INVESTIGATION ON THE STRENGTH OF THE RECYCLED

Asphalt recycling is not a novel concept. Cold recycling dates back to the early 1900’s. The first hot in-place recycling was reported in the literature in the 1930’s. Modern asphalt recycling technologies that are used today evolved in the 1970s (2,4 ). Asphalt pavement is generally removed either by milling or full-depth removal.
