- •
Curl in concrete crossties is captured in both laboratory and field experimentation.
- •
Temperature gradient & center negative bending moment have an inverse relationship.
- •
Temperature-induced curl can significantly alter support conditions.
- •
Crosstie bending behavior is sensitive to changes in support conditions.
