Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This thesis evaluates the impact of vehicle overloading on road pavement layers, focusing on the deterioration of pavement structures and its effect on the asset's life. The research uses a secondary source of data and applies the KENLAYER computer program for nonlinear analysis and determining critical responses on pavement layers. The analysis examines the damage ratio to assess premature failure, calculate the reduction in the road's service life, and evaluate the economic loss due to overloading.
