Asphalt paving is a technique that allows paving the road by placing the asphalt and then compacting it using a heavy roller, which is driven over the asphalt. HMA (Hot Mix Asphalt) is generally used to pave the roads due to its smoothness and safety advantages. Owing to its advance benefits like the construction of a safe, quiet and durable road by saving a large amount of money on construction and maintenance.
Given below are some usefultips that will help you in improving its quality as well as sustaining the pavement for a long time-
- Keep away from water drainage
It is crucial to avoid water intrusion under or near thearea as it will otherwise cause unwanted repair charges besides reducing the life of the pavement. This should be your primary consideration as if ignored; the consequences will only put your investment at stake.
- Plan and prepare the asphalt paving area
Before actually performing the asphalt paving, it is necessary to plan and then, properly prepare the machine and screed setup. Check that all the specifications are correct, to ensure that the paver is in good working condition.
- Make sure you choose quality materials
Hot Mix Asphalt (HMA) is a combination of 95% stone, sand, or gravel mixed together with asphalt cement which is a by-product of crude oil. Depending upon the gradation and the amount of asphalt binder, the durability of the mixture is measured.
- Regular Sealcoating to Fill Cracks
Sealcoating is a preventive method to protect the asphalt from exposure to water as it tends to lose its vital structure when it comes in contact with water. It is thus, necessary to seal the pavement in every 3-4 years to maintain its strength.
- Allow optimal compaction
Compaction is a factor that must be achieved to increase the number of roller passes by imparting high density or speed. It is essential so that the pavement can handle heavy traffic and all types of loads.
- Measure the pavement thickness
The thickness of the pavement holds a great value as it needs to maintain the integrity of the final structure. Thus, you must set the right angle of attack so that the pavement is constructed with a fine thickness.
- Set the right paving speed and temperature
A constant paving speed is a pre-requisite if you desire to have a uniform pavement thickness. A temperature range of about 225ºF to 275ºF (107ºC to 135ºC) is optimal to achieve the best results from the pavement.
- Adequate Maintenance
Debris-free asphalt is quite necessary as it will keep the pavement tidy and keep a close look at the wear-and-tear of the pavement. Pay attention to cracks and immediately get them filled to avoid further damage.
All in all, keeping in mind these simple tips will not only help you design an asphalt pavement that is beautiful-looking and long-lasting but also guide you on how to keep it well-maintained for a lifetime.
