Description
Colorado Department of Transportation (CDOT) does not have evidence how the Dynamic Cone Penetrometer (DCP) test results correlate to other test methods (say, R-value) for Colorado's pavement subgrade. Even, the correlation between single-mass, and dual-mass DCP (which are two ways of conducting DCP test) is still unknown. Pavement Mechanistic Empirical Design (PMED) guide provides some correlations among different subgrade tests. However, those correlation...

Description
This study investigates the dynamic modulus of Cold-in-Place Recycling (CIR) pavement material and its performance using pavement performance data, field testing, laboratory testing, and Pavement Mechanistic-Empirical Design Guide (PMED) software analysis. Colorado Department of Transportation (CDOT) has 37 projects with over 8 million square yards using CIR materials. Sites from ten projects were selected to monitor the performances, and collect...

Description
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.
