This paper’s purpose is to provide an update on the pavement condition of MnROAD’s three low volume road (LVR) Superpave test cells constructed in 1999 with different asphalt binders, see table below. These cells were built to field validate the current low temperature performance grading (PG) system currently being used at Mn/DOT and many other agencies around the world. The paper will document the mix designs, laboratory testing, forensics, environmental conditions, and the resulting distresses observed include rutting, transverse cracking, fatigue cracking and how they are affecting pavement performance and ride.
