In patching repair by the method of local thermoregeneration the boundary between the regenerated area and the rest of the pavement is eliminated. A so-called bond is created, which eliminates the possibility of water penetration into the subgrade and prevents premature destruction of the repaired area.
The ambient temperature practically does not affect the technology of such repair and will not prevent the formation of a reliable bond throughout the depth of the repaired layer. During heating (about 7 minutes) the temperature of the repaired area will reach 150÷170oC
