For the past seven years, ADOT&PF Northern Region has been applying different dust-control palliatives to rural runways. The only guidance in applying these palliatives has come from the manufacturers, and these are too vague to be of much practical use. As the specifications are written, ADOT&PF has found it impossible to determine whether these products are meeting their own standards or not. This project, using UAF's new DUSTM instrumentation, is collecting data and comparing the effectiveness of newly laid palliative and palliative that has been applied one to three years earlier. From these results, researchers will develop a reasonable performance-based set of specifications that cover the application of dust-control palliatives to unpaved transportation surfaces. These specifications will make it possible for ADOT&PF to choose the best palliative for a community's needs, and hold vendors accountable for the quality of their products.
