Investigating The Impacts Of Sea Level Rise-Induced High Groundwater Table On Florida Flexible Pavement Structural Performance, Mehmet Goksel Gocmez

FIU Electronic Theses and Dissertations

This thesis evaluates the impacts of sea-level rise-induced high groundwater table on the structural performance of typical Florida interstate, arterial, and local flexible pavements. Pavement longevity was determined under rising groundwater table level conditions using two analytical methods; the mechanistic-empirical (ME) analysis software and the current Florida empirical analysis practice. Moreover, ABAQUS and KENLAYER software were utilized to analyze the impacts of stress-dependent material nonlinearity on pavement structural performance.

Analysis results estimated that the pavement service life in Florida was reduced by as much as 77 percent with the effects of rising groundwater levels. The empirical method predicted higher rates …

Effect Of Polypropylene Fiber Reinforcement On The Consolidation, Swell And Shrinkage Behavior Of Lime Blended Expansive Soil, Arif Ali Baig Moghal, Bhaskar C.S. Chittoori, B. Munwar Basha

Civil Engineering Faculty Publications and Presentations

In this article, synthetic fibers in the presence of lime stabilization are proposed as an alternative to overcome the issues related to shrink-swell distress in expansive soils. Two types of synthetic fibers, Fiber Cast® (FC) and Fiber Mesh® (FM), were studied by conducting one dimensional fixed ring Oedometer swell-consolidation and bar linear shrinkage tests. Three dosages (0.2, 0.4 and 0.6% percent by weight of soil) and two lengths of the fibers (6 and 12 mm) were evaluated with and without lime treatments. The results indicated that FC fibers had better swell restricting performance in the absence of lime treatment, while …

Evaluation Of Durability And Homogeneity Of Rejuvenated Asphalt Binders, Mojtaba Mohammadafzali

FIU Electronic Theses and Dissertations

Despite the widespread recycling of Reclaimed Asphalt Pavement (RAP), a large portion of it is still wasted. One of the main reasons is the concern with the performance of high RAP mixtures. Asphalt binder aging and subsequent rejuvenation is one source of uncertainty. Rejuvenators are frequently added to high RAP mixes to enhance the properties of the binder. This enhancement is often perceived as simply lowering the viscosity. Two important parameters that are not adequately addressed by existing methods are durability and homogeneity of the recycled binder. This research investigated these two concerns and provided quantitative indicators to measure them. …

Modeling Long-Term Deformations Of Unbound Pavement Materials Using The Miniaturized Pressuremeter Creep Data, A. M. Shaban, P. J. Consentino

Mechanical and Civil Engineering Faculty Publications

This research was undertaken to study the predictive capability of the pressuremeter test for characterizing in situ creep behavior of unbound pavement layers. Although the creep potential of granular pavement materials is less pronounced than fine-grained soils, consideration of actual creep deformations in the pavement evaluation process will improve long-term pavement performance. In this investigation, the long-term deformations determined from laboratory one-dimensional creep tests were compared with those investigated by field pressuremeter tests. The pressuremeter test consisted of inflating a cylindrical probe incrementally up to a given stress level, and then maintaining the pressure constant for a 5-min single stage. …

Effect Of Fiber Reinforcement On Cbr Behavior Of Lime Blended Expansive Soils: Reliability Approach, Arif Ali Baig Moghal, B. Munwar Basha, Bhaskar Chittoori, Mosleh Ali Al-Shamrani

Civil Engineering Faculty Publications and Presentations

Use of synthetic fibers as reinforcement to stabilize expansive soils is gaining momentum. As a contribution towards this growing field of research two different types of synthetic fibers, Fiber Mesh® and Fiber Cast®, were evaluated as a stabilization alternative for expansive soils in the presence of lime. California Bearing Ratio (CBR) is chosen as a performance indicator as it is a good pointer towards pavement effectiveness. Variables such as length and amount of the fibers as well as curing period were studied. Both deterministic and probabilistic (or reliability) analysis is presented in this paper. While the deterministic analysis helps in …

Gis Based Pavement Maintenance: A Systematic Approach, Robert J. Kmetz

Purdue Polytechnic Directed Projects

Abstract

According to 2008 Federal Highway Administration (FHWA) statistics, there are 2,734,102 miles of paved public roads in the United Sates, with an additional 1,324,245 miles of unpaved public roads. Road conditions deteriorate with time as the result of weather effects, deicing salts, and vehicle loads. The most common pavement distress includes cracking, rutting, and potholes. These pavement defects must be repaired to restore the pavement to a satisfactory service level for road users. According to the FHWA, in 2006 approximately $54.2 billion dollars was spent on maintenance and expansion, just on U.S. highways alone.

