High roughness

WebRoughness. Pavement roughness is generally defined as an expression of irregularities in the pavement surface that adversely affect the ride quality of a vehicle (and thus the user). Roughness is an important pavement characteristic because it affects not only ride quality but also vehicle delay costs, fuel consumption and maintenance costs. WebRoughness affects various part characteristics, including the amount of wear, the ability to form a seal when the part makes contact with something, and the ability to coat the part.
