Slob, E.C. (author)This report discusses possibilities of using radar technology in asphalt pavement investigations in several types of pavement. The main focus is on highly porous asphalt (OSA) and watertight asphalt concrete (WAB), as used in Dutch seawalls. The determinations of layer thickness as well as layer integrity are important goals. The asphalt...report 2006

Gu, D. (author), Verhagen, H.J. (author), Van de Ven, M. (author)PUR-revetment is a newly developed method for hydraulic application. Its structure is similar to that of open stone asphalt revetment, but the crushed stones are glued by polyurethane (PUR) instead of bitumen. To study the feasibility of applying PUR-revetment, a research based on the comparisons between PUR-revetment and open stone asphalt...journal article 2008

Peters, D.J. (author)Het project betreft het beproeven van teenconstructies met een horizontale kracht. De gedachte daarbij is dat deze kracht de belasting representeert die de bekleding uitoefent op de teenconstructie indien deze naar beneden glijdt en tegen de teen gaat rusten. Er zijn twee locaties beproefd. Op één locatie bestaat de teenconstructie uit een rij...report 2008

Piontkowitz, T. (author)A large number of the dikes in the North Sea and Baltic Sea regions are covered with grass that is exposed to hydraulic loading from waves and currents during storm surges. During previous storm surges the grass cover layers often showed large strength and remained undamaged. A clear physical understanding of the failure of grass cover layers...report 2009

Bijlsma, E. (author)From 2004 to 2007 several pilot tests with an Elastocoast revetment were constructed along the North-Sea islands in the most northern part of Germany. In 2007 Elastocoast was introduced to the Dutch market. Arcadis supervised the construction and monitoring of two prototype pilots in the Netherlands. (September 2007) Revetment on a rudimentary...report 2009
