Available in PDF, EPUB and Kindle. Book excerpt: This report describes the post-construction evaluation of the fast track pavement in Sterling, Colorado. The field evaluation consisted of visual inspection, fault measurement, profile measurement and distress survey. A set of falling weight deflectometer (FWD) measurements was also acquired to assess the structural responses and to evaluate load transfer efficiency between the slabs. The results of this study demonstrated that fast track concrete can be as durable as the conventional concrete pavement. After seven years of being in service the pavement has shown no sign of fatigue, only some minor distresses unrelated to fast track techniques.

Download or read book Investigation of the Rutting Performance of Pavements in Colorado written by Timothy Aschenbrener and published by . This book was released on 1992 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the rutting performance from plastic flow on 33 hot mix asphalt (HMA) pavements was performed. Air voids in the wheel path of 3.0% clearly distinguished pavements with good and bad rutting performance: air voids less than 3% rutted and air voids greater than 3% did not rut from plastic flow. Samples were recompacted in the Texas gyratory using the high and low efforts. Samples recompacted with air voids greater than 2.0% with the high effort or 3.0% with the low effort indicated good performance with respect to rutting. The air voids after the low effort of compaction correlated best with the air voids in the wheel path for high volume roadways. Component properties (aggregates, asphalt cements, gradation, etc.) did not reveal why the good pavements performed well and the bad pavements did poorly. Performance was directly tied to the void properties. Field verification should be performed throughout the project to provide indications of the future rutting performance of the pavements.

This book was released on 2004 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of reinforced concrete structures has been a significant problem for many state and transportation agencies since the application of deicing salts was introduced. Much research has been conducted to develop corrosion protection systems that can prolong the life span of reinforced concrete structures. The Colorado Department of Transportation (CDOT) has several routine and experimental measures to prevent corrosion of the rebar including epoxy-coated rebar, calcium nitrite admixture, organic corrosion inhibitors, a thick cover of quality concrete, and a waterproofing membrane covered by an asphalt overlay. An extensive literature review was performed to collect information on various corrosion protection systems that have been used in the U.S. and around the world. Current CDOT practices in terms of corrosion protection measures were reviewed. A draft inspection plan for Colorado's bridge structures was proposed.

Book excerpt: Large-stone hot mix asphalt (HMA) pavements have been promoted by various associations including the National Asphalt Pavement Association (NAPA) as an answer to rutting problems which exist with current pavement design. Until 1988 the Colorado Department of Transportation (CDOT) had little or no experience with the advantages or disadvantages of large-stone HMA pavements. This report investigates problems encountered in the construction of three large-stone HMA construction projects. Problems encountered with large-stone HMA include segregation of the mix and the validity of mix designs produced with standard test equipment. The study examined the following: the lab tests in use by the CDOT for large-stone pavements, constructability, field performance, and cost required to produce the mix.
