Highway Authorities Product Approval Scheme (HAPAS)
HAPAS was established to provide a nationally recognised approval scheme for innovative products and systems used in highway works.
Since 1995, HAPAS certificates and reports have provided highway engineers with invaluable data on product performance, design and installation for project planning.
For more information about HAPAS, please get in touch with a member of the BBA team using the details on the Contact Us page.
