    Road surface textures are deviations from a planar and smooth surface, affecting the vehicle/tyre interaction. Pavement texture is divided into: microtexture with wavelengths from 0 mm to millimetres ( in), macrotexture with wavelengths from millimetres ( in) to 50 millimetres ( in) and megatexture with wavelengths from 50 millimetres ( in) to . slipping, or dragging tires and the pavement surface, is the dominant contributor of overall noise, particularly when vehicles are moving at higher speeds. Therefore, a number of research studies have been conducted to identify and analyze the factors affecting the generation of tire-pavement interaction noise.

    The Standing Technical Committee Pavement Surface Properties and Vehicle Interaction can trace its beginning to when it was first convened as the Road Surface Properties Related to Vehicle Performance Committee. Like then, the committee is concerned with the interactions between the vehicle and traveled pavement surface as they affect safety, comfort, . Road surface roughness excites low- and high-frequency vibration modes of a heavy articulated vehicle body. These vibrations result in motions in all directions that detract from the driver’s perceived ride and comfort and increase pavement damage due to dynamic wheel loads (DWLs).

    The present study involves field testing of a tire-loading-based theory of pavement traction in place of the traditional coefficient of friction. An associated hypothesis concerns the indicated existence of a fourth rubber force, surface deformation hysteresis, which is theorized to be independent of tire loading during tire sliding. The texture of pavements is important on all roads and should be optimized for optimum car tires traction, low running noise, car stability, low fuel consumption, even in rainy conditions. The subject of the paper is still interesting, even if 30 years have passed since the experimental research and the authors' first report (, []).

Transportation Research Board. Committee on Surface Properties--Vehicle Interaction.; National Research Council (U.S.). Interaction between Vehicles and Pavement Surfaces This issue contains five papers concerned with the interaction between vehicles and pavement surfaces.

Specific topics addressed include: blank and ribbed test tires for wet pavement friction evaluation; seasonal variations in skid resistance; hydroplaning; pavement contaminants and skid.

Pavement vehicle interaction (PVI) is a concept that looks at the interaction between a vehicle’s tires and the roadway surface on which it is driving. It is also known as rolling resistance. Three factors relating to a road’s surface condition and structural properties contribute significantly to PVI.

The friction force between tire and pavement is generally characterized by a dimensionless coefficient known as coefficient of friction (µ), which is the ratio of the tangential force at the contact interface to the longitudinal force on the Size: KB.

Contents. Standing Committee on Pavement Surface Properties and Vehicle Interaction (AFD90). The Committee is concerned with the interactions between the vehicle and traveled pavement surfaces as they affect safety, comfort, convenience, sustainability, and economics.

In future, the Committee believes that use of 3-D data collection will play a major. Second, the complex interaction between vehicles and pavements leads to the effects of road surface conditions, vehicle parameters, and driving speed on pavement dynamic loads were analyzed.

The thermal interactions between pavement and building/vehicle surfaces and the specific impact on energy use for cooling and heating in different seasons over a year need to be estimated. The effect of cool pavements on the improvement of outdoor human thermal comfort has not been investigated.

19 CHAPTER 4. PAVEMENT FRICTION AND SURFACE TEXTURE PAVEMENT FRICTION Definition Pavement friction is the force that resists the relative motion between a vehicle tire and a pavement surface.

This resistive force, illustrated in figure 8, is generated as the tire rolls or slides over the pavement surface. Figure 8. The paper tackles the theme of evaluating dynamic load increases that the vehicle transfers to the road pavement, due to the generation of vibration produced by surface irregularities.

The study starts from the generation, according to the ISO Standard, of different road roughness profiles characterized by different damage levels. In particular, the. In the case of vehicle-road interaction, the prediction of the dynamic axle loads can be uncoupled from the solution of the road-pavement interaction problem.

Many factors affecting the friction coefficient between tires and pavement surfaces have been found through laboratory and field investigations. These factors were related to vehicle and aircraft operation, to tire design, and to types of pavement surfaces.

The effect of these factors on the friction coefficients were varied. The interaction between vehicle and road surface is an extremely complicated dynamic process that involves vehicle dynamics, pavement structural mechanics, and frictional mechanics.

When a car travels on road surface, the roughness of road surface is transferred as displacement excitation via tires and suspension to car body and results in the.

Numerical simulation approach has recently grown in popularity due to its wide range of applications in the solving of random vehicle-pavement interaction (VPI).

This study proposes a framework to simulate the dynamic vehicle load process due to a quarter-truck vehicle model moving along a rough road surface. A procedure used to generate artificial time histories of dynamic vehicle. tire/pavement interaction that creates a pressure variation in air will create sound.

Acoustics is the science of sound and is the broad discipline of the study of the generation, propagation, and reception of sound in all aspects. Noise is defined as unwanted sound.

Sound Typically sound is created by a vibrating surface, in. Pavement response computed using dynamic models matches field measurements closer than those computed using static models. The concept of vehicle-pavement interaction can be applied to weigh-in-motion, pavement design and performance, and vehicle regulations.

Highway traffic noise is caused by tire-pavement interaction, aerodynamic sources (turbulent airflow around and partly through the vehicle), and the vehicle itself (the power-unit noise created by the engine, exhaust, or transmission).

At highway speeds, tire-pavement interaction generally is the most dominant source (Sand-berg and Ejsmont, ). Identification and mapping of asphalt surface deterioration by tyre-pavement interaction noise measurement fissures or potholes), induce acceleration of the vehicle and the friction between the tyre and the road is simultaneously An closely related issue with the highway asphalt surfaces is the Tyre–pavement interaction noise (TPIN).

Excessive water depth may cause the vehicle tires to hydroplane, i.e., the may become separated from the surface and between pavement surfaces and tires is very much dependent upon velocity to Forces arising from other contributing mechanisms or interactions at the tire­ pavement interface, as stated before, would be added to Equation.

A road is considered safe when it provides adequate friction between the tire and pavement surface interaction to avoid accidents.

The current manual methods of evaluating surface friction of roads are not only dangerous for the inspectors and motorists on the road but are very time-consuming and subject to the inspector’s judgment.between them [1].

Pavement surface friction is a measure of safety for driving on the road pavements and has a great role in reducing accidents especially in wet weather conditions [2]-[4]. An essential part of the vehicle-pavement interaction is friction force between the tire and the pavement surface.Interactions among rough pavements and heavy trucks, field and laboratory measurements, and computer simulations to predict the interaction forces are discussed as well.

This research is leading to a better understanding of the dynamic interactions between heavy trucks and pavements and the detrimental effects.
