehensive survey on the influence of intense rainfall on urban transportation. The characteristics of meteorological phenomena such as climate warming, intense typhoon and rainfall, and urban waterlogging are firstly discussed. Then, Shenzhen, the city in south China, is chosen to analyze its historical meteorological variation in recent years, which was recently affected by a typhoon name Ewiniar in 2018 and caused severe waterlogging throughout entire city. Further, the operation safety of urban traffic is investigated with an increasing depth of surface runoff in intense rainfall weather, followed by the service life of asphalt pavement related to the moisture damage induced by dynamic pore water pressure. Finally, a series of measures to alleviate the effects of intense rainfall induced by climate warming on urban waterlogging and long service life of asphalt pavement are recommended.

“…Moisture damage is one of the most important drivers of asphalt pavement distress (Kakar et al, 2015). Due to its importance, UNE-EN 12697-12 (AENOR, 2009) was used to evaluate the water resistance of the HMA.…”

To guarantee sustainable construction, we investigated the reuse of construction and demolition waste (CDW) as recycled concrete aggregate (RCA) for the manufacture of hot-mix asphalt (HMA) in place of natural aggregates. The use of waste tire rubber as a bitumen modifier could be a means of improving the water resistance of these mixtures. In this investigation, moisture damage resistance of HMA for binder course, type AC 22 bin S, was analysed. Percentages of 0% (control mixture), 35% and 42% RCA were used in place of natural aggregates. Two types of bitumen have also been used: a conventional B35/50 penetration grade bitumen and BC35/50, a crumb rubber modified bitumen. Volumetric properties and water resistance were determined by means of indirect tensile tests. The results indicate that contrary to expectations, mixtures made with BC35/50 do not display better water resistance than mixtures made with B35/50. Nevertheless, a mixture made with B35/50 or BC35/50 does comply with Spanish requirements. Additionally, reversibility of moisture damage resistance was clearly demonstrated in this research. This research may help to better understand the performance of HMA made with RCA and the drawbacks of using waste tire rubber as a bitumen modifier.

“…e abovementioned phenomenon may result from the existence of several pathways through which moisture may permeate into the internal structure of the pavement. For instance, moisture may enter the pavement through cracks, voids, road shoulder edges, or through the bottom of the asphalt pavement by capillary action [6].…”

Moisture susceptibility plays an important role in the damage of asphalt pavement. Failure occurs when asphalt is removed from the aggregate particles due to the decreased adhesion between the asphalt and aggregate in comparison with that between water and the aggregate. In recent years, efforts utilizing nanomaterials to improve the diverse properties of asphalt have proven to be effective. In this study, three types of nanoclays were used to modify styrene-butadiene-styrene- (SBS-) modified asphalt. The resistances to water damage of the modified binders were evaluated using the surface free energy (SFE) and atomic force microscopy (AFM). The results revealed that the total SFE decreased and the energy ratio (ER) increased when the asphalt binder was modified with the nanoclays, indicating that the addition of nanoclays can improve the moisture resistance of these aggregate-binder systems. After immersion, a decreased amount of bee structures was observed in both the SBS and nanoclay-modified asphalts due to the interactions between water and bitumen. However, the residual amount of bee structures was higher in the nanoclay-modified asphalts than in the SBS-modified asphalt, indicating that the addition of nanoclay makes the surface morphology of asphalt more resistant to water damage. Finally, freeze-thaw splitting tests were used to verify the results obtained through the SFE and AFM tests.
