• Location RAS is incorporated into HMA drum
• Temperature
• Moisture content of RAS and other aggregates
• Retention time in HMA drum
![Page 66: January 14 – 16, 2007 ● San Antonio, Texas Shingles Recycling: CMRA’s Best Practices Guide A presentation at the CMRA Annual Meeting On Sunday, January.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e035503460f94aedae8/html5/thumbnails/66.jpg)
Potential Benefits
• Rutting resistance (especially at warmer temperatures)
• Conservation of landfill space
• Economic savings to HMA producer due to reduced need for virgin asphalt binder (add oil)
![Page 67: January 14 – 16, 2007 ● San Antonio, Texas Shingles Recycling: CMRA’s Best Practices Guide A presentation at the CMRA Annual Meeting On Sunday, January.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e035503460f94aedae8/html5/thumbnails/67.jpg)
Potential Disadvantages
• Contamination (tear-offs)
• Added costs of processing and use in HMA
• Increased low-temperature / fatigue cracking
![Page 68: January 14 – 16, 2007 ● San Antonio, Texas Shingles Recycling: CMRA’s Best Practices Guide A presentation at the CMRA Annual Meeting On Sunday, January.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e035503460f94aedae8/html5/thumbnails/68.jpg)
Mitigating Low Temperature Impacts of RAS
• Use less RAS instead of 5%(e.g., use 2% to 3%)
• Adjust the virgin binder PG to one grade softer (e.g., PG 52-34)
• Assure minimum amount of virgin binder (regardless of PG)
![Page 69: January 14 – 16, 2007 ● San Antonio, Texas Shingles Recycling: CMRA’s Best Practices Guide A presentation at the CMRA Annual Meeting On Sunday, January.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e035503460f94aedae8/html5/thumbnails/69.jpg)

Dust Control
• Comprehensive plan• Spray with optimum amounts of water at
critical grinding stages• Shrouds• Negative air (i.e., suction) systems to
remove ambient dust and light debris• Standard employee health and safety
protection equipment and procedures

Removal of Nails and Other Ferrous
• Assure an even layer of material on conveyor belts equipped with magnets
• Multiple magnets (minimum of three or four)• Use combination of pulley belt and overhead
magnets• Combine metal detection device with manual
hand sorting for final quality control process

Final Product Quality
• Conduct adequate testing
• Provide quality guarantees
• Keep covered to reduce unwanted moisture

Final Product Preparation
• If stockpiled, pulverization of final product may be necessary immediately prior to use in HMA plant
• Alternatively, use RAS “fresh” about one week after production to avoid extended stockpiling

Asbestos Testing
• Explore exemption alternative, but if not, then …..
• ….develop product sampling plan• ….develop supply sampling plan on
whole shingles / mixed roofing scrap• Recognize that more initial testing may
be needed to gather adequate baseline data

Additional Environmental Risks
• Air emissions impacts from tear-off RAS in HMA plants
