    摘要: A pavement composition includes a recycled hot mix asphalt (HMA) sheet mix composition including more than 50% and up to 100% recycled fines mixed with a rejuvenating agent. The recycled fines of the HMA sheet mix are separated from a reclaimed asphalt pavement (RAP) composition and substantially all of the recycled fines are capable of passing through a sieve having an opening size of ⅜ inch (9.5 mm). Pavement systems include an existing pavement layer and a thin-lift overlay made of the recycled HMA sheet mix on the existing pavement layer. Pavement systems also include a three-layer system including a leveling course layer, an interlayer, and a surface course layer in which the leveling course layer and/or the surface course layer include a recycled HMA sheet mix composition.
