Jin Wu line expansion project is Jintan through Changzhou a fast channel, its east Wujin pole bridge, West to Jintan 240 provincial highway, nearly 19 km in length, urban rapid road, design speed of 100 km, with six lane main and subordinate second lane. Across the board all the way across the cross - interchange or under - crossing. After the completion of the vehicle can be a green light, Jintan to Changzhou from the original one hour to half an hour. As often the integration gold "road infrastructure westward engineering the core part, to expand the Changzhou city space radiation, promote Wu, gold economy across the social development is of great significance.
Road asphalt structure design as the main line 8 cm coarse grain type AC-25C modified asphalt concrete, 4 cm fine SMA-13C asphalt concrete. The grain type AC-20C modified asphalt concrete in the bridge deck is 6 cm, and 4 cm fine SMA-13C asphalt concrete. The total amount of the road branch company is about 330000 square meters, about 60000 square meters, the fine grained concrete about 450000 square, the total amount of about 110000 tons, accounting for more than half of the total amount of the project.
Because it is a semi enclosed construction, there are many difficulties in the construction of asphalt. The traffic and traffic control of the vehicle has caused a lot of trouble. Because of the asphalt mixture, the need to cool down to 50 to open the traffic, if the asphalt pavement temperature is higher than 50, there will be a vehicle to break into, will lead to asphalt mixture is stuck on the vehicle wheel, resulting in uneven surface of asphalt and damage. In view of this situation, the asphalt construction team every day to the construction section of the construction section of the detailed research field, the development of detailed traffic guide line plan, to ensure the normal construction and not affect the normal opening of the traffic. In the inevitable traffic fork, we take concentrated force to avoid the peak, grab the full asphalt, asphalt paving after timely watering cooling. Thus, a timely opening to traffic, avoid unnecessary traffic congestion. After a pavement is divided into all the staff of the company full hard, high-temperature, fighting heat, quality, safety, efficiently completed the this responsibility, for the city government to promote implementation of Jintan development decisions made a contribution.
