58 As can be seen in Table 22, the primary AM techniques identified by NCHRP Report 420 and the two additional techniques added or modified by the NCHRP Project 03-120 research team are the ones most likely to have documented effects. It can also be seen that more knowledge exists for the effects of AM techniques on the motorized vehicle mode than on other roadway modes.
