Mechanistic-empirical modeling and design model development of geosynthetic reinforced flexible pavements : final report by Steven W Perkins ( Book )
2 editions published in 2001 in English and held by 43 WorldCat member libraries worldwide
Research over the past 20 years has demonstrated the benefit provided by geosynthetics when placed within or at the bottom of base aggregate layers in flexible pavement systems for the purpose of reinforcement. Previous experimental work involving the construction and loading of reinforced pavement test sections has demonstrated that values of benefit are strongly dependent on pavement design parameters such as thickness of the structural section and/or stiffness of the subgrade, and properties and type of geosynthetic used. A NCHRP Synthesis (Christopher et al., 2001), provides a survey of geosynthetic base reinforcement usage amongst all U.S. State transportation agencies. The survey found that the primary reasons for lack of usage were the absence of a suitable design method for defining reinforcement benefit and the corresponding inability to define cost benefit for reinforced pavement systems. This current project was undertaken to provide an analytically based method for the determination of reinforcement benefit. The method developed is expressed solely in terms of design equations used to calculate reinforcement benefit in terms of pavement structural thickness, subgrade strength and several properties related to the geosynthetic. The finite element model developed involves elastic plastic material models for the asphalt concrete, base aggregate and subgrade layers, and an anisotropic linear elastic model for the geosynthetic. Empirical distress models were developed to relate stress and strain response measures from the finite element model to pavement performance and ultimately reinforcement benefit. Three classes of finite element (FE) response models were developed. The first was for an unreinforced pavement cross section. The second was one in which reinforcement was modeled by preventing all lateral motion of the bottom of the base aggregate. The influence of geosynthetic properties was evaluated by creating a third class of FE model. In this model, the geosynthetic was explicitly accounted for by including a geosynthetic sheet, modeled with membrane elements, between the base aggregate and subgrade layer. This report provides a detailed description of the finite element response model, the material models used in the FE model, calibration of the material models and how these models relate to commonly used pavement layer material models, and the steps followed to develop the design model

Numerical modeling of geosynthetic reinforced flexible pavements by Steven W Perkins ( Book )
1 edition published in 2001 in English and held by 23 WorldCat member libraries worldwide
Experimental studies conducted over the course of the past 20 years have demonstrated both general and specific benefits of using geosynthetics as reinforcement materials in flexible pavements. Existing design solutions are largely empirically based and appear to be unable to account for many of the variables that influence the benefit derived from the reinforcement. Advanced numerical modeling techniques present an opportunity for providing insight into the mechanics of these systems and can assist with the formulation of simplified numerical methods that incorporate essential features needed to predict the behavior of these systems. Previous experimental work involving the construction of geosynthetic reinforced test sections has shown several difficulties and uncertainties associated with the definition of reinforcement benefit for a single cycle of load application. Even though many reinforcement mechanisms are apparent and often times striking during the application of the first load cycle, the distinction between reinforced test sections is not nearly so clear as that which is seen when examining long term performance, where long term performance is defined in terms of permanent surface deformation after many load cycles have been applied. This indicates the need for an advanced numerical model that is capable of describing the repeated load behavior of reinforced pavements. In particular, models for the various pavement layers are needed to allow for a description of the accumulation of permanent strain under repeated loads. To meet these needs, a finite element model of unreinforced and geosynthetic reinforced pavements was created. The material model for the asphalt concrete layer consisted of an elastic perfectly plastic model where material property direction dependency could be added. This model allowed for the asphalt concrete layer to deform with the underlying base aggregate and subgrade layers as repeated pavement loads were applied. A bounding surface plasticity model was used for the base aggregate and subgrade layers. The model is well suited for the prediction of accumulated permanent strains under repeated loading and is most suitable for fine grained materials. A material model containing components of elasticity, plasticity, creep and direction dependency was formulated for the geosynthetic and calibrated against a series of in air tension tests. A Coulomb friction model was used to describe shear interaction between the base aggregate and the geosynthetic. The model is essentially an elastic-perfectly plastic model, allowing for specification of the shear interface stiffness and ultimate strength. This model was calibrated from a series of pull out tests. Finite element models were created to match the conditions in pavement test sections reported by Perkins (1999a). Membrane elements were used for the geosynthetic and a contact interface was used between the geosynthetic and the base course aggregate. Models of unreinforced and reinforced pavement sections were created and compared to test section resuts

1 edition published in 2000 in English and held by 21 WorldCat member libraries worldwide
The true story of Brandon Johnson of Saratoga Wyoming who was involved in a accident while driving home from a party he attended at a friend's house. Brandon had not only been drinking but he also failed to buckle his seat belt before departing for home. He fell asleep while driving, veered off the road and rolled his car three times. Because Brandon was not wearing his seat belt, he was ejected from his car and is now a paraplegic

Determining bridge responses to overweight loads by Jeffrey L Schulz ( Book )
3 editions published in 1998 in English and held by 18 WorldCat member libraries worldwide
The Wyoming Department of Transportation (WYDOT) Office of Overweight Loads issues overload permits to motor carriers based on the results of conventional structural analysis of bridges along the anticipated permit route. This study was initiated to determine if current analytical methods accurately represent the actual live-load response of common bridge types, or if the results are over- or under-conservative in predicting maximum stresses. Field test procedures consisted of performing diagnostic load tests on each structure type as it was subjected to both a standard vehicle load and then an overload/permit vehicle. Finite element models were developed and an analysis performed with the same loads as those applied in the field. Comparisons between the measured strains and the analytical strains were made, and each model systematically modified until comparisons were in good agreement. The three bridge types used in the study are: Reinforced Concrete (R/C) Slab Bridge; R/C T-Beam Bridge; and Slab/Steel Girder Bridge

The Wyoming Department of Transportation geographic information system implementation project by Inc. (Boulder, Colorado) Environmental Systems Research Institute ( Book )
2 editions published in 2000 in English and held by 17 WorldCat member libraries worldwide
A geographic information system (GIS) was needed by the Wyoming Department of Transportation (WYDOT) to complement existing information management procedures and leverage the spatial component of its data. WYDOT contracted with Environmental Systems Research Institute, Inc. (ESRI) to provide planning and implementation services aimed at establishing GIS technology within the department. The methodology consisted of three distinct but tightly integrated planning stages: an initial plan that aligned GIS development with organizational goals and objectives, a conceptual plan that defined what the GIS was to accomplish, and a detailed plan that defined how the system would operate. The planning activities were followed by system deployment efforts that considered the acquisition, installation, construction, and integration of GIS hardware, software, data, applications, and organizational procedures
