What's a Hairline Crack?| Concrete Construction Magazine .

Although this definition doesn't give a numerical value for width (or require the viewer to wear bifocals to see the crack), it probably applies to cracks less than about 0.003 inch (0.08 mm) in width. Hairline cracks can be very shallow or quite deep, depending on the cause. However, there is no way to determine crack depth based on crack width.

Best Practices Handbook on Asphalt Pavement Maintenance

'The most common flexible pavement distresses are cracking, roughness, weathering, raveling, rutting and bleeding. If the distresses identified in a pavement are related to structural deficiencies, the pavement section is most likely not a candidate for preventive maintenance treatment, and should be scheduled for rehabilitation or reconstruction.

Those Cracks on the Edge of the Road.What Causes Them?

As the crack gets longer it eventually turns toward the outer edge of the pavement, making the characteristic "C" shape. It doesn't turn inward because the pavement is more resistant to cracking in that direction. It doesn't run parallel to the pavement edge because at some point the support gets stronger, and so the crack turns outward.
