Several important factors determine how productive an asphalt paving company is. The rate of operation is affected by the number of rollers in use. A single roller takes about 15 minutes to compact an asphalt surface, so using more rollers would increase productivity. However, the company chose to use only one roller, perhaps for cost reasons. Regardless, the productivity obtained from the MicroCYCLONE model was well within the company’s expectations. In this article, we will look at the main factors that determine the productivity of an asphalt paving company.
Preventive maintenance is essential. While potholes are inevitable, they can be avoided. You can prevent them by limiting traffic and parking on a new pavement before cracks develop. The best way to avoid potholes and other types of damage are to keep the pavement well-maintained by the professionals at SC Driveway Paving Charleston. This will prevent you from replacing the pavement when it is already too damaged. Pothole damage can also be avoided by avoiding parking in the same spot daily. Avoid using sharp objects and leaking fuel. With time, these marks will fade away.
Another factor to consider is the density of asphalt. Typically, asphalt pavements are made up of a binder and aggregate. The binder layer is made of bitumen and is mixed with oil. Asphalt is weighed several times before it is put into place. It must be allowed to dry for 24 hours before it is deemed suitable for driving. This is because asphalt oxidizes, releasing extra oils from the binder. Curing prevents this oxidation, which is what turns asphalt gray and causes cracks.
The temperature of the asphalt mix is critical. A cold climate makes asphalt harder to compact. The temperature should be controlled to a degree that will support the roller behind the paver. When the asphalt mix cools too much, it will become impossible to compact it. This makes compaction difficult and can result in a hard, brittle pavement. In addition, it must remain hot for a minimum of 15 minutes to prevent it from cooling too quickly.
Although some people consider asphalt work to be a DIY project, the truth is that most homeowners do not have the knowledge, equipment, or skills to carry out the job correctly. A contractor can help homeowners choose the right asphalt, perform the necessary prep work, and lay it in a professional manner. These professionals also have specialized training that can save them money. If you have a budget, it is highly recommended to hire a professional asphalt paving company.
In addition to the varying traffic volume, asphalt mix compositions also have their own properties. For high traffic roads, the mix must be stiff, resist deformation, and resist cracking. It should also be flexible, so it can withstand the pressure of vehicles on it. Besides, it should have good workability, which ensures full compaction. These characteristics will determine the durability of the asphalt pavement. When selecting the right asphalt mix for your project, you must make sure that it meets the demands of the project.
The Superpave system has a far-reaching influence. Its performance-based specifications have become a guide for future pavement research. They are widely used around the world. The technical advancements and organized research program made the program a success. The report, written by Rebecca S. McDaniel, details the various factors that influence the strength and performance of an asphalt pavement. The lessons learned from this large research program can be applied to other large scale projects.
Cold In Place Recycling (CIPR) uses grinding machines to transform the pavement into a base material for paving projects. This process uses additives to ensure stability of the asphalt mixture. The crushed aggregate is then applied directly to the hot asphalt oil layer. Unlike self-propelled pavers, this process is not suitable for parking lots. The process may cause some tracking during hot weather. Also, it is not practical to use this process on parking lots because it can create a slippery surface and can lead to excessive dust in the area.
The National Asphalt Pavement Association (NAPA) is a professional association that represents the interests of asphalt producers and contractors. It promotes quality asphalt pavements by supporting active research on paving methods and improving product quality. The NAPA also provides educational opportunities for its members. The NAPA membership numbers over 1,100 companies. The organization was founded in 1955. Its members include asphalt producers, contractors, and suppliers.
