Installation of chip seal driveways costs about $2 to $5 per square foot, based on site conditions, stone type and color, labor costs, oil prices, and the number of seals required.It costs $1 to $3 per square foot to resurface a gravel or asphalt driveway with tar and chip.. Cost Per Mile Of Chip Seal Roads. A private one-lane tar and chip road cost will range from $20 to $60 per linear foot.
A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the emulsion and aggregates represents "slurry.".

Two slurry products can be distinguished - Slurry seal and microsurfacing. Slurry seal is normally laid no thicker than 1½ times the top size of the aggregate, which can range from 3-10 mm. Mineral fillers like cement or hydrated lime are commonly used, but are not always required. Slurry seals waterproof and seal the surface from water
Generally, Type I slurry seals are used in parking lots and Type II and III seals are used on streets and higher traffic roads. Slurry seals will fill small surface cracks, stop raveling, and improve the skid resistance of the pavement. Advantages The surface of a slurry-seal treatment is smoother than a chip seal …