Routine maintenance is a cost …

Automated Pavement Condition Data Collection Quality Control, Quality Assurance, And Reliability, Ghim Ping (Raymond) Ong, Samy Noureldin, Kumares C. Sinha

JTRP Technical Reports

In recent years, state highway agencies have come to understand the need for high quality pavement condition data at both the project and network levels. At the same time, agencies also realize that they have become too dependent on contractors to ensure the quality of the delivered data without any means to independently assure the quality of these delivered data. This research study therefore aims to investigate the inherent variability of the automated data collection processes and proposes guidelines for an automated data collection quality management program in Indiana. In particular, pavement roughness data (in terms of IRI) and pavement …

A Methodological Framework For Modeling Pavement Maintenance Costs For Projects With Performance-Based Contracts, Kamalesh Panthi

FIU Electronic Theses and Dissertations

Performance-based maintenance contracts differ significantly from material and method-based contracts that have been traditionally used to maintain roads. Road agencies around the world have moved towards a performance-based contract approach because it offers several advantages like cost saving, better budgeting certainty, better customer satisfaction with better road services and conditions. Payments for the maintenance of road are explicitly linked to the contractor successfully meeting certain clearly defined minimum performance indicators in these contracts. Quantitative evaluation of the cost of performance-based contracts has several difficulties due to the complexity of the pavement deterioration process. Based on a probabilistic analysis of failures …

Effects Of Aggregate Angularity On Mix Design Characteristics And Pavement Performance, Yong-Rak Kim, Leonardo T. Souza

Mid-America Transportation Center: Final Reports and Technical Briefs

This research targeted two primary purposes: to estimate current aggregate angularity test methods and to evaluate current aggregate angularity requirements in the Nebraska asphalt mixture/pavement specification. To meet the first research objective, various aggregate angularity tests were estimated with the same sets of aggregates and were compared by investigating their characteristics on testing repeatability, cost, testing time, workability, and sensitivity of test results. For the second objective, the effect of aggregate angularity on mixture performance was investigated by conducting laboratory performance tests (the uniaxial static creep test and the indirect tensile fracture energy test) of five mixes designed with different …

Performance Related Specifications (Prs) For Concrete Pavements In Indiana, Volume 2: Technical Report, Cole Graveen, Eric Max Falker, Micah Beaver, Narayanan Neithalath, W. Jason Weiss, J. Olek, Tommy Edward Nantung, Victor Lee Gallivan

Saw-Cutting Guidelines For Concrete Pavements: Examining The Requirements For Time And Depth Of Saw-Cutting, Kambiz Raoufi, Tony Their, W. Jason Weiss, Jan Olek, Tommy E. Nantung

JTRP Technical Reports

Joints are placed in Portland cement concrete pavements (PCCP) to control random cracking. These joints provide a weakened plane that enables a crack to form in a controlled manner, relieving residual stresses that develop when thermal, hygral, or hydration movements are resisted by sub grade and adjoining pavement. While the concept of creating a weakened plane through saw-cutting is straightforward, determining the time and depth of the saw-cut has proven to be complicated. The goal of this project was to reduce the risk for joint raveling and random cracking. Specifically, this project has focused on: developing a procedure for determining …

The Nebraska Department of Roads (NDOR) conducts annual examinations of the Nebraska’s interstate and federal high-way pavements. During these examinations, numerous indicators of pavement quality are measured directly or are com-piled from parameters recorded by a vehicle passing over the pavement section. Parameters are documented and analyzed for each one-tenth mile segment. A number of pavement sections where innovative features have been incorporated were selected by the NDOR for comparison to nearby conventional pavement sections. This study used data recorded by the NDOR as well as field observations to develop a comparison between two pavement sections, one with innovative fea-tures …

Investigation Of Asphalt Pavement Analyzer Testing Program In Nebraska, Minki Hong, Yong-Rak Kim

