Abstract: The short-term physical response of a 1.5-mm-thick, high-density polyethylene geomembrane with an artificially formed wrinkle and overlying three different subgrade materials (sand and compacted clay at two initial water ...

Abstract: Experimental results from physical testing are reported to examine the thickness and hydraulic performance of three geosynthetic clay liners (GCLs) overlying a geonet when subjected to vertical stresses (e.g., as may be ...

Abstract: High-density polyethylene (HDPE) pipes are subjected to tensile stresses and strains in the axial direction during and after a pulled-in-place installation by horizontal directional drilling or pipe bursting. During these ...

Abstract: High-density polyethylene (HDPE) pipelines are commonly installed using horizontal directional drilling (HDD), a trenchless construction technique used to replace or expand underground pipelines which generates cyclic axial ...

Abstract: A semiempirical approach to estimate liquefaction-induced lateral displacements using standard penetration test (SPT) or cone penetration test (CPT) data is presented. The approach combines available SPT- and CPT-based ...

Abstract: Results from full-scale physical experiments are reported to identify and quantify short-term lateral response around the perimeter of a modular polymer stormwater collection structure during backfilling and under applied ...

Abstract: Results from full-scale physical experiments are reported to quantify the column forces that develop in a modular, polymer stormwater collection structure when buried at its minimum soil cover and subjected to design-truck ...

Abstract: Accelerated aging tests to evaluate the depletion of antioxidants from a high density polyethylene geomembrane are described. The effects of temperature, high pressure, and continuous leachate circulation on the aging of ...

Abstract: Wrinkles are buckles or waves that develop from restrained thermal expansion when the geomembrane is left exposed to solar heating. Wrinkles can substantially reduce the effectiveness of the geomembrane as a hydraulic ...
