The chart below reflects the temperature to hit for each specific roller. Creating density is easiest when you’re at the highest temperature for the type of roller you’re using. This is achieved when the mix is still hot, regardless of the type of mix you use. To reach optimal compaction, you need to hit the optimal temperature for your mix. Here are a few practical tips to help your paving crew achieve both density and production: Smoothness of the road is directly impacted by the compaction efforts. Operators only have a limited amount of time to get the best density from your asphalt mix. Compaction starts behind the screen – both tamping and vibratory. What is Compaction?Ĭompaction in its most basic form is the act of getting the air out of your asphalt mix in order to reach peak performance of your mix. To assist contactors in attaining high quality compaction, Todd Mansell, Product Application Specialist for Caterpillar, offers insights on the best practices for asphalt compaction. It can be difficult to achieve optimal density of your asphalt mix, but by changing one or multiple facets of your daily operations, you’ll be on your way to smoother, denser asphalt. Smooth pavement is the goal, but there are many factors that play a role in the end result of your blacktop.
