Development of a Full-Depth Wheel Tracking Test for Asphalt Pavement Structure: Methods and Performance Evaluation

Table 6

Two typical structures of asphalt pavements in a flat slope section of an expressway.

Structure type	Structure layers	Materials	Gradation type
Structure I	Upper layer	Stone matrix asphalt mixture	SMA-13
	Middle layer	Asphalt mixture with antirutting cracking agent	AC-20C ( anticracking agent added)
	Bottom layer	Asphalt treated base	ATB-25
Structure II	Upper layer	SBS-modified fine-grained-type asphalt concrete	AC-13
	Middle layer	Asphalt mixture with antirutting cracking agent	AC-20C ( anticracking agent added)
	Bottom layer	Asphalt treated base	ATB-25
