Interaction between an asphalt revetment and the sand subsoil under wave attacks: Medium scale experiments with old and new asphalt concrete

Nowadays, in the Netherlands there are about 600 kilometers of asphaltic revetments lying mainly on sea dikes of which approximately 400 km of dike is covered with asphalt concrete [STOWA, 2011]. Asphalt concrete revetments are applied the most and are mostly of older age. Because of the older age it needs intensive care involving periodic...

Hydraulic performance, wave loading and response of Elastocoast revetments and their foundation - a large scale model study -

ELASTOCOAST revetments are highly porous structures made of crushed stones which are durably and elastically bonded by Polyurethane (PU). To improve the understanding of the physical processes involved in the wave-structure-foundation interaction and to develop prediction formulae for both hydraulic performance and wave loading more than 75...

Analysis of wave impact on the elastocoast system

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...

Wave impact on asphaltic concrete revetments: Literature review

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...

Experiment analysis: The relation between wave loading and resulting strain in an asphaltic concrete

Shock pressure interactions on prototype sea dykes caused by breaking waves

This paper deals with shock pressure phenomena due to breaking waves acting on sloping faces of sea dykes and other dike revetments. The full-scale investigations were carried out in the new research facility LARGE WAVE CHANNEL in Hannover. Germany. Maximum shock pressure estimations are given for practical slopes 1:4 and 1:6. An extension of...
