Overview
Background & policy context:
In this project EP2, the behaviour of the water absorption of liquid applied waterproofing systems (FLK) will be investigated. The water absorption of FLK due to rain water, dew and air humidity will be simulated and determined with different storage situations. The influence of the water absorption on the interface bonding between FLK and mastic asphalt (GA) will be investigated using different tests in the laboratory and on bridges.
Objectives:
The main goal of the project is to study the water regime of liquid applied water proofing materials and to evaluate simple tests for the verification of suitability and for assessing the fitness of the system installation. The project will:
- investigate the influence of the water regime of liquid applied water proofing materials on the bond to asphalt layers
- evaluate the suitability of applied test methods for the examination and the assessment of the capability of the water proofing system
- evaluate the in situ use of the test methods
- propose requirement values (in the sense of the evaluation of the system suitability) based on determined characteristic values
