In The perfect asphalt pavement that you see is not a result of a single day. It is the consequences of entire efforts, careful planning and appropriate scheduling of each paving step. Whether it is the selection of paving material or getting the required optimum temperature of the paver or compacting the materials at the right time, each step impacts the next.
A little mishap can cause asphalt pavement distress which can continuously irritate in form of different asphalt pavement issues. However, a professional paving company takes care of all these issues. With proper planning and appropriate preparation, we can lend you with a pavement with professional finish and durability.
Here we are sharing necessary asphalt paving tips that need to be consider while paving. Avoid future pavement problems with these asphalt paving tips!
Asphalt Paving Tips That Help to Improve the Quality of Asphalt Pavement
A right asphalt pavement service is quite necessary for long life and durability of the road. A lot of factors are there which can directly influence the quality of the paving mat.
Before you go for paving services, you need to know the whole process of paving and what affects it most. Because, even a little mishap in the paving process can ruin the whole asphalt pavement.
Just follow these quick paving tips while asphalt laying procedure for a durable and robust road.
#1: Checking Paver Setup for Smooth Pavements
Before the work starts, you need to check all the paving equipment and components. Before startup, check the level of fluids and gauge.
The component directly in contact with asphalt throughout workday can stick to it. A coating solution or releasing agent needs to be applied to such components.
Screed setup and proper machine planning can save both time and efforts. You can set up the project specifications like width, crown and mat thickness. The screed can be preheated in order to stop mat sticking and dragging. The standard temperature range is 225ºF to 275ºF (107ºC to 135ºC).
The setup of screed plate determines the thickness of mat and paving dept. an experienced project engineer can yield the best mat depth after analyzing the pavement usages and traffic volume. After making sure the working condition of paver, proceed further on the other factors responsible for pavement quality.
#2: Laying a Quality Mat
After ensuring the paver set up and other initial checks, you need to consider other important facts. Getting a quality asphalt pavement mat depends on a number of facts.
Before laying the mat consider the quality of paving material, level of the mixture applied and the paver speed for compaction. All of these play a compelling role in maintaining the pavement quality.
Besides these, there are two other factors that significantly determine pavement consistency. The constant consistency of material to the screed and the maintained paving speed, if both of these are ensured, can lay a quality mat for your pavement.
#3: Maintaining an Adequate Head of Material
In a study, it was found that, 95% of the material faults which emerges in pavement is due to improper consistency of material. The improper supply of head of materials in front of screed can cause serious initial paving issues.
Head of material can be described as the mass of paving mix which is supplied to the screed for paving. If there is a fluctuation in the supply material, this can cause uneven surface. That makes it impossible to get a pavement with even and smooth finishing and you would encounter a wavy surface.
The amount of material should be constant across the whole required region to be paved. This only ensures of an even and professional pavements. The screed operator is responsible for monitoring the level of materials. However, the screed paver are now equipped with sensors that manages the consistency of material; in order to provide you with a continuous and smooth superficial roads.
#4: Paving Speed Matters
Lots of asphalt distress occurs only due to improper paving speed. This can cause waves, ripples and irregular depth of mat and many other problems. Ideally, the paver operates nonstop whole day, as change in paving speed can affects the uniformity of mat.
When you are setting the paving consider a few things:
- Volume of mixing plant and output.
- Rolling rate
- Compaction rate
- Distance of the mixing plant to the paver
- Capabilities of crew
Nowadays, some paver are equipped with speed limiters, all you need is to set the limit. After the proper set-up of the paver, with correct paving material and constant paving speed, now you need to consider the compaction operation.
#5.: Compaction Need To Be Checked Out
The pavement needs to be prepared to cope up with heavy traffic, unexpected load and harsh winter (according to location). This can be only possible if the asphalt paving preserves its integrity and strength. For that the asphalt base and different asphalt layers needs to be compacted firmly.
If the paving is not done properly with the required compaction or density, it can create problem. In such a situation the asphalt road won’t be able to execute the adequate support required for heavy traffic and this would lead to breakage of materials
Although, if the compaction is done properly, you don’t need to worry about the cohesion of the roads. For best compaction result below-mentioned three facts play important role:
- Temperature of Mat
- Mat depth or thickness
- Compactor rolling patterns.
Further we have discussed the facts in details. Just Scroll Down To Read…
#6: Mat Temperature and Thickness
The first fact that has key role in compaction is the mat temp. The process starts while the mix has sufficient fluidity. This allows the aggregate particles move better in order to exclude voids or air in paves.
In few cases, we have encountered the compaction time was lesser than 10 minutes. An experienced compactor operator can conclude the time in cooling down of hot mix asphalt in accordance with the weather conditions.
Thickness is also an essential factor to get a better compaction. As mentioned earlier, the project engineer decides the thickness of the compaction. He takes in account the estimated usage and traffic of the pavement to choose the mix design and mat thickness.
After the different asphalt layers are appropriately placed and compacted, the next asphalt-paving step is the rolling pattern.
#7: Rolling Pattern
Rolling pattern is the final step which plays critical role in yielding professional pavement. It’s responsible for the durability and smoothness of the roads. For better rolling results, it need to be down before the temperature of laid material drops down.
The application of compactor needs to be done carefully. Certain diversion can lead to bumps and depression.
Don’t stop the compactor at the same place, instead stagger stop. To avoid imperfection change the direction also. You can also limit the length of roller area; this would help it keep the compactor with paver.
#8: Intelligent Compaction
Intelligent Compaction (IC) has led the compaction to a next level. It provides better maintenance of record, elevated uniformity in compaction, enhanced productivity and automation. Although, previously used Intelligent Compaction (IC) lacked a lot of features.
Now with the enhanced technology and continuous research, the system is improving. Now we have tech that evolves real-time detail about the pavement. Whether it is color-coded reading of density, numerical density reading, the passes’ number and temperature, you will get all at fingertips with android-based interface. Doesn’t this sound exciting?
