As a part of M-12 Project in Vladimir Region (1st stage of construction), a unique demonstration ground was created for the assessment of noise protection screens. The best technologies for production and installation of screens are to be applied on M-12 Highway.
Within the ground, it is planned to conduct a technical and economic assessment of the screens of each manufacturer in the life cycle, taking into account the indicators of ease of installation, durability, maintainability, capital and operating expenses. The following factors will be assessed: experience of the companies at other facilities, availability of documents on compliance with the requirements of regulatory and technical documentation.
The construction camp of Stroytransgaz JSC was chosen as an experimental site.
Currently, seven companies have placed screens that meet the conditions of STO AVTODOR 2.9-2014 “Recommendations for the design, construction and operation of acoustic screens on highways” (as amended on October 16, 2020, No. 279), which specifies the increased requirements for quality indicators, design features, and warranty obligations.
