RISDevelopment of a Damage-Based Phenomenological Fatigue Model for Asphalt Pavements
Publisher: American Society of Civil Engineers
Abstract: Bottom-up fatigue cracking is one of the major distresses for asphalt pavements. Accurate prediction of fatigue cracking for asphalt pavement is of paramount importance for a cost-effective pavement design. A fatigue model ...
Modeling and Visualization of Underground Structures
Publisher: American Society of Civil Engineers
Abstract: Based on the solid modeling, transformation operation and Boolean operation techniques widely available in computer-aided design and drafting system, first, this paper proposed a general modeling method for dynamic underground ...
Selection of Preoverlay Repair Methods for Asphalt Overlay on Asphaltic and Composite Pavements in Wisconsin Based on Cost Effectiveness
Publisher: American Society of Civil Engineers
Abstract: Asphalt concrete (AC) overlay is a commonly used rehabilitation technology for existing distressed pavements. Current practice regarding the selection of preoverlay repair is based on the experience of designers and field ...
Effects of Preoverlay Pavement Conditions and Preoverlay Repair Methods on the Performance of Asphaltic Concrete Overlays
Publisher: American Society of Civil Engineers
Abstract: Asphaltic concrete overlay is a commonly used rehabilitation technology for existing asphaltic or concrete pavements. The existing pavements are often repaired prior to the placement of the overlay. Considering the significant ...
Comparative Study on the Small Radius Curved Bridge and Simplified Models by Shaking Table Tests
Publisher: ASCE
Abstract: Three experimental structural models of a small radius curved bridge, which include a three-span small radius curved bridge model and its corresponding two different simplified models that are widely used (e.g., one mass ...
Double Punch Test: Simple Performance Test to Evaluate the Fatigue and Rutting Potential of Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: The primary distresses of the asphalt pavement are rutting, fatigue cracking, and thermal cracking. Laboratory tests can be conducted to characterize the expected performance of asphalt concrete in the field. This study ...
Modeling and Prediction of the Effects of Moisture on the Unconfined Compressive and Tensile Strength of Soils
Publisher: American Society of Civil Engineers
Abstract: Unconfined compressive strength (UCS) and tensile strength are important geomaterial parameters that are used for performance prediction and mix design. Both UCS and tensile strength are affected by gravimetric water content ...
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 ...
Influence of Guide Ring on Energy Loss in a Multistage Centrifugal Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multistage centrifugal pumps are highly efficient and compact in structure. Pump efficiency can be improved by an effective understanding of hydraulic behavior and energy loss, however, the traditional hydraulic loss ...
A Snake-Inspired Swallowing Robot Based on Hoberman’s Linkages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To solve the problems of existing swallowing robots, such as low load capacity, small deploy/fold ratio, and small swallowing space, this article presents a new snake-inspired swallowing robot (SSR) that can synchronously ...
