Description
Since 1966 an evaluation project has been underway to study asphalt pavement by measuring its dielectric properties. Originally, this project was directed toward asphalt content, however, it was determined that asphalt density had a relationship to dielectric properties.

The goal of this research project is to evaluate the performance of the crumb rubber test sections compared with the conventional control section and depending on performance, develop Colorado-specific materials and construction specifications for ground tire modified asphalt pavements. Also, the research project aims to develop guidelines and best management practices for the construction of ground tire modified asphalt pavements. Transverse cracking...

Description
Roller Compacted Concrete (RCC) is a no-slump concrete mixture that is transported, placed, and compacted with the same construction equipment as asphalt pavement. After only nine months of service, the RCCs already showed noticeable changes in all of the selected properties tested. More tests and field inspections should be conducted in the future after a longer monitoring period to verify and validate the initial findings observed in the material...

The two objectives for this research were to review the 2016 asphalt mixture specifications to determine whether changes were warranted that could lead to more durable asphalt mixtures and, if so, adjust the specification accordingly and construct test sections to evaluate the revised specification.

The purpose of this report is to provide the reader with the ten-year analysis for the cost-benefit of hot mix asphalt projects constructed using the three and five-year warranty specifications developed by CDOT. There were eight projects evaluated using the three-year warranty specifications and two projects evaluated using the five-year warranty specifications. Each warranty project was evaluated with a comparable non-warranty (control) project....

Description
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...

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...
