| description | The invention discloses a safe and environment-friendly asphalt mixture for repairing pits in pavement in severe cold areas and a preparation method thereof, the safe and environment-friendly asphalt mixture comprises cold patch asphalt and aggregate, and the mass ratio of the cold patch asphalt to the aggregate is 4.4-4.9%. The cold patch asphalt is prepared from the following components in parts by mass: 2 to 2.5 parts of road petroleum asphalt, 2 to 2.5 parts of low-volatility low-pour-point rubber oil, 0.3 to 0.6 part of TPO (thermoplastic polyolefin) thermoplastic elastomer, 0.1 to 0.3 part of light-cured resin and 0.001 to 0.01 part of photoinitiator. The safe and environment-friendly asphalt mixture for repairing the pit slot in the pavement in the severe cold region, provided by the invention, is good in construction workability and high in strength after being cured, can fully meet the requirement of treating the pit slot disease of the pavement in the cold region, does not contain diesel oil, is goo |
