The present invention can be reused by mixing the components of the semi-rigid mixture consisting of the crushed and cut waste ascone, cement, filler, emulsifier at the optimum composition ratio through the environmental pollution problems caused by waste and recycling of resources A mobile recycling apparatus for waste asphalt and waste concrete capable of pursuing raw material supply and economic profit.

Roads are one of the important social indirect capitals and must be steadily established or continuously renovated. These roads are rapidly deteriorated due to the rapid increase in weight and weight of the vehicle, and a lot of waste asphalt is generated as the road is continuously constructed and repaired for high speed and increased lanes.

In addition, waste asphalt is inevitably generated during milling and crushing of roads during water and sewage and communication cable construction, as well as repair of the road itself.

In addition, as the population increase and the urban concentration of the population accelerates, the reconstruction of buildings is actively underway, and waste concrete will inevitably occur even when the buildings are demolished.

If such waste asphalt or waste concrete is left unattended, it will pollute the environment, so it will be immediately collected at the construction site and transported to the work site where the crushing device is installed, shredded to an appropriate size and disposed of in a landfill.

However, the landfill site is not only limited in the capacity of landfills, but also in the process of selecting landfill sites, the residents who live near the landfill candidates face problems such as civil complaints. It is following.

In addition, since the remaining resources such as crude oil and aggregate, which are the raw materials of asphalt, are limited in the future, they are depleted in the future, and the problem of recycling resources can prevent economic pollution and at the same time obtain economic benefits.

In particular, the recycling of waste materials can reduce the initial development cost of resources, and thus economical in terms of producing materials.

Therefore, if waste materials such as waste asphalt or waste concrete are recycled and used, they can overcome the environmental pollution problems caused by these waste materials and the difficulties associated with landfill site selection, as well as secure raw material production costs and aggregates for civil construction. The difficulty of having can be solved.

In this regard, as a device for reusing waste asphalt or waste concrete, "waste asphalt recycling apparatus" in Korean Utility Model Registration No. 191802 and "waste asphalt concrete recycling apparatus" in patent registration No. 412067 are known.

The former device can be mounted in a vehicle, and a plurality of rotating drums supported by a support roller to rotate with the power of a motor communicate with each other through a connecting plate including a burner, and the upper part of the rotating drum inlet side is closed into the rotating drum. A storage unit for storing asphalt fragments is installed, and a guide slope for guiding the waste asphalt fragments supplied from the storage unit into the rotary drum is installed at the inlet side of the rotary drum, and the waste asphalt fragments broken into a predetermined size are disposed in the rotary drum. It is input.

In the latter device, a hot air duct is installed at the distal end of the rotating drum which is composed of a single body, and a hot air duct is installed to prevent the flame of the burner from being directly transferred to the waste ascon, which is introduced into the inner part. Waste heat ducts are installed to guide the reuse of the wastewater, and the agitating means for discharging and discharging the recycled particles discharged through the discharge hole and the discharge hole through which the recycled ascon particles are discharged to the outside is provided at the lower end. By installing heat in the waste asphalt using indirect heat of the burner, it is possible to improve the risk of internal explosion and fire as the flame of burner is directly transmitted, and to improve the thermal efficiency by reusing the waste heat used for heating. Will be.

The above-mentioned conventional apparatus is a device for totally reusing waste asphalt, so that a burner device must be installed to impart cohesiveness to the waste asphalt, and thus the manufacturing cost is relatively high, and the waste asphalt is heated to about 150 to 180 ° C. As a result, harmful volatiles solidified in asphalt evaporate and carbon dioxide is generated, causing secondary air pollution, and concrete or soil generated at construction sites have to be treated separately.

In addition, the heat regeneration method uses heat in the regeneration process, and the use of energy is inevitable. As a result, the asphalt undergoes an oxidation reaction with oxygen in the air and loses its elasticity and hardens to exhibit sufficient strength. Therefore, the heating regeneration apparatus requires thorough temperature control from production to transportation and construction, and the production is extremely limited because such work management is not easy.

An alternative to solve the problems encountered in the heating regenerator for manufacturing road pavement is to mix the pavement mixture at room temperature with cement, polymer emulsifier and filler without heating the crushed or cut waste ascon. To manufacture. Most important here is the chemical function of the emulsifier. These emulsifiers determine the properties of the room temperature packaging mixture and further determine the strength and compatibility of the packaging material.

Therefore, the present invention can be moved quickly in the construction site in the regeneration of the waste asphalt, while eliminating the heating method for the collected waste asphalt and waste concrete, and the soil and aggregate, and toward the regeneration method at room temperature, emulsifiers and It can be mixed together at the optimal weight ratio so that it can be recycled as construction materials at the site, so that the costs of producing raw materials and construction aggregates, including the problems of environmental pollution caused by waste materials and landfill site selection, etc. The present invention seeks to provide a mobile recycling apparatus for waste asphalt and waste concrete.

The ultimate object of the present invention is to remove the waste asphalt and waste concrete, and the heating method for the soil and aggregate collected while being able to move quickly in the construction site, and aimed at the regeneration method at room temperature, as a construction material in the field By using the chemical and physical properties of the emulsifier to impart the cohesive power and excellent rigidity to the waste asphalt, waste concrete and soil and aggregates, it is possible to shorten the curing time in the construction using recycled products, cement packaging Waste asphalt and waste concrete to produce recycled road pavement that has the intermediate properties of cement pavement and asphalt pavement, which combines the rigidity and durability of asphalt pavement with the elasticity and flexibility of asphalt pavement. It is to provide a portable playback device.
