The TRIMM project (acronym of Tomorrow’s Road Infrastructure Monitoring & Management) was completed late in 2014. It was funded under the European Union’s Seventh Framework Programme for research (FP7, 2007-2013). Its objective was to strengthen the role of condition monitoring in road management and to highlight its beneficial effects. The condition of a road network is, in fact, decisive for its level of service to road users. Maintenance is required to preserve or improve the condition of bridges and roads.
This project subsidized by the Belgian Bureau for Standardization NBN (1st October 2008 – 30th September 2012) was devoted to the development of performance tests for thin and ultra-thin asphalt layers (with a thickness ranging between 10 and 30 mm), which are increasingly used in Belgium and in other European countries. The research effort related directly to a priority set by European standardization committee CEN TC227/WG1, which intends to develop performance tests and performance specifications for all types of asphalt mixture, and to the finalization of ETAG 16, which describes European guidelines for ultra-thin layers. Several test sections (including those with low-noise surface courses on regional road N19 at Turnhout-Kasterlee) were monitored within this project, to validate the test methods.
