Airport runway is the most special in asphalt pavement.，More than 100 tons of aircraft take off and land at a speed of up to 300km/h，Every take-off and landing，It is a great test for the runway.。Any pavement defect may lead to serious flight accidents.，Therefore, CAAC has very strict management and technical standards for runway maintenance.。

And the maintenance of the asphalt pavement of the airport，It is even more difficult：Frequent takeoffs and landings of 100-ton aircraft，Heavy rutting and high channelization，It has brought great challenges to the restoration work.；Without affecting the normal operation of flights，The effective maintenance construction time is only a few hours when the ship is suspended at night.；At the same time，Different from ordinary pavement maintenance，Skid resistance of airport pavement construction、Seal the water、Flatness、Material dynamic stability and other quality indicators have extremely high requirements.，Any index is not up to standard.，It may affect the service life and flight safety of the runway.！

Dealing with special materials for airport runways、Road sickness，The road doctor prescribed the right medicine，Use INTECH“International leading”Hot in-place recycling technology，Collocation and optimization process、High-end smart devices，Successfully forNanjing Lukou International Airport、Wuxi Shuofang International Airport、Chengdu Shuangliu International Airport、Chongqing Jiangbei International Airport、Shenyang Taoxian International Airport、Changsha Huanghua International Airport、Zhengzhou Xinzheng International Airport、Zhanjiang Wuchuan AirportAnd many other domestic airports for maintenance and treatment.。“Road doctor”Is the world's only highway that can simultaneously、National and provincial trunk lines、Thermal recycling equipment and technology for municipal road and airport runway construction！

Recently，Ying Da came to Changzhou again.，Successful repair of wheel ruts for the runway of Changzhou Benniu Airport、Pockmarked surface、Cracks and other road diseases。This is another masterpiece of Yingda in the field of airport pavement maintenance.。

 

 

Changzhou Benniu International Airport is 4EClass I International Military-Civil Airport，It is an important carrier for Changzhou to speed up the construction of modern comprehensive transportation system.。The reconstruction and expansion project of Changzhou Benniu International Airport is one of the key projects to build the central axis hub of the Yangtze River Delta.，The project will handle 4.9 million passengers in 2030.、The airport terminal area will be reconstructed and expanded with a cargo throughput of 120,000 tons.。Among，The total area of the expanded terminal building is about 3.10,000 square meters；Create a new freight depot 1.90,000 square meters、Comprehensive parking building 2.40,000 square meters。

Make use of every opportunity，Show the speed of Yingda！

Mall single construction area for airport pavement maintenance，Large area construction is not possible，And the time in which construction can be carried out is too short，Generally only 3-Five hours(Relevant regulations：Airport pavement support construction must not affect flight operation)，Therefore, the construction of the unit、The transition speed is extremely high.。

INTECH Thermal Regeneration Units have superior flexibility，Construction、The transition speed is fast，It takes only 30 minutes to complete the entry and exit.；Modular combination of equipment，Integrated construction，Construction speed up to 4-6 meters/Minute，Effective use of available construction time，Achieve efficient construction！

Suit the remedy to the case，Now Yingda Quality！

Different from common pavement disease，The airport pavement diseases are concentrated in the area where the rear wheels of the aircraft act on both sides of the double yellow line.，After a long period of use，A wheel rut appears、Crack、Material running、Pothole、Asphalt aging, etc，One of the most serious diseases is rut.。

Intech Suits the Medicine to the Case and Selects the Process、Equipped with equipment，Rutting treatment by hot in-place recycling process with interlaminar thermal bonding，Bonding the old and new pavement into a whole，Absence of weak joints and weak interfaces；

 

And then update through the device、Enhance its function by means of transformation, etc.，Accurate on site for asphalt mixture of original pavement、Add anti-rutting agent evenly，Optimize the original pavement gradation and asphalt-aggregate ratio，Reduce the void fraction，Improving Rutting Resistance of Recycled Asphalt Mixtur，Prolong the service life of road。

Conclusion

Changzhou Benniu International Airport Runway Successfully Repaired，It proves once again that Yingda is facing the complex maintenance problems of airport runways.，With a mature、Excellent coping ability and excellent technical level。Future，Yingda Technology Group will continue to protect aviation safety，So that more airport runways can meet every aircraft take-off and landing in the best condition.！
