A Study to Evaluate the Seismic Response of Road Embankments
Soils and Foundations, 2009 ABSTRACT A crucial matter related to roads in seismic areas is to ensure viability during the post-seismic stages, especially if the road represents an important or unique way to reach towns that may be potentially hit by strong earthquakes. Verification of road viability under seismic actions requires not only safety assessment of the failure ...

Analysis of Road Embankment Slope Stability
Open Journal of Civil Engineering, 2018 The stability of earthworks (cuttings, embankments, dikes) and natural slopes is a problem that is of concern to geotechnicians, both practitioners and researchers. The disorders generated by breaking the slopes are usually spectacular, often destructive and sometimes murderers. Many methods of calculating stability have been proposed.

Design of Drainage Downspouts Systems over a Road Embankment
Water, 2023 Numerous studies have examined the complex relationship between factors like embankment downspout spacing, height, slope, and rainfall characteristics in the quest to find the best spacing for embankment downspouts. Defining the correct spacing between road drainage elements is of utmost importance in minimizing water flow on roadways.

CYCLIC STRENGTH OF ROAD EMBANKMENT SOILS
Journal of Japan Society of Civil Engineers, Ser. A1 (Structural Engineering & Earthquake Engineering (SE/EE)), 2009 2004年10月23日にの新潟県中越地震（マグニチュード6.8）が発生し，関越自動車道の堀之内IC付近から小千谷ICの付近まで盛土が大きく沈下·変形する被害が生じた．地震後に土質調査を実施したところ盛土内の水位が存在し，盛土下部は飽和していることが判明した．そこで，いつくかの盛土材料を用いて繰返し非排水せん断強度および繰返しによるせん断剛性の低下を繰返しねじり試験により調べた．その結果，繰返しせん断強度比は，不飽和土が飽和土より大きいことや，その値は塑性指数と相関があること，高い繰返しせん断応力比が作用した場合には，不飽和条件においても材料の軟化が生じることなどが判明した．

The effects of road embankments on the water environment, with focus on hydrography, zoobenthos and macrophytes – a follow up study [PDF]
, 2021 During the summer of 2020, a study on hydrography, sediment, zoobenthos and vegetation was conducted at three road embankments in the Åland archipelago. The same areas had previously been thoroughly surveyed in 2003 as well as shortly in the sixties and ...

Use of restoration plantings to enhance bird seed dispersal at the roadside: failures and prospects
Journal of Environmental Engineering and Landscape Management, 2015 Plantings are commonly used in roadside reclamation for ornamental purposes and for increasing slope stability and road safety. However, the role of these plantings in restoring ecological processes, such as seed dispersal, has received little attention.
