THE MOST MODERN TECHNOLOGY IS USED TO ENSURE THE QUALITY OF ROADS AND BRIDGES
In order to increase work productivity, reduce research costs and ensure the accuracy of road and bridge quality research, TKA purchased modern research equipment – a road georadar, a controlled longitudinal sliding device and a bridge monitoring system.
The metal plate used to calibrate the new generation GPR readings significantly reduces the number of cores taken, which makes it possible to break up the newly laid asphalt surface less. GPR will check the asphalt thickness in both wheel tracks in one pass. In this way, it will increase work productivity and reduce research costs in asphalt pavement quality control research.
In 2018, following a change in the rules for the installation of asphalt layers in the construction of automobile road surfaces, which provide for a new method of measuring the slip resistance index of the road surface, when the index values are determined by measuring at a speed of 60 km/h with a controlled slip device conforming to the standard CEN/TS 15901-14, there was a need to purchase the controlled longitudinal sliding device Via Friction. This device will not only make it possible to more precisely control the quality of the installed asphalt surfaces, but will also help to assess the slipperiness of the surface in emergency road sections.
The new bridge monitoring system is designed for accurate static and dynamic displacement monitoring of structures (bridges, buildings, columns, towers). With it, it is possible to perform dynamic monitoring of engineering structures at a high frequency (up to 400 Hz) and with an accuracy of less than 1.0 mm. The new system will reduce labor costs and expand the possibilities of testing bridges and viaducts by determining their bearing capacity and residual life. It is expected that this system will help to manage the condition quality of bridges and viaducts more effectively by choosing the most suitable repair or planning the required time for it. It is expected that the use of this system in monitoring the condition of bridges and viaducts will significantly reduce the costs of their repair and maintenance.
