Pavement Distress Spotlight:
This week, we’re highlighting a common type of pavement distress—what it looks like, why it happens, and how it’s best addressed. Using industry research and decades of hands-on experience, we’ll help you understand whether it’s a maintenance fix, a repair need, or a sign of something bigger.
Asphalt Raveling
Raveling can be caused by problems related to the mix design, construction, or environmental effects, including:
-Asphalt being mixed with dirty aggregate, to which the binder in the mix
-Insufficient binder in the asphalt mix.
-Segregation of the aggregate in the mix prior to being laid.
-Inadequate compaction of the asphalt layer
-Breakdown of th binder over time or due to exposure to solvents and erosion of fine aggregate.
To prevent raveling, you can follow design and construction best practices. You should Prevent exposure to solvents that would break down the binder.
Tips on responding to raveling: Before putting a treatment over raveled asphalt, clean all loose pieces of asphalt and aggregate from the old asphalt.
