Endogenous International Technology Spillovers And Biased Technical Change In The Gtap Model, Hans Van Meijl, Frank Van Tongeren

GTAP Technical Papers Archive

This paper discusses the implementation of embodied international technology spillovers in the GTAP model.

We specify a transmission mechanism for technical knowledge that assumes that knowledge is embodied in traded commodities. The usability of knowledge in the receiving country is dependent on the local absorption capacity (e.g., human capital, knowledge infrastructure) and on structural differences (e.g., factor endowments, climate) between countries.

This concept is illustrated first by modeling spillovers embodied in final products and Hicks-neutral technical change.

The bulk of the paper deals with factor-biased technical change in agriculture, and its international transmission through traded intermediate inputs.

We demonstrate how …

Contributions Of Pg Graded Asphalt To Low Temperature Cracking Resistance Of Pavement, Ssu-Wei Loh, J. Olek

JTRP Technical Reports

The purpose of this research was to study and evaluate the role that asphalt binders play in the resistance of asphalt pavements to low temperature cracking. As part of the Strategic Highway Research Program (SHRP) new specifications for asphalt binders were developed that are based on the performance of the material. The asphalt binder graded and specified according to these new performance-based specifications is called PG binder. These new specifications are commonly referred to as Superpave (Superior Performing Asphalt Pavement) binder specifications. A section of Interstate 64 in southern Indiana was experiencing severe low temperature cracking before it was reconstructed …

Flexible Pavement Drainage Monitoring, Performance, And Stability, Aiwen Feng, Jianfeng Hua, Thomas D. White

JTRP Technical Reports

The current study is a continuation of the study FHWA/IN/JTRP project HPR-2078, “Locating the Drainage Layer for Flexible Pavements”. In this previous study, three test sections were constructed in a new pavement on a by-pass around Fort Wayne, Indiana. These test sections were instrumental to record temperatures, moisture, frost penetration, rainfall and subdrainage system overflow. Collected data and Finite Element Method (FEM) analysis indicate the subdrainage systems are performing satisfactorily. However, concern developed over the stability and rutting characteristics of the open-graded drainage layers. As a continuation study, longer term environmental and subdrainage performance data was collected. Additional data was …

Landslide Remediation Using Unconventional Methods, Richard J. Deschamps, Cary B. Lange

JTRP Technical Reports

Landslides are very common within the residual soils and sedimentary rock of Southern Indiana. A substantial amount of the Indiana State budget is spent on road repair and maintenance from damage caused by landslide. The landslide remedial technique frequently applied by the Indiana Department of Transportation (INDOT) is the excavation and backfill method, which in most instances is successful. However, in many cases more liberal landslide treatments may be applied that would arrest movement, provide a sufficient safety factor, and at a lower cost. The objective of this study is to propose economically feasible landslide remedial methods that may be …

Methods Of Corrosion Protection And Durability Of Concrete Bridge Decks Reinforced With Epoxy-Coated Bars - Phase I, Lisa Michele Samples, J. A. Ramirez

JTRP Technical Reports

In this study, the results of an extensive field and laboratory investigation conducted to evaluate the corrosion performance of epoxy-coated reinforcement are reported. One hundred and twenty three concrete bridge decks containing epoxy-coated reinforcement, uncoated reinforcement, and various other corrosion protection systems were included in a field investigation. An initial visual inspection of these bridge decks showed that 44% had signs of distress from corrosion of the reinforcement. Six decks, representing 5% of the total sample, were selected for a second more detailed survey. Three of the six decks had epoxy-coated reinforcement. This number represents 11% of the total sample …

Embankment Widening Design Guidelines And Construction Procedures, Richard J. Deschamps, Christopher S. Hynes, Philippe L. Bourdeau

JTRP Technical Reports

In recent years failures have occurred in Indiana highway embankments where the embankments were widened and steepened in order to facilitate construction of longer, safer acceleration and deceleration lanes and to increase the traffic capacity and efficiency of existing thoroughfares. The objectives of this study were to investigate the cause of failure and to make recommendations for modifying the existing INDOT Standard Specifications and construction guidelines in an attempt to avoid similar failures in the future. A literature review and survey of state and federal transportation agencies was performed to collect current, available design guidelines and construction procedures for sideslope …

Effects Of Salt And Its Trace Minerals On Aggregate In Bituminous Pavements, Terry R. West, H. J. Park, S. E. Grover

JTRP Technical Reports

Research on the effects of deicing salts and their trace minerals on bituminous highway wearing courses was prompted by early pavement deterioration of federal and state highways in Indiana. Several bituminous surface courses containing slag, slag-dolomite, or dolomite aggregates showed deterioration soon after deicing salts were first applied. Initially, a detailed literature review (Appendix A of report) was conducted. Data on eighteen dolomite sources from a previous study (Bruner, Choi and West, 1995) plus ten additional dolomite sources formed the basis for the brine freeze thaw testing program. Mercury intrusion porosimetry testing conducted on multiple specimens showed that rock texture …

Evaluation Of Strand Transfer And Development Lengths In Pretensioned Girders With Semi-Lightweight Concrete, Robert J. Peterman, J. A. Ramirez, J. Olek

JTRP Technical Reports

Indiana has been using lightweight aggregate consisting mostly of expanded shale in the production of prestressed concrete bridge girders for several projects. The lightweight aggregate has been used as partial replacement for regular gravel or crushed limestone coarse aggregate. This semi-lightweight concrete weighs around 2080 kg/m .

In a study sponsored by the FHWA, the current AASHTO equations for the calculation of transfer and development lengths of prestressing strand were found to be unconservative in the case of lightweight concrete members with unit weight less than 1 920 kg/m3 . This finding raises a question regarding the applicability of the …

Pile Design Based On Cone Penetration Test Results, Rodrigo Salgado, Junhwan Lee

JTRP Technical Reports

The bearing capacity of piles consists of both base resistance and side resistance. The side resistance of piles is in most cases fully mobilized well before the maximum base resistance is reached. As the side resistance is mobilized early in the loading process, the determination of pile base resistance is a key element of pile design. Static cone penetration is well related to the pile loading process, since it is performed quasi-statically and resembles a scaled-down pile load test. In order to take advantage of the CPT for pile design, load-settlement curves of axially loaded piles bearing in sand were …

Reconciled Platoon Accommodations At Traffic Signals, Jay Wasson, Montasir Abbas, Darcy M. Bullock, Avery Rhodes, Chong Kang Zhu

JTRP Technical Reports

The use of microprocessor-based traffic signal controllers introduced in the 1960s has allowed for the development of many new strategies to make traffic signal systems more responsive to traffic conditions. Many efforts have focused on the development of real-time, adaptive control strategies. While some of these strategies have been shown to improve intersection performance, there are several factors that have limited their deployment. Some of these include substantial capital cost, complicated calibration procedures, and the reluctance of practicing engineers to deploy strategies radically different from those currently in use. Therefore, lower cost strategies that are compatible with existing infrastructure continue …
