Abstract

The present invention relates to a road pavement that recycles waste ascon, which is an industrial waste that causes environmental pollution. Conventional pitched ascon (hereinafter referred to as "pitcher") is a flexible pavement coated by heating asphalt to aggregates. As the asphalt flows to fill the voids in the pavement, the effect of permeability is lost and the strength is also weak, and the effectiveness of the pavement is not achieved. The waste ascon pavement has many problems in durability due to high cost and plastic deformation due to asphalt heating.

The present invention prepared a road paving material by collecting waste ascon as a method for solving this problem by crushing to the aggregate No. 7 standard with a grinder.

The particle size specification of crushed waste ascon aggregate is 100% through 19mm sieve, 90-100% through 13mm sieve, 40-70% through 10mm sieve, 0-15% through 5mm sieve, and 0- 2.5mm sieve As a recycled aggregate consisting of 5% pass, the road paver using recycled aggregate of this standard is mixed with waste asphalt asphalt aggregate and asphalt emulsifier in the mixer in the first stage so that the asphalt emulsion can be sufficiently applied on the surface of waste asphalt concrete. In the second step, cement and admixture are put in a mixer to be mixed with the asphalt asphalt emulsifier-coated waste ascon aggregate, and in the third step, new aggregate, water, and organic additives are added to a water-soluble polymer in a pigment and a mixer. It is a packaging material formed by mixing sufficiently in

The pavement material formed as described above provides road pavement that recycles waste ascon which is durable even when used for the surface layer of roads and driveways through which light vehicles pass such as sidewalks, bicycle paths, promenades, parking lots, etc., and does not cause plastic deformation.

Description

Road paving with recycled waste ascone {omitted}

The present invention relates to a road pavement that recycled waste ascon. More specifically, asphalt emulsifier is applied to crushed waste ascon aggregate, and cement and admixture are mixed therein, and new aggregates, water, organic additives, pigments, etc. It relates to a road pavement formed by sufficiently mixing at room temperature.

In general, ascon is a pavement that combines asphalt and cement. It is a soft pavement. As a result, it has a weak lifespan and high maintenance costs. Therefore, there is a problem in economics. In the process of researching how to use ascone as recycled aggregate for road pavement, aged ascone was collected and pulverized by particle size, and it was used as pavement by adding new aggregate, modifier and filler while heating at Ascon plant. Since this method is also used to heat the waste ascon, plastic deformation occurs due to the decrease in penetration and elongation, which is a component of asphalt, and it is difficult to satisfy the economics at high cost for heating.

Therefore, in order to solve the problem of the waste ascon has been proposed a number of products that can be used as a basic aggregate of the road paving material.

For example, if you look at the patent claims described in the Republic of Korea Patent Publication (Publication No. 10-0243926, road paving concrete using crushed waste ascon and its manufacturing method), it passes 100% in 40mm, 95-100% in 25mm Based on the size of the granulated waste ascon (10) and the solid content 100%, which passes 25-60% in a 13mm sieve, 0-10% in a 5mm sieve, and 0-5% in a 2.5mm sieve. Mixing 5% emulsified asphalt so that the emulsified asphalt 20 is applied to the surface of the pulverized waste asphalt concrete 10; cement 30 to the pulverized waste asphalt asphalt 10 coated with emulsified asphalt 20 of the electrical process Mixing 250-500 kg / m 3; And 50 mm or less of sand or waste ascon which corresponds to 10-50% of the amount of crushed ascone in the pulverized waste ascon 10 in which the emulsified asphalt 20 and cement 30 of the electrical process are mixed. Coarse aggregate, water-cement ratio 20-50% water, 0.8% or less water-cementing agent is added to the mixing, mixing step to make the slump 0-10cm; including the method of manufacturing concrete for road paving However, the method of manufacturing concrete for road pavement using waste ascon is collected from waste ascon and crushed into aggregate No. 57 particle size standard and recycled as base and auxiliary base material of ascon pavement, but plastic deformation occurs in surface layer of ascon pavement. Turtles, etc. due to the phenomenon has not been able to suppress.

The present invention was devised to improve such a problem. The waste ascon, which is an industrial waste that causes environmental pollution, was crushed to the aggregate No. 7 particle size standard to sufficiently apply the asphalt emulsifier to the surface of the aggregate, and mixed cement and admixture with it. The purpose of the present invention is to provide an improved packaging material that is durable and free of plastic deformation as a recycled packaging material obtained by mixing so as to be easily combined with new aggregates, water, organic additives, and pigments.

In addition, the packaging formed by such a mixture is not a heating package but a room temperature package, so it is possible to reduce the high cost of heating the waste ascon, which is a great economic advantage. It is to prove that it is an environmentally friendly road paver that can prevent and obtain resources.

The present invention is a road pavement recycling waste ascon aggregate formed by mixing waste ascon aggregate, asphalt emulsifier, cement, admixture, new aggregate, water, organic additives, pigment, etc. It characterized in that it is formulated using less than 13mm recycled aggregates.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
