With the sound of firecrackers, Baomao civil construction of the three targets of road paving work officially opened, spreading aircraft carriers ahead, a new BMW escort, two rubber wheels interspersed busy, the size of the Hummer broken behind. Spread the scene is bustling, mechanical operations in an orderly manner, like an aircraft carrier team as spectacular. June 15 is a new starting point for BMTJ-3 pavement work. The paving work of the test section of the ATB-30 lower layer was formally carried out. Baomao BMTJ-3 took the lead in adopting the domestic and international leading KDT2000″ spreading aircraft carrier “spreading equipment. Maximum spreading width up to 20 meters, maximum spreading thickness up to 36 cm, maximum spreading particle size 80 mm, with fully buried spiral secondary stirring anti-segregation, super thick spreading, large width spreading, large particle size spreading and other advanced levels, won 98 domestic and international patent technology, known as “spreading aircraft carrier” reputation. The maximum adjustable width of one side of the telescopic ironing plate is up to 2 meters, and the nickname “Transformers” has solved two difficult spreading problems for the Hong Kong-Zhuhai-Macao Bridge, and has also been recovered as “Hong Kong-Zhuhai-Macao Bridge number “.

For the best rolling effect, BMTJ-3 special combination of rolling machinery is carried out. Using four new BMW lattices BW203AD-4 double smooth roller for initial and final compaction, and two Xugong XP263S rubber roller for compaction. Finally, a Hummer CC524HF is used to collect the surface.

To ensure a successful spreading of the test section of the lower layer of the ATB-30 before the spreading work was carried out, the BMTJ-3 standard organized all the pavement technicians, paver operators, roller operators, mixing station operators, transport vehicle drivers and other related personnel to carry out the technical background. At the same time, the head of the northern region of CUHK, the head of Inner Mongolia and the equipment experts of CUHK participated in the whole course of the paving of the ATB-30 pavement test section, which laid a solid foundation for the paving of the pavement test section.

In the process of spreading, the personnel study the details, take timely measures to deal with the problems and achieve the effect of effective control. Through the joint efforts of all the personnel for 4 hours, the paving work of the test section of the ATB-30 layer has been successfully completed. Through the test and test, all the indexes can meet the requirements of design and specification. spreading effect was approved and praised by the pavement expert group. ATB-30 the lower test section spread successfully.

According to the working thought of “Four New Technologies “, the BMTJ-3 standard of the reconstruction and extension project of Baomao Expressway has been carried out with the principle of” energy saving, land saving, water saving, material saving and environmental protection “, and has responded positively to the call of the state.
