Abstract:

The Louisiana Department of Highways has in progress a two phase program to evaluate the use of vibratory rollers in the compaction of asphaltic concrete pavements. Phase one on the first construction project is now complete with eight different vibratory rollers having participated. Emphasis of the evaluation is centered upon two requirements contained in the Specifications: (1) relative roadway density and (2) surface smoothness. In addition, results obtained with the various vibratory rollers are compared with results produced by conventional rollers and rolling methods.

Findings indicate that vibratory rollers used alone are capable of replacing the three static weight rollers in the compaction process. Overall density and surface smoothness results compared closely with those obtained by conventional rolling methods and were found to meet specification requirements. It was, therefore, recommended and subsequently adopted by the Department the vibratory rollers be permitted as an alternate to conventional rollers on all existing and future construction projects involving the compaction of asphaltic concrete.
