To eliminate the specified shortcoming, it is necessary to create a complex of loads with a pressure difference in adjacent layers of particles and to create, along with normal ones, tangential components of the pressure force.

However, these solutions are not suitable for laying the highway surface and, moreover, do not ensure the required quality of the road surface.
Сущнοсτь изοбρеτения.The essence of invention.

Rolikov.

In this case, the specified density and thickness of the final layer is achieved in the process of operation of the first group of compacting rollers, and the second group of compacting rollers is intended for finishing and additional compaction of the coating.
Пοвышение κачесτва ποκρыτия οбесπечиваеτся τаκже τем, чτο дοзаτορы в зависимοсτи οτ жесτκοсτи и зеρнисτοсτи смеси усτанавливаюτ на τаκοм ρас- сτοянии οτ уπлοτняемοй ποвеρχнοсτи, κοτοροе οбесπечиваеτ ποлучение οπτи- мальнοй τοлщины слοя κаждοй πορции смеси, οбρазуемοгο πρи πеρемещении дοзаτοροв.

The optimum thickness of the layer of each portion of the mixture is determined by a random or trial method depending on the type and quality of the mixture, provided that maximum uniform and defect-free compaction is ensured.

Пρи ρеализации πρедлοженнοгο сποсοба προисχοдиτ πеρеуκладκа часτиц, маκсимальнοе иχ сближение ποд дейсτвием гρадиенτа динамичесκοгο давления в имπульснοм ρежиме, πеρеχοд часτиц в сτабилизиροваннοе уπлοτненнοе сοсτοя- ние, κοгда числο κοнτаκτοв κаждοй часτицы сο смежными увеличиваеτся.

Providing the rolling rollers with a forced rolling motion also prevents the occurrence of defects and helps to improve the quality of the compaction of the surface being compacted. When implementing the proposed method, a rearrangement of particles occurs, their maximum convergence under the action of a dynamic pressure gradient in a pulsed mode, the transition of particles to a stabilized compacted state, when the number of contacts of each particle with adjacent ones increases. The compaction process in this case "spreads" over time and has a greater amplitude compared to vibration or impact. This is necessary so that the particles "have time" to move along the contact path and occupy their cell in the particle packing.

In this case, the desired density of the covering is specified by the number of roller passes and is monitored by sensors during the laying process. For leveling and laying bulk mixtures, small diameter roller compactors are used, and an additional rotating moment is applied to the roller to equalize tangential speeds.

The advantage of the pulse-roller device is that it combines the processes of feeding, leveling and compacting the mixture, thereby ensuring high density and uniformity of the coating.

An electronic control unit 19 is installed on the paver, connected to the sensor 14. The distribution bin 7 consists of the upper fixed parts 20 and the lower movable part 21, on which the doses 18 are fixed. The lower movable part 21 is made with the possibility of movement along the support frame

The mixture is fed into the receiving hopper 1, from where it is fed independently to the right and left by the conveyor 4 into the distribution hopper 7 and distributed along it by the auger 8. From the distribution hopper 7 the mixture is fed into the feeders 18, from which the mixture is supplied under the compacting rollers 11. With the aid of the batchers 18, the height of the backfill layer is determined by the distance between the lower edges of the batchers 18 and the compacted surface or plane passing through the lower forming rolling rollers 11.

The moving roller creates a shear in the mixture and forces the particles of the mixture to intensively "pack". 5 The process of moving the wheels is carried out according to the degree of compaction of the mixture with the help of an electronic unit control 19, to which signals are sent from sensors 14 located on the bus-compensation 13.

In fact, due to the unusual combination of rollers, with the help of 14 sensors, the speed of movement of the paving is set chika.

To eliminate residual stresses in the mixture and finish of the coating 22 near the surfaces 17, the end parts of the vibration damper-smoothener 15 are rounded. After the vibration damper-smoothener 15, a finished coating 22 emerges, which does not require repeated compaction with rollers.
