Digital Image Analysis in Geotechnical Engineering Education
Publisher: American Society of Civil Engineers
Abstract: Existing research has shown that visual input significantly contributes to learning, therefore, it is paramount to use visual tools to help demonstrate engineering concepts. One of these tools, digital image analysis, can ...
Class F Fly-Ash-Amended Soils as Highway Base Materials
Publisher: American Society of Civil Engineers
Abstract: Class F fly ash cannot be used alone in soil stabilization applications as it is not self-cementing. An activator such as Portland cement or lime must be added to produce cementitious products often called pozzolan stabilized ...
Sepiolite as an Alternative Liner Material in Municipal Solid Waste Landfills
Publisher: American Society of Civil Engineers
Abstract: Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is ...
Dynamic Effects on Moisture Transport in Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: Permeability of an asphalt pavement is one of the most important parameters that have a direct influence on its design life. It is an intrinsic property that relates the average fluid velocity to a constant pressure gradient; ...
Effects of Fines Content on Hydraulic and Mechanical Performance of Unbound Granular Base Aggregates
Publisher: ASCE
Abstract: The fines content of a granular aggregate base (GAB) material (<0.074 mm) is highly variable and often related to the crushing process, transportation, and stockpiling in a quarry or site. The influence of fines content ...
Effect of pH and Subgrade Type on Trace-Metal Leaching from Steel-Slag Embankments into Groundwater
Publisher: American Society of Civil Engineers
Abstract: An experimental research program was carried out to evaluate the environmental impacts of embankments constructed with steel slag on groundwater. A series of sequential water leach tests and sequential column leach tests ...
Geoenvironmental Evaluation of RCA-Stabilized Dredged Marine Sediments as Embankment Material
Publisher: ASCE
Abstract: Millions of cubic meters of marine sediment are dredged from Chesapeake Bay waters in Maryland each year. Due to their low-strength characteristics, the sediments often need to be amended with other geomaterials for potential ...
Soluble Salts Reduction and Metal Leaching Behavior of Dredged Sediment for Reuse in Highway Slope Applications
Publisher: ASCE
Abstract: Ports and waterways are routinely dredged to maintain navigation channels, resulting in large quantities of dredged materials (DM) that require disposal. This study examines the reuse of a recent DM as a topsoil alternative ...
Compost for Permanent Vegetation Establishment and Erosion Control along Highway Embankments
Publisher: ASCE
Abstract: Erosion management is a major environmental challenge facing highway construction. A research study was undertaken to analyze possible sustainable improvements to current standard procedures for final grade turfgrass ...
Shear and Hydraulic Properties of Compost-Amended Topsoils for Use on Highway Slopes
Publisher: ASCE
Abstract: The amount of municipal solid waste (MSW) generated in the US increases every year, and about 30% of the MSW generated is either recyclable or compostable. Utilization of compost-amended topsoils as a vegetative layer on ...
