The second ring road of chengdu & other; Double quick & throughout; Reconstruction project east ring road viaduct construction, on Wednesday to the & other; Waterproof glass fiber & Steel Sheds;The constructionTest sectionThe constructionAt about 2 PM yesterday, the test section began pouring type asphalt concrete construction, it is also the first time on expressway viaduct began laying asphalt.
According to understand, test long 100 meters, 6 meters wide, laying will be carried out after the completion of more than 30 test, for steel box girder bridge deck asphalt paving technology ready to work, and large areas of the bridge deck asphalt paving will start arriving this month, plan laid east half ring viaduct road at the end of April.
Don't crush the asphalt concrete
2 PM in the afternoon, a mechanical noise coming from the second ring road construction road viaduct, a nearly 10 meters wide asphalt concrete paver is spread their temperature as high as 250 degrees Celsius in 6 meters wide on the test section.
Far standing next to the construction site, can feel the heat coming from the black asphalt concrete, & other; The casting type asphalt concrete with the ordinary, it is fluid, deserve to go up premixed macadam, after the shop can achieve smooth use effect, no roller compaction. Throughout the &; Construction units, chengdu huanchuan Ren Bo group deputy project manager is introduced, the technology originated from Germany, widely used in European countries, most of the pavement service life more than 20 years, has a waterproof, durability, good fatigue crack resistance and deformation ability, especially suitable for large spanThe steel structureBridge deck pavement.
Will do more than 30 test
& other; Now we just test section laid, then will do more than 30 test, including the detection of bridge deck pavement, asphalt and steel structure such as uf, for next step paving technology to prepare large area. Throughout the &; Ren Bo told reporters.
According to preliminary arrangement, on March 5, or so, the construction unit will pilot the first batch of steel box girder bridge deck asphalt paving, and then gradually large, plans to complete the entire eastern half ring viaduct bridge deck asphalt at the end of April.
It is understood that due to the casting type asphalt concrete material temperature is Steel Sheds http://www.jingtabuilding.com/steel-sheds.html, can use professional transport vehicles, can be heated on the way, raw material, ensure that lay at the scene when the temperature at 250 degrees Celsius.
