A sand seal is a spray application of asphalt emulsion followed with a light covering of fine aggregate, such as a clean sand or screenings. Although this is a simple operation, it can be useful in correcting a number of pavement flaws. Emulsion is usually sprayed between 0.7 l/m2 to 1.25 l/m2 and sand is placed at 5.5 kg/m2 to 12 kg/m2 as a cover.
