Influence of the Shear Forces on the Roundabout Carriageway

The circular roadways at roundabouts are exposed to special traffic loads due to cornering, namely friction and shear forces, and in smaller roundabouts (mini roundabouts), torsional stresses (turning of tires on the spot). Especially due to the high proportion of heavy traffic, damage to the asphalt pavement is often found, such as cracks, unevenness (indentations, ruts), etc. While driving through the roundabout, the thrust and friction forces act on the asphalt pavement of the roundabout throug
