Available in PDF, EPUB and Kindle. Book excerpt: This investigation is part of CRREUs on-going characterization of pavement performance in seasonal frost areas. As part of the research, CRREL conducted several field studies for the Federal Aviation Administration (FM) on the response of airport pavements during thaw-weakening periods at three civil airports in Wisconsin, where the design freezing index in the area was around 900 to 1100oC-days and frost penetration ranged between 1250 to 2000 mm. This study focused on the performance of Portland Cement Concrete (PCC) pavements during the spring thaw-weakening period. The sites were instrumented with subsurface thermocouples and Falling Weight Deflectometer (FWD) tests were conducted during the spring thaw period at the center of the slab and across the joints. An analysis of the FWD data and backcalculation of the layer moduli using ILLIBACK and WESDEF was conducted. Unique relationships between the FWD deflections and the subgrade modulus and coefficient of subgrade reaction were obtained. Additional relationships were developed using the FWD deflections, PCC thickness and the horizontal tensile stress at the bottom of the PCC layer. A relationship between load transfer across joints and FWD deflections was also developed. On the basis of the relationships obtained in this study, a methodology for evaluating PCC pavements during spring thaw was developed. However, this methodology needs to be verified for other subgrade types and areas with other design freezing indices.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to develop a method to predict the timing of weight limits on secondary highways in Wisconsin. Two types of weight limits are of interest: overloads when the pavement is frozen and weight restrictions during thawing and post-thawing recovery period. To meet this objective, three sections of secondary highways with flexible pavements were instrumented and monitored to determine how freezing, thawing, and post-thaw recovery affect pavement stiffness. Data collected from these sites were used to develop a computer model (UWFrost) that can be used to predict seasonal changes in the support capacity of pavements.

Available in PDF, EPUB and Kindle. Book excerpt: Despite the growing popularity of the crack and seat technique, little guidance is available for use in evaluating and designing overlays for cracked and seated airfield pavements. Towards solving this problem, a case study was undertaken to compare in-situ characteristics and overlay requirements of three different pavement sections at Suffolk Municipal Airport, Virginia. Nondestructive testing was used to determine the in-situ pavement properties and visual surveys were conducted to assess the condition rating of the pavements. The results of the NDT testing program were used to predict and compare the PCC layer moduli and to design AC overlays. The results of the study indicate that: (1) while the use of the crack and seat technique appears to be effective, reflective cracking is not eliminated: (2) the strength of the PCC layer is significantly reduced after cracking and seating and hence, thicker AC overlays are required and (3) a greater degree of cracking before placing the overlay would have been helpful. The uses of a modified FAA flexible pavement procedure for the design of AC overlays is recommended as an interim procedure. NDT testing as a construction quality control device during breaking of the PCC is also recommended.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to make an assessment of the relative performance of recycled versus new asphalt concrete pavement surfaces constructed for airport facilities. To make this assessment, pavement condition index (PCI) surveys and tests on core samples from the hot-mix recycled pavements located on the airports at Needles, California and Valley City, North Dakota were conducted. Both pavements have a condition rating of very good. The survey and test data were compared with those for recycled highway and virgin material Navy airfield pavements. The recycled pavement at Needles is performing as good as those Navy pavements constructed with virgin material. The recycled pavement at Valley City has a higher deterioration rate than the Navy pavements but this could be attributed to the harsh climate found in North Dakota. The results of this study show that hot-mix recycling was successful at these airports but additional studies are required to determine the applicability of Asphalt Concrete (AC) recycling for reconstruction at all airports. Keywords: Recycled concrete, asphalt, pavement surfaces, airport facilities, Navy airfield pavements, hot-mix recycling.

This book was released on 1990 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four different pavement test sections were subjected to freeze-thaw cycling in CRREL's Frost Effects Research Facility (FERF). The test sections, each 610 cm in length, consisted of 1) 15.2 cm of asphalt concrete pavement over a clay subgrade, 2) 15.2 cm of asphalt concrete over 10.2 cm of crushed gravel over a clay subgrade, 3) 5.1 cm of asphalt concrete over 17.8 cm of crushed gravel over 20.3 cm of clean sand over a clay subgrade, and 4) 5.1 cm of asphalt concrete over 25.4 cm of crushed gravel over 12.7 cm of clean sand over a clay subgrade. Thermocouples were imbedded throughout the pavement structure and subgrade. During the thawing periods, deflection measurements were made at four locations in each test section using a Dynatest Falling Weight Deflectometer (FWD). The results of the deflection measurements are presented here. An analysis was done to quantify the subgrade strength based solely on FWD measurements. It was also shown that a relationship existed between thaw depth and FWD measurement in the subgrade.
