Laboratory Evaluation of Expedient Pavement Repair Materials


Book Description

Past work and current technical literature were reviewed to determine potential capping materials for expedient repair of small craters (less than 20 by 20 feet repair areas) in airfield pavements. Seven materials identified in the literature review were tested in the laboratory to develop information on their strength and cure requirements. Accelerated high alumina cement, magnesium phosphate cement, three commercial asphalt products and unsurfaced, well compacted aggregate were recommended for field testing as the most promising small crater repair materials.

Significant Findings from Full-scale Accelerated Pavement Testing


Book Description

"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 433: Significant Findings from Full-Scale Accelerated Pavement Testing documents and summarizes significant findings from the various experimental activities associated with full-scale accelerated pavement testing (f-sAPT) programs that have taken place between 2000 and 2011. The report also identifies gaps in knowledge related to f-sAPT and where future research may be needed. NCHRP Synthesis 433 is designed to expand the f-sAPT base of knowledge documented in NCHRP Syntheses 325 and 235, both with the same title of Significant Findings from Full-Scale Accelerated Pavement Testing. f-sAPT is the controlled application of a wheel loading, at or above the appropriate legal load limit, to a pavement system to determine pavement response in a compressed time period. The acceleration of damage is achieved by one or more of the following factors: increased repetitions, modified loading conditions, imposed climatic conditions, and thinner pavements with a decreased structural capacity which have shorter design lives"--







Fiberglass-reinforced Plastic Surfacing for Rapid Runway Repair by Naval Construction Forces


Book Description

This report documents exploratory research conducted to develop a preliminary concept for repairing bomb-damaged runways with prefabricated fiberglass-reinforced plastic membranes. The membranes would function as traffickable caps over backfilled craters. A structural analysis has been completed using the finite element method and a design is presented for a membrane to be traffic-tested under simulated F-4 aircraft wheel loads at the Rapid Runway Repair Test Facility of the Air Force Engineering and Services Center/Research Division at Tyndall AFB, Florida. Methods for joining panels to form large membranes and a tiedown method are discussed. A general concept for rapid runway repair by the Naval Construction Forces using table-of-allowance (P25 and P31) equipment is presented. (Author).
