Based on numerical simulation methods, the anti-clogging performance of various pervious pavement structures were investigated. Different structure models built to analyze effects different structures, top layer thicknesses and aggregate gradations performance. The results shown that compared with single-layer structure, double-layer has better maintenance efficiency. most serious clogging can ...

Abstract From the late 1960’s airport engineers developed special paving material for arresting aircraft gears in event of overrun as a partial extension runway end safety area. Such pavement surface material, inverting general concept, should be crushed over first pass gear wheels resulting to sink and being promptly arrested abrupt loss velocity, preferability avoiding lives injuries well wit...

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...

In support of the initiatives for implementing the new MechanisticEmpirical Pavement Design Guide (MEPDG) in Iowa, a preliminary sensitivity study was undertaken to assess the comparative effect of design input parameters pertaining to material properties, traffic and climate on performance of two existing flexible pavements in Iowa with relatively thick Asphalt Concrete (AC) layers. A total of...

Pervious concrete is an environment friendly solution for eliminating imperviousness-related drawbacks of conventional concrete. mixes are predominantly composed cement, coarse aggregate, and water. The partial or complete elimination fine aggregate results in porous structure, which influences performance pervious This article aimed at reviewing major factors involved the design mixes, namely ...

In this study, an artificial neural network was developed in order to analyze flexible pavement structure and determine its critical responses under the influence of standard axle loading. In doing so, more than 10000 four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, and subgrade soil were analyzed under the impact of standard axle loading. P...
