Which of the following is a remedy for surface deformation?

Surface deformation is about unevenness in the pavement, such as rutting and high spots, that makes the surface rough and unsafe. The remedy that best fits this is a process that first levels the surface and then fills in the low areas to restore a smooth, even surface. Surface profiling unifies the surface by removing the irregularities to the proper grade. Milling the defective layer physically cuts away the deformed asphalt and any underlayers that are contributing to the roughness. After profiling, rut filling specifically targets wheel-path depressions, bringing those low areas back up to the surrounding level so the surface can compact evenly. Together, these steps restore smoothness and prevent future distortion, making the ride quality and structural performance better. Route and seal is designed to seal cracks to prevent water intrusion, not to correct overall surface smoothness. Patch and overlay can fix isolated potholes or local damage, but it doesn’t adequately address pervasive deformation across the surface and can leave underlying issues uncorrected. Weathering is natural deterioration over time and is not a repair method. So, the combination of surface profiling, removing the defective layer, and filling rutting directly targets and corrects the uneven surface, making it the most effective remedy for surface deformation.
