  • Reinforced Earth: Principles and Applications in Engineering Construction
    International Journal of Advanced Academic Research | Sciences, Technology & Engineering | ISSN: 2488-9849 Vol. 2, Issue 6 (June 2016) REINFORCED EARTH: PRINCIPLES AND APPLICATIONS IN ENGINEERING CONSTRUCTION Okechukwu, S.I; Okeke, O. C; Akaolisa, C. C. Z; Jack, L. And Akinola, A. O. Department of Geology, Federal University of Technology, Owerri, Imo State, Nigeria Abstract Reinforced earth is a material formed by combining earth and reinforcement material. The reinforced soil is obtained by placing extensible or inextensible materials such as metallic strips or polymeric reinforcement within the soil to obtain the requisite properties. The reinforcement enables the soil mass to resist tension in a way which the earth alone could not. The source of this resistance to tension is the internal friction of soil, because the stresses that are created within the mass are transferred from soil to the reinforcement strips by friction. Reinforcement of soil is practiced to improve the mechanical properties of the soil being reinforced by the inclusion of structural elements. The reinforcement improves the earth by increasing the bearing capacity of the soil. It also reduces the liquefaction behavior of the soil. Reinforced earth is not complex to achieve. The components of reinforced earth are soil, skin and reinforcing material. The reinforcing material may include steel, concrete, glass, planks etc. Reinforced earth has so many applications in construction work. Some of the applications include its use in stabilization of soil, construction of retaining walls, bridge abutments for highways, industrial and mining structures. Keywords: Reinforcement, Reinforced earth. 1.0 Introduction An internally stabilized system such as reinforced earth involves reinforcements installed within and extending beyond the potential failure mass.

  • Scheduling SS-1
    Scheduling SS-1 BMP Objectives ● Soil Stabilization ● Sediment Control ● Tracking Control ● Wind Erosion Control ● Non-Storm Water Management ● Materials and Waste Management Definition and Purpose This BMP involves developing a schedule for every project that includes sequencing of construction activities with the implementation of construction site BMPs such as temporary soil stabilization (erosion control) and temporary sediment controls measures. The purpose is to reduce the amount and duration of soil exposed to erosion by wind, rain, runoff, and vehicle tracking. Appropriate Applications Any construction project where soils will be disturbed will benefit from a BMP sequencing schedule that is generated in conjunction with the construction-sequencing schedule. BMP sequencing can help minimize land disturbance during construction. Limitations The BMP sequencing schedule must be agreed upon between MDT and the construction contractor. BMP scheduling is only effective if the scheduled is followed closely and modified as required throughout the construction project. Design Guidelines and Considerations n Plan the project and develop an implementation schedule of construction site BMPs. The schedule is designed to clearly show how the BMPs relate to soil-disturbing and re- stabilization activities. The construction schedule is typically incorporated into the SWPPP. n A BMP schedule includes details on the implementation and deployment of: - temporary soil stabilization BMPs, - temporary sediment control BMPs, 10 - tracking control BMPs, - wind erosion control BMPs, - non-storm water BMPs, and - waste management and materials pollution control BMPs. n Also included in the BMP schedule are dates for significant long-term operations or activities that may have planned non-storm water discharges such as dewatering, saw cutting, grinding, drilling, boring, crushing, blasting, painting, hydro-demolition, mortar mixing, bridge cleaning, etc.

  • Use of Class C Fly Ash for Stabilization of Soft Subgrade
    SFUND RECORDS CTR 2065253 Fifth International Congress on Advances in Civil Engineering. 25-27 September 2002 Istanbul Technical University. Istanbul, Turkey Use of Class C Fly Ash For Stabilization of Soft Subgrade §ENOL, A., PhD Istanbul Technical University, Civil Engineering Faculty Geotechnical Engineering Department Istanbul, TURKEY BIN-SHAFIQUE, Md. S., PhD Candidate, EDiL, T.B., Prof BENSON, C.H., Prof Department of Civil and Environmental Engineering University of Wisconsin-Madison, USA Abstract i1 ii This paper represents the results of a study aimed at using self-cementing Class C fly ash for the stabilization of soft subgrade of a city street in Cross Plains, [Wisconsin, U.S.A. Both strength and modulus-based approaches were applied to [estimate the optimum mix design and to determine the thickness of the stabilized layer.J Stabilized soil samples were prepared mixing fly ash at three different contents at varying water contents. The samples were subjected to unconfined compression test after seven days of curing to develop 'water content-strength relationship. To evaluate the' impact of compaction delay that commonly occurs in field construction, one set of the samples was compacted just after mixing with water, while the other set after two hours. CBR and resilient modulus tests were conducted and used to determine the thickness of the stabilized layer in pavement design. Some field tests were also performed after the construction, which showed that the fly ash stabilization improved the 'engineering properties significantly. !' Introduction Fly Ash is one of the most plentiful and versatile of the industrial by-products (Collins and Ciesielski 1992).

