Description
Leandro Harries, Stefan Böhm, and Jia Liu test paver settings in field trials in a 2026 study. Asphalt pavers use a screed with tamper and vibratory units to pre-compact fresh pavement. Two field trials used a set paver and roller with one asphalt mix, and lab tests checked thickness, density, voids, and surface roughness.
Tamper speed clearly shaped layer thickness and compaction degree, while vibratory speed showed no real effect. Void distribution stayed highly even, above 98 percent, across pre-compacted areas. Surface roughness tended to fall as tamper speed rose. The authors advise keeping tamper changes minimal and switching vibration off for this mix.
