WHITE PAINT FOR HIGHWAY THAW SETTLEMENT CONTROL
Roads built on permafrost are often difficult to maintain because of permafrost melt induced settlement caused by black pavement absorbing more sunlight than a lighter-colored surface. One way to counteract this would be to point the pavement white to reflect more sunlight measurements of several short painting pavement sections between Fairbanks and Delta, Alaska, show that this does indeed reduce settlement. However, there are some grave drawbacks: the cost of applying paint, safety (i.e. increase slipperiness and snow sticking and frost forming sooner on the cooler surface), and settlement continuing near unpainted shoulders even though the center of the road is protected.