  • Enzyme Based Soil Stabilization for Unpaved Road Construction
    MATEC Web of Conferences 138, 01002 (2017) DOI: 10.1051/matecconf/201713801002 EACEF 2017 Enzyme based soil stabilization for unpaved road construction Rintu Renjith1 , Dilan Robert1, Andrew Fuller2, Sujeeva Setunge1, Brian O’Donnell3, and Robert Nucifora2 1Civil Engineering, RMIT University, Australia 2Infrastructure Services, Downer Group Ltd, Australia 3Center for Pavement Excellence Asia Pacific Abstract. Enzymes as soil stabilizers have been successfully used in road construction in several countries for the past 30 years. However, research has shown that the successful application of these enzymes is case specific, emphasizing that enzyme performance is dependent on subgrade soil type, condition and the type of enzyme used as the stabilizer. A universal standard or a tool for road engineers to assess the performance of stabilized unbound pavements using well-established enzymes is not available to date. The research aims to produce a validated assessment tool which can be used to predict strength enhancement within a generalized statistical framework. The objective of the present study is to identify new materials for developing the assessment tool which supports enzyme based stabilization, as well as to identify the correct construction sequence for such new materials. A series of characterization tests were conducted on several soil types obtained from proposed construction sites. Having identified the suitable soil type to mix with the enzyme, a trial road construction has been performed to investigate the efficiency of the enzyme stabilization along with the correct construction sequence. The enzyme stabilization has showed significant improvement of the road performance as was evidenced from the test results which were based on site soil obtained before and after stabilization.

  • Gravel Roads Construction and Maintenance Guide Table of Contents Subject Page
    Errata ­ Replaces page 137 Reconstruction Using a Detour When the reconstruction and resulting berm are significant, the work space takes all or most of the road surface, leaving no room for traffic to negotiate past the work activities. An agency may need to reconstruct the unpaved roadway by correcting the drainage and/or adding surface materials. With this type of work, additional equipment may be used and a large amount of material may create a large berm (12 inches or more across). This will present significant hazards for the traveling public. To improve safety for mo­ torists and workers, a detour may be the best TTC. Not all road users will be familiar with the local road system and some may be confused by the road closure, so signing should be used to assist users negotiating the detour. Reconstruction work space. (Source: Greg Vavra, SDLTAP). Notes: 1. Not all local agencies use route makers for their system. MUTCD Section 6F.59 states “A Street Name sign should be placed above, or the street name should be incorporated into, a DETOUR (M4­9) sign to indicate the name of the street being detoured.” 2. With an increase in traffic at the intersections where the detour begins and ends, a review of the usage of the STOP and YIELD signs should be completed. 3. Flashing warning lights and/or flags may be used to call attention to advance warning signs. 4. Flashing warning lights may be used on the Type 3 Barricades, which should be installed at the point where the road is closed.

