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.
