Asphalt tanker trailers, also called bitumen tankers, are special semi-trailers, which is composed of trailer chassis, pump, tank body, burner, and heating system. Rockwool is used for insulation inside and a stainless steel surface covers the outside of the asphalt tanker body. This makes asphalt tanker trailers durable and quality high.
Let us look at these asphalt tanker trailers in more detail.
Part1. What is an Asphalt Tanker Trailer?
Asphalt tanker trailers are used for moving liquid asphalt from one place to another. These trailers use diesel or gas burners to heat or insulate the liquid during transportation. Additionally, asphalt tankers are used for paving road and and treatment of asphalt surfaces.
These tankers also play a role to superficially pave and add another treatment layer on the surface in the plant-mixed black gravel road. Some trailers are designed to unload themselves using the inclination angle designed for the purpose. The angle is about 17 degrees, which helps the trailers to unload automatically at certain destinations. Moreover, the heaters blow air continuously to heat and insulate the asphalt in place automatically. These semi-trailers are ideal for the transportation of asphalt.
When we look at an oil asphalt tank, the heat transfer uses organic heat-carrying agent. The heating agent uses coal-fired, oil-fired or a coal-fired source to maintain the required temperature inside the trailer. The asphalt tanker trailer is low-pressure, safe, high-temperature and sanitary thereby keeping the material safe and untethered during its transportation.
The temperature can be controlled while transferring the asphalt from a larger trailer to a smaller tank without overheating the entire tank. Large-scale industries and factories use asphalt tanker trailers to transport huge amounts easily and quickly. Bitumen tanker trailers are with 2 to 4 axles and the tank body is designed differently. The design of bitumen tank body is according to different steel needs and desired thickness.
Part2. What is the Principle of Asphalt Tanker?
The asphalt tank is principally used for heating the asphalt to keep it usable upon arrival at the destination. The tank circulates the heat using a hot oil pump to maintain different sets of asphalt temperatures. The temperature must be held in the tanker to keep the properties and performance of the asphalt intact.t.
The heating time is another essential thing to check. If it is heated for too long and at higher temperatures, the quality of the asphalt reduces considerably. This influences the asphalt’s performance and properties, directly affecting the project’s quality. Over 180°C, the asphalt starts to decompose.
The asphalt break down to free carbon that affects the purpose of the asphalt for any given project. Asphalt is cohesive and ductile, but carbides’ precipitation spoils it considerably once the proportion of free carbon increases. The performance and properties of asphalt are thereby reduced.
Part3. How to Operate an Asphalt Tanker?
Operating an asphalt tanker is not an easy task. The drivers are well trained and experienced before taking on long journeys of transporting liquid asphalt. Safe handling by end workers and tanker-truck drivers is of high importance. The high temperature of the asphalt and driving hazards in different climate conditions pose a challenge.
The asphalt tank must go through proper inspection before loading. The tank should be clean of debris and other contaminants. In case there is moisture in the tank, the asphalt mixed into it will cause foaming. This foam, when formed, may cause harmful fumes to leave the tank and the operator will be affected.
Part4. How to Load and Unload Asphalt?
Loading
The following are several things that all operators need to keep in mind when loading asphalt into the tank of the trailer.
- Ensuring that the chain covers are in the right places on the rotating drives so there is no chance of entanglement.
- The combustion sources are well-lit and nowhere near open manholes or overflow vents. This ensures there are no fire hazards.
- The distributor motor is on before the value is opened.
- Before opening the storage tank, the loading hose must be attached properly and the bleeder valve should be closed.
- Ensuring that no one is standing close to the valves which may open. This is an added safety measure.
- Once everything is in place, open the valve on the storage tank and pump the desired amount of asphalt at a slow rate. This rate should be appropriate, neither too high nor too low.
- Once the asphalt is finished filling in the tank, the storage valve is closed and the bleeder valve is opened. The pump must continue to work so that all residue of asphalt is out of the hose.
- The tank must have enough space for the expansion of the asphalt when it is heated.
- Once the hose is clear of all asphalt residue; the hose is disconnected and placed back properly in its storage location. The bleeder valve is closed and locked.
- The asphalt levels present on the tank and gauges are also needed to be checked to ensure that sufficient quantity is loaded in the tank.
Unloading
While unloading asphalt from its tank, the operator must ensure that, the chain covers are in their rightful places to avoid possible entangling. The sources of lit combustion must be clear of overflowing asphalt to prevent any fire hazards. Other things to keep in mind during unloading are:
- Checking whether the storage tank is with sufficient capacity.
- The unloading pipe is attached to the truck, and the bleeder valve is closed. Once this is in place, the operator will unlock the storage tank.
- The valve of the storage tank pump is opened and the desired amount is filled at the right rate.
