Improvements in road construction, higher durability resulting from design solutions carefully selected to better cater for the thoroughly explored ground and subsoil conditions, more effective verification of exploration methods and studies used in road construction and, last but not least, new guidelines for subsoil research addressing the needs of road construction – these are the key outcomes of intensive research and analytical work which AGH UST researchers have conducted for a couple of years as part of the research project called ‘Developments in Road Innovations - Modern methods of subsoil exploration in road construction’.

The project was launched by ‘OT1-1E/PIG-AGH-PW’ Research Consortium, comprising – alongside AGH UST as a partner - Polish Geological Institute,  Polish Research Institute (leader) and Warsaw University of Technology (partner). 

On the part of the AGH University of Science and Technology, three faculties: Faculty of Geology, Geophysics and Environmental Protection, Faculty of Mining and Geoengineering and Faculty of Mining Geodesy and Environmental Engineering are involved in conducting the research work. Łukasz Ortyl, DSc. of the Department of  Engineering Surveying and Civil Engineering coordinates the project for AGH UST.

In order to meet the project objectives, the researchers working on the project as members of the research consortium have carried out detailed studies of over several hundred documents (including norms, laws, instructions and guidelines), set up several test sites, described over 230 research methods, performed 55 drills and over 100 geotechnical probing tests complete with several hundred geophysical, geodetic and remote sensing, point and surface measurements. Laboratory studies included 839 physical, 41 mechanical and 57 strain parameters. 

Researchers from the Faculty of Mining Geodesy and Environmental Engineering were responsible for the application of geodetic and remote sensing measurement methods and techniques as well as for the development of spatial reference systems and implementation of GIS solutions. On the other hand, scientists representing the Faculty of Geology, Geophysics and Environmental Protection supervised the application of geophysical methods and measurement techniques. They were also involved in monitoring work to be used as a ‘tool’ for verifying the behaviour of ground and geotechnical constructions at the exploration/design stage. Both faculties co-operated closely on ground monitoring for bridge constructions. The team from the Faculty of Mining and Geoengineering conducted monitoring work for mining sites and tunnels. In addition, they assessed stability of escarpments and slopes and developed methods to be used in exploration and assessment of the properties of rock masses, UPS application, hydraulically stabilised ground and aggregates.  

Developments in Road Innovations (RID) - the programme under which the research project ‘Modern methods of subsoil exploration in road construction’ was launched – aims to provide support for research and developmental work in road construction. The programme was set up as a joint initiative by the National Centre for Research and Development (NCBiR) and the General Directorate for National Roads and Motorways (GDDKiA).
