Description

Self-travelling apparatus for repairing potholes with using quick hardening type asphalt}

The present invention relates to a device for repairing a pothole of a pavement, and more particularly, to rapidly repairing a pothole on a road surface by repairing a porthole formed on a surface of a road while repairing a pothole formed on a road by using a fast diameter porthole repairing material by magnetic force. It relates to a repair device.

The present invention also relates to a fast curing pothole repair material which is particularly suitably used in the pothole quick repair device of the present invention by having a property of curing in a short time.

As time passes on roads paved with pavement such as asphalt, some of the pavement layers fall off, and so-called 'potholes' occur, or cracks appear on the road surface. Occurs.

Since such portholes cause an accident, repairs are usually made by repackaging the portholes or the parts where the cracks are formed, or by filling the portholes or the cracks with a repair material.

In general, the porthole repair work consists of patching the defective part and local resurfacing. This repair work is usually done by cutting and crushing the area around the porthole to a size, removing the debris, and then spraying oil (asphalt) into the porthole. Subsequently, after the ascon is applied into the pothole, the pothole maintenance work is completed by flattening and compacting (see Patent Document 1).

However, such repair work involves many individual equipment, such as a transport vehicle for transporting ascon, a cleaning vehicle for cleaning contaminants on the pavement, a spray vehicle for spraying oil on the porthole, and a compactor for flattening and compacting. Work is done by moving together, and each work process takes a lot of manpower, and the repair material takes a long time to cure, requiring a long working time as a whole. In addition, there is a problem that obstructs the traffic flow around the road for a long time during the road surface repair work, such as to control the traffic of the road for such paving work.

On the other hand, in order to solve the disadvantages or problems with the conventional road resurfacing method, as disclosed in Patent Document 2 below, a partial port repair method for resurfacing ascon after cleaning only the crushing hole during some road repair is proposed have. This method has a disadvantage in that the maintenance period is not long because the stiffness of the repaired part is weak, and thus the maintenance cycle is short.

The water retaining material O is filled in the port hole 3. Here, the pothole repair material refers to a mixture of the aggregate and the emulsion in an appropriate ratio.

The emulsion is a kind of binder that binds the aggregate, and is hardened after a certain period of time. Therefore, the emulsion must be mixed just before filling the aggregate into the pothole 3. In addition, the aggregates and the emulsion must be uniformly mixed to increase the bonding strength of the aggregates. In the present invention, an emulsion is used that is dispersed together with finely ground asphalt particles and oil in water.

In addition, the repairing apparatus of the present invention performs the porthole repair work while traveling slowly on the road where the porthole 3 is generated. To this end, the stored aggregate (M) of the aggregate storage hopper 20 provided in the vehicle body 10 is discharged through the discharge port 21, the lower conveyance extending from the discharge port 21 to the rear end of the vehicle body 11 Tube 31, a rear vertical feed tube 32 extending upward from the end of the lower transfer pipe 31, located at the rear of the vehicle body 11 to the rear upper end of the vehicle body 11, and the rear vertical feed tube 32. ) Is mixed with the oil while sequentially passing through the upper transfer pipe 33 extending in the longitudinal direction from the upper end of the vehicle body 11 to the front upper end, and then discharged from the discharge port 30 toward the road surface via the front transfer pipe 34. .

The compaction plate operation cylinder 62 operates by tapping the compaction plate 63 coupled to the lower surface while receiving pressure oil from the hydraulic pump P mounted on the vehicle body 11 and expanding and contracting (FIG. 5). . This compaction operation is performed in the state which stopped the vehicle which was running when the compaction mechanism 60 of the vehicle is located above the porthole 3 in which the repair material was filled, after filling the pothole 3 with a maintenance material.

As described in detail above, the porthole rapid repair device 10 of the present invention has the following advantages over the conventional road repair work device.

It is possible to continuously carry out the work of filling the port hole 3 of the road surface with the repair material while traveling slowly on the road, and the work of compacting the repair material filled in the port hole 3 without stopping the vehicle, thereby increasing the efficiency of the repair work. And road traffic control for repairs can be reduced to a minimum.

On the other hand, the repairing material used for the above-mentioned porthole rapid repair apparatus of this invention is demonstrated. The porthole rapid repair apparatus 10 of the present invention rapidly repairs the porthole 3 formed on the road surface 2 while traveling on the pavement 1, and thus, the porthole rapid repair apparatus 10 of the present invention is adapted to such working characteristics. ), Also used as a quick curing repair material.

The rapid-curing pothole repairing material according to the present invention is composed of an aggregate and an emulsion. The aggregate is not particularly limited as long as it is used for packaging, but particulate materials such as gravel, sand, gravel, steel slag, and the like may be used. Aggregate is composed of aggregates having a particle size of not less than 0.075 mm and not more than 2.36 mm, and not more than 0 parts by weight and less than 10 parts by weight of aggregate, and particles of not less than 90 parts by weight but not more than 100 parts by weight of a particle diameter of not less than 2.36 mm and not more than 4.75 mm The total sum of aggregates having a particle size of 0.075 mm to 2.36 mm and a grain size of 2.36 mm to 4.75 mm is 100 parts by weight.

The emulsion is an active hydrogen compound polyester polyols, polyether polyols, polycarbonate polyols, polyesteramide polyols, polycaprolactone polyester polyols, polybutadiene polyols, castor polyols, low molecular weight diols, Trimethylol propane, glycerin, sorbitol, mannitol, and the like. Castor-based polyols and castor oil-modified polyester polyols are particularly preferred, and castor oil-modified polyester polyols are most preferred.

In addition, the pothole repairing material of the present invention contains 8 to 13 parts by weight of an emulsion based on 100 parts by weight of the aggregate. The emulsion consists of a phase in which asphalt particles pulverized into fine particles are dispersed in oil. If the oil agent is less than 8 parts by weight, the bonding strength of the aggregate is lowered, and the wear resistance and strength of the cured product of the repair material are lowered. On the other hand, if the asphalt content is more than 13 parts by weight, the viscosity is increased and the strength of the cured product of the repair material is lowered. The emulsion may also include any modifiers.

According to this repair material, since the repair work is completed only by compacting after filling the repair material in the damaged part, it is possible to work with a minimum of manpower and a small work machine. As a result, the work process is small, which shortens the construction period and reduces the impact on traffic. In addition, since the water-retaining material is mixed at room temperature and hardening starts, temperature control is unnecessary as in the case of heating asphalt.
