“…Intercepting the infiltration of rainwater road surface generates higher runoff than agriculture, forest or any other natural land cover (Ziegler and Giambelluca, 1997; Ziegler et al, 2000). An event-based experimental study shows that the surface runoff coefficient for paved and unpaved roads are >90% and ~80%, respectively, which is only 0%–20% in the agricultural fields, therefore the lower depth of rainfall is adequate to produce overland flow and subsequently increase soil erosion (Hou et al, 2020; Ziegler et al, 2000). The insufficient penetration of rainwater by impervious road surface also affects the process of sub-surface flow and groundwater recharge (Wemple and Jones, 2003), and the consequent result shows by severe water shortage, flooding, and waterlogging conditions in the urbanised area with a higher density of paved road (Gu et al, 2018; Kramer, 2013; Xiong, 2016).…”

Transport network infrastructure interacts with the earth’s surface because they often share common spaces (e.g. river valleys), such that transport is an anthropogenic pressure that can affect geomorphological processes and outcomes. Since having its profound effect worldwide, the systematic study on the effect of transportation infrastructures (TIs) on the alteration of geomorphological forms and processes has been less focused than on any other anthropogeomorphic driver. The present review provides a multidimensional overview based on the available literature and data on the effect of TIs in changing hillslope and fluvial geomorphology to sustain a peaceful harmony between the transport network and its surrounding landscapes. The study underlines the effect of major TIs like trails, roads, railways, tunnels, causeways, waterways and airports on the alteration of different geomorphological processes on hillslope and fluvial landscapes like the movement of earth material, geomorphic connectivity, slope instability, sediment production, gully initiation and surface runoff. For instance, the global level proximity analysis shows ~40% of landslides happen within the 500 m of any major roads only, while at the regional scale it becomes ~65% irrespective of the degree of seismicity. Due to the fast development of TIs, the mountain regions are more prone to slope instability because of the alteration of surface hydrology by increasing runoff, road and ditch guided concentrated flow, rills and gully formation by reducing drainage area to cross the critical threshold limit. The plain regions are primarily facing the problem of fluvial (dis)connectivity because of the close proximity between river and transport networks and undersized causeways. For sustainable TIs development, factors like the practice of bio-engineering for roadside slope management, de-culverting, 100-year flood return for causeway construction, mapping of river corridors, road water harvesting should be incorporated for less effect on hillslope and fluvial geomorphology.

“…Morgenstern and Nixon [5], and Foriero and Ladanyi [6] applied Terzaghi consolidation theory, the large strain thawing consolidation theory, and heat conduction equation to analyze the settlement of the saturated and unsaturated soil. Hou [7] adopted conservation law of momentum and mass, entropy inequality, and the mixture theory to established the settlement model. They considered the influence of the volume fraction condition.…”

The settlement in permafrost regions has a significant effect on the safety of the aircraft. Therefore, a numerical model of asphalt concrete pavement and subgrade in permafrost regions is proposed and verified by comparing with previous studies. Numerical models under the dynamic load of aircraft are used to analyze the settlement nephogram, time-dependent curve, and settlement curve. Results show that the influences of different parameters on settlements decrease slowly at the depth of 0–1.45m, then decrease quickly at the depth of 1.45-2m, finally tend to be stable. The peaks of settlements increase with the growth of international roughness index, taxiing speed, and aircraft’s weight. The settlement increases little when the international roughness index is more than 3. The settlement varies significantly when the taxiing speed is from 30m/s to 70m/s. The study provides a theoretical basis for the construction and maintenance of asphalt concrete pavement and subgrade in permafrost.

“…UGM has the advantage of permeability and drainage, which is one main concern for the current research on UGM used in permeable pavement [12,13]. Hou et al pointed out that permeable pavement can delay flood peaks due to the existing gravel base course and the drained subgrade [14]. Using an innovation approach, the permeability coefficient of different UGMs was obtained by Li et al [15].…”

Unbound granular materials (UGM) in permeable pavement will experience large numbers of infiltration during their service-life. The frequently changed moisture not only affects the cooling effect of permeable pavement, but also influences the mechanical behaviors of UGM. However, evidence is lacking to state the influence of infiltration on the behaviors of UGM, which is commonly in fully permeable pavement. Considering the influence of infiltration, this study conducted experimental tests to investigate the effect on the water-retaining and bearing capacity of UGM. With the water-retaining tests, the water-retaining rate in the whole structure and at different depths was analyzed under different infiltration numbers and duration. The results showed that the water-retaining rate increased with the extension of the infiltration duration. The infiltration duration had a significant influence on the water-retaining capacity of UGM, while the infiltration number had little. The difference in the water-retaining rate between the top and bottom layers was up to 2.56%. The water-retaining capacity of the integrated structure was hardly affected due to the dissimilarity of the water-retaining rate at different depths. With infiltrations, the fine aggregate in the upside structure migrated downward to the lower structure, resulting in a reduction in water-retaining rate in the upper structure and an increase at the bottom. In addition, the mechanical behaviors were evaluated by the traditional California Bearing Ratio (CBR) and repeated CBR tests under five infiltrations. The first and second infiltration had a significant influence on the CBR of UGM. With two infiltrations, the plastic strain increased by 57.8% via the repeated CBR tests. The resilient strain had an increase by 36.52% and the equivalent modulus decreased by 28.7% with the first infiltration. The first infiltration presented a critical influence on the bearing capacity of UGM and the effect decreased with the increase in the infiltration number. These findings will enrich the behaviors investigation of UGM and promote its application in the fully permeable pavement.
