An Introduction to Pavement Design in Seasonal Frost Conditions

COURSE NO: C04-029
An Introduction to Pavement Design in Seasonal Frost Conditions
Course Highlights

This online engineering PDH course provides introductory information about evaluation of soil conditions, selection of materials, and design methods for pavements in seasonal frost conditions. It presents criteria and procedures for the design and construction of pavements placed on subgrade or base course materials subject to seasonal frost action. The most prevalent modes of distress in pavements and their causes are listed.


The detrimental effects of frost action in subsurface materials are manifested by non-uniform heave of pavements during the winter and by loss of strength of affected soils during the ensuing thaw period. This is accompanied by a corresponding increase in damage accumulation and a more rapid rate of pavement deterioration during the period of weakening; other related detrimental effects of frost and low temperatures are possible loss of compaction, development of permanent roughness, restriction of drainage by the frozen strata, and cracking and deterioration of the pavement surface. Hazardous operating conditions, excessive maintenance, or pavement destruction may result.


This 4 PDH online course is intended for civil and geotechnical engineers and other design and construction professionals wanting to learn how to design rigid and flexible pavements where seasonal frost conditions exist.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about frost, soil and pavement terminology applicable to seasonal frost design conditions
  • Learning about bound bases and how they are employed in frost conditions
  • Knowing the definitions of frost-susceptible soils
  • Understanding how the design freezing index is determined and applied in design for seasonal frost
  • Knowing how to design to accommodate varved clays
  • Learning about the alternative methods of thickness design
  • Knowing how to determine and apply the air freezing index
  • Learning about the reduced subgrade strength design method
