RISAlternative Approach for Predicting the Phase Angle Characteristics of Asphalt Concrete Mixtures Based on Recurrent Neural Networks
Publisher: ASCE
Abstract: Laboratory performance testing of the phase angle of asphalt concrete (AC) mixtures is often expensive and requires enormous human effort and time. To circumvent this problem, several regression-based methods have been ...
Optimal Performance Threshold Determination for Highway Asset Interventions: Analytical Framework and Application
Publisher: American Society of Civil Engineers
Abstract: Civil asset managers continue to seek appropriate thresholds of asset performance for applying standard interventions. Recognizing that between the two extremes of profligacy and parsimony there exists a certain optimal ...
Effect of Temperature on Fatigue Crack Growth in CPVC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study addresses the effect of temperature on fatigue crack growth (FCG) behavior of CPVC. FCG tests were conducted on CPVC SEN tensile specimens in the temperature range −10 to 70°C. ...
Dynamic Multimodal Response of Bender Element Transmitter
Publisher: ASCE
Abstract: The response of a bender transmitter to sinusoidal excitations in air, liquids, and transparent soil is investigated using a novel laser vibrometer technique. The purpose of the study is to investigate how benders vibrate ...
Downscaling Based Identification of Nonaging Power-Law Creep of Cement Hydrates
Publisher: American Society of Civil Engineers
Abstract: Creep of cementitious materials results from the viscoelastic behavior of the reaction products of cement and water, called hydrates. In the present paper, a single isochoric creep function characterizing well-saturated ...
Scale and Condition Economies in Asset Preservation Cost Functions: Case Study Involving Flexible Pavement Treatments
Publisher: American Society of Civil Engineers
Abstract: Estimates of planning-level treatment costs are vital inputs for preservation project budgeting, prioritization, and programming in highway asset management. However, with the paucity of analytical research on highway asset ...
Empirical Correlation of Permanent Deformation Tests for Evaluating the Rutting Response of Conventional Asphaltic Concrete Mixtures
Publisher: American Society of Civil Engineers
Abstract: Rutting or permanent deformation is one of the severe distresses manifested in flexible pavements caused by the various mechanisms such as densification, lateral plastic flow, and/or loss of materials under wheel path due ...
Evaluating the Cost Effectiveness of Flexible Rehabilitation Treatments Using Different Performance Criteria
Publisher: American Society of Civil Engineers
Abstract: At a certain point in the life of a flexible pavement, rehabilitation is required to improve pavement condition and to defer reconstruction. Pavement managers seek the best rehabilitation treatment on the basis of cost ...
How Water-Aggregate Interactions Affect Concrete Creep: Multiscale Analysis
Publisher:
Abstract: Customary micromechanics models for the poroelasticity, creep, and strength of concrete restrict the domain affected by the hydration reaction to the cement paste volume, considering the latter as a thermodynamically closed ...
Influence of Coarse-Aggregate Angularity on Asphalt Mixture Macroperformance: Skid Resistance, High-Temperature, and Compaction Performance
Publisher: ASCE
Abstract: Macroperformance, i.e., skid resistance, high-temperature, and compaction performance, are related to the functional performance, safety, and durability of asphalt pavement. Currently, the research on such influencing ...
