On the Dynamic Load Impact on the Roadway with Respect to Surface Irregularities

Many research results testify to a 2–3 times increase in the dynamic load on the structural elements of transportation structures compared to static loads, including road and bridge pavements due to surface irregularities. The load-slab interaction is identified for the road pavement taking into account surface irregularities. Purpose: The analysis of the vertical acceleration and vehicle speed effect on changes in dynamic characteristics. Research findings: Additional dynamic loads, stresses and deformations due to dynamic load from random traffic flow are identified for the bridge elements.
