Filter by Keyword25 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... Routine bridge inspections in the United States are primarily conducted via visual inspection on a fixed two-year cycle. Although this strategy has generally produced a safe bridge network, a variety of research has been conducted to study enhanced inspection planning processes that could more efficiently... This report documents the effort to develop a practical relation between the cracking tolerance index and portions of the dynamic modulus curves of asphalt mixtures. A review of practices used to create asphalt mixtures dynamic modulus master curves, based on NCHRP reports and other relevant literature... This report describes the research efforts aimed at determining the repeatability of the IDEAL-CT test for use as part of the balanced asphalt mix design process. Three mixes in common production in northern Utah were investigated by three different labs experienced in performance testing. Within-lab... 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... |
