The trial paving of the upper layer of asphalt in No.1 pavement Lot 1 was successful
. 
At 12:00 a.m
. 
on April 30, the trial paving of the upper layer of asphalt in No.1 pavement lot began, which also marks that the pavement construction of this bid section has entered the final sprint stage
. 
The test section is on the right side of K27 + 180-k26 + 580 mileage, with a total length of 600 meters, and more than 850 tons of asphalt are paved
. 
The top layer of asphalt pavement is a project with the highest quality requirements and the most stringent construction technology requirements
. 
In order to ensure the successful one-time paving of the test section of the upper layer of asphalt and achieve the expected effect, the first bid of pavement is planned carefully and organized reasonably, and actively communicated with Guihuang company and the resident office
.
Before the paving of the test section, the detailed technical and safety disclosure work was carried out on the mechanical equipment, mixing process, rolling process, paving temperature, transport vehicles, joint corner treatment, etc., and the quality, progress, coordination management and other work during the construction period were carefully arranged to ensure the smooth paving of the test section
.
The successful paving of the test section not only provides technical guarantee and on-site construction experience for the next large-scale construction of asphalt upper layer, but also lays a solid foundation for further speeding up the construction progress and smoothly realizing the traffic target（ (photo / Yang Xingxin) the bridge deck system of bid section 10 of subgrade 2 was completed
.
On April 29, the pavement and pouring of the last joint deck of Yansheng bridge on the right side of bid section 10 of subgrade were completed, marking the successful completion of the bridge deck system of this bid section
.
There are 11 bridges in the 10 bid section of subgrade, of which Yansheng bridge and Houhe bridge are widened bridges of wengma expressway, with the greatest safety risk and construction difficulty
.
During the construction period, we should not only ensure the safety of wengma expressway, but also ensure the quality and quantity of the project
.
In this regard, the management department carefully planned and kept close communication and cooperation with the three parties all the time
.
During the construction process, the company’s leaders, road administration, traffic police and wengma Expressway cooperated with the safety and technology departments of the project to provide in-depth guidance for many times, which provided a strong guarantee for the smooth completion of the bridge
.
In order to ensure the smooth completion of the project before the May Day holiday and resume the wengma Expressway on schedule, the management department of subgrade bid 10 planned and reversed the construction period in advance, and the on-site technical management personnel actively organized and promoted the construction progress to ensure the smooth completion of the widening bridge
.
The smooth completion of the bridge deck system construction of the whole line has accumulated valuable experience for the subsequent widening bridge construction and laid a solid foundation for the smooth completion（ Picture and text / Chen Jiale, Liu Gang).
