Top Asphalt Sealcoating Tips
Pavements play a crucial function in the transportation process. These pathways provide smooth, durable surfaces for vehicles, other movable crafts, and even pedestrians to traverse.
One such material used to build this infrastructural component is asphalt. Interested parties are urged to read this brief blog offering an overview of asphalt, a safeguard known as asphalt sealcoating, in addition to tips designed to ensure the sealcoating administration process is performed correctly.
Asphalt is a type of concrete composed of several materials including sand, gravel, and crushed rock. Once these items are mixed, they are held together by a chemical product called bitumen.
This vital infrastructure product is created inside asphalt-producing plants. These facilities are especially-constructed to accommodate the production process, which involves working at extremely high temperatures.
The Different Types Of Asphalt
There are several categories of asphalt. Each differentiation is constructed to meet specific conditions and elements. Specific types include:
Warm mix asphalt, also abbreviated as WMA, is typically made at temperatures ranging anywhere from 20 to 40 degrees Celsius less than those employed to construct the hot mix variety.
Proponents of this material suggest that is safer and easier to produce because lower temperatures produce less harsh fumes and more optimal working conditions for the administering construction crews. Additionally, the product cools faster, which expedites how quickly the structure in question may be traversed upon.
The hot mix variation is produced at an astounding 150 to 180 degrees Celsius. This material produces a difficult work environment but is considered extremely durable and most likely to withstand the most challenging environments.
These preparations are made without heating the mixture. Construction and roadway experts opine that this specific variation is best designed for lightly-traveled roads or pathways.
Asphalt’s Practical Purposes
Most people associate asphalt with roadway construction. However, the product has other practical uses. The material is also often employed to build walkways, driveways, airport runways and is even occasionally used as roofing for homes or commercial structures.
Sealcoating is a substance designed to preserve asphalt’s longevity and protect said material from potentially detrimental factors like natural aging, extreme temperatures, weather events, direct sunlight exposure, roadways salts, waste from vehicles like gasoline, oil, and other substances, and the repetitive movement of pedestrians.
Sealcoating is a liquid incorporating several substances such as water, filler, binding agents and other materials created to strengthen the safeguard’s capacity to perform critical functions like repelling excess water and increasing its resistance to salt and other chemicals.
Researchers have found that sealcoating products, on average, increase asphalt’s longevity by roughly 300 percent. Moreover, the sealcoating application process is estimated to be one-third the coast of full asphalt replacement.
However, a sealant’s effectiveness can be maximized by adhering to the following suggestions:
Perform A Careful Inspection
Sealcoating may prove less efficient when covering damaged asphalt construction.
Therefore, prior to beginning this process, project overseers are encouraged to carefully examine structures for problematic issues such as cracks, scratches, stains, or downright crumbling.
Moreover, construction experts stress the most thorough checks should be performed on the corners. These regions are the most susceptible to deterioration and damage.
Execute Needed Repairs
Should any major cracks or holes be detected, said flaws are to be addressed prior to sealcoating. It is important to realize that sealer will protect the structure but not either eliminate pre existing problems or prevent said maladies from worsening over time.
Sealer will not eradicate existing grease or fuel stains. These materials not only make the structure in question appear unsightly but could result in harm as time progresses. Ergo, before commencing sealant application, such stains must be thoroughly removed using scrub brushes and degreasing products.
The structure receiving sealcoating should be completely cleaned before placing said material.
First, all environmental debris such as dirt, dust, leaves, and other types of foliage need to be brushed away. Once this task is complete, the construction in question should be thoroughly doused with water to remove existing dirt and other stubborn products like sand.
