This paper describes in detail the laboratory and field evaluation of runways at two airports: Double Eagle II at Albuquerque and Sierra Blanca at Ruidoso, New Mexico. Field skid resistance test, Falling Weight Deflectometer (FWD) test, and coring are carried out. Cores and soil samples are collected and tested in the laboratory. The CBR values and the skid numbers were compared to the tables in Advisory Circulars 150/5320-6D and 150/5320-12C to make an assessment. The modulus values from FWD data are presented in a 2D contour plot to determine the distress area of each runway. The structural health of the pavement of runway 17-35 at Double Eagle II airport is in a good condition while runway 4-22 of the same airport is not in good condition based on the resilient modulus and CBR values. As for Sierra Blanca airport, runway 6-24 is in a good condition while the surface of the runway 12-30 needs attention.

The American Association of State Highway and Transportation Officials (AASHTO) through the National Cooperative Highway Research Program (NCHRP) has spent over $7 million developing a new mechanistic-based design method, which is presented in the Mechanistic-Empirical Pavement Design Guide (MEPDG). This provides a golden opportunity to emphasize the project level aspects of pavement management. Pavement management system (PMS) data, carefully taken and expanded, can be used directly to calibrat...

The objective of the study was to determine whether the Federal Aviation Administration (FAA) standards used to determine the appropriate thickness for hot mix asphalt and concrete airfield pavements are in accordance with the FAA standard for a 20-year life requirement. FAA airport pavement design standards, and related references, including some unpublished FAA technical reports and full-scale test results, were reviewed. The effects of many parameters, directly used in the failure model and i...

Rutting of flexible pavement is a load-induced phenomenon. It is caused by a combination of densification and shear deformation of any layer of the pavement structure. Severe rutting was observed on the Taxiway A at the Sacramento International Airport. The Runway 16R-34L and associated taxiways at the airport were originally constructed in 1965–66 and were placed in operation in 1967. The entire airfield received a strengthening overlay in 1979 and a second strengthening overlay in 1995. The pa...

The purpose of this paper is to present the findings of the investigation undertaken to determine the possible causes of the rutting observed on the Taxiway A at the Sacramento International Airport and examines the optimum remediation strategies selected. Vigorous pavement selection criteria were implemented to develop a design matrix for comparing various pavement rehabilitation options and selecting the one with the highest ranking. Through careful investigation, analysis, and design involvin...

This study evaluates airfield pavements’ functional- and structural-condition to determine the most economical maintenance method. As a part of the analysis, Pavement Condition Index (PCI) for several runways, taxiways, and aprons has been determined by MicroPAVER. Structural evaluation of airport pavements has been performed by Falling Weight Deflectometer (FWD) test. Evaluation of Layer Moduli and Overlay Design (ELMOD) also determines the required overlay thickness based on the E-values, i.e....
