Which types of distresses can be treated with surface treatments?

Surface treatments are primarily designed to address early signs of distress, particularly those that do not indicate severe structural damage. Raveling and minor cracking are typical examples of distresses that surface treatments effectively address.

Raveling occurs when the aggregate particles in the asphalt mix begin to come loose and displace, which can lead to further degradation of the surface if not treated. Surface treatments, such as chip seals or seal coats, can help bind these loose aggregates and restore the integrity of the pavement surface, preventing further raveling.

Minor cracking is also a distress that can be managed through surface treatments. These treatments help seal the cracks, preventing moisture infiltration, which can lead to more significant issues if allowed to progress. By applying a seal coat or similar treatment, maintenance crews can extend the life of the pavement and improve ride quality without the need for extensive repairs.

In contrast, options mentioning deep potholes, heavy rutting, or major cracking indicate more severe forms of pavement distress. These issues often require structural repairs or the replacement of sections of the pavement rather than just a surface treatment.
