Subgrade Soil Susceptibility to Shrink/Swell and Frost Heave: Effects on Pavement Performance

(2024)

Expansive clay soils that are susceptible to shrink and swell and silty soils that are susceptible to frost heave are found in many parts of the United States. At these locations, these soils serve as the subgrade of the pavement structure.

NCHRP Research Report 1096: Subgrade Soil Susceptibility to Shrink/Swell and Frost Heave: Effects on Pavement Performance, from TRB's National Cooperative Highway Research Program, presents a state-of-the-art update to pavement design procedures to better reflect the influence of subgrade soils susceptible to shrink/swell and/or frost heave on pavement performance.

Supplemental to the report is a dataset of appendices with research information for each chapter of the report.
