    Using a movable bituminous material finisher with a precompression and smoothing board and a tamping strip in front of it, it has formerly not been possible to achieve the necessary degree of compression of at least 98% required for high performance road surfaces. It was therefore necessary to drive rollers behind the finisher, which had to roll each surface unit 10 or even more times. The object of the invention is to create a bituminous material finisher with which a degree of compression of 98% can be achieved, so that subsequent rolling is no longer necessary. This is achieved by a compression element located behind the precompression and smoothing board, which bears down continuously on the surface of the precompressed bituminous material and is connected to an expansive force drive, with which pressure pulses may be directed downwards into the bituminous material without lifting the compression element. The drive for this compression element is expediently mechanical or hydraulic.

    This invention relates to road construction.
    The purpose of the invention is to reduce the energy intensity of compaction processes.
    FIG. 1 schematically depicts a self-propelled road paver of bituminous mixtures, a common id; in fig 2, mounted on a pivoting cantilever frame of a device for preliminary and subsequent compaction; in fig. 3 - section aa on figo 2; in FIG 4, view B in FIG. 3; in fig. 5 is the same in the case of a generator of a vertically-sharply directed pulsing from (silt pulses in the form of a power phishndra; Fig. 6 is a hydraulic circuit.
    The self-propelled bituminous pavement paver consists of: 1 of the base machine, on the frame 2 of which the receiving bunker 3, the distribution screw 4 and connected with it by means of a rotary cantilever 5 with a drive 6 vertical movements of the preliminary 7 and subsequent 8 compaction devices “Before the pre-compaction device 7, a protective screen 9 is fixed, and the device itself is formed by a tamping bar 10 with a bevel 11 on the front part connected by rods with eccentrics, eccentric drive shaft 12, installed stationary in poddipnik 13,
    A smoothing vibrating plate 14 is placed behind the tamping bar 10. Behind the screeding plate 14 of the pre-compaction device 7 is placed a follow-up compaction device 8 in the form of a pressing bar 15 with a bevel 16 with vertical rods 17 installed on it, which are mounted in prestressed compression springs 18 and 18 passed through the holes 20 formed in the pressure bar 19, the latter being supported on the compression helical springs 18, and the upper ends of the vertical rods 17 are placed in the guide bars The brackets 21 attached to the smoothing vibrating plate 14 of the pre-compaction device 7. The clamping bar 19 is mounted on connecting rods 22 mounted on eccentrics 23 of an eccentric drive shaft 24 provided with unbalanced masses 25. A pressing strip 15 is placed between vertical guides 26 fixed to the smoothing shaking plates 14 and 27, respectively, of the preliminary compactor 7 and the subsequent compacting device 8, and suspended by means of springs 28 to brackets of a vertical guide 26 attached to the screed vibrating plate 14.
    In the case of a generator of vertical pulsating power pulses in the form of power cylinders
    29 last mounted on the brackets 21, and their pistons
    30 are made vertical
    the top of the ends of the rods 17,
    The power cylinders 29 are connected by pipes 31 through a control fixture 32 to a pressure source (not shown).
    Control device 32 is made with a rotary valve 33, rotated from hydraulic motor 34. Pressure is supplied to control device 32 through conduit 35 connected at the outlet of branch valve 36 with hydraulic accumulator 37. Valve 36 is connected to source of SPEAKER through outlet of branch valve 36. pressure (not shown), and through pipe 39 - with a hydraulic motor 34 "
    The speed of the hydraulic motor 34 and therefore the rotational speed of the rotary valve 33 is controlled with the throttle 40. The control device 32 is connected to the pipe 42 of the reservoir (not shown) via the pipe 41, and the hydraulic engine 34 is connected to the pipe 43. 32 is connected to a drain pipe 44.
    Self-propelled paving of bituminous mixtures “works as follows.
    After the bituminous mixture is loaded into the receiving bin 3, it is distributed by the screw 4 on the road bed in front of the tamping bar 10, which pre-compresses with shock the laid bituminous mixture 45, which is then smoothed by the smoothing vibrating plate 14. Then the pressing bar 15 of the device 8 is then compacted The final compaction of the bituminous mixture 45, while the pressing bar 15, in the process of influencing the latter, does not detach from its surface, and the final finish at the surface, then carried out.
