Roads

Sustainable construction needs to be in accordance with the long-term preservation of the environment for humans and other living beings, both today and in the future. Activities that lead to sustainability include the construction as well as maintenance of high quality roads which will be able to cope with both increased traffic loads and climate change. On the other hand, it is necessary to perform such construction works in such a way that the least possible damage is caused to the environment. By monitoring road conditions and applying appropriate maintenance measures the impact of transport on the environment can be reduced. Before construction or maintenance works can be performed, appropriate subsoil investigations have to be carried out, as well as making sure that material to be installed is of sufficiently high quality. Only in this way will roads be durable and stable, with the minimal amount of maintenance works. Sustainable thinking clearly includes the reuse and recycling of industrial and construction waste. ZAG’s activities in this field are therefore the following:

• geological and geomechanical subsoil investigations,
• performance of special subsoil investigative tests (the cyclic triaxial test),
• third party quality control of materials for the construction of pavements and sub-base structures,
• third party quality control of materials for the construction of pavements and sub-base structures,
• organization of test fields constructed with recycled materials,
• organization of test fields constructed with recycled materials,
• measurements of the skid resistance and macro-texture of pavement surfaces,
• measurements of the unevenness of pavement surfaces (in both the longitudinal and transverse direction),
• third party quality control and monitoring of geotechnical anchors,
• measurements of the vibrations of buildings and engineering structures,
• noise protection.
