It’s still plenty hot out there in North American paving zones and that ambient temperature affects your mat and your rolling zone. With WMA designs in play, the idea of getting off the mat when it has cooled to the 160 to 180 degrees F range isn’t always valid. Depending on stone structure, mix design, WMA additives, and so on, you may be able to roll in static mode when the mat temperature is cooling below 160.
Know your mix. Know your temperature. Know the fancy intelligent compaction system you’re working with and plug in all the parameters that can help you get a bonus-worthy mat.
Above all, create a test strip and have the QC/QA tech double-check your numbers. The tech helps you set up the perfect rolling train, complete with the temperature range to watch, when you place a test strip.
