By incorporating recycled content, the City saves on new material and the costs associated with transport and landfill fees. Respirable dust containing crystalline silica may be generated when hardened asphalt concrete is subjected to mechanical forces, such as in demolition work, surface treatment (sanding, grooving, chiseling, etc. With RAP, yesterday’s pavement becomes today’s streets . Jun 9, 2025 · Researchers examined the long-term safety and durability of reclaimed asphalt pavement compared to new pavement materials. This expanded version of the Texas Asphalt Pavement Design and Construction Guide provides up-to-date information on asphalt pavement materials, engineering, construction, and maintenance. Break up the RAP, not crush the aggregate (avoid white rock) and dust generation. Recycled Asphalt NYC DOT is a national leader in the use of recycled asphalt pavement (RAP). Screen RAP prior to “crushing”. HOW DOES RAP WORK IN OTHER PARTS OF THE WORLD? Recycling asphalt pavement is a common practice. While RAP offers a low-emissions and low-waste alternative to conventional asphalt, it is poorly utilized across Canada. More than 90% of paved roads in the U. S. At elevated temperatures, RAP can cause thermal burns and release Hydrogen Sulfide (H2S). Direct contact with the eyes can cause mechanical damage. Only crush the RAP that needs to be crushed! Avoid breakdown and dust generation. The general perception is that recycled asphalt is of poorer quality or isn’t as durable as asphalt made of virgin material.
