摘要

Bridges are critical elements for infrastructure projects. Bitumen based state of the art systems cannot fulfil the increasing requirements for modern bridges when it comes to minimum service life and resistance to severe stresses, so developing new resin based systems which can provide a longer service life, shorter down times in case of maintenance works and reduced repair costs are the main target for system manufacturers. New spray-applied solutions offer rapid application and curing, and form a tough, elastic and seamless waterproofing layer. The key element is the increased tensile bond (> 0.4 N/mm～2) and shear strength to the asphalt overlay, which is substantially higher compared with traditional bitumen tack coats. The worldwide recognised standards for liquid applied waterproofing systems on concrete bridge decks are BBA/HAPAS and ETAG 033.
