3D texture measurements - visual method for determining the surface properties of road pavements
Low-noise road pavements are used as effective noise abatement measures in Switzerland. To determine the actual effect of low-noise road surfaces, G+P uses numerous measurement methods. While the most common measurement methods record the properties of road pavements acoustically (e.g. with microphones), 3D texture measurements can be used to measure and assess the visual properties of road pavements that are relevant for noise generation. G+P has been carrying out such 3D texture measurements with its own photogrammetry scanner since 2022.
