Asphalt maintenance is not an easy patch job. Repairing potholes and damaged areas is critical for protecting your asphalt investment. If not properly maintained, even the smaller cracks become larger holes that undermine the whole pavement. For one, you need to be educated about additives and sealants for asphalt.
When doing asphalt repair, you can ask your contractor to add sand. Sand has many benefits for asphalt repair such as increased solid content, skid resistance, durability, decreased sun glare, and minimized minor deformities. Despite the proven benefits of sand, not all contractors mix sand because they do not own the proper equipment or unable to mix sand in barrels manually. Either way, it is best to ask your contractor if they can make arrangements to add sand in asphalt repair for improved safety, durability, and appearance.
Benefits of Additives
Aside from sand, asphalt repair is also better with additives. Latex additives provide benefits such as allowing a greater volume of sand to be included in the asphalt mixture, dries quickly, making asphalt oil and gas resistant, darkening the color of the asphalt for better appearance, and improving and sealer's bond with the pavement. Due to fast-drying characteristics, additives significantly shorten the curing times of the pavement. With additives, contractors can reopen the area and continue working in as short as 30 minutes. However, for best results, it is best to ensure the compatibility of certain additives with the specific brand of sealant used for this specific asphalt repair. Different additives lead to different sets of benefits. Some contractors use only one or a combination of two or more additives.
Benefits of Sealants
Contractors also use asphalt sealants when doing asphalt repair. Some contractors have their own branded sealants that they use. Sealants contain fine silica sand that helps improve traction in the pavement. However, sealants need adequate curing time before additional work such as parking lot striping or putting additional coat should be done. Likewise, sealants cannot be applied during extremely cold weather or during nighttime when no sun's heat can warm up the pavement. Sealants can be applied only if air temperatures are within 50°F to 70°F. Additives help address these curing times and temperature issues with sealants.
In the end, the benefits of additives and sealants are enhanced by the use of sand and their compatibility with one another and work conditions. Your contractor should know which additives and sealants can be used for your asphalt maintenance project. Contact a company, like City Wide Services, for more help.
The patio that was behind my house when we bought our house four years ago was in terrible condition. The previous owner seemed to have installed patio stones himself and didn't do a very good job doing so. The stones were all cracked and uneven and made it difficult to enjoy the little time that I did spend out there. I decided that the old patio had to go and that I would have a new patio professionally installed. If you are considering a new paved patio, visit my site. There, you will find several great ideas that can help you create the patio that you love spending time on.
