Abstract:A regional chip sealing project installed test sections of very rapid setting emulsions (CVRS-2P) to determine if the curing time of the chip seal could be shortened as compared to conventional chip seals using CRS-2P binders. The test sections cured very rapidly allowing initial brooming to be completed in less than 25 minutes following placement and opening to posted speed operation in less than 3 hours after the brooming. This is in contrast to control sections of conventional chip seals using CRS-2P binders, which required 8 to 12 hours of reduced speed curing before final brooming and opening to posted speed operation.
