Over de stad en de kleine korrel: Collectieve architectuur tussen ideaal en praktijk

What do collective dwellings contribute – or could they contribute – to the city? To answer this question we will start with the 2006 publication The intermediate size: a handbook for collective dwellings, and compare the assumptions in this study and that of the Hooidrift construction project in Rotterdam, which was completed in 2017. The...

Polyurethane bonded aggregate revetments design manual

In this manual design rules and guidelines for the design of Polyurethane Bonded Aggregate revetments (PBA-revetments) are presented, based on results from laboratory research, full scale model tests, and experience and field measurements. Research is still ongoing, but from the first results some insight into the structural behaviour of PBA can...

Elastocoast pilots in the Netherlands: 2008-2009 extended monitoring

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...

The Elastocoast® system: A study of possible failure mechanisms

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...

Elastocoast pilots in the Netherlands, storm season 2007/2008

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...

Alternative designs for hurricane protection systems and building structures in New Orleans

First the demands and the boundary conditions are set for the complete protection system; after that the protection system will be split in the three subsections (primary: peripheral levees, secondary: canal levees and watermanagement and tertiary: structural integrety housing). For each of these protection systems an analysis will be made; this...
