on April 30, the construction site of tj1 section of Maozhan expressway was crowded with people and roared with machinery
.
A full width paver distributed evenly in front of the road and cooperated with five rollers to roll and compact it repeatedly
.
The asphalt pavement was steaming with heat waves from time to time
.
After more than 4 hours of intensive operation, the paving of the first section of asphalt upper base test section was successfully completed, which opened the prelude of the whole line of asphalt pavement construction
.
The test section is 650m in length, 7.6m in width, 14cm in compacted thickness, and about 1900 tons of ATB-25 asphalt mixture is used
.
Previously, the project organized many special meetings and field visits to make scientific deployment and full preparation for the allocation of labor, materials and machinery
.
In the construction process, strictly control the mixing, transportation, paving, rolling and other links of asphalt mixture, follow the process principle of “high frequency, low amplitude, follow-up, slow compaction” to ensure the construction quality of asphalt pavement
.
Through field test, all indexes of the test section meet the design and specification requirements
.
The successful paving of the first section of asphalt pavement has laid a solid foundation for the subsequent large-scale construction and traffic conversion
.
At present, the soft foundation treatment, culvert, subgrade filling and bridge foundation construction of Guanzhu Linwu section of the project have been basically completed, and the prefabrication and installation of beam and slab, subgrade inspection and pavement engineering are steadily promoted; The Linwu Gaoyang section is under construction, including temporary construction, surface clearing, bridge pile foundation and culvert construction
.
The reconstruction and expansion project of Mao Zhan Expressway starts from Guanzhu, Dianbai District, Maoming City, passes by Dianbai, Maonan and Huazhou in Maoming City, Wuchuan, Lianjiang, Potou, Suixi and Mazhang in Zhanjiang City, and ends in Gaoyang, Mazhang District, with a total length of 108.59 km
.
It is reconstructed and expanded according to the standard of two-way 8-lane Expressway with a speed of 120 km / h
.
After the completion of the project, the traffic capacity and service level of the road section will be greatly improved, which will inject strong vitality into the economic development along the line, enhance the connection between western Guangdong and the Pearl River Delta, and promote the radiation effect of Guangdong, Hong Kong and Macao Bay area to further play
