In 1996 the Dutch Ministry of Transport, Public Works and Water Management launched the innovation program ‘Roads to the Future’. One of the developed innovative pavement structures is a Modular Pavement Structure called Modieslab. This structure is designed as a bridge and it merely consists of precast concrete elements. Since 2001 several researches were performed. Along the motorway A50 in the Netherlands a low-risk and not heavily loaded test section was constructed and monitored during 16 months. On this test section mainly the functional properties as well as construction and maintenance techniques were investigated. The main findings of this test section are reported. The structural integrity of the structure was investigated by Accelerated Load Testing of another instrumented test section by means of LINTRACK. Some characteristic measurement results are presented. Insight into the structural behaviour of both the total pavement structure and the most critical upper part of it was further obtained by means of 3D finite element modelling. Some typical calculation results are compared to measurement results. Finally the materials research is briefly described. This research concentrates on the porous concrete wearing course. Research is ongoing to find solutions for skid resistance and ravelling problems that occurred to some extent on the test sections. Given the rather positive experiences, both from a technical and an economical point of view, it was decided to actually construct an in-service road section of the radically innovative Modieslab pavement structure after only 4 to 5 years of research. Probably this project will be realized in 2005 or 2006 in an area with very poor subsoil.
