Figure 20. Standard Groove Profiles for T5, North I PHASE TWO SUMMARY. In Phase Two of this research, a small series of trapezoidal-shaped grooves were cut in a pavement test section in the NAPTF. The objective of this laboratory test area evaluation was to observe and compare the construction process and deformation response over time of the two subject groove geometries when trafficked under heavy aircraft loads.
