rutting in asphalt concrete is a very common form of distress in asphalt concrete pavement which unfortunately has been incurable to date. one of the prime reasons of rutting is attributed to the behaviour of asphalt binder at elevated temperature. this study has investigated the performance of polypropylene fibres modified asphalt concrete mix against rutting. two types of asphalt concrete sam...

The dynamic component of bridge traffic loading is commonly taken into account with a Dynamic Amplification Factor (DAF)—the ratio between the and static load effects on bridge. In design codes, this factor generally more conservative than in reality. Recently new method calculation had been developed. Data from 15 different bridges have analysed since then paper presents results analyses. back...

We investigate the large deformation and extreme load-management capabilities of a soft topologically polarized kagome lattice mapped to cylindrical domain through problem wheel rolling on an irregular surface. test surface–lattice interaction experimentally by subjecting 3D-printed topological prototype localized distributed boundary loads. This investigation reveals dichotomy in force transfe...

A cyclodextrin ring was face-selectively transferred between two stations linked by a 2-methylpyridinium group on an axle molecule.

Abstract This document reports a probabilistic approach for residual fatigue life predictions of cracked railway axle with allowance variability the input data. A NASGRO formulation was used such purpose, its main parameters considered as uncorrelated random variables varying in given ranges. load spectrum order to take into account actual loading conditions that these components undergo. The p...

Bicycles have been recognized for their advantages such as low environmental impact, health improvement, and maintenance of transportation function in times disaster, demand bicycles is increasing social conditions change. The pedaling a conventional bicycle nowadays turns crank to rotate the front gear, which transmitted rear gear by chain, axle wheel. Since require human power pedal, structur...

There is a need for vehicles to maneuver when there are traffic jams, overcome narrow streets and various obstacles. This leads increased requirements dynamism maneuverability of vehicles.
 The authors present the results development research steering control vehicle, which provides maneuverability. Such circumstances significantly affect increase in wheeled vehicles, including tractors, u...

[2]- and [3]-rotaxanes with a tetraphenoxy perylene diimide core were synthesized. Hydrogen bonding between the wheel and the imide changes the optical properties of the perylene chromophore: the absorption and fluorescence spectra are red-shifted. The decay times of the rotaxanes are shorter in comparison with that of the axle. Single molecule fluorescence measurements reveal relatively narrow...