Mid-America Transportation Center: Final Reports and Technical Briefs

The asphalt pavement analyzer (APA) has been widely used to evaluate hot-mix asphalt (HMA) rutting potential in mix design and quality control – quality assurance (QC-QA) applications, because the APA testing and its data analyses are relatively simple, rapid, and easy. However, as demonstrated in many studies and also experienced by the state of Nebraska, the APA testing is in question due to its high testing variability and a lack of sufficient correlation with actual filed performance. The primary objective of this research was to find critical materials and/or mixture design factors affecting APA test results so as to eventually …

Hot In Place Asphalt Recycling (Hipar), Purdue Ect Team

ECT Fact Sheets

With limited funds destined to highway maintenance, the need to repair and maintain highways at the lowest cost possible has created a need for cost-effective ways to rehabilitate existing pavements in preference of reconstruction. Hot-In-Place-Asphalt-Recycling is defined as a process of correcting asphalt pavement surface distress by softening the existing surface with heat, mechanically removing the pavement surface, mixing with recycling agent, possibly adding virgin asphalt and/or aggregate and replace it on the pavement without removing the recycled material from the original pavement site.

Interaction Between Micro-Cracking, Cracking, And Reduced Durability Of Concrete: Developing Methods For Considering Cumulative Damage In Life-Cycle Modeling, Zhifu Yang, W. Jason Weiss, J. Olek

JTRP Technical Reports

It is becoming increasingly popular to utilize numerical simulation models to predict the long-term performance of concrete pavements and structures. The majority of these models have been developed using laboratory test data that considers concrete in an uncracked state. While uncracked concrete exists as the best case scenario, frequent cracking occurs in real structures that could have a profound impact on life cycle performance. Cracks from several sources may accumulate and interact thereby accelerating the deterioration of concrete. For example, the distributed cracking caused by freeze/thaw damage can substantially increases the rate of water absorption and reduces the load carrying …

Initial Study For Cost-Effectiveness Of Joint/Crack Sealing, Chuanxin Fang, Khaled A. Galal, David R. Ward, John E. Haddock

JTRP Technical Reports

The sealing and resealing of joints and cracks in PCC, HMA, and composite pavements is assumed to be an important component of pavement maintenance. Recently this practice has been challenged by research indicating that sealing may not be cost-effective. The Indiana Department of Transportation currently spends approximately four million dollars annually to perform joint/crack sealing. The primary objective of the research presented in this report is to investigate the costeffectiveness of joint/crack sealing in relation to pavement performance. The results of a mail survey showed that most states, including Indiana, do not have quantitative justification for sealing policies, nor do …

Ultra-thin Whitetopping (UTW) involves placing a very thin concrete overlay 50 mm to 100 mm thick (2”-4”) on the milled surface of a distressed asphalt pavement. To investigate the performance of UTW placed over a flexible pavement subjected to slow and heavy moving wheel loads, whitetopping mixes were placed over a milled pavement surface in the Accelerated Pavement Testing (APT) facility of the Indiana Department of Transportation (INDOT) Research Division in West Lafayette Indiana in the fall of 1999. The UTW installation experiment consisted of four test ‘lanes’ of two different thicknesses; each utilizing plain and fiber reinforced concrete. The …

Seasonal And Spatial Variation Of Subgrade Response, Mustaque Hossain, Stefan Romanoschi, Andrew J. Gisi

Civil Engineering Faculty Publications

Temperature, subgrade moisture content, and Falling Weight Defleetometer (FWD)-deflection data were collected monthly on four asphalt pavement test sections in Kansas for a year. The subgrade moduli were baekealeulated using the elastic layer theory. It was found that for almost all sites, the monthly variation in subgrade moisture content was not very significant over the seasons. The patterns of subgrade response, in terms of subgrade moduli versus time, simulated sine-shaped forms signifying a possible temperature effect. Higher variabilities across the site were associated with the extreme temperature conditions, usually very low or high average pavement temperatures. In all cases, the …

Development Of A 3-D Finite Element Program For Pavement Analysis, Volume I: Introduction And Appendix 1, Tatsaba Nilaward, Chiang Shih, Thomas D. White, E. C. Ting

JTRP Technical Reports

A three dimensional finite element program is developed for the analysis of pavement systems. An explicit approach of the finite element analysis is adopted. This approach results in a vector formulation of the equation of motion. Large displacement is considered through the use of a co-rotational approach which considers small deformations and large rotations of the elements. For the convenience of application a two dimensional finite element program is also developed. An eight-node ¶metric solid element is used for the three dimensional analysis, and a four-node element for the two dimensional analysis. Loading conditions are verified for static ramp and …
