ASPHALT ANTISTRIPPING ADDITIVES (DOPE)

PRODUCT

Pavegrip 550 is a concentrated 100% active liquid antistripping additive.  It's 100% active formulation makes this low odor, heat stable product a high performance additive that can help with even the most difficult mix designs.

It is well document through research that using additives will help prevent moisture damage. The use of an additive is recommended in all levels of the roadbed as moisture / water attacks from all sides:

. Surface water forced in by the weight of heavy vehicles
. From the side of the road bed due to poor side drainage
. From beneath the road as ground pressure pushes water up in to the road

This water is the bond breaker that leads to 
failure ! 

There are two major benefits to using liquid antistripping additives:

1) Increased adhesion improves performance, which increases the lifespan of the pavement - saving money long term in reduced maintenance.

The strength of the asphalts adhesion to the aggregate is measured using a test called the TSR test (Tensile Strength Ratio). Asphalt samples are compacted for testing in which one is set aside as is (the control) while the other is conditioned (a series of heating and freezing). A breaking head is used to measure the amount of pressure required to break the sample.

TSR = average conditioned strength / average control strength (Most agencies require a TSR minimum of 80%)

2) Another advantage to liquid additives is that they allow the use of less expensive aggregates

The ability to use less expensive aggregate reduces the overall cost per ton of mix - which provides significant savings!

Pavegrip - increase your performance, and reduce your costs !
