In this study, the performance of shred tire mixed with railway subgrade is evaluated to reduce environmental vibrations caused by trains’ passage. Since incorporating the Shred Tire seeds in soil affects on its shear strength and deformability parameters so, the first stage of the study was allocated to conducting a series of laboratory tests such as the unconfined compression test, and CBR an...

To effectively improve the tire grounding behaviors of wheelchair robots, an analytical method is proposed to analyze and optimize the tire grounding safety. Firstly, taking the cushion and tires as the vibration isolation elements with stiffness and damping, the vertical vibration model of the human-wheelchair robot is established. Then, taking the random excitation as the typical input, the f...

Microplastic content was analyzed in road dust, soils alongside roads and stormwater run-offs Al Ain City, Abu Dhabi. Apart from tire wear material, fibers degradation products of meso- macroplastics such as plastic bags bottle tops were found to be the most dominant microparticles. Speed bumps artificial turf/lawns also evaluated potential sources microplastics on roads. It that arid regions A...

The dissipated energy from periodic deformation is regarded as the main reason for heat generation and temperature rise inside the tire domain. However, the mechanical behavior of rubber parts is highly temperature dependent. In most performed investigations, the influence of thermal effects on stress/ deformation fields of pneumatic tires is ignored and just temperature distribution is conside...

Instrumentation to collect ISO2631 ride data was installed on a CaseIH 8950 tractor equipped with a central tire inflation system (CTIS). Data were collected at two speeds on three courses representing degraded secondary roads, moderately rough fields, and the toughest of farming conditions. Reductions in tire pressures available with central tire inflation resulted in greater tire deflections ...

A scenario of an automotive accident caused by tire failure is given followed by a human factors analysis of the information available to consumers on tire aging. Consumers have not been told that the age of the tire is a safety concern. It is not easy to decode the date of manufacture on tires. More publicity and prominent warnings are needed to communicate the dangers of older tires. Also, be...

ABSTRACT The issue of environmental protection has led researchers to pay serious attention to waste tires. Civil engineers have found that waste tires can increase bearing capacity, earth slope stability, and other useful applications in civil engineering. In this paper, a series of experimental modeling have been performed to investigate the effect of waste tires on increasing the stabi...

The tire-road friction coefficient is critical information for conventional vehicle safety control systems. Most previous studies in tire-road friction estimation have only considered either longitudinal or lateral vehicle dynamics which tends to cause significant underestimation of the actual tire-road friction coefficient. In this paper, the parameters, including the tireroad friction coeffic...
