Quantitative Model of Coagulation with Inorganic Polymer Flocculant PACl: Application of the PCNM
Publisher: American Society of Civil Engineers
Abstract: In this paper, a quantitative model of coagulation with inorganic polymer flocculants (IPFs) was investigated, using polyauminum chloride (PACl) as an example. Application of a modified precipitation charge-neutralization ...
Performance and Thermal Evaluation of Incorporating Waste Ceramic Aggregates in Wearing Layer of Asphalt Pavement
Publisher: American Society of Civil Engineers
Abstract: Industry waste materials are commonly used in road engineering. In this study, crushed ceramic waste aggregates (CWAs) were utilized and added into asphalt mixtures to investigate their potential usage. A finite-element ...
Analytical Calculations for Asphalt Pavement Considering Interlayer Performance
Publisher: ASCE
Abstract: Asphalt pavement structures are composed of layered materials and are assumed to be completely continuous elastic layered systems in structural design. However, a number of studies have indicated that the interface is not ...
Lessons Learned from the Damaged Huilan Interchange in the 2008 Wenchuan Earthquake
Publisher: American Society of Civil Engineers
Abstract: A disastrous earthquake struck Wenchuan in China’s Sichuan province in 2008 and caused heavy casualties and structural damage to bridges and buildings. One of the two severely earthquake-damaged curved bridges in China, ...
Fast and Accurate Method for Calculating the Surface Mechanical Responses of Asphalt Pavements
Publisher: ASCE
Abstract: Since the linear elastic layered theory was developed in 1940s, it has been widely used to evaluate asphalt pavement soundness, and the mechanical responses have been used to analyze the bearing capacity of pavement ...
Pavement Mechanics Calculation Based on the Analytical Solution of Layered Viscoelastic System under Horizontal and Vertical Loads
Publisher: ASCE
Abstract: Most countries adopt the mechanical theory of a layered elastic system under vertical load as the design method for asphalt pavement. This calculation theory does not consider the influence of the horizontal force of the ...
Hybrid Treatment Process of using MIEX and High Performance Composite Coagulant for DOM and Bromide Removal
Publisher: American Society of Civil Engineers
Abstract: Dissolved organic matter (DOM) and bromide, two primary precursors of disinfection by-products, cannot be effectively removed by conventional coagulation processes. Alternative methods are required to ensure the safety of ...
