Geogrids provide reinforcement for aggregate materials through interlocking between granular particles and geogrid apertures. The reinforcement or stabilization effect of a geogrid can be quite different when used with similar aggregate types but having different particle size distributions. This paper describes recent research efforts at the University of Illinois focused on triaxial compressi...

Localized strains due to production defects, seams, and punctured zones significantly affect mechanical performance of geosynthetic materials. Accurate determination of localized strains becomes particularly important for quality control/quality assurance evaluation of these materials and may play a critical role in design problems. A battery of tensile tests was conducted on 12 different geosy...

In the transition zone of railway tracks, track irregularities occur frequently due to differential settlement, which arises from difference between vertical supporting stiffness abutment and backfill. This is disadvantageous because it increases maintenance requirements deteriorates ride quality. To address this challenge, study proposes a strategy involving application cement-treated gravel r...

Abstract The highway section on the D3 Hričovské Podhradie – Žilina Strážov was carried out left branch of body overpass and right embankment body. stability ensured by a geosynthetics reinforced retaining wall. wall assembled from concrete prefabs, which uniaxial geogrids were attached. article presents numerical analysis deformations this structure in profile monitored geotechnical monitoring...

Bearing capacity of soil is an important factor in designing circular footing. It directly related to foundation dimensions and consequently its performance. The calculations for obtaining the bearing a needs many varying parameters, example type, depth foundation, unit weight soil, etc. In this work, comparison between values footing on gypseous before after improvement determined by two diffe...

The number of flood disasters has increased worldwide in recent decades. Identifying the optimal resolution or scale at which to represent digital terrain models DTMs is critical in order to improve our ability to accurately and efficiently model floods. Few studies have attempted to compare flood modeling results using different resolutions of DTMs in divergent environments. In this study floo...

The effectiveness of remedial measures for the stability onshore buried pipelines against uplift mechanism induced by soil liquefaction, in event an earthquake, is investigated through 1-g shaking table tests. This study aims at proposing mitigation solutions that may be alternative to already existing and currently adopted systems, accounting a set requirements cannot omitted context long trac...

The shear strength of geogrid-reinforced ballast is often dependent on the aperture size geogrids and nominal ballast. This paper presents a theoretical analysis based probabilistic mechanics how affects interaction between particles geogrid. Unlike past literature, in this study, properties particle distribution analysed using Weibull distribution. probability grain interlock proposed to descr...

Track thermal buckling is one of the primary safety issues continuously welded rail tracks. It has been shown that transition zones open deck steel bridges are more prone to track buckling, as loads from bridge and lower lateral resistance in this region can destabilize plane. The aim paper assess possibility reinforcing ballast layer with geotextiles mitigate problem zones. To do so, a number ...
