RISDiscussion of “<i>Drained Permanent Deformation of Sand Due to Cyclic Loading</i>” by Ching S. Chang and Robert V. Whitman (October, 1988, Vol. 114, No. 10)
Publisher: American Society of Civil Engineers
Three-Dimensional Characterization and Simulation of Anisotropic Soil Fabric
Publisher: American Society of Civil Engineers
Abstract: A procedure for constructing resin impregnated sand specimens for fabric (microstructure) analysis is presented. The impregnation device provides excellent control of the impregnation rate and confinement for different ...
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 ...
Evaluation of the Effects of Waste Engine Oil on the Rheological Properties of Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: This study evaluated the feasibility of using waste engine oil (WEO) to partially replace virgin asphalt binder. Two base asphalt binders (PG 64-28 and PG 76-22) were blended with three different WEO percentages of , 5, ...
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 ...
Modification of Asphalt Materials to Resist Studded-Tire Wear on Pavements
Publisher: ASCE
Abstract: Studded tires are used during winter seasons to reduce snow- and ice-related accidents in several cold climate regions. However, during driving the studs in these tires progressively punch into the asphalt pavement and ...
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 ...
Void Fabric Tensor and Ultimate State Surface of Soils
Publisher: American Society of Civil Engineers
Abstract: This paper presents a method to characterize the fabric of soils. Attention is focused on the directional distribution of voids in these materials. The mean porosity and void fabric tensor used in the description are ...
