Structural Analysis of Polyurethane Bonded Aggregate on Block Revetments

For centuries dikes in the Netherlands have been protected against wave attack by revetments constructed of pitched blocks. Due to new insights into the behaviour of pitched blocks and increased hydraulic boundary conditions, a significant part of those dikes does not meet the current prescribed standards and safety norms anymore. As a result,...

Duurzaamheid van Elastocoast

In dit onderzoek is een voorzet gemaakt voor een sterktebeproeving van verouderd Elastocoast door middel van cilindrische proefstukken. Daarnaast is een vervolgevaluatie gemaakt van de proefvakken bij Petten en Zuidbout, alsmede een eerste evaluatie van het productievak Elastocoast bij Bath langs de Oosterschelde.

Development of a laboratory ageing method for bitumen in porous asphalt

Generally porous asphalt has lower durability than commonly used dense asphalt mixtures. Loss of aggregates from the pavement surface, called raveling, is the most common form of distress in porous asphalt. There are several factors that contribute to the accelerated failure or raveling of porous asphalt and among them ageing is believed to be...

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
