The pavement around Harbin municipal government is ＂painted face＂： the temperature of more than 20 degrees insolates the caulking asphalt.
Cctv news(Reporter Li Wenxue) Since the beginning of summer, three roads around the Harbin municipal government have been sunburned to varying degrees, especially the World Trade Avenue, which is the main trunk road in Songbei District. For this situation that has never happened before, the Songbei District Urban Management Bureau said that it was found that the asphalt ductility was low, and the construction unit and supervision unit were punished and ordered to clean the contaminated cars and clothes free of charge.
Suntanned asphalt polluted the street.
On May 19th, the weather forecast showed that the highest temperature in Harbin was 27 degrees Celsius. At 13 o’clock, the reporter found on both sides of the World Trade Avenue that nearly a thousand cracks in the nearly 2-kilometer section of the road were sunburned, and after being crushed by cars, they became a black piece, distributed on the road, shining in the sun. From a distance, it looks like there are many places of water, emitting an unpleasant smell.
The tire was stuck with asphalt and stones.
Pedestrians feel sticky when passing through these sections, while vehicles make a continuous "click" sound when passing by. Bitumen tire tracks can be clearly seen on roads and sidewalks, and asphalt and stones are also stuck on the tires of vehicles parked nearby.
Songbei District, named after its location on the north bank of Songhua River, was established in 2004. It is an administrative development zone, a national-level ecological city, the core bearing area of the national "Harbin New District", the seat of Harbin Municipal Government, and a national-level high-tech zone — — Harbin High-tech Zone implements unified management.
On many main roads in this area, frost heaving, shrinkage and cracking of pavement caused by temperature can be seen everywhere. Cracks covered with asphalt, like newly healed "scars", do not match the appearance of the new area very well.
On May 29th, Dong Xuanli, the person in charge of roads and bridges in Songbei City Administration Bureau, said in an interview with CCTV reporter that due to the limited funds, they did not rip off the pavement resurfacing, but poured hot asphalt on the pavement cracks on May 8th, but on the second day of pouring, that is, on May 9th, the asphalt was sunburned, which appeared again on the 19th. "This has never happened before."
The reporter inquired that the highest temperature in Harbin on May 9 was only 21 degrees Celsius.
Pedestrians crossing the street should jump out of the place where the asphalt melts.
Footprints covered with asphalt on the sidewalk
Dong Xuanli said that during this period, the Urban Management Bureau received more than 40 complaints from the masses. In addition to the World Trade Avenue, it was also found that the caulking asphalt in Tianyuan Street and Tian Xiang Street also showed signs of melting and was run over by passing vehicles. They immediately asked the construction unit and supervision unit to stop the construction, take measures such as sprinkling water and embedding sand stones to treat the pavement, and sample the asphalt used in the construction for inspection.
The phenomenon of asphalt melting can be seen everywhere
The test results show that the ductility of this batch of asphalt is low, which leads to slow setting of asphalt and low melting point to pollute the pavement. Therefore, Songbei Urban Management Bureau decided to impose a fine of 4% of the project cost (more than 900,000 yuan) on Heilongjiang Yufeng Road and Bridge Construction Group Co., Ltd. and Heilongjiang Zhongwei Construction Engineering Supervision Co., Ltd.
At the same time, the Songbei Urban Management Bureau also ordered the construction unit to clean the defiled vehicles and clothes free of charge, and apologized for the inconvenience and influence caused by this incident to the general public.
"We asked the construction unit to change the supplier and re-inject the pavement cracks. We also monitor these roads at any time, and now there is no problem. " Dong Xuanli said.
However, the situation is not as optimistic as Dong Xuanli said.
Construction workers are spreading sand on the road.
On May 31st, the highest temperature in Harbin was 31 degrees Celsius. At 15 o’clock, the reporter visited the World Trade Avenue and found that the construction workers were sprinkling sand on the road surface, and the phenomenon of asphalt melting was still serious. Pedestrians needed to jump when crossing the street.
In the next few days, Harbin will have a high temperature of 37 degrees Celsius, and the ground temperature will be higher. I hope the relevant departments will really pay attention to this problem and effectively solve this travel problem.
