SHRP-LTPP Specific Pavement Studies


Book Description

The Specific Pavement Studies (SPS) portion examines specially constructed pavements, which will help develop better understanding of the effects on performance of a few targeted factors not widely covered in General Pavement Studies (GPS). SPS also explores options for construction of new pavements, the application of maintenance treatments to existing pavements, and the rehabilitation of distressed pavements. This report summarizes the status of SPS as of June 30, 1992.




SHRP-LTPP Monitoring Data


Book Description

This report summarizes the LTPP monitoring data collection activities for inclusion in the National Pavement Performance Database. The pavement condition monitoring data include identification of surface distress, profile measurements, deflection testing results, and surface friction measurements. The report also describes traffic, climate, maintenance, rehabilitation, and seasonal monitoring and data collection. Other results and products of the 5-year pavement condition monitoring activity are listed.




SHRP-LTPP Overview


Book Description

This report provides an overview of the first 5 years of the Strategic Highway Research Program Long-Term Pavement Performance (SHRP-LTPP) program. The background, LTPP history, activities and approaches, and decision-making processes of the program are detailed. Included are summaries of the studies initiated for general and specific pavement types, the characterization of pavement materials, monitoring activities, the LTPP database and Information Management System, data analysis, traffic data collection and analysis, as well as a summary of the contributions made by international participants. The general LTPP program is described and the expected results, products, and benefits are also outlined.




Bearing Capacity Of Roads Volume 1


Book Description

This book is an outcome of the sixth conference on bearing capacity of roads and airfield held in Lisbon, Portugal. It focuses on railway tracks and covers following topics: bearing capacity policies, concepts, costs and condition surveys; analysis and modelling; design and environmental effects.

SPS-5 and SPS-6 SHRP Data Collection


Book Description

This project required the completion of Construction Data Forms for the Strategic Highway Research Program's (SHRP's) Specific Pavement Studies (SPS) Experiment Number 5, The Rehabilitation of Asphalt Concrete Pavements, and Experiment Number 6, The Rehabilitation of Jointed Portland Cement Concrete Pavements. In Arizona, the SPS-5 experiment construction was done in the eastbound travel lane of Interstate Highway 8, between mileposts 159 and 161 in southwestern Arizona. Eleven test sections were constructed for the experiment, with eight as set forth in SHRP guidelines. In addition, two additional sections were constructed, and one designated as the control section, for a grand total of eleven sections.




SHRP-LTPP Materials Characterization


Book Description

The Strategic Highway Research Program (SHRP) developed two materials characterization programs: one for field sampling, and another for laboratory testing. The SHRP field materials sampling and laboratory materials testing program encompassed all 50 states; 10 Canadian provinces; and Puerto Rico. This report documents the development and execution of these programs for both the General Pavement Studies (GPS) and the Specific Pavement Studies (SPS). These topics are described separately here, although they are linked inherently. Suggestions are given for future materials characterization within the Long-Term Pavement Performance program as it continues under the Federal Highway Administration.
