(2006 [11]) found that for a milled surface “the absence of tack coat did not significantly affect the bond strength at the interface”, which suggests that a rough milled surface provides significantly more shear resistance than a tack coat can add. Findings from Cooley (1999 [7]) and Sholar et al. (2002 [1]) support this view.
