RISUse of Material Interfaces in DEM to Simulate Soil Fracture Propagation in Mode I Cracking
Publisher: American Society of Civil Engineers
Abstract: Mode I fracture is common in geomechanics in desiccation cracking, hydraulic fracture, and pressuremeter testing. The cohesive crack model has been used extensively and successfully in numerical modeling of such fracture ...
Evaluating the Effectiveness of Pavement Preventive-Maintenance Treatments in Mitigating Longitudinal Cracks in Wet-Freeze Climatic Zones
Publisher: ASCE
Abstract: Preventive-maintenance treatments are increasingly being adopted in pavement preservation during recent years. For such treatments to be effective, their selection must be based on the right conditions. This study quantifies ...
Pore Structure Models to Predict Hydraulic Conductivity of Recycled Asphalt Pavements
Publisher: American Society of Civil Engineers
Abstract: Recycled asphalt pavement (RAP) is increasingly being used due to the economic savings and environmental benefits. RAP contains removed or reprocessed asphalt binder and aggregates instead of virgin material. In order to ...
Evaluating Cost Effectiveness and Optimal Timing of Pavement Preventive-Maintenance Treatments in Wet-Freeze Climates
Publisher: ASCE
Abstract: Preventive-maintenance treatments help preserve pavements and delay deterioration caused by traffic loads and environmental conditions. However, guidance is needed to ensure cost effectiveness of treatments, the benefit-to-cost ...
Evaluating Performance Jumps for Pavement Preventive Maintenance Treatments in Wet Freeze Climates Using Artificial Neural Network
Publisher: ASCE
Abstract: Preventive maintenance treatments are extensively used due to their active cost-effectiveness, and evaluating their short-term effectiveness is an important criterion. In this study, the performance jump, which is defined ...
Evaluating Cracking Deterioration of Preventive Maintenance–Treated Pavements Using Machine Learning
Publisher: ASCE
Abstract: Preventive maintenance treatments are extensively used in pavements due to their many benefits, including lowering life-cycle costs. Although the effectiveness of preventive treatments has been evaluated, many highway ...
Numerical Modeling of Desiccation Cracking Using the Cohesive Crack Method
Publisher: American Society of Civil Engineers
Abstract: With the advent of climate change, it is thought that desiccation cracking of soil will lead to increases in damage to buried infrastructure. Desiccation cracking is a complex phenomenon that historically has been very ...
Use of Digital Image Modeling for Evaluation of Concrete Pavement Macrotexture and Wear
Publisher: American Society of Civil Engineers
Abstract: Modeling of the pavement image formation process by using reflection properties of macrotexture showed that digital images of concrete pavements can be used to monitor pavement wear. The specific optical characteristics ...
Modeling of Crack Depths in Digital Images of Concrete Pavements Using Optical Reflection Properties
Publisher: American Society of Civil Engineers
Abstract: Digital image-based automated pavement crack detection and classification technology has seen vast improvements in the recent years. Although crack lengths and widths can be evaluated using state-of-the-art software with ...
Effect of Characteristic Lengths of Fracture on Thermal Crack Patterns
Publisher: American Society of Civil Engineers
Abstract: Approximately uniformly spaced cracking occurs in many different materials and processes during thermal or drying shrinkage. Such cracks may occur when a slab of material restrained at the bottom is subjected to a sudden ...
