Comparison of Colorado component hot mix asphalt materials with some European specifications
Comparison of Colorado component hot mix asphalt materials with some European specifications
The purpose of the report is to identify differences in Colorado's aggregates and asphalt cements as measured and compared to some of the European tests and specifications. Performance-related tests for asphalt cements developed by SHRP will be the ultimate method to identify performance and should be well received in Europe. Based upon the standard empirical tests on asphalt cements from four refineries commonly used in Colorado, the asphalt cements are comparable to those used in France. The 17 most frequently used aggregate sources in Colorado were tested for the study. The angularity of fine aggregates is measured with the NAA test procedure. The quality of the P200 is measured with respect to angularity, durability, and stiffening., Timothy Aschenbrener., Technical Report number: CDOT-DTD-R-92-14., In cooperation with the Federal Highway Administration., "December 1992.", Includes bibliographical references (leaves 39-40)., Final report., Print version record.
Comparison of results obtained from the French rutting tester with pavements of known field performance
Comparison of results obtained from the French rutting tester with pavements of known field performance
The French rutting tester has been used successfully in France to eliminate the occurrence of rutting. The Colorado Department of Transportation (CDOT) and the Turner-Fairbank Highway Research Center (TFHRC) were selected to demonstrate this equipment. Thirty-three sites across Colorado with good and poor performance and a variety of temperature and traffic conditions were selected. Test results indicated that the French rutting tester, using the French specifications, was overly severe for many of the temperature and environmental conditions encountered in Colorado. However, by adjusting the testing temperature to match the highest temperature at a site location, the French rutting tester did an excellent job of predicting pavement performance. The results from the French rutting tester also had good correlation with actual rutting depths when temperature and traffic levels were considered., Timothy Aschenbrener., In cooperation with the Federal Highway Administration., Technical Report number: CDOT-DTD-R-92-11., "October 1992.", Includes bibliographical references (leaf 28)., Final report., Print version record.

Comprehensive evaluation of pavement maintenance activities applied to Colorado low-volume paved roads. Phase II
Comprehensive evaluation of pavement maintenance activities applied to Colorado low-volume paved roads. Phase II
The Colorado Department of Transportation (CDOT) has been trying to identify the most effective methods for managing low-volume roads (LVRs). These roads are facing multiple challenges including: reductions in maintenance budgets, impact of industrial activities, and potentially not receiving the most cost effective treatments. Considerable savings can be secured by implementing an effective and informed management system for all LVRs engineering issues, including: planning, design, and maintenance., Marwan Hafez, Khaled Ksaibati, Rebecca Atadero., "February 2018.", Report No. CDOT-2018-04, Online resource; title from PDF cover (viewed August 2019)

Construction and design soil property correlation
Construction and design soil property correlation
Proper structural design of pavement systems requires knowing the resilient modulus of the soil as this parameter is a proven predictor of the stress-dependent elastic modulus of soil materials under traffic loading. In addition, the R-value test is conducted using a device called a stabilometer, where the material's resistance to deformation is expressed as a function of the ratio of the transmitted lateral pressure to that of the applied vertical pressure. Both tests are expensive and time consuming; however, establishing accurate and reliable correlations between the test results and the soil's physical properties, in lieu of laboratory testing, can save a considerable amount of time and money in the analysis and quality control process. For these reasons, correlations are typically used for estimating the resilient modulus and R-value for soils. The variability of a given soil type in different regions and states requires developing modified and specific correlations for each state based on statistical analysis of the statewide soil data collected. The main goal of this research study was to develop correlations among R-value, Resilient modulus, and soil's basic properties for available AASHTO soil types in databases in Colorado., by Cara Fragomeni, Ahmadreza Hedayat., "July 2020.", "Report No. CDOT-2020-10" --Cover., "Report no. 2020-07." --Title page., "Prepared in cooperation with the US Department of Transportation, Federal Highway Administration.", Bibliography: pages 92-94., Online resource; title from PDF cover (viewed January 2021), Final report.

Construction cost forecast model : model documentation and technical notes
This report contains the documentation and supporting technical notes for a statistical model that estimates changes in the price components of the Colorado Construction Cost Index. The model contains two specifications. In the first, the composite construction index is a function of the producer prices of inputs: oil, concrete, steel, labor and equipment. In the second, the composite construction index is a function of the price of oil, wages and nationwide demand for construction services. Implementation The model has been transferred to Colorado Department of Transportation (CDOT)'s economist, who will maintain and operate it to forecast price inflation in construction costs over a thirty-year period, in support of statewide planning and programming., Peter Mills., Model operating and maintenance instructions -- Technical notes -- Appendices., Performed by Dye Management Group, Inc., sponsored by Colorado Department of Transportation., "Prepared in cooperation with the US Department of Transportation, Federal Highway Administration"--Technical report documentation page., "May 2013.", Includes bibliographical references., Online resource; title from PDF cover (viewed March 2016), Final report.

Core subject lesson plans: kindergarten through 8th grade
Core subject lesson plans: kindergarten through 8th grade
As recently as 1969 about half the school aged children in the United States walked or bicycled to school. Today fewer than 15% of school children walk or bike to school and as much as 20-30% of morning traffic is generated by parents driving their children to school. Children are less active today and the majority of children living within a 1/2 mile of schools are driven in private vehicles. Obesity rates are on the rise and the cost of obesity and other health related challenges have significant impacts on the rising cost of health care in the Unites States, not to mention the lifestyles of our children. In response to these challenges, in an effort to encourage healthy living, the Colorado Department of Transportation has developed a series of pedestrian and bicycle safety lesson plans in support of the Colorado Safe Routes to School program. These lesson plans, which help educators teach children about safe walking and bicycling, introduce a variety of skills that can help children stay safe while they walk by teaching them skills that will help them safely cross the street. Statistics show that child pedestrians are disproportionately represented in injury crashes and that the typical factors in those crashes that can be mitigated by education and practice., Online resource; title from PDF cover (viewed November 2016)
