RISDynamic Mechanics and Damage Evolution Characteristics of Rubber Cement Mortar under Different Curing Humidity Levels
Publisher: ASCE
Abstract: The dynamic compressive test of rubber cement mortar (RCM) under two different curing humidity levels (the relative humidity was 95% and 50%, respectively) was carried out by using a split Hopkinson pressure bar (SHPB) ...
Financial Consequences of Delaying Pavement Rehabilitation: Case Study Using LTPP Data
Publisher: American Society of Civil Engineers
Abstract: Transportation agencies have suffered stringent funding shortages for the past several years. As a result, many pavement preservation and rehabilitation projects have been substantially delayed. The financial consequences ...
Community Question in Transitional China, a Case Study of State-Led Urbanization in Shanghai
Publisher: American Society of Civil Engineers
Abstract: The community question, referring to the transformation of social networks when rural residents move into urban areas, has been extensively debated by urbanists and sociologists in Western countries. This paper, focusing ...
Impacts of Chinese Urbanization on Farmers’ Social Networks: Evidence from the Urbanization Led by Farmland Requisition in Shanghai
Publisher: American Society of Civil Engineers
Abstract: Following rapid urban expansion, numerous rural villages have been requisitioned for urban development in Chinese cities. During the prevailing urbanization process, displaced farmers within a village are wholly relocated ...

Microcrack Detection in Thermally Damaged Concrete Based on Broadband Frequency Coupling of Nonlinear Ultrasonic Modulation
Publisher: ASCE
Abstract: The initiation and development of microcracks (with width generally less than 100–150 μm) introduced by heating or fire plays a critical role in the stability and durability of concrete structures, especially for large ...
Durability Evaluation of Single-Component Polyurethane-Bonded Porous Mixtures
Publisher: ASCE
Abstract: Pavement service and antiaging performance of single-component polyurethane-bonded porous mixtures (PPMs) were studied. The influence of the adhesive–aggregate ratio on PPM volumetric properties and pavement service ...
Design Method of Asphalt Pavement Mixture Based on Performance Balance Approach
Publisher: ASCE
Abstract: In China, a large number of on-site investigations on the service conditions of asphalt pavements show that cracking has gradually become one of the most serious problems besides rutting. Part of the reason is that, in the ...
Optimal Sizing of an Air Vessel in a Long-Distance Water-Supply Pumping System Using the SQP Method
Publisher: American Society of Civil Engineers
Abstract: By optimizing the sizing of air vessels, not only is the damage from water hammer prevented, but also the cost of water hammer protection systems is minimized. This paper presents a numerical simulation of an air vessel ...
