What can prevent short waves in asphalt paving?

Maintaining a consistent mix at the head of the screed is crucial for preventing short waves in asphalt paving. Short waves often occur due to variations in the material properties, such as aggregate size or temperature, leading to uneven distribution and compaction as the asphalt is laid. By ensuring the mix is consistent, the asphalt will spread evenly across the surface, minimizing the likelihood of these surface imperfections. A uniform mix ensures that all elements of the asphalt, including bitumen and aggregates, work together cohesively during the paving process, leading to a smoother final surface.

Other factors like roller speed, mix thickness, and material temperature can also influence the quality of the asphalt layer, but they do not address the root cause of inconsistency directly related to mix uniformity at the screed.
