Concrete milling, paving & compaction

PipeHawk has used its sophisticated ground probing radar (GPR) technology to develop the e-Spott system for the highways sector. The e-Spott package has been designed and developed in collaboration with another GPR specialist, Utsi Electronics. This new system is said to provide a fast and reliable method of testing the total thickness of bound layers to the sub-base interface or the thickness of surface concrete. This system has advantages over traditional coring methods as there is no need to cause disrup

INO, a world-class centre of expertise in industrial applications for optics and photonics, offers its laser rut easurement system (LRMS), a transverse profiling device that detects and characterises pavement rutting. The organisation says LRMS can acquire full 4m width profiles of a highway lane at normal traffic speeds (up to 100km/hr), using two laser profilers that digitise transverse sections of the pavement.

In determining the mechanical strength of cement, the European Standard EN 196 prescribes both compressive and flexural tests, so when Italian company Tecnotest designed its current generation of cement testing machines, the aim was to obtain highly accurate results over the full scale despite the wide range involved by implementing a dual scale in a single test bay, using load cells as dynamometers.
