Wikipedia
profilograph
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 0.5 millimetres (0.020 in), macrotexture with wavelengths from 0.5 millimetres (0.020 in) to 50 millimetres (2.0 in) and megatexture with wavelengths from 50 millimetres (2.0 in) to 500 millimetres (20 in).

Profilograph
The profilograph is a device used to measure pavement surface roughness. In the early 20th century, Profilographs were low speed rolling devices. Today many Profilographs are advanced high speed systems with a laserbased height sensor in combination with an inertial system that creates a large scale reference plane. It is used by construction crews or certified consultants to measure the roughness of in-service road networks, as well as before and after milling off ridges and paving overlays. Modern profilographs are fully computerized instruments. The data collected by a profilograph is used to calculate the International Roughness Index, which is expressed in units of inches/mile or mm/m. IRI values range from 0 upwards to several hundred in/mile. The IRI value is used for road management to monitor road safety and quality issues. Many road profilographs are also measuring the pavements cross slope, curvature, longitudinal gradient and rutting. Some profilographs take digital photos or videos while profiling the road. Most profilographs also record the position, using GPS technology. Yet another common measurement option is cracks. Some profilograph systems include a ground penetrating radar, used to record asphalt layer thickness.
