“…It is important to conduct field tests to evaluate the effectiveness of certain newly developed materials or pavement structures [41][42][43][44] for their further application and promotion. In this case, numerical simulation can be firstly conducted to lay solid foundations for the preparation of relevant field tests and then to further explore the deep mechanical behaviors of asphalt pavement.…”

Asphalt pavement, which is mainly made up of the asphalt mixture, exhibits complicated mechanical behaviors under the combined effects of moving vehicle loads and external service environments. Multi-scale numerical simulation can well characterize behaviors of asphalt materials and asphalt pavement, and the essential research progress is systematically summarized from an entire view. This paper reviews extensive research works concerning aspects of the design, characterization, and prediction of performance for asphalt materials and asphalt pavement based on multi-scale numerical simulation. Firstly, full-scale performance modeling on asphalt pavement is discussed from aspects of structural dynamic response, structural and material evaluation, and wheel–pavement interaction. The correlation between asphalt material properties and pavement performance is also analyzed, and so is the hydroplaning phenomenon. Macro- and mesoscale simulations on the mechanical property characterization of the asphalt mixture and its components are then investigated, while virtual proportion design for the asphalt mixture is introduced. Features of two-dimensional and three-dimensional microscale modeling on the asphalt mixture are summarized, followed by molecular dynamics simulation on asphalt binders, aggregates, and their interface, while nanoscale behavior modeling on asphalt binders is presented. Finally, aspects that need more attention concerning this study’s topic are discussed, and several suggestions for future investigations are also presented.

“…The service life expectancy of weakened pavements can be shortened, and the pavements may collapse in extreme cases. According to the above principles, the American Association of State Highway and Transportation Officials (AASHTO) developed an empirical method to evaluate the pavement mechanical responses to flood and thus to measure flood damage to pavements (Elshaer and Daniel 2018;Matini et al 2022). Nevertheless, Khan et al (2014) believed that the consequences of pavement flood damage are also probabilistic in addition to the determined derivation results.…”

Climate change and urbanization are increasing the risk of flood disasters in vulnerable areas. Urban road infrastructure can be affected by floods, and subsequent restoration creates an additional carbon emission burden. These emissions are likely to compromise local decarbonization efforts, but there remains a lack of tools for quantifying the environmental impact of reconstruction projects after disasters. This study aims to develop an assessment framework to reveal the carbon footprint of post-flood road network restoration projects. An interdisciplinary model was developed, integrating knowledge in hydrology, civil engineering, and environmental science. This paper presents scenario simulations with the maximum flood depth (MFD) ranging from 0.1 m to 5.0 m and a case study in Carlisle, UK. Results show that floods with MFD over 0.5 m had significant impacts on pavements. The resilience to floods on low-volume roads was weaker, but the restoration emission intensity of main roads was significantly higher. From the perspective of an urban case, after a 70-hour flood event with an average MFD of 0.9 m, the total carbon footprint of road network restoration was 73.89 tCO2e, offsetting about 0.49% of local carbon reduction efforts for the month. Specifically, emissions from restoring low-volume roads accounted for 58.64%. Indirect carbon emissions from material production (approx. 66%) and delivery (approx. 30%) were much higher than direct emissions from onsite tasks (approx. 4%). Measures such as material improvement, delivery optimization, and construction material reuse can help mitigate the emission burden of restoration projects. A major uncertainty in the computation was ignoring the differences induced by the climatic context, but addressing this limitation would require support from pavement damage experts. This study provides quantitative tools for understanding infrastructure-related environmental impacts caused by flood disasters. The assessment framework proposed in this work is also expected to be applied to wider spatial-temporal scenarios to enrich decision-making references.
