PlusRide and Bonifibers Pavement Evaluation: SR-530, Stanwood Vicinity

Description: Asphalt mixes modified with the addition of reclaimed rubber granules (PlusRide) and polyester fibers (BoniFibers) were used in a 0.12-ft. overlay of a badly distressed section of AC pavement. The distress consisted of transverse and longitudinal cracking which was reflecting through from the underlying old PCC pavement and severe alligator cracking which was an age related fatigue problem. A section of standard Class B dense graded ACP was also put down to serve as a control section for judging performance. 

The three sections are to be monitored over a period of three years to determine the effectiveness of the asphalt additive products in preventing the reflection of the distresses noted in the underlying pavement from showing through in the overlay. The first year inspection revealed that the PlusRide section was showing some longitudinal cracking over the old PCC lane edge. The BoniFibers section was also showing the same longitudinal distress over the lane edge of the underlying PCC plus a small amount of transverse cracking.
