Drive-On Bond Coat Additive
Drive-On lives up to its name – by adjusting the quantity of additive, set times may be reduced to as low as 15 seconds, creating a track-free surface for paving crew shoes and public vehicles in just a few rolling cycles.
A more fluid product, Drive-On is easier to spray, gets fuller coverage, and makes clean up less of a headache than thicker alternatives.
These viscosity improvements also make Drive-On safer. To achieve similar levels of performance, a heavily modified tack coat can reach temperatures as high as 430˚F, up to 100˚ - 200˚ hotter than Drive-On modified PG asphalt.
And, in testing at NCAT, Drive-On showed superior bond strength in wet conditions - another potential time saver.
SIMPLER MATERIALS HANDLING AND LOWER COSTS
Using Drive-On additive may eliminate the need for high shear asphalt mixes, harder pen binders, and/or elevated quantities of polymer.
The additive technology is simple - the product can be produced in a plant or onsite in a distributor. A base PG asphalt binder is the only requirement, the additive disperses relatively easily with agitation, and one product works for all levels of modification.
During long term fatigue testing at NCAT, binders modified with the active adhesion technology in Drive-On showed no reduction in ductility, flexibility or elastic recovery, handling three times more loading cycles versus the competing product.
Additionally, fatigue, rutting and shear bond testing at NCAT demonstrated improved bond strength when the additive was applied to a PG64 binder, and field reports suggest the method achieves superior compaction without the mat shoving forward.
In addition to creating issues during application, our competitors' high viscosity technologies have zero flexibility, zero ductility and poor elastic recovery, making them brittle and prone to problems.
- Return leftover product to the binder tank or store it up to 3 years.
- Drive-On is already approved by a number of DOT’s.
