  • Conventionally, as a method for repairing such aged or deteriorated road pavement two types of surface treatment methods, mainly a mixed surface treatment method and a spray surface treatment method, have been proposed.
  • the mixed surface treatment method involves the asphalt mixture produced by mixing asphalt and aggregate at a plant, transporting the mixture to a construction site, and paving it on an aged or deteriorated road surface. This is a method of repairing cracks and cracks. Since the asphalt mixture is paved on the road surface, it is basically a rehabilitation of the pavement, and although it is a repair method, it is a surface treatment method that requires almost the same process as the ordinary pavement construction process. is there.

That is, in FIG. 31, after the road sweeper 102 is moved in the direction of the arrow to clean the road surface 101 to be subjected to the surface treatment, the asphalt distributor 110 3 , And asphalt as a binder is sprayed on the road surface 101. Subsequently, the truck 104 on which the aggregate is mounted inclines the carrier, and spreads the aggregate on the asphalt layer from the rear while traveling in the direction of the arrow, that is, the vehicle travels in reverse. This is to prevent the tire of the track 104 from stepping on the asphalt layer already scattered.
  • the asphalt layer at that portion adheres to the tyre of the truck and becomes thinner, which not only weakens the bonding force between the aggregate and the road surface but also reduces the traffic. This causes problems such as asphalt sticking to the tires of 1 104, and when the track travels on other roads as it is, marks of asphalt are left on the road surface. .

In addition, the asphalt layer where the aggregate was scattered was not desirable because it caused a slip of the vehicle and a flash phenomenon in summer. Due to these drawbacks, the spray-type surface treatment method has the advantage of being simple and relatively inexpensive, but at the same time lacks reliability and has not been used as a repair method so far.
