A Finite Element Investigation of the Superelevated Horizontal Curve
Abstract
Stress-strain analyses are studied under the bottom of the pavement
layer, and pavement life values are calculated depending on the cross-section
variation because of the superelevation in horizontal curves. For this purpose,
1st principal total mechanical strain values are analyzed with the
superelevation values changing between 0-8 (%) and the different positions of
wheel contact pressure. Finite element method is used for analysis. According
to results of the study, it is obtained that pavement life decreases with the
increasing superelevation, in the case of 8% superelevation and decreasing the
distance to pavement edge, pavement life decreasing gets to 34%.
