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.
