Connected Construction

Geophysical Survey Systems (GSSI), a manufacturer of ground penetrating radar (GPR) equipment, has launched a more affordable version of its non-destructive system, called RoadScan 30. The system is designed for measuring pavement thickness, conducting base and sub-base evaluations and measuring available asphalt prior to milling operations. Hundreds of miles of pavement layer thickness data can be collected in a day. RoadScan 30 can collect data densities not obtainable using coring or other labour-i

Researchers at Nottingham Trent University in the UK are developing smart scanning technology using existing cameras to detect early signs of pothole development The technology scans roads for ravelling - the loss of aggregates from the asphalt which leads to potholes and cracks. Combined with 2D and 3D scanners on a pavement monitoring vehicle, a computer vision algorithm can examine the road with accuracy at traffic speed during day or night. The system works by detecting different textures of th

The use of machine control technology on a bypass construction job has boosted quality quality control is a topic that clients as well as contractors are finding increasingly important. Control systems are being used more and more often on construction sites as a result, so as to collect data on a range of processes. This includes looking at the asphalt being supplied to site and on the quality of paving during construction. Using this data, processes can be optimised in the medium-term and, in the long-ter
