RISEstimating Maximum Bending Moment in High-Density Polyethylene Pipes under Traffic Loading
Publisher: ASCE
Abstract: High-density polyethylene (HDPE) pipes have been widely adopted for municipal pipeline projects all over the world. HDPE pipe failures, including reduced flow capacity and wall buckling, have been reported extensively, and ...
Effect of Polymer Amendment on Hydraulic Conductivity of Bentonite in Calcium Chloride Solutions
Publisher: ASCE
Abstract: Hydraulic conductivity of polyanionic cellulose (PAC)–amended bentonite (PB) in calcium chloride (CaCl2) solutions was investigated to access its chemical compatibility in vertical cutoff walls application. PB was synthesized ...
Shear Behavior of Biochar-Amended Biocemented Calcareous Sand Treated by Biostimulation
Publisher: American Society of Civil Engineers
Abstract: Biostimulated microbially induced carbonate precipitation (MICP) is an innovative soil improvement approach utilizing indigenous ureolytic microbes to hydrolyze urea. The objective of this study is to investigate the effect ...
Experimental Study of the Effects Produced by a Backfilling Process on Full-Scale Buried Corrugated HDPE Pipes in Fine-Grained Soils
Publisher: American Society of Civil Engineers
Abstract: High-density polyethylene (HDPE) pipes are widely used throughout the world due to their significant advantages. Most of the previous studies have focused on the behavior of the pipe-soil system under live loading and the ...
Laboratory Evaluation of Ladle Furnace Slag in Unbound Pavement-Base/Subbase Applications
Publisher: American Society of Civil Engineers
Deep Mixing Induced Property Changes in Surrounding Sensitive Marine Clays
Publisher: American Society of Civil Engineers
Abstract: This paper presents a field study of installation effects of deep mixed columns on properties of the sensitive Ariake marine clay. Cone penetration tests were performed in the field to evaluate the change in the strength ...

Evaluation of Cement Hydration Properties of Cement-Stabilized Lead-Contaminated Soils Using Electrical Resistivity Measurement
Publisher: American Society of Civil Engineers
Abstract: In this study, electrical resistivity was related to the fundamental geotechnical properties of cement solidified/stabilized heavy metal–contaminated soils. Lead-contaminated soils were artificially prepared with various ...
Hydraulic Conductivity of Sand/Biopolymer-Amended Bentonite Backfills in Vertical Cutoff Walls Permeated with Lead Solutions
Publisher: ASCE
Abstract: This study investigated the hydraulic conductivity and microscopic properties of two backfills, conventional sand/bentonite (SB) and sand/xanthan gum (XG)-amended bentonite/sand (XG-SB), for use in vertical cutoff walls ...
Hydraulic Conductivity, Microstructure, and Compositional Changes of Sand–Bentonite Backfill in Cutoff Walls Exposed to Organic Acids
Publisher: ASCE
Abstract: Leachate, consisting of organic acids such as acetic acid (AA) and oxalic acid (OA), commonly is released into groundwater from municipal solid waste dumps and uncontrolled landfills. Slurry trench cutoff walls commonly ...
