Objectives

High-quality concrete pavements are characterised by high quality workmanship and high durability over the entire service life. It has not yet been fully researched which parameters play the decisive role in achieving this. We therefore analyse all sub-process steps in the concrete pavement production and consider the effects on the finished roadwork.

The aim of the project is to optimise the process chain of concrete pavement production, which consists of numerous individual steps. We develop data-based decision criteria for support during construction. The necessary scientific foundations are laid to produce single- and double-layer concrete roadways with significantly higher construction quality in the future. We explore concrete technology measures to ensure the best possible durability and thus a long service life of the concrete roadway. In addition, we take into account technologies for noise reduction of the carriageway surfaces by producing them as exposed aggregate concrete or concrete with a low-noise surface. The evenness of the carriageway also has a decisive influence on driving comfort and durability. We accordingly include the current state of knowledge on the evaluated longitudinal profile and the recording and evaluation of evenness in 3D in the project.

Another goal is the reliable production of concrete pavements by using modern information and communication technology to monitor and evaluate the sub-processes of concrete pavement production during construction and to optimise and coordinate them by exerting influence as needed. The digitalisation and networking of all process steps is crucial in order to optimise not just a single production step, but the entire value chain.
