this paper aims to assess the application of support vector machine (svm) regression in order to analysis flexible pavements. to this end, 10000 four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

Highway subgrade bears millions of traffic loads over the years, and its strength, stiffness, long-term stability gradually decline. In this paper, dynamic triaxial tests were carried out to study time evolution spatial distribution strain pore pressure highway-subgrade soil under action load. The influence load on deformation was analyzed. Furthermore, a numerical-calculation model established...

This paper reports the analysis of methods for estimating technical condition subgrade underneath a constructed railroad track or road during its operation. The study results have proven that issue related to monitoring and controlling high-quality compaction heterogeneous remains relevant requires construction reliable experimental assessing degree compaction. A procedure determining in labora...

The instability of railway tracks including mud pumping, ballast degradation, and differential settlement on weak subgrade soils occurs due to cyclic stress from heavy haul trains. Although geotextiles are currently being used as a separator in highway embankments, their ability prevent the migration fine particles reduce pore pressure has be investigated under adverse hydraulic conditions subs...

Railway track-bed materials are mostly in unsaturated state, and their hydro-mechanical properties depend strongly on their water contents or suctions. In France, problematic soils such as collapsible loess and swelling marl can be origin of instability problems for new lines for high speed trains, while the hydro-mechanical behaviour of interlayer soil formed mainly by interpenetration of ball...

The Heavy Weight Deflectometer (HWD) test is one of the most widely used tests for assessing the structural integrity of airport pavements in a non-destructive manner. The elastic moduli of the individual pavement layers predicted from the HWD deflection measurements through inverse engineering analysis are effective indicators of pavement layer condition. The primary objective of this study wa...

A geotechnical evaluation of some soils in Numan, Adamawa, North –East, Nigeria has been carried out. This was done to determine the suitability of the soils for use as subgrade/filling, sub-base and base course materials for road construction. The samples were collected from five different areas, at surface and sub-surface levels. The areas are New Demsa, Farei, Dowaya, Numan Town and Imbru. T...
