Vibratory Roller Evaluation Study.

摘要

A research study is underway to evaluate the capabilities of vibratory rollers to compact asphaltic concrete pavements. The performance of these rollers was compared to relative density and surface smoothness criteria contained in Department specifications as well as results produced by conventional rolling methods. Although some of the vibratory rollers tested produced results somewhat better than others,overall it was determined that these machines could meet the requirements set forth in the specifications. General appearance of the pavement surface compacted by vibratory rollers was found to compare favorably with pavements compacted by static weight rollers. Surface ripples,undulations and other objectional features were not found to be a major problem on this particular project.
