Legal evening news (reporters Chen Si) early this morning, was launched the biggest overhaul of Chang an avenue "dress" project, began paving the road. New pavement with high viscosity, high elastic bituminous material, driving would be more comfortable. Planned date completed September 30, is expected to complete ten days in advance.
In late June, initiated Nan Li Shi Lu Kou Chang ' an avenue to the Wukesong section of major repair works, this is the first overhaul of West Changan Street 12 years.
At present, the main pavement repair completion two-thirds. To keep the asphalt pavement full night belt it will be dismantled during the construction and pavement, "new oil". Large-area road modified asphalt to avoid traditional asphalt "hard winter and summer soft" drawback; transit road specifically rutting resistance of concrete is used, similar to the "powerful wrinkle cream".
This morning, reporter Nan Li Shi Lu to Xin XING Qiao road, overhaul launched the largest paving project. 6 paving machine on the South side of the main road a total of 5 lanes and paving, rear sized rolling mills more than more than 10 Taiwan boosted a magnificent scene.

Secret shop high highly resilient asphalt to reduce cracking
Chang an Street overhaul has always been an important occasion for the application of new pavement materials. In 1997, the East Changan Street overhaul focused on applied mastic crushed stone mixture, increase pavement durability; 2009 East Changan Street overhaul and focus on the application of the anti-rut technologies; and the overhaul of the domestic high viscosity modified asphalt pavement material with high elasticity and become a new bright spot.
Because directly below the Line 1 subway line is located in Chang an avenue, for security reasons, air defense considerations, bottom of the Chang an Street 80-100 of explosion-proof layer is built. 890 of last century was paved with asphalt pavement.
Relevant person in charge of public companies, the asphalt pavement before the whole out of the equation, and resurfacing of asphalt pavements. To ensure driving comfort, instead of always using the extract bitumen from the oil, instead of using Lake, that is directly extracted from the pitch Lake of.
For better adhesion of asphalt and concrete structure, overhaul has added a layer of "tape". A homemade high viscosity modified asphalt of high elastic, road works, this is the city's first large-scale use of domestic products. This material to two more failure to reduce pavement cracks and prevent a "two-tier", also plays a role.
