  • Hydrometer and Viscosity Cup Guide

    Hydrometer and Viscosity Cup Guide

    Hydrometers Do Work What Is Specific Gravity? Specific gravity of any solid or liquid substance is its weight compared with the weight of an equal bulk of pure water at 62 degrees F at sea level. Gases use an equal volume of pure air at 32 degrees F. There are three methods of determining the specific gravity of liquids: Hydrometer In which the specific gravity of the liquid tested is read as the scale division marking the liquid level on the stem. Bottle Method In which the specific gravity is the weight of liquid (slip) in a full bottle divided by the weight of water in a full bottle. Displacement Method In which specific gravity is the weight of liquid displaced by a body divided by the weight of an equal volume of water displaced by the same body. The first two methods are practical. The faster, easier method uses a hydrometer designed specifically for slip (see right). There are many different hydrometers. Slip should range between 1.78 to 1.75, the latter being the maximum amount of water in the body and the former the lesser amount. How To Get An Accurate Reading 1. Store hydrometer in water. This keeps slip from drying on the surface. A cut off two liter soft drink bottle is ideal. Remove and gently “squeegee” off excess water. 2. Immerse in freshly agitated slip to the stem readings. 3. Lift up, “squeegee” off excess slip. Hydrometer is now “wet coated” with slip, not with water, which would give a false reading. 4. Immerse bulb half way into slip before releasing.
  • Assessment of Pavement Foundation Stiffness Using Cyclic Plate Load Test

    Assessment of Pavement Foundation Stiffness Using Cyclic Plate Load Test

    Assessment of Pavement Foundation Stiffness using Cyclic Plate Load Test Mark H. Wayne & Jayhyun Kwon Tensar International Corporation, Alpharetta, U.S.A. David J. White R.L. Handy Associate Professor of Civil Engineering, Department of Civil, Construction, and Environmental Engineering, Iowa State University, Ames, Iowa ABSTRACT: The quality of the pavement foundation layer is critical in performance and sustainability of the pavement. Over the years, various soil modification or stabilization methods were developed to achieve sufficient bearing performance of soft subgrade. Geogrid, through its openings, confine aggre- gates and forms a stabilized composite layer of aggregate fill and geogrid. This mechanically stabilized layer is used to provide a stable foundation layer for roadways. Traditional density-based QC plans and associated QA test methods such as nuclear density gauge are limited in their ability to assess stiffness of stabilized composite layers. In North America, non-destructive testing methods, such as falling weight de- flectometer (FWD) and light weight deflectometer (LWD) are used as stiffness- or strength-based QA test methods. In Germany and some other European countries, a static strain modulus (Ev2) is more commonly used to verify bearing performance of paving layers. Ev2 is a modulus measured on second load stage of the static plate load test. In general, modulus determined from first load cycle is not reliable because there is too much re-arrangement of the gravel particles. However, a small number of load cycles may not be sufficiently dependable or reliable to be used as a design parameter. Experiments were conducted to study the influence of load cycles in bearing performance.

  • UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION

    UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION

    UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION SPONSORED and DISTRIBUTED by the 1998 ARIZONA (Includes revisions through 2010) FOREWORD Publication of these Uniform Standard Specifications and Details for Public Works Construction fulfills the goal of a group of agencies who joined forces in 1966 to produce such a set of documents. Subsequently, in the interest of promoting county-wide acceptance and use of these standards and details, the Maricopa Association of Governments accepted their sponsorship and the responsibility of keeping them current and viable. These specifications and details, representing the best professional thinking of representatives of several Public Works Departments, reviewed and refined by members of the construction industry, were written to fulfill the need for uniform rules governing public works construction performed for Maricopa County and the various cities and public agencies in the county. It further fulfills the need for adequate standards by the smaller communities and agencies who could not afford to promulgate such standards for themselves. A uniform set of specifications and details, updated and embracing the most modern materials and construction techniques will redound to the benefit of the public and the private contracting industry. Uniform specifications and details will eliminate conflicts and confusion, lower construction costs, and encourage more competitive bidding by private contractors. The Uniform Standard Specifications and Details for Public Works Construction will be revised periodically and reprinted to reflect advanced thinking and the changing technology of the construction industry. To this end a Specifications and Details Committee has been established as a permanent organization to continually study and recommend changes to the Specifications and Details.

  • Enhancement of Shaft Capacity of Cast-In- Place Piles Using a Hook System

    Enhancement of Shaft Capacity of Cast-In- Place Piles Using a Hook System

    Enhancement of Shaft Capacity of Cast-in- Place Piles using a Hook System by Ghazi Abou El Hosn A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of: Master of Applied Science in Civil Engineering Carleton University, Ottawa, Ontario ©2015 Ghazi Abou El Hosn * Abstract This research investigates an innovative approach to improve the shaft bearing capacity of cast- in-place pile foundations by utilizing passive inclusions (Hooks) that will be mobilized if movement occurs in pile system. An extensive experimental program was developed to study the shaft bearing capacity of cast-in-place piles with and without hook system in soft clay and sand. First phase of the experiment was developed to investigate the effect of passive inclusion on pile- soil interface shear strength behaviour, employing a modified direct shear test apparatus. The interface strength obtained for pile-soil specimens was found to significantly increase when passive inclusions were implemented. Apparent residual friction angle for concrete-sand interface increased from 22 to 29.5 when two hook elements were used at the pile-soil interface. The pile-clay apparent adhesion was also increased from 19 kPa to 34 kPa. A series of pile-load testing at field were performed on cast-in-place in soft clay to investigate the effect of passive inclusions on pile bearing capacity. The pile-load tests were conducted at Gloucester test site. Four model piles were cast with steel cages along with hooks (P1- no hook, P2-7 hooks, P3- 5 hooks and P4- 5 hooks) installed on the exterior side of the steel cages prior to filling the hole with concrete.
  • Engineering Geological Characterisation and Slope Stability

    Engineering Geological Characterisation and Slope Stability

    Engineering Geological Characterisation and Slope Stability Assessment of Whitehall Quarry, Waikato. A Thesis submitted in partial fulfilment of the requirements of the degree of Master of Science in Engineering Geology at the University of Canterbury by Daniel Rodney Strang UNIVERSITY OF CANTERBURY 2010 I Frontispiece Whitehall Quarry “Over 4,000 tonnes of aggregate goes into every 1 km of a two lane road” II Abstract Whitehall Quarry is located 4 km east of Karapiro, near Cambridge within the Waikato District. Current quarrying operations produce between 150,000 and 300,000 tonnes of aggregate for use in the surrounding region. This study is an investigation into the engineering geological model for the quarry and pit slope stability assessment. Pit slope stability is an integral aspect of quarrying and open-pit mining since slopes should be as steep as possible to minimise waste material which needs to be removed, yet shallow enough to minimise potential hazards to personnel and equipment below pit slopes. This study also assesses the stability of complex wedge located within the north western corner of the quarry. Initial estimates approximate a wedge mass volume of 500,000 m3; failure was triggered during the late 80‟s due a stripping programme at the head of the mass. Field and laboratory investigations were carried out to identify and quantify engineering geological parameters. Photogrammetric and conventional scanline analytical techniques identified two domains within the quarry divided by the Main Quarry Shear Zone (MQSZ). Discontinuity orientations are the key differences between the two domains. Bedding planes appear to have slightly different orientations and each domain has very different joint sets identified.
