Failing asphalt pavements deserve a second look
DON’T REPAVE UNTIL YOU KNOW WHY!
Every pavement contractor’s worst nightmare occurs when an unhappy client calls to report a problem. Whether it’s potholes, alligator cracks, edge cracks, slippage cracks, rutting, raveling or depressions, these signs of asphalt failure can certainly send you and your bottom line into a deep depression.
Airport authorities win with an ultra-effective asphalt interlayer design that’s quick, long-term AND cost effective
In 2019, the Taylor County Airport in Kentucky needed a long-term solution for its failing runway. The BATT Lab developed a new solution for an easy-install interlayer.
Got aggregate? Get friction testing before you pave.
Friction testing provides a quick method to rank potential sources of aggregate. Recently, our clients have used friction testing to investigate potential non-polishing alternate aggregate sources for submission to DOT for consideration. Yet there are other reasons to consider it.
BATT Lab earns AASHTO accreditation
The binder laboratory within Blankenship Asphalt Tech and Training (BATT Lab) has passed rigorous third-party assessments to receive accreditation from the AASHTO Accreditation Program (AAP).

How much does density matter?
Why do we want more density in a pavement? Density is the unit weight of a mixture. This article looks at various methods for testing density and provides results that show an increase in pavement density results in a positive effect on the overall pavement performance.

Environmental Product Declaration (EPD)
FHWA Superb Guidance Document
This EDP tech brief by FHWA is a superb document that explains and outlines the EDP process.
State Departments of Transportation (DOTs) are continually assessing and choosing materials or technologies to meet their transportation needs. As part of this assessment, DOTs are turning to Environmental Product Declarations (EPDs) to quantify the environmental impacts associated with those products.
