The National Center for Asphalt Technology (NCAT) has undertaken a wide range of hot mix asphalt (HMA) related research projects. These projects have been funded by various agencies such as the National Cooperative Highway Research Program (NCHRP) of the Transportation Research Board, the Federal Highway Administration (FHWA), the Alabama Department of Transportation, the South Carolina Departm...
The National Center f’or Asphalt Trchnolofiy (NCAT) has just complctd two Nation;ll Coopwrrive HicThw:tv Rr<e:lrch Pq!ram (NtHR6) Projects: NCHRP 9-X. “Designing Stone Matrix Asphalt (SMA) Mixtures.” and NCHRP 9-9. “Reilnement of Superpave Gyratory Compaction Procedure.” Dr. Ray Brown. NCAT director. was the p r i n c i p a l invcsti:etor on both pmjects. The fint project on SMA represented ;I ...
Computerized neurocognitive assessment tools (NCATs) are increasingly used for baseline and post-concussion assessments. To date, NCATs have not demonstrated strong test-retest reliabilities. Most studies have used non-military populations and different methodologies, complicating the determination of the utility of NCATs in military populations. The test-retest reliability of four NCATs (Autom...
introduction: due to the large number of pet systems available in the market, it is not very easy to decide about the scanner of choice. conducting a research in order to compare all different pet scanners is very time consuming and expensive and practically impossible. however, such comparison may be conducted using pet simulators. in this study, the performance of 6 different pet scanners in ...
—Continued on Pg. 2 The new Preservation Group (PG) experiment will provide answers for cash-strapped state and local agencies that need cost-effective ways to maintain existing asphalt roadways. Budgets are tight, but agencies still have the same task: keeping aging pavements in good condition for the driving public. When applied at the right time, pavement preservation treatments, such as chi...
Experimental economists currently lack a convention for how to pay subjects in experiments with multiple tasks. We provide a theoretical framework for analyzing this question. Assuming monotonicity (dominated gambles are never chosen) and nothing else, we prove that paying for one randomly-chosen problem—the random problem selection (RPS) mechanism—is (usually) the only incentive compatible mec...
