Unstressed road slabs of type 1PZ0-18 are manufactured according to special working drawings. Road slabs of type 2PZ0-18 made of heavy concrete are designed for the construction of permanent and temporary roads with a design load of 30 and 10 tons. The dynamic coefficient is set to 1.2, and the base deformation modulus used for calculating slabs is 50 MPa for permanent roads and 25 MPa for temporary roads. Scope of application: • Permanent trails • Temporary roads
