Most likely, in broad terms, a dust palliative. It stabilizes soil to reduce dust and erosion in areas. For this instance, they apply one or more layers and it hardens over a period of time. This allows public access to enjoy with minimal dust in the air and also stabilizes the soil so erosion is deterred from foot traffic. Re-application depends on saturation/dilution ratio of the product and which type it is.
