An Accelerated Testing System To Determine Percent Crushed Aggregate Requirements In Bituminous Mixtures, Thomas D. White, J. M. Abers, John E. Haddock

JTRP Technical Reports

With increase in axle loads, tire pressures and volume of truck traffic there has been an increase in the rate of which bituminous pavements are exhibiting rutting. Because resistance to rutting can be increased by the addition of crushed aggregate, a need exists for a method of determining what amount of crushed material is required and the characteristics of that crushed material to optimize performance and economy.

The Accelerated Testing Facility will be located at the INDOT Research Division Facilities in West Lafayette, Indiana. A pit within the Test Facility will allow prototype scale pavement sections to be installed. An …

The Effects Of The All-Red Clearance Interval On Intersection Accident Rates In Indiana, Brian Alan Roper, Jon D. Fricker, Kumares C. Sinha, Robert E. Montgomery

JTRP Technical Reports

The research reported is an evaluation of all-red clearance intervals as the second phase of a project involving traffic signal operation. The first phase of the project dealt with leading versus lagging left turn signal phasing. The study analyzed both the short-term and long-term effects of all-red interval on accident rates in Indiana using accident records for the years 1981 to 1987. The results contradict those of previous studies. Statistical tests indicated that all-red clearance intervals did not cause a reduction in accident rates at the intersections studied in Indiana.

Residual Circulation In Shallow Estuaries 2. Weakly Stratified And Partially Mixed, Narrow Estuaries, David A. Jay, J. Dungan Smith

Civil and Environmental Engineering Faculty Publications and Presentations

Long-wave theory is used herein to analyze circulation in weakly stratified and partially mixed estuaries. Unlike the highly stratified systems considered in part 1, the flows considered here have only a minimal tidal-frequency internal wave component. These estuaries may therefore be modeled as the sum of weakly interacting barotropic and baroclinic modes. The dominant factors driving the residual flow are finite amplitude barotropic effects in weakly stratified estuaries and a combination of barotropic effects and steady horizontal density gradient forcing in partially mixed estuaries. The dominant vertical exchange mechanism in the weakly stratified case is bottom boundary-induced turbulence, and that …

Allocation Of Highway Costs And Revenues, Jerry G. Pigman, John A. Deacon

Residual Circulation In Shallow Estuaries 1. Highly Stratified, Narrow Estuaries, David A. Jay, J. Dungan Smith

Civil and Environmental Engineering Faculty Publications and Presentations

Long-wave theory and simple turbulence closures have been used to show that three distinct types of circulation (highly stratified, weakly stratified, and partially mixed) arise in narrow, shallow estuaries from the finite amplitude of the tide and the interaction of stratification with vertical mixing. Each type has a different dominant process causing the vertical exchange of salt and fresh water on the flood, and each gives rise to a characteristic residual circulation. The tidal circulation in highly stratified shallow estuaries, described herein, is the result of a finite amplitude internal motion driven by the barotropic tide; shear instabilities at the …

Exeis, Expert Screening And Optimal Extraction/Injection Pumping Systems For Short-Term Plume Immobilization, R. L. Ward, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

This report presents the EXEIS family of micro-computer based programs for achieving short-term contaminant plume containment. EXEIS is applicable if contaminated water cannot be extracted and water cannot be imported to or exported from the site. There are two main purposes and types of users. For persons relatively unfamiliar with groundwater remedial actions, an expert screening system gives guidance concerning whether extraction/injection (Eli) pumping, slurry wall or sheet piling are most appropriate. For personal more experienced in remedial actions, management models compute optimal E/I strategies for short-term containment. Via deterministic and stochastic multiobjective optimization models, uncertainty in both planning horizon …

Optimal Conjunctive Use Of Ground And Surface Waters, Richard C. Peralta, A. Gharbi, L. S. Willardson, A. W. Peralta

Civil and Environmental Engineering Faculty Publications

Conjunctive water management involves coordinating the use of groundwater and surface water in time and in space. The water sources might or might not be in hydraulic connection with each other. In this chapter, conjunctive water use involves the combined use of surface and groundwater to supply crop water needs.

Two simplified examples of conjunctive use follow. Farmer Allen uses river water to irrigate his crops. In dry years, with below average stream flow, his surface water supply is severely limited by late summer. To augment this surface water supply, he pumps groundwater. In wet years, when the surface water …

Conjunctive Water Use/Sustained Groundwater Yield Planning: Case History, A. R. Yar, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

A methodology for computing perennial ground-water yield and conjunctive water use strategies is presented, using the Arkansas Grand Prairie as a case study. This includes development and use of an optimization model for computing sustainable ground-water pumping strategies and a post-processor for allocating ground-water and surface water supplies in time and space. The optimization model utilizes embedded finite difference flow equations as constraints and bounds on pumping, recharge and potentiometric head. Computed conjunctive use strategies will maintain, as much as possible, the existing stressed potentiometric surface. They will also assure at least 6 meters of saturated thickness in all locations …

Groundwater Seepage Into The Indian River Lagoon At Port St Lucie, Ashok Pandit, Clovis Clovis El-Khazen

Mechanical and Civil Engineering Faculty Publications

A finite element program, GROSEEP, was developed to estimate the groundwater seepage from the surficial aquifer into Indian River lagoon along a selected cross-section in Port St. Lucie, Florida. The model is a general purpose model and can be used at other cross-sections. Model results using a single layer indicate that groundwater seepage could be an important freshwater source into the lagoon. Sensitivity analysis using a three-layer model predicted that among other parameters the presence of windows in the clay layers could significantly affect seepage rates into the lagoon.

Cost Comparison Of Timber, Steel, And Prestressed Concrete Bridges, Richard A. Behr, E. J. Cundy, C. H. Goodspeed

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study was undertaken to investigate the economics of timber bridge superstructures versus traditional steel/concrete and prestressed concrete alternatives in the short-span range of 20 to 60 ft (6.1-18.3 m). Only superstructure costs were considered because substructure and abutment costs are highly site-specific. A lack of definitive data regarding service lives and maintenance costs precluded a life-cycle cost study; thus, only initial costs were compared. Representative superstructure designs were obtained for timber, steel/concrete, and prestressed concrete bridges at 20-, 40-, and 60-ft spans. Five to six northern New England general contractors performed cost estimates on these designs. Also, nine timber …

Failure Strengths Of Laminated Glass, Joseph E. Minor, Patrick L. Reznik

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Laminated glass used in architectural glazing comprises two layers of glass connected by a thin interlayer of polyvinyl butyral. Previously reported nondestructive experimental stress analyses offer evidence that laminated glass behaves like monolithic glass of the same nominal thickness except when temperatures are high. This evidence has been augmented to include failure behavior by destructive tests of a large number of laminated-glass specimens. Test results reveal that failure strengths of annealed laminated-glass specimens are equal to failure strengths of annealed monolithic glass specimens of the same nominal thickness at room temperature and decrease to about 75% of monolithic-glass strength at …

Seal Forces In Structural Glazing Systems, C. V.Girija Vallabhan, Gee D. Chou, Joseph E. Minor

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Silicone sealants are used as structural connections between the two glass plates in an insulating glass (IG) unit and between the IG unit and the supporting mullion. These connections become an integral part of the entire glazing system, worthy of attention by structural design engineers. Since the behavior of IG units subjected to lateral pressures, such as wind, is highly nonlinear, von Karman plate equations are employed in the mathematical model developed here. Also, since the two thin glass plates are separated by a sealed air space, a complex interaction occurs between the trapped air space and the glass plates. …
