Book excerpt: The Illinois Department of Transportation (IDOT) spends two million dollars annually on reflective crack control treatments; however, their cost-effectiveness has never before been reliably determined. The study evaluated the cost-effectiveness of IDOT reflective crack control system "A", which consists of a non-woven, polypropylene paving fabric, placed either in strips longitudinally over lane-widening joints or over the entire pavement ("area" treatment). Performance of 52 projects across Illinois was assessed through crack mapping and from distress and serviceability data in IDOT's Condition Rating Survey (CRS) database. Comparisons of measured reflective cracking in treated and control sections revealed that system "A" retards longitudinal reflective widening crack development, but does not significantly retard transverse reflective cracking. However, both strip and area applications of these fabric treatments appeared to improve overall pavement serviceability, and were estimated to increase rehabilitation life spans by 1.1 and 3.6 years, respectively. Life-cycle cost analyses (LCCA) found strip and area reflective crack control treatments to be marginally cost effective, where a 4.5% reduction in life-cycle costs was estimated, for medium-sized projects [between 1 and 6 mi (1.6 and 9.7 km) of two-lane road]. Small projects [under 1 mi (1.6 km) of two-lane road] showed a breakeven level of cost-effectiveness, while large projects [over 6 mi (9.7 km) of two-lane road] showed a 6.2% savings in life-cycle costs. Permeability testing of field cores taken over transverse joints showed that waterproofing benefits can exist after reflective crack appearance, which explains why serviceability was improved with area treatment even though crack development was not retarded. Guidelines for establishing and monitoring future experimental sections were also developed.

Available in PDF, EPUB and Kindle. Book excerpt: Crack reflection through a road structure is one of the main causes of premature pavement deterioration. This is a widespread problem in many countries and highway maintenance authorities are having to find economic means of repairing and upgrading their pavements. This book is the eagerly awaited state-of-the-art report which considers all different aspects of the subject including assessment and use of overlay systems.

Available in PDF, EPUB and Kindle. Book excerpt: Reflection cracks are caused by discontinuities (cracks or joints) in underlying layers, which propagate through a hot-mix asphalt (HMA) overlay due to continuous movement at the crack prompted by thermal and traffic loading. If the new overlay is bonded to the distressed layer, cracks in the existing pavement usually propagate to the surface within one to five years and even as early as few months have been reported. Excessive seasonal temperature variations and movements of a cement-treated base layer may also result in shrinkage cracking, which extends to the pavement surface to cause reflection block cracks. Reflection cracking leads to premature failure of overlays by allowing water infiltration through the cracks, which cause stripping in HMA layers and weakening and deterioration of the base and/or subgrade. Since the early 1930s, considerable resources and efforts have been spent to find new and relatively inexpensive techniques to delay reflection cracking. Different methods, including the use of interlayer systems (e.g., glassgrid, stress absorbing membranes, paving fabrics, etc.) and rubblization, have been suggested for enhancing pavement resistance to reflective cracking. Experimental investigations of these crack control treatments indicate that their performances have been mixed and cannot be considered conclusive. Louisiana has experience with various techniques and treatments to control reflection cracking since the 1970s; however, the cost-effectiveness and performance of these methods have not been reliably evaluated. In addition, scientific evaluation and testing of these treatment methods was not performed on many projects. To ensure successful control of this distress and effective allocation of maintenance funds, there is a critical need to assess the performance of pavement sections across the state built with various treatment methods and to determine the most cost-effective techniques to delay or to prevent reflection cracking in composite pavements.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents guidelines for selection of asphalt-overlaid concrete (AC/PCC) pavements for rehabilitation, collection of distress data, recognition of AC/PCC pavement distress modes, nondestructive deflection testing, materials sampling, and overall project-level evaluation. Key condition indicators (distress, rutting, roughness, serviceability, and CRS) were examined to address their usefulness in AC/PCC rehabilitation project selection. Critical levels for these indicators were identified, and available prediction models were investigated for use in rehabilitation programming. The project-level evaluation procedure includes guidelines for field and laboratory data collection and analysis for structural evaluation, functional evaluation, drainage evaluation, and AC surface material evaluation. A procedure was developed for backcalculation of AC/PCC pavement layer elastic moduli from deflection measurements, and guidelines were developed for practical interpretation of the backcalculation results. The recommended evaluation procedure relies on conventional testing and evaluation methods (visual surveying, deflection testing, coring, materials testing, etc.). New technologies (e.g., ground-penetrating radar, infrared thermography) are developing which have potential for use in pavement evaluation. These technologies are also reviewed in this report.
