Performing Organization Name and Address Center for Transportation Research University of Texas at Austin Red River, Suite   The objective of this study was to evaluate the effects of truck tire contact pressure on pavement responses at different loading conditions. A tire footprint system was used to capture contact pressure patterns statically and dynamically (low speed) at three inflation .

    simulation based mechanistic-empirical method to identify and quantify the tire pressure effects on flexible pavement performance. In this study, measured non-uniform tire-pavement contact stress data for different tire load and inflation pressure conditions and for three popular tire/axle. Traffic related factors like axle load configuration, tire imprint area, tire inflation pressure, numbers of wheel load repetition have significant effect in the design of flexible pavement system. Stress-strain based analysis procedure is used in the finite element method to estimate those factors.

    On/Off-Highway Wide Base Drive Axle Radial. The key words behind this rugged tire are “performance,” “enhanced” and “robust.” It’s engineered for the tough terrain and extra duty of all-wheel-drive vehicles like front-discharge cement mixers, dump trucks and specialty oil field rigs.   Inflating a tire to a higher pressure increases the diameter slightly, but more importantly it reduces the degree to which the tire is 'flattened' at the point of contact with the pavement. This of course is the very reason that rolling resistance goes up as inflation pressure .

These relation­ ships can be used to evaluate the effects of truck tire inflation pressure and axle load on the structural capacity of pave-iv ments. The results can help to clarify many pressing prob­ lems, such as rutting, shoving, etc.

The objective of this paper is to evaluate and quantify the effects of truck traffic characterization in axle load spectra and high tire inflation pressure levels on predicted fatigue cracking performance.

This was achieved by evaluating a number of pavement sections using the mechanics-based fatigue cracking analysis framework.

This modified method is based on incorporating tire imprint instead of load over inflation pressure ratio and utilizing a more realistic representative value rather than tire inflation pressure. Measured tire-pavement interface stresses were studied to determine the effects of tire structure, load, and inflation pressure on the tire-contact stress distribution.

It was shown for the two tire types investigated, bias-ply and radial tires, that their loading patterns were different. The traffic load is distributed to the pavement through tires. Tires may be single or dual, their size and tire pres­ sures vary. The axles may be single, tandem or tridem and the load distribution is not always ideal.

The axle load is not always the nominal axle load but it may be considera­ bly smaller and overloads are not uncommon. However, when the tyre inflation pressure is kPa, the effect of static load distribution between the two axles has a negligible effect on performance.

At present, the mean tire inflation pressure in the U.S.A [5J ranges from to psi. In Europe, the super worries about its effects on pavement performance, since there is an increase in structural. Results from the tire study indicate that, for a ‐20 bias‐ply truck tire, the highest pressure in the tire‐pavement contact region is about two times the inflation pressure, for the ‐kPa and ‐kPa (75‐ and ‐psi) inflation pressures considered.

HOW TO WEIGH YOUR TRUCK. Be sure to weigh your vehicles, fully loaded, on a scale. Each axle, front and rear, and trailer must be weighed separately. Actual gross axle weights should be compared with the manufacturer's tire data book to determine the inflation pressure required. The load carried by each individual front axle tire should be noted.

A validation of the model was performed against experimental data found in the literature. A parametric analysis is presented in this paper to evaluate the effects of the following factors on truck skid resistance: truck speed, magnitude of wheel load, thickness of a water film on a pavement surface, and tire inflation pressure.

Lower tyre pressure can reduce significantly the amount of stress in the pavement and in the top part of unbound road structures and thus reduce the risk for permanent deformation. •Tyre pressure does not have any.
