Recycled asphalt pavement, or RAP, is a common paving material used in several applications all over the world. In lamest terms, RAP is old asphalt that has been removed and reprocessed for reuse. It is milled into gravel and mixed with other high-quality, well-graded aggregates coated by asphalt cement. When compressed, it binds back together to form new pavement. It is an effective and eco-friendly selection for driveway, parking lot, and roadway paving.
If you are familiar with the application process of standard hot mix asphalt, then you will should have no problem comprehending the application procedures for recycled asphalt pavement (RAP). This is because they are very similar to one another, in the beginning. First comes proper grading and excavation, followed by water runoff planning, debris clearing, and then tact coat application. This type of paving material is best lain with an automated paver and vibratory roller. This allows for efficient and uniform paving results and smoother finishes.
Since RAP still contains many of its natural oils, post-application is naturally finished off when the sun heats the surface, allowing the oils to bind the pavement into one, uniform surface area. This produces much less dust and leaves behind a finer finish.
Many people choose RAP over processed gravel and other paving options because it is long-lasting, cost-effective, and eco-friendly. RAP is sturdy and won’t become muddy or soupy in rain or wet weather. Also, it can make a fantastic base if you ever choose to pave over it with another asphalt material.
It is important to trust a paving professional with RAP application, as well as, any other pavement or sealcoat application. They retain the proper tools, training, and insurance to provide safe and consistent results. DIY paving projects are extremely messy, risky, and time-consuming. It is wise to trust the project to a professional in the field.