- Once the unloading is completed, the distributor adjustments are made following the operations manual, and the valve is closed.
- Every operator must follow the unloading instructions according to the model of the sucking pipe. The pipe must be cleared out of any residue asphalt by the bleeder valve.
- Once all the steps are finished properly, the pipe should be disconnected from the distributor and placed back in its storage place. The valve on the tank must be locked and the bleeder valve closed.
Part5. How to Heat the Asphalt Tanker?
A tanker carrying asphalt is usually insulated with a heating device as it is used for carrying bitumen. There are several types of insulated tank trailers used for transporting different materials.
There is water present in the asphalt tanker trailers, and if that contains a colored binder, the temperature at the top should be 100 degrees. Once the dehydration cycle starts, it is important to maintain this temperature. Once the tank level thermometer falls below that position, the suction valve is closed so the water does not flow back due to heating.
The exhaust present on the heating tank is opened by valve that allows the asphalt to enter the heater smoothly. Before the ignition, the tank is filled with water. Once the water is filled, the valve is opened, and once the desired height is reached, the valve is closed.
In the process of heating, the operators should follow the instructions of the pump and that of thermometer and make it on time safely. The asphalt should be pumped at high temperature during the dehydration time. In case the temperature is too high, the internal circulation cooling should be started immediately in order to maintain the right temperature. Asphalt heating tanks should be operated with the relevant principles.
Part6. How to Keep the Asphalt Tanker Insulated and What is the Insulation Material?
The insulation material used in asphalt tankers is rock-mineral cotton and polyurethane. The pipeline is placed at the bottom of the tank for heating. This design make the heat loss rate different in all parts of the trailer. To keep the asphalt taker insulated, there are several things the operator to follow.
The use of an insulated tanker in transport is essential. Industries rely on special vehicle to transport sulfur, asphalt, bitumen, and liquid phenol. The trailer has a long heat preservation duration. The drivers and operators need to install heating tubes in the tanks. There are three types of heating modes, which are used in most insulated trailers.
The heating modes are coal, steam, and diesel burners. Asphalt in liquid state is transported at higher temperatures of about 250. Although such temperatures are supported through specialized means, all tanks are insulated to ensure the heat does not escape. With high temperatures, the complexities of expansion of asphalt happens during transportation. The tank heating system takes care of this difference to maintain the quality of the asphalt.
Part7. What to do if the Asphalt Solidifies in the Tanker?
Commonly, asphalt is used to bind gravel; the main ingredient is bitumen, which is made from processing petroleum. It can also be found in the natural environment. Asphalt is used in many places like road constructions and paving sidewalks.
Sometimes, the asphalt solidifies in the tanker. The adhesive properties of bitumen makes it tough work to get rid of it. But it is possible to dissolve the excess. Turpentine works on solid asphalt is like water works on the sand. The best way to clean a tank is to pour turpentine over the solidified areas and allow it to soak.
If the asphalt has solidified for a few days, it should soak for two to three days. If this happened recently, not much time would be needed to get it off. Using protective gloves while handling the cleaning is essential to prevent health hazards.
Part8. How to Clean Asphalt Tank Trailer?
The process of cleaning an asphalt tank trailer is a lengthy one. First flush the tank with hot water at high speed to remove all residue from the tanker.By this no matter what hard and solidified asphalt will dislocates from its location. After that, detergent is flushed into the tanker to clean all contamination and ensure that all residue is freed from the tanker. Finally, the tanker is flushed with hot water again to remove detergent from the tanker. All detritus is removed from the tanker trailer this way.
Part9. How to Extinguish an Asphalt Tanker Fire
It is not easy to put out the fire of an asphalt tanker trailer. In order to prevent accidents, operators and drivers should take sufficient precautions. In case of fire, the operators and drivers must have fire extinguishers handy. These are usually available in the trailers to ensure that the fire does not spread.
The first thing is to make the vehicle empty and use the extinguishers properly. If the tanker is fulfilled with asphalt, the fire will not go out with just fire extinguishers. The driver must clean up the surrounding areas and call for help immediately. Professional firefighters can do the job if called at the earliest.
Part10. How Much does the Asphalt Tanker Cost?
The current price of an Asphalt tanker is around USD 25,000 to $39,000. Manufacturers make quotes according to different sizes and specifications.
Part11. About Bitumen Tanker Trailer
The different heating system of bitumen tank trailers makes it a unique choice for certain liquid transportation. The heating system includes 1 or 2 burners, pumps, generators and diesel engines, depending on the size of the tank body. This unique feature allows asphalt to be heated and ready for use as arriving at the destination. There are different standards around the world, but the maximum load capacity of asphalt tanker is 60,000 liters. Some countries allow as high as 22,000 liters but that also varies for road and sea transportation.
