RUBBER MODIFIED ASPHALT COATING FOR ROOFING AND ROADS

Description
OBJECT: Dissolve butadiene crumb rubber into 1,000 gallons of asphalt at 360 degrees F.
PROBLEM: Crumb rubber tends to agglomerate and “golf ball sized” lumps take 24 hours to fully dissolve.
RESULTS: Lumps are ground down to minus ¼” in one pass through Dicon – recirculation grinds rubber down to 20 mesh (1/32” or 780 microns).
AB MIXER: Model 6 x 3 Dicon with heat tracing tape
BENEFIT: Complete dissolving occurs in one hour. Batches are now made on demand instead of “day before”.
EQUIPMENT REPLACED: Colloid mill
