RISWork Zone Planning in Pavement Rehabilitation: Integrating Cost, Duration, and User Effects
Publisher: American Society of Civil Engineers
Abstract: This paper describes a methodology developed to support decision makers in planning work zones for pavement maintenance and rehabilitation interventions, integrating cost, duration, and user effects. The methodology relies ...
Modeling Tidal Current Profiles by Means of Empirical Orthogonal Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The method of empirical orthogonal functions (EOFs) is used to model vertical velocity profiles of the current. The whole current field is decomposed into time series of along and cross-slope ...
Discussion of “<i>Construction and Performance of Two Large rockfill embankments</i>” by Gordon M. Matheson and William F. Parent (December, 1989, Vol. 115, No. 12)

Factors Limiting the Progression of Internal Erosion in Zoned Dams: Flow Limiting by an Upstream Material
Publisher: American Society of Civil Engineers
Abstract: In zoned dams, some types of materials, when located upstream of a damaged core, may impose high hydraulic losses capable of limiting the flows converging toward the flaw in the core. In this paper, the factors influencing ...
Statistical Modeling of Carbonation in Concrete Incorporating Recycled Aggregates
Publisher: American Society of Civil Engineers
Abstract: Durability and recycling are two major concerns in the construction industry. Concrete carbonation may impair reinforced concrete durability as it favors the onset of reinforcement corrosion. The use of recycled aggregates, ...
Mechanical Characterization of Lightweight Expanded Clay Aggregate Materials for Modeling Their Geotechnical Behavior
Publisher: American Society of Civil Engineers
Abstract: Based on an extensive testing program, this study presents the mechanical behavior of a lightweight expanded clay aggregate (LWA). This material is currently being used in many civil engineering works and particularly in ...
Probabilistic Lifetime-Oriented Multiobjective Optimization of Bridge Maintenance: Combination of Maintenance Types
Publisher: American Society of Civil Engineers
Abstract: In this paper, the performance of deteriorating bridges is analyzed considering the combination of essential and preventive maintenance actions. Multiobjective optimization under uncertainty is used to find the best ...
Processes Involved in the Formation and Performance of Self-Hardening Slurry Walls: Santa Clara-a-Velha Monastery Cutoff Wall
Publisher: American Society of Civil Engineers
Abstract: Several different phenomena are involved in the formation and performance of self-hardening slurry walls, including slurry contamination by soil, penetration of slurry into the ground, confining with the trench, filtration, ...
A New Design of Vehicle Seat Intended to Alleviate Lower Back Pain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The novelty in the proposed seat design consists in allowing a free vertical motion of the back rest, so as to decrease the strain on the spinal column. Road and vibrating table tests show ...
