The NZ Transport Agency has released a pilot version of the P25 Specification for Calcined Bauxite for trial and comment. We welcome your feedback.

This is a performance-based specification for calcined bauxite applied with non-bituminous binder on an appropriate substrate. The expectation is that...

• Reference: TNZ M/01
• Author: NZ Transport Agency

This specification and guidance notes set out the physical characteristics required to be met by all bitumen used in New Zealand. All of the products supplied as grades listed in Table 1 require approval by the NZTA, which includes the approval of a quality assurance plan for the manufacture and supply of an M/1 approved bitumen. Although only 5 grades are listed in Table 1, to avoid presenting...

This specification (2012) and guidance notes outline the process for identifying sites where treatment to improve skid resistance may be justified and the process to be followed. In addition, previous versions of the T10 specification (1997, 1998, 1999, 2002 and 2010) and notes (1997, 1998, 1999 and 2002) are listed as historical references.

This test procedure covers the determination of the average texture depth of a paved surface using sand to give the volume of voids. The method is suitable for the measurement of surfaces with average texture depths greater than 0.45 mm (less than 350 mm sand circle diameter).
