This paper describes the compaction of AE-concrete pavement having 30cm in depth by a surface vibrator.
The test results are summarized as follows:
(1) It is possible to consolidate AE-concrete having 30cm in depth with a surface vibrator by choosing the optimum vibrating condition for each mix proportion of concrete.
(2) The optimum condition of compaction by a surface vibrator seems to have good correlation with the settlement time measured by the consistency test with a vibrator used for road concrete.
(3) As the optimum condition, the frequency of 7000vpm and the acceleration of 20g are found to be suitable for the concrete having the settlement time of 25sec., the frequency of 5000vpm and the acceleration of 15g for the one with the settlement time of 15sec., and the acceleration of more than 5g and the amplitude of 0.6 to 1.4mm for the one with the settlement time below 10sec.
