RISFuzzy‐Bayesian Approach to Reliability of Existing Structures
Publisher: American Society of Civil Engineers
Abstract: Classical reliability has significantly enhanced the ability of engineers to assess the safety of constructed projects. It has been shown that Bayes' theorem is an effective tool in updating prior probabilities when the ...
Waterproof and Antiscour Properties of Asphalt-Based Composite Seals for Airfield Base Layer
Publisher: ASCE
Abstract: A new type of three-layer waterproof structure was developed to reduce the scour problem of concrete slabs by paving an asphalt-based composite seal layer between the cement-stabilized base and the cement concrete pavement. ...
Fatigue and Rutting Performance of Airfield SBS-Modified Binders Containing High Modulus and Antirutting Additives
Publisher: ASCE
Abstract: Permanent deformation and fatigue cracking are two main distresses on airfield pavement. To enhance material performances, the researchers introduced three additives in this study: namely, two high modulus agents (HM-1 and ...
Characterization of Fatigue Looseness of Dowel Bars Based on Substructure Experiment
Publisher: ASCE
Abstract: Dowel bars are indispensable parts of the concrete pavement for load transfer, but they become looser under repetitive load. Because the actual shape and magnitude of fatigue looseness of dowel bars were not observed well ...
Effect of Magnesium Ions on the Mechanical Properties of Soil Reinforced by Microbially Induced Carbonate Precipitation
Publisher: ASCE
Abstract: Microbially induced carbonate precipitation (MICP) is a new foundation treatment technology, which can improve the mechanical properties of soil. In this study, sand specimens containing different magnesium/calcium ion ...
Stochastic Analysis and Time-Dependent Reliability of Reinforced Concrete Beams Considering Spatially Distributed Corrosion Deterioration
Publisher: ASCE
Abstract: Reinforcement corrosion is an important part of durability research of concrete structures. The process of reinforcement corrosion is highly random due to various factors, and the effect of spatial distribution of reinforcement ...
Mechanisms on the Salt–Frost Scaling of Concrete
Publisher: American Society of Civil Engineers
Abstract: In this paper, the effects of NaCl concentration on saturation in concrete and ice-formation pressure and volume expansion of solutions are investigated; also, mechanisms of concrete salt-frost scaling are analyzed. Results ...

Salt-Frost Resistance Performance of Airfield Concrete Based on Meso-Structural Parameters
Publisher: American Society of Civil Engineers
Abstract: Airport cement pavement is prone to severe freeze–thaw damage due to the use of deicing chemicals. There is no unified evaluation parameter for analyzing the relationship between the concrete meso-structure and its salt-frost ...
Influences of Naphthenic Oil on SBS-Modified Asphalt Binder
Publisher: American Society of Civil Engineers
Abstract: As an organic solvent, naphthenic oil is used widely in the polymer industry, so it has the potential to be used with polymer to improve the performance of asphalt binder in pavement engineering. The effects of naphthenic ...
