Description of the Related Art Scatter-type surface treatment is a method of repairing a road surface in which bituminous materials such as asphalt emulsion and cutback asphalt are sprayed on the road surface, and then aggregates of the same particle size, which is a concrete example of crushed single particle size, are sprayed and compacted. Is. Rolled asphalt pavement is made of asphalt mixture with a thickness of 25-50mm
It is laid on the ground, and the above pre-coated aggregate is sprinkled and press-fitted onto it. Conventionally, in these construction methods, aggregates are sprayed manually or by a chip spreader. There are disc rotating type and rotary feeder type in the spreader of chip spreader. The disk rotating type has blades attached to the disk, and the aggregate is blown by the rotation of the disk. In the rotary feeder type, the roll is provided with blades or grooves, and the aggregate filled in between the blades or between the grooves is scattered by the rotation of the roll. The amount of aggregate spread is adjusted by the traveling speed of the chip spreader, the rotational speed of the disk or roll, and the gate opening of the aggregate hopper. The aggregates dispersed by such a method fall freely, hit the road surface, and bounce off, and are irregularly arranged and overlapped. Since the aggregates that are overlaid are not fixed to the lower surface, after the traffic is released, the automobiles fly and are deposited on the shoulders and central part of the road. For this reason, cleaning must be done frequently after the opening of traffic. Flying stones can also break the windshield of a car. Further, since the aggregates are not arranged in a line, the appearance is not good, and there is a problem that the noise due to the passage of the tire is large.

A tamper 4 is provided in front of the aggregate dropping position of the rotary feeder 2, and a diaphragm 3 is provided behind it. Tampa 4
Is installed so that it reciprocates diagonally backward. Tampa
It is preferable that the angle of the bottom surface of No. 4 is approximately 30 ° perpendicular to the road surface. It is preferable that the gap between the tamper 4 and the diaphragm 3 be several mm wider than the maximum size of the aggregate. The stroke length of the tamper 4 is preferably about 3 to 12 mm, and the bottom dead center of the tamper 4 is preferably about several mm above the road surface. Further, the tamper 4 makes a stroke about 2 to 3 times while the vehicle moves forward by the average particle diameter of the aggregate.

上に配置される。FIG. 3 is an explanatory view showing a third aspect of the method of the present invention. Vehicle aggregate hopper 1, provided vibration feeder 3 'under the aggregate hopper 1. A vibrating feeder 3 'direction of travel opposite the vibration plate 3 (trough) from the aggregate hopper 1, arranged so that the gentle slope to the road surface.
Between the lower end and the road surface of the vibration feeder 3 'is preferably drilled several mm so as not to contact. The aggregate hopper 1 is provided with a gate 5 for adjusting the amount of aggregate supply. The aggregate conveying amount (kg / min) and the conveying speed (m / min) are the vibration frequency and amplitude of the vibrating feeder 3 ′ , the opening of the gate 5 and the vibrating plate 3.
The angle can be adjusted. It is desirable to measure beforehand the amount and speed of the aggregate to be conveyed according to the frequency and amplitude of the vibrating feeder, the opening of the gate, and the angle of the diaphragm 3 . Aggregate is put into the aggregate hopper 1, and according to the construction speed (m / min) and the aggregate placement amount (kg / m 2 ), the frequency and amplitude of the vibrating feeder 3 ′ , the opening of the gate 5 , the diaphragm 3 Set the angle of. At this time, the aggregate placement amount is adjusted so that the aggregates do not overlap. While the vehicle is traveling at a constant speed, the vibrating feeder 3 ′ feeds the aggregate toward the road surface in the direction opposite to the traveling direction of the vehicle at the same speed as the vehicle speed. Aggregate while being aligned by the vibration on the vibrating plate 3 of the vibration feeder 3 'are sent towards the road surface, it falls on the road surface. Since the aggregate does not exert an inertial force in the direction parallel to the road surface, it does not roll after falling on the road surface. Also, since it slides at a gentle angle, it does not bounce on the road surface. Therefore, the aggregates are arranged on the road surface in a state of being aligned with the diaphragm 3 of the vibrating feeder 3 ' .

Since the aggregate that is not fixed to the road surface by the bituminous material is eliminated, the scattering of the aggregate is greatly reduced. No cleaning work is required after the release of traffic. Since the conventional spraying type surface treatment cannot uniformly spread the aggregates, the aggregates are sprayed in an amount more than necessary to remove flying stones after the traffic is opened. On the other hand, the method of the present invention requires a minimum amount of aggregate, saves resources, and contributes to cost reduction.
