Asphalt Paving
Asphalt Paving
(OP)
We finished laying asphalt (BM 25.0) on Saturday. During the operation everything was done and tested according to VDOT (Roller pattern, control strip, etc). We took core samples the same day and they were test by noon of the following day. I just got the results of the density test performed on the samples and non of the samples met the required 95% density. What options do we have to correct this problem?





RE: Asphalt Paving
If the density is significantly off, you might require the contractor to mill and overlay.
How low was the density? Was the density in the field compared to lab density or a control strip density? What size cores were used? Do you know if the testing was performed properly?
What do you think caused the low density? Was it placed too cold? Was the equipment too light or did break-down rolling not occur quickly enough? Was the mix design "off". Is this a "SuperPave" mix?
