Further crushing of the material (homogenization + reprofiling) to a depth of 250 mm – the resulting mixture is 0/45 mm.

In the next phase, the structural layer will be recycled in accordance with ČSN 73 6147 with cold technology on site, layer thickness 250 mm - the resulting recycled mixture according to ČSN 73 6147 will be RS 0/45 CA (before the actual recycling on site, it is necessary to verify the physical and mechanical properties of the future recycled mixture - the processing of proof tests) A base layer of asphalt mixture of the ACP asphalt concrete type will be laid on the treated surface 16+ in a thickness of 70 mm with a 50/70 asphalt binder and, after applying the bonding spray, an abrasive layer of asphalt mixture type ACO 11 + in a thickness of 50 mm with an asphalt binder 50/70. As part of the construction, the existing shoulders will be torn down in the entire section, ditches will be cleaned and new shoulders of 50 cm width will be established from asphalt r-material fraction 0/22, at the same time direction posts will also be installed. All connections of new asphalt surfaces will be cut and covered with asphalt grout.
