“ I am in the field of pavement construction equipment.‘Enthusiast’，Likes good equipment，WittgenW 380 CRCold in-place recycling equipment，Compared to Wittgen's previousWR 2500 SCold recycling machine、WR Type 250 cold recycling machine，More comprehensive technical performance，And can meet that construction requirement of more working condition.！”

General Manager Tian said，W 380 CRCold in-place recycling equipment is a masterpiece of sophisticated technology in the industry.，It is also the indispensable main force of Dacheng Road and Bridge in the construction of cold recycling road in situ.，At the same time, it also represents the trend of future construction methods in the industry.。

Strong，Specialize in refining

As an expert、A scholarly boss，General Manager Tian has been with the company since its establishment in 2006.，Adhere to the line of specialized construction enterprises of pavement engineering，The company has the second-level qualification of general contracting for highway construction.，Class I of highway maintenance、Class II and Class A、Class B, Class II、Class III Grade A construction qualification，Three-level qualification of municipal general contracting，And roadbed、Qualifications such as professional contracting of pavement construction and construction labor services regardless of specialty，The company also has five asphalt mixing plant production bases.，The annual output of asphalt materials is more than 1 million tons.，The construction quality of Dacheng Road and Bridge is not only regarded as a benchmark by the industry.，It was also rated by the local government.“Honest enterprise”“Trustworthy quality unit”。

“Asphalt cold in-place recycling equipment construction plate，It is the biggest bright spot in the business of Dacheng Road and Bridge Company.。”General Manager Tian said，In 2021, the asphalt recycling construction area of Dacheng Road and Bridge reached 1 million square meters.，This year, the construction area of asphalt recycling has exceeded 900,000 square meters.，It is expected to exceed 1.3 million square meters in the whole year.。

  

Dacheng Road and Bridge has strong strength in asphalt cold recycling construction

What is the concept of 1.3 million square meters?？This is equivalent to a 10-meter-wide road paved by Dacheng Road Bridge this year.、The regeneration thickness is 10 cm，130 km road in length。This amount of construction，It is enough to make Dacheng Road and Bridge rank one of the best in the national asphalt cold recycling construction industry.。

  

Tangshan Dacheng Road and Bridge Company owns Wittgen、More than 50 sets of equipment of the three major brands of Fogler and Hummer

As Wittgen's“Loyal fans”，General Manager Tian has more than 50 pieces of Wittgen equipment, large and small.，Among them, there are more than 10 Wirtgen on-site cold recycling equipment.，Dacheng Road and Bridge in terms of construction scale of cold in-place recycling，Or the number of cold recycling equipment in place?，They are in the forefront of Hebei Province and even the whole country.。

 

Have a unique insight，Layout in advance

General Manager Tian said，Although the construction method of asphalt cold recycling in situ is now so popular all over the country.。Five or six years ago.，This construction method is still in the initial stage of experimental section in many parts of China.。Nowadays, the local cold recycling business of Dacheng Road and Bridge is continuous.，Thanks to General Manager Tian's long-term persistence and optimism.，It is precisely because Dacheng Road and Bridge has done a lot of construction promotion and technology accumulation before.，Only then did we have the joy of the present harvest.。

According to introduction，General Manager Tian as early as 20 years ago.，That is to say, around 2002, it was attracted by the construction technology of asphalt cold recycling in situ.，He has a unique insight，It is believed that this construction technology will be promising.。“2006，I bought Wittgen.WR 2000 recycling machine，At that time, there were not many users who dared to buy this in China.。”General Manager Tian said，With advanced Wittgen equipment，He dares to guarantee the construction period and quality to the owner.，And this equipment has also become the starting point of Dacheng Road and Bridge.“Meritorious service”Equipment。

“WittgenW 380 CRThe local cold recycling machine is a sophisticated one.‘Mobile mixing station’，Without the latest Wirtgen in-place cold recycling equipment，We can not realize the construction technology of cold recycling of foamed asphalt based on synchronous paving.。”General Manager Tian said，The construction process of asphalt cold in-place recycling is the first to have Wittgen equipment.，Only in this way can the construction technical specifications formulated by the Ministry of Transport in 2008 be established.，Wittgen promotes the development of recycling road maintenance and construction in China.，It has really made a significant contribution.。

Green emission reduction，The trend of the times

General Manager Tian said，Compared with the traditional construction method, the cold in-place recycling construction technology，It belongs to revolutionary subversion.，It can solve the problem of reflection crack of semi-rigid base.、And that construction cost is reduce、Prolong the service life of asphalt pavement、Ffective utilization of waste pavement material，Achieve the green emission reduction advocated by the state，New construction technology for energy saving and environmental protection。

Cold in-place recycling of asphalt pavement also has a unique advantage.，That is, construction can be carried out while traffic is open.，It can be opened to traffic on the day it is repaired.。“We are in Luanzhou，Using Wirtgen for Cold In-Place Recycling Construction，The owner's expectation is that we are in 2.-Finish the project in three months.，As a result, we renovated all four or five roads in Luanzhou City in just 20 days.，The markings and so on are all done.。”General Manager Tian said，Major in Dacheng Road and Bridge、Efficient construction performance，It has been highly affirmed by local government leaders and local people.。

  

Asphalt pavement cold in-place recycling construction occupies only one lane.，It can be opened to traffic while under construction

National Highway 112 was overhauled in 2017，Dacheng Road and Bridge is 12 meters wide with asphalt cold in-place recycling construction technology、24 km long project，Looking back on this project after many years，General Manager Tian said proudly.：“You go and see，Not a crack in the road.，The effect is very good，Stand the test of time.。This construction process can not only save 40%The cost of construction，It is also of great help to improve the quality of the overall road surface.。”

2019，Restoration Project of Dacheng Road and Bridge in Guye Outer Ring of Tangshan Heavy Traffic Road，It is also a construction process using Wittgen high-performance foam asphalt in-situ cold recycling equipment.。Look back at this road in three years.、Inspect the construction quality，You will also find that the restored roads have stood the test of time.，No transverse joints even under heavy traffic load。

“Special Semi-flexible Structure Mode of Cold Recycling Mixture with In-place Foamed Asphalt，Determines the low temperature sensitivity of the material，Compared with the traditional flexible base material, it has better high-temperature stability.， But also has good splitting strength.， Better fatigue resistance。”General Manager Tian said，As more and more people understand the unique advantages of cold recycling technology of foamed asphalt in place.，This construction technology will inevitably be more widely used in the future.。
