A series of field reports by the Planning and Research Division of the Colorado Department of Highways, beginning in May 1978 and ending in October 1978 on two different projects on recycling hot mix bituminous pavement. One project reported on was on I-80 west of Laramie, Wyoming. The second set of reports are on a recycling project outside of Buena Vista, Colorado. Includes discussion on methods and equipment used and the results of the various...

Cold recycling technologies such as Full-Depth Reclamation (FDR) are sustainable and cost-effective techniques for pavement rehabilitation. Previous research has found current mechanistic-empirical (M-E) default values to be non representative and overly conservative, leading to an underestimation of the true performance capabilities of FDR materials. To address this gap, this research analyzes the performance of 11 FDR sites constructed throughout...

Colorado Department of Transportation (CDOT) has dynamic modulus (E*), and flow number (N) database of different mixes from different regions of Colorado. The sensitivities of these mixes considering factors such as mix types, aggregates source, volumetric properties, contractors, preparation times, binders, etc. on E*, and N, and on the pavement performances are investigated in this study.
