Product Description

Driveway seam repairing sealant asphalt sealant 
road crack repair asphalt sealant joint sealing machine

Product introduction

LLRD-G80 Crack Sealing Machine is used for sealing joints in the cement roads. 

The equipment is composed of melting box, heating system, control system, transporting system, crack-oriented system, moving system, power system and so on.

It is used for sealing joints in the cement roads. Thermostat control system heats hot melt materials and can prevent aging materials effectively. Pressure injection sealing provides complete results by filling the gap from the bottom.

Machine Parts

Name:  Generator

Brand: Yamaha 

Original: Japan 

The machine adopts imported Yamaha generator

Rated Power: 2.0 kw
Voltage: 220 v

Main Features

Hot melt kettle uses thermal oil heating which has uniform heating and sealant is not easy to carbide in the kettle

Temperature monitoring system

 LED digital display temperature control system, can monitor and adjust the temperature of the heat conduction oil and the temperature of the electric heating tube 

External feeding pump: 

greatly simplifies the equipment maintenance procedures and improves the service life of the machine

Electric heating tube:

3 m in length. Applying the electric heating tube could smooth the process of glue pushing. The electric heating tube uses plastic Teflon as inner core, the outside of inner core is winded by heating wire, to ensure the maximum stretch and the highest heat transfer. It has multi-layer insulation; Outer is asbestos and heat pipe is yellow

Electric Igniter

Machine Parts

Humanized sealing spout scraper, is more efficient in operation, reduce the labor intensity of workers, and is equipped with a drip discharge valve, completely eradicate the road pollution

Special mobile trailer: 

Optional choice, making movement more easy and convenient.

Construction Procedure:

1.Prep the Crack with either a router or random crack saw. This opens up the crack, creates a reservoir and preps the edge for better bonding. Rout or Saw? The most common approach is Saw Concrete, Rout Asphalt.

2.Clean the crack with dry, clean compressed air or for the best results, use a Heat lance. A heat lance removes not only dirt but moisture and vegetation. The heat lance also heats the old surface which helps in bonding with the new sealant. THE CLEANING PROCESS IS THE MOST IMPORTANT PART OF THE PROCESS.

3. Seal the crack with a quality Polymer modified brand name rubberized hot-pour sealant. Hot-pour sealant is proven to last up to 10 times longer the cold applied products in flexible pavements.

Product Features:

1. Thermostat control system can set up and control heating temperature automatically without easy aging, so that the material maintains a constant temperature. 

2. Material pump and pipe are equipped with heating device, avoiding material condensation at low-temperature environment effectively. 

3. Pressure injection sealing provides waterproof effect by filling the gap from bottom through material pump.

4. When seeling speed and walking speed are adjusted in line, the equipment will be able to move by itself with hand push and achieve the effect of intelligent construction. 

Note: Equipment configuration can be adjusted according to customers construction needs.
