HMA Temperature Differentials – Resources & Educational Materials
HMA Temperature Differentials were the topic of our most recent newsletter and we’ve heard feedback from some of you that you like to see additional resources listed here on our blog. For anyone interested in learning more about temperature differentials, segregation and how to manage the impacts, check out the following:
- Pavement Interactive article on Temperature Differentials (we especially like the “sequence of events” graphic): http://pavementinteractive.org/index.php?title=Temperature_Differentials.
- Pavement Interactive article about Segregation During Transport (including a short video of roads showing the effects of temperature differentials): http://pavementinteractive.org/index.php?title=Segregation_in_Transport.
- Pavia Systems Trucking Course, which highlights many best practices, including how to prevent temperature segregation: http://training.paviasystems.com/catalog/view.php?id=34 (we also talk more about this course in our blog post on Aggregate Segregation from last August).
- Pavia Systems Components of Compaction Course, which covers compaction and cessation temperatures as well as many other best practices for compaction: http://training.paviasystems.com/catalog/view.php?id=3.
- WSDOT Materials Lab “tech notes” about Temperature Differentials: http://www.wsdot.wa.gov/biz/mats/Pavement/Technotes/TemperatureDifferentials.pdf.
