6 Important Stages To Pave The Asphalt Road
Asphalt paving includes various steps such as clearing the road, constructing the base, paving asphalt aggregate and smoothing the road. Most people prefer to use asphalt material as it provides a smooth and durable road surface.
Asphalt material is capable to handle heavy load and the huge volume of traffic, therefore, it is the perfect material for highways. It is a perfect material for the construction of parking lots, driveways, airways, and commercial pavements as well.
This type of pavement has good strength that makes it suitable for all kinds of pavements. Most governmental organizations prefer asphalt for road pavement due to its durable nature and low maintenance required. If asphalt is properly laid by experienced contractors, then you do not need to replace it for at least 20 to 25 years.
The asphalt paving material is comprised of stone, liquid asphalt and sand as well. The liquid substance is a type of black sticky material that can bind the entire material together. The asphalt is viscous and therefore it is also available in semi-solid form. The biggest advantage of asphalt is that it is made of recyclable material.
Another biggest advantage of asphalt pavement is that it can be constructed easily. Asphalt paved roads do not require “cure’ time. That means, they can be used by commuters immediately after the completion of the road profiling and pavement process.
But, it is better to leave it for one day. The asphalt surface forms a non-skid road for travelers and it requires the least maintenance. You have to prevent its surface from the effects of oxidation and adverse weather conditions.
If you are looking for important steps that are used to pave asphalt road then read the following points:
Step 1: Removing Old Surface
First of all, you have to remove the existing surface. Mostly, old asphalt material is recycled and can be used again and again. Approximately 70% of asphalt material can be used again and again.
That means asphalt is eco-friendly and leaves less hazardous impacts on our environment. For removing the existing asphalt road, you have to use heavy machinery like bobcats, ladders, dump trucks, etc.
STEP 2: Grading And Forming Slope
The proper drainage system plays an essential role in paving the asphalt surface. By implementing the grading and sloping process, the drainage system of the road can be efficiently maintained.
As we all know that water is the main reason for road damage and potholes, therefore, the drainage system plays a vital role in the long life of pavements. The grading and slope forming process can help you to maintain an optimum drainage system.
STEP 3: Preparing The Paving Material
We all know that asphalt is a mixture of gravel, stone, sand and liquid asphalt. Therefore, before paving the road, it is important to collect the required material and mix them to form the paving mixture.
The mixture is supplied with 300 degrees Fahrenheit temperature. When the required material obtained then it is used to spread over the surface when it is hot.
Always hire experienced workers for asphalt road pavement, as it needs skills and good experience. As asphalt is very hot and it can lead to major hazards, therefore you should take the help of experienced contractors.
When the mixture is spread over the surface, then it will immediately start cooling down so that you can drive over this road immediately after finishing the pavement process.
STEP 4: Lay Down The Paving Material
The obtained mixture is loaded in the receiving hopper and then the haul truck is placed right next to the paver. To avoid any misalignment, the rear wheels of the truck must be in contact with the roller.
The paver will exert force on the truck and push it in forwarding direction while paving the surface. If any distortion takes place, then the entire process will be delayed for some time. It is so because the workers have to reposition the truck.
STEP 5: Check The Asphalt Uniformity
Immediately after spreading the first load of asphalt, you should check the asphalt texture. No segregation should be there. The layer of asphalt should be spread properly Also, the operators should not let the clings form on the sides of the hopper.
STEP 6: Compaction Stage
This is a very important process in the surface paving technique. This technique ensures that the paved surface shows integrity and capable to handle the heavy load and high volume traffic.
There are different types of rollers available in the market such as steel-tired static, vibratory and steel-tired static rollers. You have to pick the right one according to your road construction process.
Experienced contractors can pick the right compactors. Therefore, you should hire a renowned road paving contractor. They can help you to bring the optimum road paving results.
