RISImpact of Backfill Material on the Rerounding of Deflected Corrugated High-Density Polyethylene Drainage Pipes
Publisher: ASCE
Abstract: Rerounding is a technique for remediating excess deflection in thermoplastic pipe. A pneumatic device vibrates along the vertical axis and pushes against the inside crown and invert to restore the original pipe shape and ...
Early-Age Behavior of Internally Cured Concrete Bridge Deck under Environmental Loading
Publisher: ASCE
Abstract: The early-age cracking of bridge decks is a typical issue in the US that reduces service life. Internally cured (IC) concrete has been used in some states to reduce or eliminate the development of cracks in reinforced ...
Laboratory Evaluations of Corrugated HDPE Pipes Containing Postconsumer Recycled Material under Constant Deflection Conditions
Publisher: ASCE
Abstract: In recent years, incorporation of recycled material in the production of large-diameter plastic drainage pipes for nonagricultural purposes has gradually increased. With this new development, AASHTO began allowing corrugated ...
Field Inspection of Corrugated HDPE Pipeline Network under Heap Piles at a Copper Mine Site in Chile
Publisher: American Society of Civil Engineers
Abstract: In-service conditions of a corrugated high density polyethylene (HDPE) pipeline network embedded within a bioleaching pad in the Atacama Desert in Chile were assessed. The pipes provided air for the copper extraction process ...

Forensic Study on a Collapsed Structural Plate-Arch Culvert in Ohio
Publisher: American Society of Civil Engineers
Abstract: In April 2014, a large structural plate arch culvert collapsed in Licking County, Ohio. The structure’s demise appeared to be related to a slope failure experienced by the roadway embankment fill above the inlet section. ...
Performance Assessment of Unbonded Concrete Overlays of Concrete Pavements in Ohio: A Forensic Practice
Publisher: ASCE
Abstract: Unbonded concrete overlay (UBCO) is a widely used rehabilitation technique for deteriorated pavements, which is accomplished by placing concrete overlay on top of existing pavement with a sandwiched bond breaker layer ...
Bond Characteristics of CFRP Rod Panels Adhered to Concrete under Bending Effects
Publisher: American Society of Civil Engineers
Abstract: Carbon fiber–reinforced polymer (CFRP) rod panels (CRPs) comprising small-diameter rods at a spacing larger than rod diameter are emerging as an effective adhesively bonded system for retrofit applications. They offer the ...
Response of a Composite-Adjacent Box Beam Bridge with Skewed Beams under Static and Quasi-Static Loads
Publisher: American Society of Civil Engineers
Abstract: Adjacent box beams are widely used for constructing short- and medium-span bridges on roadways throughout the United States. The performance of a straight, noncomposite-adjacent box beam bridge under a live load is well ...
Long-Term Behavior Prediction of HDPE Containing Postconsumer Recycled Material Using Stepped Isostress Method
Publisher: ASCE
Abstract: To predict the long-term behavior of high-density polyethylene (HDPE) drainage pipes, HDPE coupon specimens with 0%, 49%, and 98% postconsumer recycled (PCR) material content were loaded incrementally in tension following ...
