As the largest comprehensive games in Asia,，The 19th Asian Games will open in Hangzhou on September 23.。This is a game based on“Green、Intelligence、Thrifty、 Civilization ”A grand gathering of ideas.。

Road doctors as a part of the protection of the Hangzhou Asian Games，Always insist“Green Asian Games”The idea of，Renovation and upgrading of many roads for the Asian Games in Yuhang，These projects involve many important locations in the core area of Yuhang District.，Through the improvement of key roads、Subgrade and pavement facelift、Repair and reconstruction of inspection well, etc.，Display of environmentally friendly and beautiful urban roads，Give the surrounding citizens and athletes a new way to travel.。

Stone Bridge Road

“Suit the remedy to the case”，Boost the upgrade of the Asian Games

Shiqiao Road in Shangcheng District，It starts from Chitangmiao Road in the south，North to Qianjiahe Bridge，The total length is about 1820 meters.，56 meters wide，It is one of the key guarantee roads for the Asian Games.。As the main road of urban transportation，There are many vehicles passing by.“Tonnage”Big，Cracks often appear on the road surface.、Pothole、Rutting and other diseases，Especially at intersections.。

To stabilize the smoothness of the road，And that compression resistance of the road surface is improve，The road doctor specially tailored two for Shiqiao Road.“Prescription”。One is the use of asphalt reheat regeneration technology.，The pavement damage and other problems were upgraded in a large area.。Second, it is used at easily damaged intersections.“Semi-flexible”Surface layer reinforcement。

Judging from the current effect,，The semi-flexible surface layer has the advantages that the rigidity of the cement concrete pavement is high,、The bearing capacity is strong、Good anti-rutting performance and good flexibility of asphalt pavement、And that crack resistance is strong、Advantages of no seams，The goal of strengthening the compressive capacity of pavement has been achieved.。The intersections of Shiqiao Road, Desheng Road and Wen'er Road belong to this kind of intersection.。

Shixiang East Road

Level the road，Escort the thoroughfare of the Asian Games

Shixiang East Road is an important section of the main urban area.，Total length 8.Seven kilometers，It is one of the main roads for heavy vehicles in Gongshu District.。

After years of use，Shixiang East Road was damaged to varying degrees.。“Road doctor”After the road patrol，Adopt“Thermal regeneration”Technology，The fast lane of Shixiang East Road was comprehensively renovated.。Ying Da“International leading”Thermal regeneration technology，No dust during construction、No noise、Traffic interference is small、Fast construction speed，It can easily meet the high quality index requirements of municipal road maintenance.，It uses low-carbon and environmentally friendly clean energy.，Meet the requirements of green environmental protection of Hangzhou Asian Games。

In order not to affect the traffic.，Asphalt pavement renovation starts at 10 o'clock every night.。After six nights of work.，All the damaged sections of Shixiang East Road Expressway have been repaired.，The flatness and beauty are greatly improved.。

Wen'er West Road

Focus on four new technologies，Help upgrade road maintenance

As one of the east-west core roads of the future science and technology city，Wen'er West Road connects the beltway and Jingchang Avenue.，As a result, the intersection of Wener West Road and Jingchang Avenue is congested all the year round.，Especially in the morning and evening rush hours.。

The road doctor tested Wen'er West Road.，The road was found to have interlayer voids.、Loose、Diseases such as poor interlayer bonding，The disease of bus lane is more serious.，Road doctor uses hot in-place recycling technology to crack the pavement.、Inspection well、Diseases such as bus lanes have been disposed of centrally.。

Hot recycling technology is mainly used for pothole repair of asphalt pavement.、Area asphalt network crack、Maintenance of road asphalt diseases such as rutting，Its arrival has subverted the traditional asphalt repair mode.，It is environmentally friendly、Traffic interference is small、Do not disturb the people、High construction speed and the like.，It greatly improves the work efficiency and the level of fine chemical maintenance and management.。

Repair of manhole cover

Build“A glass of water will not overflow.”The traffic environment

Manhole cover settlement、Cave-in due to damage、Dislocation across the blind road，Became“A stumbling block”……All kinds of problems have brought a lot of security risks.。

To build“A glass of water will not overflow.”The traffic environment，Highway Doctor Successfully Uses Asphalt on Some Roads in West Lake District“Thermal regeneration”Technology to fix the manhole cover problem，The selection of interlayer thermal bonding technology can effectively improve the water sealing performance and shear strength of pavement，And that durability is strong。This technology takes less time to repair.、Good effect of road smoothness，It does not affect the normal traffic.。

Repairing manhole cover with asphalt thermal regeneration technology，Let the smooth and beautiful urban roads become a beautiful scenic line of urban civilization.，Convenient travel for residents has brought a strong guarantee.。

Next step，Hangzhou will continue to go all out for the Asian Games。Road doctors will continue to play an advantage.，And take this as an opportunity.，Demonstrate their own strength and level in the field of road maintenance，It also provides reference for more urban construction projects in the future.。
