Frequently Asked Questions
We’ve answered the most common questions we get about going FRAP Ready. If you don’t see your question here, call 1-800-545-2125 or contact us here.
WHY FRACTIONATE RAP?
Any recycled product is worth at least as much as what it replaces. But, if the material is processed and treated like virgin material, its value can be enhanced. By fractionating reclaimed asphalt, operators can use a higher percentage of RAP, helping to lower costs while maintaining a high-quality asphalt mix.
WHY HIGH-FREQUENCY SCREENING?
It is well known that coarse material requires more amplitude and less frequency, while fine material requires less amplitude and more frequency. The high frequency screen focuses on this fact by using an aggressive vibration applied directly to the screen media with almost no amplitude being applied to the screen box sides. The high RPM rate allows material to stratify and separate at a much faster rate. This produces more efficient sizing for finer material, as compared to conventional screens.
WHY AN HSI CRUSHER?
Unlike compression crushing, impact crushing minimizes material buildup, making HSI crushers the most suitable design for fractionating reclaimed asphalt pavement (RAP). An HSI crusher configured with a high-frequency screening plant creates the ultimate in FRAP processing.
WHY KPI-JCI and ASTEC MOBILE SCREENS?
Only with an HSI Crusher from KPI-JCI and Astec Mobile Screens can operators use as much as a 50% FRAP mix. From HSI crushing equipment to High-Frequency Screens to Non-Segregating Stacking Conveyors, KPI-JCI and Astec Mobile Screens give you the widest product selection on the market. And, our product specialists are available to help solve complicated applications, explain the ROI of our product lines and provide the educational tools you need to be profitable. We are a part of the Astec family, a household name in the world of asphalt.
