Filter by Keyword22 report(s) found with cracking in the keywords field The condition of concrete on bridge decks is one of the most costly parts of Wyoming Department of Transportation's budget and the cost of maintenance can result in inadequate roads or costly premature repairs. This proposal evaluates critical factors relating to early age shrinkage and proposes combining... This document presents the continuous effort to develop mechanical tests that can relate to the expected performance of asphalt mixtures once placed in the field. During a previous research project, asphalt mixtures of different compositions were collected from different locations across the state of... Asphalt mixtures were collected from seven field projects and distributed to different laboratories to determine their potential for cracking. Samples were prepared in the lab for testing at two conditions: low, in-service temperatures using the bending beam rheometer device based on AASHTO TP-125 and... A study was conducted in which cores were taken from pavements three years after construction. The flexibility index (FI) of the cores, a parameter that relates to intermediate temperature cracking, was measured in the lab and compared to the known values of the same material obtained during constructions.... An evaluation of CRCP was conducted in order to determine the extent of possible corrosion of CRCP on selected interstates in South Dakota. General observations showed there were sections of severe and localized reinforcement corrosion at some crack locations. Crack mapping, chloride tests profiles... The use of deicing salts on highway bridges has decreased the service life of bridge decks due to the accelerated corrosion of the steel reinforcement. The use of Glass Fiber Reinforced Polymer (GFRP) in bridge decks as a means of corrosion-mitigation has been met with some success; however, GFRP is... Fourteen Thin Lift Treatments (TLTs) in Utah's Department of Transportation (UDOT) Region 2 were evaluated over a five-year period in order to assess their performance. Surface distress data was quantified using Pavement Condition Indices (PCIs), and Remaining Service Life (RSL) were estimated following... An evaluation of the ability of the BBR (Bending Beam Rheometer) as a test to determine changes in the low temperature properties of asphalt mixture parameters was conducted, along with the possible implications of adopting this test for low temperature pavement performance. It was found that the creep... Steel bridges with reinforced concrete substructures and steel superstructures are considered to have superior performance under earthquakes when compared with their reinforced concrete counterpart. Such performance reputation stems from the fact that few steel bridges have been subjected to strong ground... The use of Carbon Fiber Reinforced Polymers (CFRP) for the repair of civil infrastructure has been on the rise. Most studies have focused on the effect of CFRP to increase the stiffness and strength of reinforced concrete beams or columns. Limited attention has been given to the effect of CFRP on mitigating... |
