Evaluation on Stabilization Role of Lime and Cement in Expansive Black Clay–Oyster Shell Ash Composite
Transportation Infrastructure Geotechnology - - 2021
This research presents an experimental study to analyse the role of lime and
cement in amelioration protocols of expansive black clay (EBC) in the presence
of oyster shell ash (OSA) as admixtures. An optimal blend of 10%OSA was admixed
with cement and lime independently in stepped threshold of 2, 4, 6 and 8%,
respectively. The Atterberg limit, compaction properties, California bearing
ratio (CBR),...
The Search for Internal Stability in Reinforced Soil
Transportation Infrastructure Geotechnology - Tập 7 - Trang 378-389 - 2020
Professor Jonathan Wu’s career was devoted to rigorous development of internal
stability in reinforced soil as a new and evolving technology. This paper
presents two of Professor Wu’s students’ work on the search for internal
stability by tracing his work. Engineering design of reinforced soil originated
in France with Schlosser and Vidal in the late 1960s. The first designs were
based on a simple...
Application of Geocell Track Substructure Support System to Correct Surface Degradation Problems Under High-Speed Passenger Railroad Operations
Transportation Infrastructure Geotechnology - Tập 4 Số 4 - Trang 106-125 - 2017
Ballast fouling and associated degradation of track geometry is a serious
problem for railway systems in general and high-speed passenger rail systems in
particular. This paper presents the results of a field test on Amtrak’s
Northeast Corridor where a long-term problem area existed near Oakington Road,
Havre de Grace, Maryland, near MP 63.7 between Philadelphia and Washington DC.
This test looked...
Prediction of Multi-layered Pavement Moduli Based on Falling Weight Deflectometer Test Using Soft Computing Approaches
Transportation Infrastructure Geotechnology - - Trang 1-34 - 2024
The application of supervised machine learning algorithms to provide solutions
for various civil engineering problems is an emerging trend. This paper presents
the utilization of artificial neural network (ANN) and random forest regression
(RFR) for the prediction of the elastic moduli of multi-layered pavement based
on the falling weight deflectometer (FWD) test. The establishment of ML models
in...
Numerical Study of the Seismic Response of Closed-Ended Pipe Pile in Cohesionless Soils
Transportation Infrastructure Geotechnology - - Trang 1-27 - 2023
Closed-ended pipe piles are usually preferred over traditional piles because
they are simpler and easier to handle. Also, their quality could be verified
easily and at a low cost. However, the seismic response of these piles is still
not clearly understood. Therefore, this paper examines the seismic performance
of closed-ended pipe piles embedded in dry and saturated cohesionless soils
using a val...
Characterization and Modeling of Photon Absorption for Improved Accuracy and Consistency of Density Measurement Using Nuclear Gauge with Hydrogen Effects
Transportation Infrastructure Geotechnology - Tập 3 Số 2 - Trang 37-59 - 2016
The nuclear gauge test method, as a non-destructive method, has been used for
highway construction and compaction control since the 1950s. This method is
based on the attenuation of photons passing through materials to be tested.
Because the hydrogen atom has a different ratio of electron/atom mass from other
atoms, the content of hydrogen atoms in the bulk material may produce
significant effects...
Numerical Investigation of Dynamic Load Amplification in Buried Culverts
Transportation Infrastructure Geotechnology - Tập 5 - Trang 24-41 - 2017
Most traditional research on buried culverts has looked at live load
distribution through soil onto buried culverts without due attention to the
dynamic amplification of moving loads. Few studies that considered the dynamic
amplification of buried culverts modeled the system assuming plane strain
conditions. Under such conditions, finite area loads such as the wheel loads of
vehicles must instead ...
Correction to: Effect of Adjacent Support Condition on Premature Wood Crosstie Failure

Characterisation of High-Speed Train Vibrations in Ground Supporting Ballasted Railway Tracks
Transportation Infrastructure Geotechnology - Tập 7 - Trang 69-84 - 2019
Railway networks impose nuisances like vibration and noise onto structures and
the inhabitants proximate to railway lines. Tremendous increase in number of
passengers and freight carried across stations has led to faster trains with
high axle loads and longer trains with added number of coaches. Passage of
trains over railway tracks causes elastic rebound of the railway embankment and
ground durin...
