Modified binders should<br />
have a BBA HAPAS<br />
Roads and Bridges<br />
Certificate. In the event<br />
that no such<br />
Certificates have been<br />
issued, then in the<br />
interim, only modified<br />
binders undergoing<br />
BBA assessment<br />
should be considered<br />
for approval by the<br />
Project Manager.<br />
