ROD-IS is a partner in this CEDR project which is funded under the CEDR Transnational Road Research Programme Call 2013 “Energy Efficiency”. The project commenced in April 2014 and is due for completion in March 2016. The project is developing a software tool to assess the impact of construction process quality on the performance of pavement surface course. Quality control during the construction process is, next to road design and material selection, an important factor that determines the performance of an asphalt road with respect to its service life. A tool will be created that will improve the quality of work during construction by improving the understanding of the risks involved in specific road construction circumstances and by identifying methods to manage these risks. The practical use of this tool as part of procurement procedures will be demonstrated in pilot projects and a guideline for implementation by national road authorities and road industry will be provided.
As part of the project, ROD-IS is responsible for collecting information about available quality control methods which can be used in the transport, laying and compaction of asphalt surface course. There are many recent technological advances (e.g. GPS monitoring and infrared temperature scanners) that have the potential to revolutionise the quality control of asphalt. ROD-IS has conducted a comprehensive desk study to gathered information on all types of quality control methods and has quantified their effect on the lifespan of the material. The information gathered is a critical input to the quality assessment tool which will quantify the effect of quality control on the construction parameters and hence the service life.
