The objective of this study was to evaluate the effect of typical chemical winter maintenance practices on Arizona Department of Transportation pavements. A review of previous studies on the effect of deicing/anti‐icing chemicals did not yield definitive recommendations, especially for DIAICs typically used by ADOT. Researchers conducted a laboratory study evaluating the effects of magnesium chloride, potassium chloride, sodium chloride, and distilled water on eight different open‐graded rubber‐modified asphalt concrete mixes using the boiling test. All experimental factors were found to be statistically significant, and the researchers provide recommendations on which DIAICs should be used for different binder and aggregate types.

Tourism is one of 12 industry clusters widely considered to be driving the Arizona economy according to the Governor’s Strategic Partnership for Economic Development (GSPED). The term "cluster" refers to a geographic concentration of interdependent companies, suppliers, products, labor pool, and institutions that together constitute an important competitive advantage for a region. In northern Arizona, tourism ranks as the predominant industry cluster. This paper provides a profile of the tourism cluster in Coconino County, with special focus on the Flagstaff area. It examines the cluster’s composition, relative size and importance to the regional economy. It addresses the cluster’s dynamics and requirements for growth. It reviews important national and worldwide trends affecting tourism in Arizona, as well as the special characteristics of gateway communities. And, finally, it presents a menu of actions to choose from for strengthening the cluster in both Flagstaff and Coconino County.

The Governor's Strategic Partnership for Economic Development has identified 12 industry clusters in Arizona that collectively drive the economy. The term "cluster" refers to a geographic concentration of interdependent companies, suppliers, products, labor pool, and institutions that together constitute an important competitive advantage for a region. Tourism is recognized as one of Arizona's 12 industry clusters. In northern Arizona it ranks as the dominant cluster.

Much of the analysis in this report is based on the concept that industry clusters act as primary growth influences on local economies. Strong clusters produce goods or services that can be sold to consumers outside the region, creating a flow of revenue into the region. This influx of revenue stimulates economic activity in other areas of the local economy such as the retail, real estate, or constructions sectors.

This report profiles the tourism cluster in Coconino County with special focus on the Page area. It examines the cluster's composition, relative size, and importance to the regional economy, and it addresses the cluster's dynamics and requirements for growth. In its conclusion, it presents a menu of options for strengthening the cluster in the Page area.
