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...

Different supplementary cementitious materials are often blended with cement to produce sustainable concrete. More than not, the strength of concrete is compromised, if constituent not carefully selected. In this study, optimization properties cement-rice husk ash (RHA) was carried out determine best mix ratio that produced binary high strength. ratios and RHA were studied at a water 0.4 specim...

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...

In this paper, a lane detection algorithm is presented by considering geometry information of camera and road. First, the camera geometry information is used to divide the captured image into the road part and non-road part. Then, the histogram of intensity is applied to quantize the road image into a binary image such that the pavement is background and lane mark is foreground. Next, a modifie...

Recycled concrete aggregate, waste rock, crushed stone reclaimed asphalt pavement, clay brick, fine recycled glass, and gravel are some of the things that left behind when buildings torn down. These a big problem for many countries around world. More more people want to find smart ways use these substances make. To protect environment natural resources keep damage minimum, it is important deal ...

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...

Title: Modelling Aggregate Interlock Load Transfer at Concrete Pavement Joints Author: Anna-Carin Brink Supervisor: Prof Emile Horak Co-Supervisor: Prof Alex Visser Department: Civil Engineering University: University of Pretoria Degree: Philosophiae Doctor (Engineering)

Portland cement concrete (PCC) pavement undergoes repeated environmental load-related deflection resulting from temperature and moisture variations across pavement depth. This has been recognized as resulting in PCC pavement curling and warping since the mid-1920s. Slab curvature can be further magnified under repeated traffic loads and may ultimately lead to fatigue failures, including top-dow...
