Dataset regarding the mechanical properties of roads unbound treated with synthetic fluid based on isoalkane and tall oil.

The dataset revolves around the laboratory testing of an innovative additive technology for possible stabilization of unbound courses in road pavements. The product is a synthetic fluid based on isoalkane and tall oil pitch. Two test types are performed. Repeated load triaxial tests evaluate the elastic stiffness and the deformation properties of both untreated and treated aggregates. Moreover, some specimens are also tested before and after being subjected to freezing-thawing actions. A modified version of the rolling bottle test appraises the integrity with stripping loss on loose aggregates covered by the additive. Considering the necessity for road maintenance and rehabilitation worldwide, experimental data dealing with the stabilization potential of an innovative synthetic fluid stabilizer can be relevant for several road stakeholders.

Managing Alaska's Road-Dust Problem: A Model for Road Dust-Impacted Regions.

Poor air quality in Alaska's remote communities due to road dust is one of the top environmental concerns of residents in these communities. Most communities are disconnected from the road network, with community roads that are predominantly unpaved. In Alaska, high costs limit widespread paving of roads, leaving communities to rely on alternative dust control strategies. The goals for this study were to assess the magnitude and impact of the dust problem in rural Alaska and use a diversity of experience, including regulatory, research, engineering, and cultural, to develop a road-dust management approach for rural Alaska. The plan incorporates different levels of dust management: institutional controls, road watering, chemical dust suppressants, and road surface stabilization. Geographical zones where use of each different dust management level will be most appropriate are identified based on rainfall frequency. Approximately 50% of Alaska's communities can manage road dust with institutional controls and road watering. Many of the road-dust management ideas presented are transferable to other global regions that experience similar economic and community access challenges as Alaska.
