The objective of the presented research is to develop an efficient control system for highway load effects that involves the control of various parameters including: truck weight (axle weights and axle spacing), truck load distribution on bridge girders, dynamic load, strain, stress and deflection of bridge components, and verification procedure for the minimum load carrying capacity. This stud...

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...

Many parameters such as dynamic load of tractor drive wheels influence the traction of tractors. An increase in dynamic load of drive wheel increases the net traction, but excess dynamic load decreases the tractive efficiency that must be avoided. Development of tractor-mounted implements due to good maneuvering and weight transfer from front axle to rear axle led to effective performance of tr...

Abstract—This study investigates how the site specific traffic data differs from the Mechanistic Empirical Pavement Design Software default values. Two Weigh-in-Motion (WIM) stations were installed in Interstate-40 (I-40) and Interstate-25 (I-25) to developed site specific data. A computer program named WIM Data Analysis Software (WIMDAS) was developed using Microsoft C-Sharp (.Net) for quality...

Roads and railways are in a sense the arteries that keep the lifeblood of the economy flowing. Approximately 70 percent of freight moves by road in South Africa and it is growing by approximately four percent per annum. Data and information on heavy vehicle (HV) volumes and axle masses are therefore indispensable to road authorities for design and maintenance purposes. Heavy vehicle data from t...

In this research study three dimensional (3D) finite element analysis are performed on a flexible pavement section for different material properties, temperature and loading conditions. The main objective of is to predict the rut depth under conditions temperature, loadings properties. Three model developed using ABAQUS depth. system assumed be an elastic multi-layers with each layer being isot...

In order to calculate the vehicle load model of Baijianhe Bridge, based on data health monitoring system, type, weight, wheelbase, and other information were counted processed diagraphed obtain probability density distribution. At same time, automobile parameters relative national current code finite element method are calculated. The results show that 2-axle 6-axle vehicles main types, account...

This study investigates how shape optimisation affects the ultimate fatigue strength of a mechanical part. The mechanical part chosen for this investigation is an axle guard of running gear elements of the Hccrrs 2x2 axle car-carrying wagon. The static and fatigue strength analysis procedure according to the UIC 517 standard and numerical methods have been applied. Material properties were dete...

In the trials of present work, a double-axle trailer with carrying capacity 6 tons and hydraulically effective mechanical brake were used as tractor towed car. There is hydraulic system on each axle agricultural trailer. order to separate axles from other, mechanically controlled 2/2 directional control valve was mounted both inlets. The study carried out at constant speed (25 km h-1), stabiliz...
