Available in PDF, EPUB and Kindle. Book excerpt: Use of Controlled Low-Strength Material (CLSM) behind bridge abutments has become common practice to avoid the problem of settlement when using compacted soils. CLSM solves the settlement problem within the fill but raises separate concerns. The lateral pressures that CLSM exerts on the bridge abutment are not well understood. Another concern is the potential for clogging of the drainage material on the bridge abutment. This could occur if the fly ash, cement, or water paste flows through the drainage fabric and hardens. Research was performed in a series of laboratory tests and finite element analyses to determine the lateral pressures generated by CLSM. The effect of CLSM on drainage material was also evaluated in the physical tests. For the physical testing an apparatus was constructed that was six feet tall, two feet deep, and two feet wide.
Book Synopsis The Design and Application of Controlled Low-strength Materials (flowable Fill) by : Amster K. Howard
Download or read book The Design and Application of Controlled Low-strength Materials (flowable Fill) written by Amster K. Howard and published by ASTM International. This book was released on 1998 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focuses on a type of material mainly used in place of compacted backfill for pipe embedment and backfill, but gaining widely in applications. It is a mixture of cementitious material, soil, water, and sometimes fly ash and admixtures. Here 26 papers, from a June 1997 symposium in St. Louis, Missouri, describe new design procedures, new applications, and installation innovations in order to help assess the need for new or revised standards. They cover ingredients, properties, test methods, standards and specifications, case histories, and pipeline applications. The five current standards are appended.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Flowable fill or Controlled Low Strength Material (CLSM) is a self-compacted cementitious material used in the field in the place of compacted fill. It is also known as unshrinkable fill, controlled density fill, flowable mortar, plastic-soil cement, soil-cement slurry, and others. The advantages of this material include lesser soil settlements, elimination of compaction, and lower costs when compared to chemically treated and compacted subsoils. CLSMs have a wide range of applications such as using them as a backfill, bedding material, trench filling material, void filling material, bridge abutment and embankment materials and also in pavement bases. Current research is aimed at the design of CLSMs using native soils that can be used as bedding and backfilling materials to support a large pipeline project. Native soils were selected as fine material mainly due to excavation in the site will lead to large amounts of excavated fills and hence any reuse of this material will enhance sustainability components of the projects. This will also result in significant cost savings to the construction project. Several mix designs using native high plasticity clays were attempted to establish the optimum quantities of binders and water. Set accelerator was also used to lower the setting time of some of the mix designs. All these mix designs were evaluated for their flowability, density, compressive strength and setting time properties as per the available ASTM standards. Finally, six mix designs were formulated with setting time as limitation based on the property specifications for their use as a pipeline fill material at different zones. Test results and analysis indicates that high plasticity clay can be successfully used as aggregate in CLSM mixes. Further recommendations were made to study the durability of strengths achieved.

Book Synopsis Evaluation of Passive Force on Skewed Bridge Abutments with Controlled Low-strength Material Backfill by : Kevin Bjorn Wagstaff
Download or read book Evaluation of Passive Force on Skewed Bridge Abutments with Controlled Low-strength Material Backfill written by Kevin Bjorn Wagstaff and published by . This book was released on 2016 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: To determine the relationship of passive force versus backwall displacement for a CLSM backfilled bridge abutment, two laboratory large-scale lateral load tests were conducted at skew angles of 0 and 30°. The model backwall was a 4.13 ft (1.26 m) wide and 2 ft (0.61 m) tall reinforced concrete block skewed to either 0 or 30°. The passive force-displacement curves for the two tests were hyperbolic in shape, and the displacement required to reach the peak passive resistance was approximately 0.75-2% of the wall height. The effect of skew angle on the magnitude of passive resistance in the CLSM backfill was much less significant than for conventional backfill materials. However, within displacements of 4-5% of the backwall height, the passive force-displacement curve reached a relatively constant residual or ultimate strength. The residual strength ranged from 20-40% of the measured peak passive resistance. The failure plane did not follow the logarithmic spiral pattern as the conventional backfill materials did. Instead, the failure plane was nearly linear and the failed wedge was displaced more like a block with very low compressive strains.

Book Synopsis A Novel Abutment Construction Technique for Rapid Bridge Construction by : Sam Selwany
Download or read book A Novel Abutment Construction Technique for Rapid Bridge Construction written by Sam Selwany and published by . This book was released on 2012 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major obstacles facing rapid bridge construction for typical span type bridges is the time required to construct bridge abutments and foundations. This can be remedied by using the controlled low strength materials (CLSM) bridge abutment. The CLSM bridge abutment comprises full-height precast concrete panels attached to a CLSM backfill via epoxy-coated steel anchors. The main objective of this study is to examine the application of the CLSM bridge system in typical span type bridges used in railroad and highway situations. To do so, an instrumented, large-scale laboratory test was performed on a CLSM bridge abutment to investigate its performance due to the application of a monotonically increasing sill (foundation) pressure. The test results show that the CLSM bridge abutment, with a relatively short cure time of 7 days, is capable of carrying bridge loads with a reasonably large safety margin, and with minimal deformations.

Download or read book Flowable Fill Backfill for Use in Sequential Excavations in Contaminated Soil written by Ash, JR. and published by . This book was released on 1998 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of controlled low-strength materials (CLSM) or flowable fill for backfill of pipelines and adjacent to structures has become common practice because of ease of placement, lack of need for compaction, and relatively fast set time of the material. These properties are also ideal for backfill placed underwater or fill placed to allow sequential excavation.

Download or read book Construction of CLSM Approach Embankment to Minimize the Bump at the End of the Bridge written by JM. Benson and published by . This book was released on 1998 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oklahoma Department of Transportation and Oklahoma State University School of Civil and Environmental Engineering are currently conducting a research program to evaluate options to minimize approach embankment settlement. The research program involves construction of three new bridges on U.S. 177 north of Stillwater, Oklahoma. Five of the six approach embankments/abutment backfills were constructed using different construction materials and methods. The constructed approach embankments include: unclassified borrow (control section), geotextile reinforced wall, controlled low strength material, dynamically compacted granular backfill, and flooded/vibrated granular backfill. The approach embankments/abutment backfills have beeninstrumented to measure earth pressure on the abutment walls, settlement and lateral movement of the approach embankments, and groundwater conditions. The paper documents the design and construction of the CLSM approach embankment and reviews the instrumentation data collected to date.
