From page 1...
... The ABQT project was identified and scoped jointly by FHWA and Laser Technology, Inc., while they were jointly researching related laser testing technologies. Thus, the ABQT development project was a spinoff of related research funded by FHWA and a collaborative development effort by the principals from this work.

From page 2...
... The FHWA investment to date has been approximately $400,000. If adop tion of the ABQT meets the levels specified in Scenario 3, the maximum adoption scenario, the net annual benefits over the 15-year life expectancy of the ABQT device would be about $10 million.

... These parameters are ones that drive the probabilistic model that was used to calculate the annual benefits of using the ABQT device: • The effectiveness of the ABQT device, • The percentage of samples collected by state DOTs that are tested (with the remaining samples not tested) , • The percentage of tested-failed samples that do not have an adverse effect on paved roads, and • The percentage of increased maintenance costs from using an out-of-specification binder.

... S.4  Significance and Promoting Adoption If adopted by stakeholders in the binder/asphalt sector, primarily state DOTs, the ABQT has the potential to deliver measurable reductions in the cost of maintenance for asphalt roads throughout the United States. At about $38,000, the device is relatively low cost.
