Macrotexture is defined as texture ("bumps and dips") in a pavement with a wavelength (distance from "bump" to "bump) ranging from 0.5 mm to 50 mm.

Wet friction depends on the hardness of aggregate minerals exposed on the surface and their micro-texture* roughness. Also, for speeds over about 40 mph, pavement macro-texture* is necessary to prevent hydroplaning by helping water escape from the tire-pavement interface.

Pavement texture is broken into two components known as Macro and Micro texture. ... Micro-textures refer to the roughness of the surface of the pavement. It is the fine texture that occurs on chippings and other exposed parts of the surfacing. For concrete pavement this is usually the sand and fine aggregates present at...

A pavement surface is often a combination of numerous wavelengths, ranging form microscopic (sub-millimeter) to long (several cm). The categories for texture wavelengths include mega-texture (50 to 500 mm), macro-texture (0.5 to 50 mm), and micro-texture (< 0.5 mm). Smoothness is partly contributed to by mega-textures,

The value is established by subjecting the aggregate to a standard polishing process, and then testing the aggregate with the Portable Skid Resistance Tester to determine its PSV. The property that an aggregate possesses which gives it a good PSV is often referred to as its' MICRO-TEXTURE.
