HAPAS (Highway Authorities Product Approval Scheme) was set up in 1995 to establish a nationally recognised approval scheme for innovative products and systems used in highway works.
Successful HAPAS assessment results in the issue of a Certificate or Report which provides highway engineers with product performance, design and installation data invaluable to the product choice and project planning processes.
