RISNeural Network–Swarm Intelligence Hybrid Nonlinear Optimization Algorithm for Pavement Moduli Back-Calculation
Publisher: American Society of Civil Engineers
Abstract: This paper describes a novel hybrid intelligent system approach to inversion of nondestructive pavement deflection data and back-calculation of nonlinear stress-dependent pavement layer moduli. Particle swarm optimization ...
Global Optimization of Pavement Structural Parameters during Back-Calculation Using Hybrid Shuffled Complex Evolution Algorithm
Publisher: American Society of Civil Engineers
Abstract: In this paper, the use of a hybrid evolutionary optimization algorithm is proposed for global optimization of pavement structural parameters through inverse modeling. Shuffled complex evolution (SCE) is a population-based ...
Support Vector Machines Approach to HMA Stiffness Prediction
Publisher: American Society of Civil Engineers
Abstract: The application of artificial intelligence (AI) techniques to engineering has increased tremendously over the last decade. Support vector machine (SVM) is one efficient AI technique based on statistical learning theory. ...
Pavement Life-Cycle Sustainability Assessment and Interpretation Using a Novel Qualitative Decision Procedure
Publisher: American Society of Civil Engineers
Abstract: A novel approach to life-cycle sustainability (impact) assessment and interpretation procedure on the basis of multiple criteria is developed in this paper for the comparison and evaluation of alternative road pavement ...
Neural Networks Modeling of Stress Growth in Asphalt Overlays due to Load and Thermal Effects during Reflection Cracking
Publisher: American Society of Civil Engineers
Abstract: Although several techniques have been introduced to reduce reflective cracking, one of the primary forms of distress in hot-mix asphalt (HMA) overlays of flexible and rigid pavements, the underlying mechanism and causes ...
Structural Characterization of Iowa’s Rubblized PCC Pavements
Publisher: American Society of Civil Engineers
Abstract: Rubblization is considered one of the sustainable surface preparation techniques before placing a hot mix asphalt (HMA) overlay that involves breaking the concrete pavement into pieces. The design of the structural overlay ...
Moisture Susceptibility of Subgrade Soils Stabilized by Lignin-Based Renewable Energy Coproduct
Publisher: American Society of Civil Engineers
Abstract: Sustainable use of biomass as a renewable source of energy can be an alternative solution to the cost of fossil-based energy and global warming. Production of biofuel from plant biomass results not only in bio-based energy, ...
Capillary Transport in RCC: Water-to-Cement Ratio, Strength, and Freeze-Thaw Resistance
Publisher: American Society of Civil Engineers
Abstract: Water transport plays a critical role in the freeze-thaw (F-T) response of concrete. This work aims at appreciating various water transport parameters in roller-compacted concrete (RCC) for different pavement applications ...
