Seal Coat and Surface Treatment Manual: Setting the Rock Lands

IntroductionPurposeCalculating The Length of Rock LandMarking The Rock LandsA rock land is the area covered, at the desired aggregate application rate, by one predetermined size truckload of aggregate. The area of the rock land is calculated in advance and marked either on the pavement with paint or on the side of the road with flags. Setting rock lands for strip/spot seal coat work is not necessary if less than one truckload of aggregate will be used in a particular area.

Tack Coat Guidelines

A tack coat is not required before placing a chip seal. However, some chip seals require a flush coat (fog seal and sand cover) on their surfaces. A tack coat is not generally required before a slurry seal or a micro-surfacing application unless the existing pavement surface is extremely dry and raveled or is concrete pavement.

Hanson’s conclusion was that, for a successful seal on a smooth surface, the rate of binder application should be such that the 20% of voids volume after trafficking became 70% filled with binder. He expressed this as a simple formula: Residual application rate R = ALD x 0.20 x 0.70 (Hanson’s Equation) or R = 0.14 ALD
