Highways Authorities Product Approval Scheme (HAPAS)
HAPAS was set up by the Highways Agency, CSS and The British Board of Agrement (BBA) to develop approval processes for products, materials and systems used in highways and associated areas. Various Specialist Groups were set up to study specific market areas and produce guidelines which would include details of testing procedures, assessment criteria and quality assurance requirements used in the evaluation process carried out by BBA.
BDWA sat on Specialist Group 7 which concentrated on bridge deck waterproofing in UK and fought vigorously for the raising of standards to appropriate levels for modern products and systems, particularly in performance trials and testing procedures. However, some significant revisions proposed by BDWA were ultimately not adopted due to a wish to be consistent with proposed harmonised European standards that aim, to some extent, to avoid removing low performance systems from the market. It is feared that a great opportunity to promote excellence in UK bridge deck waterproofing has been missed.
Members are now undertaking the work necessary for certification. It is anticipated that HAPAS will be implemented in 2010/11.
