MINERAL ROAD FIBERS V. CELLULOSE ROAD FIBERS


COST COMPARISON WHEN ABSORPTION TAKEN INTO ACCOUNT

Before cellulose can act as a stabilizer of the asphalt in an SMA or OGFC mix, it must be completely saturated with asphalt. The amount of asphalt required to saturate 6 pounds (0.3% dosage rate) of cellulose averages 0.4% more asphalt than if mineral fibers were used. This additional asphalt does not increase the film thickness around the aggregate. Mineral fiber, which is made primarily of stone, does not absorb asphalt.

An SMA or OGFC mix using mineral fiber will contain 6 to 6.2% asphalt in the mix. SMA and OGFC mixes using cellulose fiber will average 6.4 to 6.6% asphalt in the mix. At 6% asphalt per ton of mix, it would require 120 LB of asphalt (oil) per ton of mix when using mineral fibers. At 6.4% asphalt per ton of mix, when using cellulose fibers, a contractor would be required to use a minimum of 128 LB of asphalt (oil) per ton of mix.

So what is the biggest draw to using cellulose? It doesn't itch when it gets on your skin like mineral fiber. This is a big deal for some contractors. It also comes in easy to handle 40 LB bags, so you don't need a fork lift when loading the metering device.

Moreover, where there is only one mix design and thus one asphalt percentage considered, you are going to use less cellulose than mineral fiber.

Whatever your preference, cellulose or mineral, Fiberand has you covered. There is no schedule and or quantity we can't keep up with or supply.

Call us and we'll be glad to send you samples of cellulose and or mineral fiber for mix designs.
