Tar Paver RBE

Road construction industry, , , , , ,

The “Tar Paver” is a machine designed to uniformly “pressure pour” hot organic binding materials that are based in tar for the construction of roads and for making road repairs.

Tar is known as a fragile, black friable pulp obtained from refinery waste that can be used as fuel, insulating material for electric cables, and for road construction/repairs.  Of the total weight of the distilled oil, anywhere from 10 to 45% of the oil can become tar.

Tar is considered to be most effective for use in road construction, roofing and construction bitumen due to its astringent properties and its overall chemical composition that includes paraffinic, naphthenic and aromatic hydrocarbons, asphaltenes, etc.

Tar Pavers are used in many different sectors of construction, but particularly they are used in road construction.  The Tar Paver is structured with a tank mounted on a truck or on the chassis for possible transport to and around a construction site.

The Tar Paver principally operates with a sprayer mechanism.  The Tar Paver is capable of applying large volumes because of the built-in junction rod.

The Tar Paver is used for spraying bitumen emulsion. This Tar Paver however, is not suitable for bitumen as this it is not designed to maintain the high temperature needed to keep the binder in the liquid state which needs to be between 180°C to 190°C/356°F to 374°F.

Demand for high-quality road construction products has stimulated the emergence of different Tar Paver models.  If their tanks are fixed in the back of a truck, then the bar is set on a hydraulic pantograph and remains on the tank during unloading.  If the paver is installed on a truck chassis, it is called an asphalt distributor.

The unit’s Storage Tanks have different capacities to enable them to adapt to the size and weight of the vehicle selected for transporting them.  GlobeCore’s Tar Paver RBE – bitumen emulsion sprayer has the flexibility to be fitted with tanks that have a fluid capacity of between 500 to 10,000 Liters.  The internal design of the tanks provides for heating and/or for maintaining the desired temperature of the bitumen emulsion with burners that use liquid petroleum gas or diesel for fuel.

The GlobeCore Tar Paver RBE model is equipped with  that are connected to and are proportionate to the pole of the internal combustion engines driving them.  The spraying of bitumen emulsion is performed ​​with rods classified according to their characteristics and functions.  They range from a simple rod with a system opening known as a collapsible type, to a more complex system of rods with the opening that is a sliding type with a hydraulic drive controlled from inside the cabin of the vehicle.  When the vehicle is in transit, the rod is folded and fixed with pins. The top rod is lifted by special hydraulic motors and with a hydraulic cylinder that works in a manual mode.  To control the temperature of bitumen emulsion inside the Tar Paver, the RBE models feature a temperature sensor that is connected to a gas heating system.

The rail pressure for spraying is increased to the desired pressure by a “Frokarola” bitumen pump equipped with a German engine.  The bitumen pump is rotated by a hydraulic motor which in turn starts the hydraulic pump.

Emulsion outflow depends on the performance of the bitumen pump. The volume of sprayed material by the Tar Paver RBE is 0.3 liters/m^2 at a speed of 3 km/hr.

GlobeCore Tar Paver RBE models are much more convenient to use.  This is due in part to the control capabilities of the pump, lifts and other core functions.  The control capabilities can be accessed from an external console that can be operated from the external remote control or installed in the cabin next to the driver.  An alternative design places a stationary system of controls in the cabin of the truck.  In any case, each unit is mounted to suit the individual preferences and requirements of the client.

Optional additions to the Paver Tar RBE are as follows:

  1. Water tanks made of hot galvanized steel with transfer pump and hydraulic emulsion recirculation system;
  2. “Ecological” cleaning system of dirty detergent (diesel fuel, etc.), thus avoiding the need to reset the contaminated liquid with consequent damage and environmental pollution;
  3. tanks for diesel fuel to refuel fixed installations;
  4. many other solutions to facilitate the work on site and accelerate and increase the profitability of your company.

Model UVB-10PK

Road construction industry, , , , ,

Bitumen emulsions are very popular among consumers of building materials. Ordinary and industrial consumers, construction companies, and road-building companies pay particular attention to them.  Something that brings tangible benefits cannot remain unnoticed.

Bitumen emulsion is made by mixing bitumen and water with special equipment while adding emulsifiers (usually chemical class products amines) and acids. There are both benefits and limitations when using bitumen.  It is also important that the water used in the mixture does not have excessive mineral salt levels.

Bitumen emulsions are classified according to three criteria: (1) the sign (+positive or -negative) of the electric charge of the pellets; (2) the decay rate; and (3) the weight and content of the bitumen base binder.

Bitumen emulsions are further divided by their concentration levels.  Depending on the intended application, bitumen emulsions can have the following levels of concentration: 50%; 55%; 60%; 65% and 69%.

The decay rates of emulsion are categorized as being rapid, medium, slow or ultra stable. According to the sign of the electrical charge of emulsion granules (+positive or -negative), they are either anionic or cationic.  The latter one is more widely used due to a stronger adhesion level to the stone materials of acid rock.  Having greater adhesion characteristics is a great advantage in the construction industries

GlobeCore is one of the most successful and reliable manufacturers of bitumen equipment.  Years of experience and extensive marketing has stimulated continuous improvement of existing technologies and the developing of new and better ones making the GlobeCore equipment a worldwide industry leader.

The production process of bitumen emulsion is based on dispersion of bitumen in water.  A mechanical colloidal mill separates the bitumen into smaller particles. Due to the emulsifier’s physic-chemical energy, surface tension is enhanced at the interface between the hydrocarbon and water phases and forms a film around the particles.

The GlobeCore UVB unit is designed for processing both cationic and anionic bitumen emulsions.  The great demand for GlobeCore equipment is the result of the versatility, flexibility, and the number of many other advantages offered by the UVB unit.  This demand has also served to drive the industry to research and develop new and better technology.

The GlobeCore UVB-10FS model is similar to technologies of its kind from perspective of construction.  The letters “FS” in the model designation represents an improved set of components that provide additional security and special features that include the presence of a heat generator, container for the generator, and a removable tank.  The entire unit consists of 5 parts that can easily be placed in 20×40 cubic containers if needed to be transported.

This kind of UVB equipment is intended for use in both outdoor and indoor applications.  Typically, the UVB is a semiautomatic piece of equipment that consists of separate units connected by pipelines that mounted on the same frame.

The main functional blocks for the production of bitumen emulsions are the aqueous phase block, and the emulsifying block.  They are connected to containers holding emulsifier acids and thinners.

The main block of the UVB-10PK is a bitumen boiler.  Bitumen, before being fed into the unit, is prepared in a mini-laboratory equipped with various devices for testing the emulsion, pH levels, and chemical content.

The UVB-10PK unit has a bitumen receiving unit that has a lift for loading and unloading bitumen products. Two people, the operator and the laboratory technician, control the whole setup.

Heating occurs by means of thermal oil that is supplied from the heater through piping in each individual block.  Operational performance of the UVB-10PK is 8 m3/hr.  At this performance level, power consumption is about 96-100 kW.

The package also includes a bitumen storage section.  This section consists of a container in which there is a system for heating water and has a thermo generator.  The top bitumen storage section is equipped with a tank with either one or two receptacles for receiving the emulsion.  Both the Bitumen storage and Emulsion tanks are equipped with stirrers.

The volume of bitumen storage equals 30-32m3, water storage equals 8-10m3, the emulsion tank equals – 16m3 and the bitumen boiler equals – 10m3.

With full integration, multi-directional operation, and versatility, the UVB- 10PK has become a very popular and profitable asset.
