Unbound paving blocks and slabs
Factors influencing shear resistance
We repeatedly see vertical and horizontal shearing in particular on more heavily frequented and more heavily loaded block pavements, which frequently results in damage to the paving blocks and impairs the serviceability of the paved surfaces. Whilst vertical shearing is in most cases caused by a lack of stability of the base layer and bedding, horizontal shearing is influenced to a much higher degree by the concrete block pavement. For this reason, comparative tests were carried out in the laboratory as part of product developments, and various influencing parameters were examined in greater...
