Evaluation of Cold Central-Plant Recycling (CCPR) Technique Using Full-Scale Accelerated Pavement Testing

Two test pavement sections (four test cells) with cold central plant recycling (CCPR) as base layers were constructed at the Virginia Accelerated Pavement Testing facility to investigate the optimal overlay thickness on CCPR base layer in 2015. The two test sections had similar structures but different thicknesses of surface layer: 76 mm and 38 mm (3 and 1.5 in.). Pavement sections were instrumented with strain gauges and pressure cells. The strain and pressure responses were collected and analyzed. By comparing the pressure distributions at different depths, it was found that the pressure in subbase of lane 2 is much higher than that in lane 1 because of the thinner surface layer. The distribution of pressure versus depth showed that the thinner surface layer led to a steeper reduction of pressure in surface and CCPR layers, which could mean increased rutting over time.
