The elastocoast system can be used as an armour layer on revetments. The bonding system exists of a mix of crushed stones and 2-component polyurethane. This bonding system creates bonding forces between the stones and an open (porous) structure can be obtained. Elastocoast is developed by Elastogran GmbH, a BASF subsidiary. The response of an...

Er zijn een aantal wrijvingsproeven uitgevoerd voor verschillende soorten van blokken en belastingsgevallen. De resultaten zijn vergeleken met wrijvingsproeven die in 2005 zijn uitgevoerd met Hydroblocks. De proeven zijn uitgevoerd in juli 2009 (in de hal van de Deltagoot).

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...

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...

In the year 1991 the Technical Advisory Commission (TAW-A4) ordered a full scale investigation on wave impacts on an asphaltic concrete revetment. The goal of the experiment was to gain insight into the mechanisms which would lead to failure, cracking of the revetment. Also the behaviour of the revetment after failure (residual strength) was...

A new construction method of Polyurethane (PUR)-bonded revetments has been tested successfully as stable breakwater constructions on various locations in Germany (“Hamburg Hallig”, “Holm Gröde”), as dike revetment in the Netherlands (breakwater revetment in Zuidbout and Petten), as shoreline protection in France (canal embankment near Le Havre),...

Het Onderzoeksprogramma Kennisleemtes Steenbekledingen heeft tot nu toe veel nieuwe kennis opgeleverd. Een van de manieren om deze kennis beschikbaar te stellen aan gebruikers is door middel van een gebruiksvriendelijk computerprogramma waarmee steenzettingen getoetst en ontworpen kunnen worden. In het onderhavige verslag is gedetailleerd...

Ingevolge de Wet op de Waterkering dienen steenzettingen op waterkeringen vijfjaarlijks getoetst te worden. In de praktijk kan aan veel steenzettingen geen definitief toetsoordeel toegekend worden wegens een gebrek aan wetenschappelijke kennis. In 2003 is daarom door de Dienst Weg- en Waterbouwkunde van Rijkswaterstaat het Onderzoeksprogramma...

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...

Steenzet2008 is een gecompliceerd programma waarin veel detailprocessen die relevant zijn voor de stabiliteit van steenzettingen zijn gekwantificeerd in formules. In het kader van het Onderzoeksprogramma Kennisleemtes Steenbekledingen is het aantal deelprocessen dat oorspronkelijk in het rekenmodel Steentoets 4.0 was opgenomen, fors uitgebreid....

In September 2007 two prototype pilot tests were constructed along the Dutch coast with an experimental, polymer based revetment. An area of 490 m2 was put on a dike slope in the Eastern-Scheldt basin, and another 385 m2 on the horizontal surface of a beach groyne near the Pettemer Zeewering along the North-Sea coast. The revetment consists of...

Elastocoast is a new type of revetment system for use as a cover layer on dikes. It consists of granular material (rocks), which is fixed together with a two-component polyurethane adhesive. In the Elastocoast system each individual rock is covered with a thin film of polyurethane. When the adhesive is cured, this film fixes the rocks together...

Materials used for urbanized coastal structures often create a hard substra te ready to be colonized. Elastocoast, a new coastal protection material made from stones and polyurethane, is such a material. This study examined the recovery and growth during the winter of 2007-2008 of the biological community on two dykes in the Netherlands which...

In Klein Breteler (2007) staat dat bij sommige proeven de golfhoogteoverschrijdingskromme van de inkomende golven niet correct lijkt. De golfhoogteoverschrijdingskromme laat een overmaat (Scheldegoot) of tekort (Deltagoot) aan zeer hoge inkomende golven zien. In het huidige document is gekeken naar beide situaties: proef P25 in de Deltagoot, en...

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...

Vetiver grass is a sustainable and innovative solution for the protection of banks. It is shown that Vetiver grass is able to establish a full-stop of bank erosion caused by rapid drawdown. Therefore it provides us with strong indications that it is highly suitable as an anti-erosion measure. A combination of cohesive soil and Vetiver grass...
