Is CGSC permitted in Road types 0, 1 and 2?
Reinstatements in close graded surface course (CGSC) material to BS4987 are permitted in type 0, 1 and 2 roads where this material already exists. Section 6.4 outlines the permissible options.
The table A11.2 dealing with bitumen binder equivalence issued as an errata slip will need to be modified in due course to reflect the permitted use of CGSC.
