RAP/Shingle Processing Plants With Astec's processing plants producers can economically handle reclaimed asphalt pavement (RAP). RAP is produced when old road surfaces are milled up to make room for new pavement.
	Fiber Shredders Astec's fiber shredder is designed specifically for hot mix asphalt producers. In the past producers had to adapt shredders made for other applications. Now this heavy-duty, self-feeding machine is available.
