The invention relates to the construction and road machinery building and can be used in the construction and repair of road and airfield: coatings and floors of constructed buildings. A working member is known for vibrating the protective layer of the pavement, including a surface vibrator with a platform, which is provided with electric heating elements in the form of separate sections t13. The disadvantages of this device are the dissipation of part of the heat in the metalwork, the low level of vibration impact on the material under consideration, and, as a result, the poor quality of the protective layer of the road surface. The closest to the proposed is a working body for vibrating the protective layer of the road surface, containing sections interconnected with the formation of a closed working surface, and magnetostrictive vibration exciters installed in the sections and connected to current collectors t23. The disadvantages of this device are the considerable power consumption of the compaction process, as well as the low quality of the protective layer being constructed. The purpose of the invention is to increase the quality of the surface layer of the pavement and reduce the energy intensity of the compaction process. This goal is achieved by that in the working body for vibrating the protective layer of the pavement, containing sections interconnected with the formation of a closed working surface, and magnetostrictive vibration exciters installed in the sections and connected with current collectors, each section is provided with a reflector of sound vibrations and thermal energy, and longitudinal the axis of the vibration exciter is parallel to its working surface, and the current collectors are in contact with the sections located in the lower part of the working member. In addition, the sec- tors are interconnected pivotally, and the lower branch of the tTx is mounted in the guides. Figure 1 shows the working device for vibrating the sealing of the protective layer of the road surface, side view; figure 2 - section aa in Fig .; Fig. 3 is a view of the working member with articulated joints; figure 4 - section bb In fig.Z. The working body for vibrating compaction of a roadway layer contains sections equipped with magnetostrictive vibration exciters 2 and interconnected to form a closed working surface 3 moving relative to axis 4 installed in bearings 5. Longitudinal axes 6 of vibration exciters 2 are parallel to the working surfaces of sections. The sections contain reflectors of 7 sound vibrations and thermal energy, directed to the periphery of the working body. Vibro-exciters contain current collectors 8 connected to a current lead 9 mounted on the axis 4, with which the current collectors of sections located in the lower part 10 of the working member contact. The distance ef from the longitudinal axes 6 of the vibration exciters 2 to the friction surface between the axis 4 and the bearings is 5-fold. The oscillating wave of the oscillations and the distance b between the axis 4 of the vibration exciter 2 and the working surface of the section is a multiple of a quarter of the oscillation wave. 7,

where is the wavelength of the oscillations, and pi p are divisible numbers.

In the working body with sections 1 connected by means of hinges 1}, the working surface of the lower branch is a tape, the lower branch of which is installed in the guides J 2,

The tool member is part of or is connected to the body as a trailer. The body provides movement of the working body along a distributed, compacted mix of the road surface. Sections 1 of the implement are successively one after another moving into the contact zone with the pavement mixture. In this area tokosyeniki. 8 comes into contact with the electrical power supply 9, exciters 2 turn on86055

They begin to emit acoustic and thermal energy. Reflectors 7 direct this energy in the direction of the compacted mixture. The combined effect of the thermal and acoustic energies of the vibration exciters and the static load of the working body provides the desired characteristics of the road protective layer 10: density, water and frost resistance, strength and durability. After the sections leave the zone of contact with the mixture, the exciters turn off automatically, reducing the energy intensity of the compaction process. When the hinge is connected to the section 1-1 and the speed of movement of the working body can be significantly increased, which leads to

20 performance. BB