    Literature Search: NS 609: Evaluation of Gravel Stabilizer Used on Gravel Roads and Gravel Shoulders Date: July 2, 2021 Prepared for: Marcus Bekele Prepared by: Sheila Hatchell | contact: [email protected] Resources searched: Compiled results are from the following databases: TRID, RIP, Transport, ASCE, Google Scholar, Internet, MnDOT Library Catalog. Results are categorized as “Most Relevant” or “Other.” Summary: Links are provided for full-text, if applicable, or to the full record citation. If the resource was only available as a PDF download, I saved and attached the PDF for you. I completed my searches using the following keywords: Gravel stabilizers, Gravel roads, Low volume roads, Soil stabilizers, BaseOne, EN1, ClayCrete, EMC squared, Dustex. Also, from what I have been able to determine, I think this title is misleading and should instead be Evaluation of Soil Stabilizers Used on Gravel Roads and Gravel Shoulders. Topic Description: Many Minnesota counties have been using gravel stabilizers on their gravel roads over the last decade, and have reported decreases in the amount of gravel, grading, dust suppressants, and fossil fuel required to maintain their gravel roads. This study would quantify those saving as well as determine whether savings are possible for their use on gravel shoulders. Propose to study at least two stabilizers used on both natural and carbonate gravel roads and shoulders. Some counties have realized savings in gravel road maintenance costs of +50%. The greatest savings were in the required grading hours, which decreased 75%. This translates into savings in fossil fuel and subsequently green house gases. These savings should be quantified by a formal study so that they can be better shared with other users.

  • Geocells in 2005 – Our flagship Product – Following a Two- Year Testing in Our Company Labs, Became the Boosting Success
    Who we are? On the market since 1993 Geo Globe Polska (formerly Kruk i Fischer) was established in 1993 as a joint venture enterprise with a German partner Dr K.G. Fischer. In response to the vast market potential we are still developing and enlarging the range of our services. Our leading technology then was vacuum thermoforming of plastics such as: ABS, PE, PS, PP, PMMA, which involves heating plastic to a point of plasticity before it is injected by ram pressure into the closed mold cavity. After several years – as a result of reorganization – Kruk i Fischer became a family-owned business with all the capital being owned by the members of the Kruk family. A step forward in the history of Kruk i Fischer was the purchasing of MIPLAST Sp. z o.o. – former Nitron S.A. Scientific Research Centre with its registered seat in Mikołów in the year of 2003. In the years to follow the Enterprise has been earning reputation of a leader on the plastic industry market. Then the market launch of GEOMAXX® geocells in 2005 – our flagship product – following a two- year testing in our company labs, became the boosting success. In 2008 we received an EU grant support from the European Regional Development Fund following the Sectoral Operational Programme Improvement of the Competitiveness of Enterprises, years 2004–2006 for our project called Innovative Technology of Geocells of Various Resistances and Temperature Resistance. Another grant from the EU funds from the European Fundation of Regional On October 1st, 2008 the enterprise was transformed from a limited Development the Regional Operational Programme of the Silesia liability company into a limited Voivodeship (ROP SV) for years 2007-2013 for the project called: joint-stock partnership, "Innovative technology for production of sheets and film production changing alsoits business name based on obtained granulate" allowed us to extend our possibilities.

  • Some Factors Influencing Shear Strength and Compressibility of Compacted Soils L
    Some Factors Influencing Shear Strength and Compressibility of Compacted Soils L. J. LANGFELDER and V. R. NIVARGIKAR, Department of Civil Engineering, North Carolina State University, Raleigh •THE GREAT majority of state highway departments are presently using dry density as the principal criterion for judging the quality of compacted earthwork. This criterion implies that increased dry density produces improved engineering properties in the material. Although the use of dry density for field control can be easily accomplished, particularly with the increasing use of nuclear devices, its value as a usable criterion is only valid insofar as the dry density does, in fact, indicate the engineering properties of the material. The two most important and generally applicable properties that con­ cern the highway designer are the shear strength and the compressibility character­ istics of the compacted materials. However, for certain soils and in many geographic areas the shrinkage and swell potential and the frost susceptibility may be of greater concern to the highway designer than the shear strength and compressibility character­ istics. The major purpose of this paper is to present a review of the presently available (1966) literature concerning some of the factors, in addition to the dry density, that affect the engineering behavior of compacled soils. Because of space limitations only shear strength and compressibility will be dealt with; for clarity of presentation, cohesionless and cohesive materials will be discussed separately. SHEAR STRENGTH OF COHESIONLESS MATERIAL Maj or Factors The shear strength of cohesionless materials is essentially controlled by five factors: (a) mineralogical composition, (b) size and gradation of the individual particles, (c) shape of the individual particles, (d) void ratio or dry density, and (e) confining pressure.
