Roading bitumens

Published: 2011
  • Also known as: M/1; M1
  • 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...

Texture by the sand circle method measurements

Published: 1981
  • Also known as: T/3; T3
  • Reference: TNZ T/03
  • Author: Transit NZ

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).
