What is the main purpose of a dust palliative?

The main purpose of a dust palliative is to minimize dust produced by traffic and wind. Dust palliatives are materials applied to surfaces to control dust emissions, particularly in areas where vehicles drive or where wind can carry loose particles. By binding the fine particles together, these palliatives effectively reduce airborne dust, improving air quality and visibility.

This is especially important in environments that experience heavy traffic or are naturally arid, as dust can lead to health issues, lower productivity, and potential regulatory challenges for air quality. The use of dust palliatives enhances safety and comfort for workers and the general public by mitigating dust-related problems.

While the other choices involve tasks related to construction and surface preparation, they do not directly address the primary function of dust palliatives, which is solely focused on dust suppression.
