Research Report 051 Freeze-thaw effects in New Zealand pavements

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

The design of frost-resistant pavements are discussed.

Aspects of design include:

  • the effects of freezing and thawing on pavementsselection of frost-resistant basecourse materials, including methods for their assessment and the use of additive
  • increasing the thickness of basecourse in relation to depth of frost penetration
  • provision of subsurface drainage; control of traffic during thawing
  • use of geotextile composites; and the application of seal coats.
