What is concrete tining?

Tining refers to pulling a metal rake across the surface to create grooves in the pavement with a depth of between 3-5 mm (1/8 and 3/16 in.). The grooves are typically slightly deeper than the striations from drag texturing, as the spacing and depth of tine grooves can have an impact on tire-pavement noise.

What does textured pavement mean?

Pavement texture is often categorized by texture wavelengths (the length between physically repeating features). A pavement surface is often a combination of numerous wavelengths, ranging from microscopic (sub-millimeter) to long (several centimeters). Pavement texture is one driver behind this effect.

What is the primary purpose of tining highways?

Similar to grooving, the primary purpose of longitudinal tining is to increase water channeling below the tire. There are many polyester concrete bridge decks in service on the state highways today that have been tined longitudinally.

Why do they texture pavement?

In the case of concrete pavements, these surface textures are added during road construction to create friction and skid resistance, which are especially critical in wet weather.

How do you describe the texture of a road?

From top to bottom: macro-texture rough and micro-texture harsh; macro-texture rough and micro-texture polished; macro-texture smooth and micro-texture harsh; macrotexture smooth and micro-texture polished.

Is grooved pavement bad for tires?

B.S., Mundelein, Ill. -In most cases, paving companies resurface the roads fairly soon after milling off the top layer and creating the grooved surface you describe. So, any kind of excessive tire wear from the grooved surface should be negligible.

What is texture depth?

Texture depth is a measure of macrotexture and provides an indication of the overall roughness of the surface, which assists vehicle braking and the dispersal of water from the contact areas between the road and vehicle tyres.

Why is there textured pavement in Texas?

Officials say texturing the pavement will not only rejuvenate and improve the road’s surface, but that proper surface textures can also prevent vehicles from hydroplaning during wet weather. The interstate has seen several accidents during recent rainstorms.

What is micro texture of pavement?

Micro-texture is the skid resistance or the resulting frictional potential provided by the material interface of the vehicle tyre and the pavement surface during accelerating and braking and can be measured using methods such as the British pendulum test.
