Tire pavement friction is the result of two main forces, adhesion and hysteresis. Adhesion is due to the molecular bonding between the tire and the pavement surface while hysteresis is the result of energy loss due to tire deformation.

As the tire comes into contact with the pavement, the surface texture causes deformation in the tire Size: KB. Mosher, L. Results from Studies of Highway Grooving and Texturing by Several State Highway Departments.

From the pavement viewpoint macrotexture or grooving is the source of interfacial drainage. Thus, maintaining adequate macrotexture augmented with grooving in crucial locations is the first step in providing a pavement with good traction characteristics.

A summary of 14 studies of pavement- grooving locations in the Los Angeles area is shown in Table 1. In the before period (1 to 3 years), there were wet-pavement accidents; in the after period (1 year or more up to 7), there were 76 wet-pavement accidents.

The model also was applied to evaluate the hydroplaning potential of different grooving designs used in practice and past studies and to explain the conflicting findings of past studies on whether longitudinal pavement grooving does improve traction and reduce hydroplaning risk.

Pavement grooving is a process where specially designed grooving machines equipped with cir¬cular diamond-tipped saw blades are used to saw discrete drainage channels into the pavement’s surface.

IGGA says case studies show that longitudinal diamond grooving can help improve vehicles’ traction where wet-pavement crashes have historically been a. Pavement grooving - transverse, primarily to drain water away quickly; longitudinal, primarily to give better traction on curves.

Pavement texturing by broom, burlap, or other means to provide a "rough" surface and hence, more friction and more skid resistance.

A road surface (British English), or pavement (American English), is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course.

How to Increase Traction on a Concrete Driveway. The usual procedure for ensuring good traction on a sloped driveway is "brooming," or making a series of light lines perpendicular to the slope in.

Purdue University’s Herrick Laboratories of West Lafayette, Ind., conducted research using its Tire Pavement Test Apparatus (TPTA), which can test nearly any pavement texture. The TPTA is a 38,lb., ft. diameter drum that allows the testing of multiple pavement textures and compositions with a range of tire designs.

Grooving. Grooving of PCC pavements provides a reservoir for surface water and can facilitate the removal of water if the grooves are placed parallel to the flow oath.

Parallel orientation is generally not practical because the flow on highway pavements is typically not transverse to the pavement. ADDITIONAL STUDIES On the basis of the work.

A semi-empirical model of the shear force properties of truck tires is used to illustrate the influences of tread groove depth, roadway skid number, and the mean texture depth of nt on the lateral and longitudinal forces generated by truck tires.

Improved pavement surface construction methods for new pavements and the use of pavement grooving and thin blankets for existing pavements are solutions to the wet pavement accident problem.

Before and after accident studies of pavement grooving projects indicate a reduction of 85% of the wet pavement accidents. Grooved pavement provides escape routes for water compressed between tire tread and pavement, and consequently, enhances braking and cornering.

"Last year the main runway at Langley Air Force Base in Hampton, Virginia, was transversely grooved. It has improved friction performance dramatically." Grooving also applies to highways.

These recommendations are based on a recent in-house study of the selection between flexible and rigid pavements with particular focus on local conditions.Grooving in asphalt and concrete is a great feature to prolong the life span of the pavement markings.

Century Fence uses groovers to create grooves in the road to prevent snow plows from scraping up the pavement markings and reducing the wear and tear of vehicles driving over the markings.The International Grooving & Grinding Association (IGGA) is a non-profit trade association founded in that represents the industry that performs grooving and grinding of both concrete and asphalt surfaces in addition to Concrete Pavement Restoration (CPR) and Concrete Pavement Preservation (CPP) methods.
