Top What is a good candidate pavement for rehabilitation with hot in-place recycling?
 Any hot mix asphalt pavement with surface distress and a stable base.
 
Top How hot does the hot in-place recycling process heat the pavement?
 The pavement surface shall not exceed 350o F. The recycled mix should average at least 225o F.
 
Top What is the expected production rate of hot in-place recycling?
 Depending on the weather and road conditions, 1 to 2 lane miles per day.
 
Top How deep do you process with hot in-place recycling?
 1 to 2 inches are the most common treatment depths specified.
 
Top When can traffic be allowed back on the pavement?
 Same as with hot mix asphalt overlays, or sooner, an hour or so at the outside.
 
Top Does the hot in-place recycled surface have to be overlaid?
 Some methods do require an overlay be placed, some methods contain an overlay with the recycling process and some methods do not require an overlay.
 
Top Can hot in-place recycling be performed at night?
 Yes, at a significant increase in operational costs and decrease in production rates.
 
Top How long has the hot in-place recycling process been used?
 Hot in-place recycling is the oldest method of asphalt recycling. Some methods of HIR can be clearly traced back to the 1930''s. It is generally accepted that the first boom of HIR equipment and processes occurred in the 1950''s and 1960''s.
 
Top How much does hot in-place recycling cost?
 Hot in-place recycling costs vary based on the differing methods and treatment depths. Typical savings of 20%-50% are achieved with HIR.
 
Top What problems can be cured by hot in-place recycling?
 Hot in-place recycling treats surface distress problems in the top inch or two of the existing pavements. HIR also re-establishes the ride quality of the roadway. HIR will not improve any base or sub-base problems.
 
Top What are the weather limitations for hot in-place recycling?
 Typical requirements are 50o F and rising with no standing water on the pavement.
 
Top Are there any width restrictions in the hot in-place recycling machinery?
 Hot in-place recycling machinery is flexible between 9 to 15 feet.
 
Top How long will hot in-place recycled roadways last?
 Typically as long as the original roadway lasted, or in some cases even longer due to the fact that new hot mix asphalt can be added this improves the structural integrity of the roadway.
