The entire design of the road looks, in fact, like a pie, each layer of which performs its own functions. The upper layer provides a constant friction coefficient, thanks to it, good braking in the heat and cold is provided, reduces radial sliding in the bends. The upper layer, the so -called layer of wear, is a renewable coating that is updated on average once a year. The guaranteed service life of the entire roadway is about ten years, but the top layer must be constantly updated. The following lower layers already distribute the load among themselves, representing the waterproofing system.
