There are different types of HMA mixes available, with some measures that have to be taken and done meticulously to arrive at the right selection. The contractor will contact the asphalt mix supplier to create a mixture appropriate for positioning the asphalt thickness. Take note that stony mixes are not the best options for certain applications. The same goes true for mixes that contain specialty materials.
Traditional compact blends are the ones ideal for parking lots and driveways. The use of more sand offers a better water shedding pad. It also makes the mix lightweight. However, if you intend to mix the asphalt, ensure that the contractor buys the mix from reputable local suppliers.
Contractors would definitely have their favorite recipes that worked well for them before. If you are not familiar with asphalt pavements, it is best that you ask them to give you a sample of how the finished work will look like so that you get the matte and mixture that suits your requirements.
Compacting and Paving Techniques
Ensure that the subgrade of the asphalt pavement is stable before starting the paving process. It’s important for the soil and backfilled areas to be well compacted. Any settlement should have occurred at this point. Drive a dump truck or a loaded vehicle over it to make sure that the work platform is secure and stable. Upon the completion of the subgrade, the next step is to assemble, form, and compact the aggregate base.
Paving must only be undertaken only if the weather condition is good. Don’t do any work if it’s cold or snowy outside. Proper compaction is important to the future performance of the pavement, and you won’t do a good job during wet and cool weather. You have to use the right compacting equipment as well.
Ensure that the contractors are working closely with their chosen suppliers to monitor the HMA temperature. It must never be overheated or damage can be expected. The mixture temperature must be maintained throughout the compaction process.
To order to prevent segregation, the contractor must also monitor the handling and location of the materials used during the entire project. Doing so should improve workmanship. Use a paving machine for the job.
Your asphalt driveway investment must be safeguarded. Driveways and parking lots have to be maintained well to prevent drainage problems, to provide edge protection, and to repair the paved surface.
Water spells trouble for asphalt pavements. Every low position known as the water pool must be corrected with a patching mixture. Ditches, drain inlets, and gutters should be open and clear.
The bottom of the asphalt pavement must be protected with aggregates or soil wedges. Curb blocks may also be utilized to discourage vehicles from driving very close to the edges of the pavement.
If possible, seal the asphalt pavement. A seal makes the surface water-resistant. Sealing provides not just waterproof coating but also a uniform look.
