Turn to the Tech Briefs for the Latest LTPP Research Findings
Engineers, researchers, and others trying to keep
up with new information and products from the long-term pavement performance
(LTPP) program can now turn to Tech Briefs, a new series of summaries of
recent LTPP reports. Each brief provides a concise summary of the findings
of a recent research project; outlines the impact on current practices;
and describes test methods, design guidelines, and other products that
may result from the research.
The following Tech Briefs have recently been published:
- LTPP Data Analysis, Validation of Guidelines
for k-Value Selection and Concrete Pavement Performance Prediction (Publication
No. FHWA-RD-97-035)
- Pavement Treatment Effectiveness, 1995 SPS-3
and SPS-4 Site Evaluation, National Report (Publication No. FHWA-RD-97-029)
- Improving Accuracy of Unbound Resilient Modulus
Testing (Publication No. FHWA-RD-97-090)
- Improved Guidelines for Users of the 1993 AASHTO
Flexible Pavement Design Procedures (Publication No. FHWA-RD-97-091)
- LTPP Data Analysis: Frequently Asked Questions
About Joint Faulting with Answers from LTPP (Publication No. FHWA-RD-97-101)
- Advanced Methods for Using FWD Deflection-Time
Data to Predict Pavement Performance (FHWA-RD-97-093)
A limited number of copies of the Tech Briefs are available from FHWA's Research
and Technology Report Center (phone: 301-577-0906; fax: 301-577-1421). The Tech
Briefs are also available from the National Technical Information Service (phone:
703-487-4650 or 800-553-6847; fax: 703-321-8547) and from the LTPP program's
home page: www.fhwa.dot.gov/pavement/ltpp/index.cfm.
The Tech Briefs are intended for senior-level pavement engineers, materials
engineers, and pavement management engineers at State highway agencies, as well
as contractors, LTPP coordinators, libraries in highway agencies, and others.
