TLN - Identifying Asphalt Roadway Fatigue And Treatments Pavement Management And Preservation
- Apr 27, 2017 (9:30 - 12:30 pm Central Time) – Video Conference
This presentation helps solve the mystery of analyzing roadway deficiencies and selecting a treatment method that works. It will begin with a discussion of the failure mechanisms of pavement that result in pavement thermal and fatigue crack and fatigue along with other load related pavement failures and distresses. Then treatments for addressing the failure mechanisms will be presented with respect to patching and crack sealing.
Machine Patching -- How to do; Proper equipment; Mixes; Why; Estimating quantities; What’s important
Hand Patching -- How to do; Equipment; Mixes; Why; Estimating quantities; What’s important
Cracks Maintenance and Repair
Rout and sealing -- What cracks to seal; How to; Why; Materials; Equipment; Strengths/weaknesses; Estimating amount of sealant needed
Clean and seal -- What cracks to seal; How to; Why; Materials; Equipment; Strengths/weaknesses; Estimating amount of sealant needed
Discuss different sealants -- Low modulus; Extra low modulus; Crumb rubber; Emulsion; MC; Fiber modified sealant; Advantages of each; Weakness of each; Recommendation for use
Dealing with big cracks or cupped cracks – Mastics; Sand mixes; Patching; Slurry/micro leveling
How to minimize cracking of pavements
is a Pavement Specialist with WSB & Associates, Inc. at their Minneapolis office. He has worked for the Minnesota DOT on pavement preventative maintenance methods with the Office of Materials and for Koch Materials Company and the SemMaterials Group as a technical representative specializing in surface treatments for hot-mix asphalt pavements.
Andrea Blanchette, PE,
is a graduate of the University of Minnesota, Institute of Technology, and completed graduate school for civil engineering with an emphasis on pavements and materials. Her master’s research described the effect of heavy agricultural equipment on the flexible and rigid pavements in rural roads in Minnesota, Wisconsin, and Iowa. Andrea joined WSB in 2011 and is developing excellent experience in general civil engineering, GIS, construction administration, and pavement/asset management. Her education, research, and experience working with pavement and materials is a valued addition to WSB’s Construction Services Group, helping to expand an already recognized pavements and materials group.
