Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.
B-1 A P P E N D I X B Revised Survey
B-2 1. Does your organization have any standard practices or specifications for pavement marking removal? Yes No If yes, please provide a copy or a website address: 2. What types of pavement marking removal methods are used or have been used by your organization? Please list the status of the removal type (currently used, no longer used, experimental, never used) types of pavements or road surfaces where each type is used (HMA, PCC, surface treatment, etc.) and the types of marking removed (paint, thermoplastic, tape, epoxy, polyurea, MMA, etc.). Also, please list comments on your satisfaction with the removal types such as the pros and cons. Type of Removal Status of Removal Type Types of Pavements or Road Surfaces Types of Marking Material(s) Removed Comments on Satisfaction with Results (Pros and Cons of the Removal Method) Water Blasting Grinding Sand Blasting Shot Blasting Combination of Blasting and Grinding Masking (black markings, slurry or black tape to cover existing markings) Other (describe):
B-3 3. Describe your organizationâs preferred removal technique and indicate whether this varies by marking or road surface type? 4. Is there a method you would prefer to use or like to try but do not due to environmental impact, cost, unavailability or some other factor? Please explain. 5. Are you aware of any emerging technologies in the field of pavement marking removal such as chemical systems or a combination of mechanical processes? Yes No If yes, please describe and/or provide a website link or more information. 6. Discuss how much pavement damage (surface scarring) is acceptable to completely remove a marking. Are there acceptable threshold levels? 7. Are traces of marking on the road surface acceptable if the majority of the marking is gone? Are there acceptable threshold levels? 8. Does your organization have any measurers of effectiveness to determine the quality of marking removal? (such as amount of scarring of the pavement, amount of marking material remaining, damage to joints or sealer) Yes No If yes, please describe. 9. What are typical removal costs, listed by removal technique/road surface type/marking material? Type of Removal Types of Pavement or Road Surface Types of Marking Material(s) Removed Estimated Removal Cost ($/Line-mile) 10. What are typical production quantities for marking removal (time to remove a specific amount of marking)? List by removal technique/road surface type/marking material. Type of Removal Types of Pavement or Road Surface Types of Marking Material(s) Removed Estimated Production Rate (Line-miles/day)
B-4 11. Describe any environmental concerns or issues associated with pavement marking removal processes used by your organization. Indicate whether these issues are related to solid and hazardous waste, water quality, air quality, or other factors. Type of Removal Types of Pavements or Road Surfaces Types of Marking Material(s) Removed Describe Environmental Concerns or Issues by Marking Removal Process Describe Techniques or Processes Used to Reduce Potential Environmental Impacts for Each Process 12. Describe any worker/general public safety concerns or issues associated with pavement marking removal processes used by your organization. Indicate whether these issues are related to hazardous substances, noise, heavy equipment, traffic hazards, or another safety concern. Type of Removal Types of Pavements or Road Surfaces Types of Marking Material(s) Removed Describe Worker Safety Concerns or Issues by Marking Removal Process Describe Techniques or Processes Used to Reduce Potential Worker Safety Concerns or Issues for Each Process 13. Have you received any public comments about the removal of markings? Yes No If yes, please describe the types of comments (indicate whether the comments were positive, negative, or mixed). 14. Please describe past pavement marking removal experiences (either good or bad) that may be of benefit to this research. 15. Do you know of any other research projects that have evaluated pavement marking removal issues? Yes No If yes, please describe and/or provide a website link.
