Pavia Systems: The Gravel Pit Blog

There are several considerations and best practices when transporting asphalt pavement mixes that we discussed about in our most recent RoadReady newsletter, but we also wanted to provide some additional resources on our blog.

Here’s an animation from our End Dump Truck Exchange course that highlights how to properly back into the paver:

There are two articles on Pavement Interactive on transporting asphalt mix that we think provide great supplemental information:

• Ashphalt Mix Transporting (we really like the close up video of the truck loading):
  http://pavementinteractive.org/index.php?title=HMA_Transport
• Material Trasfer Vehicles, which provides a great overview of the types of MTV’s and when/why they are used:

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.
