In recent years dust has become a major concern in Alaskan villages. Dust sources include river sand bars, borrow pits, streets and roads and airports. Residents of the villages are calling for a reduction of dust due the health concerns. Respiratory illnesses including asthma are increasing due to poor air quality. Over a decade ago, DOT&PF began looking at the use of dust palliatives to reduce dust coming from the airports.
A study by UAF showed that synthetic fluids are a cost-effective means of managing that dust. However, there was no means of selecting which products were effective and no means of selecting the appropriate application rate except for the manufacturer's suggested application rates.
UAF developed the Dust Column test which measures the effectiveness of palliatives Working with the ADOT&PF's materials sections, UAF and Statewide Materials Section developed an Alaska Test Method aimed at ensuring the right palliative is selected along with the right application rate. This webinar will discuss the development of the test method, how it can be used and an overview of what's next.
