Prevention of Reflective Cracking in Pavements available in PDF, EPUB and Kindle. 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.

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.

It involves cracks or breaks in the underlying layers of the asphalt pavement because of movements experienced due to an original crack. Due to the continuous movement of existing asphalt pavements, discontinuities like joints and cracks spread through the pavement leading to reflection cracking. It becomes a challenging issue that troubles many engineers particularly those who work in the road maintenance and rehabilitation industry. Research into the problem can reveal important ways that the problem can be dealt with to offer a solution to an issue that has remained troublesome for many years. The need for rehabilitation methodologies that will improve the performance of asphalt pavements continues to grow create the need for a detailed review of existing treatment methods that can reduce the incidences of reflective cracking. This research summarized the current published literature until 2022 and identified the methods used in some states on how they deal with the reflective cracking problem that facing the roads. A Questionnaire survey consisting of several important points was created and sent to transportation agencies (departments of transportation) (DOTs) in all of the fifty states in the U.S. Replies from 20 states were and carefully investigated for figuring out the details related to the reflective cracking and remedies. The most prominent of these points were about whether the state faces this problem in their roads. Some of the questions asked where to inquire the details of how the DOTs determine the crack, the time for the first crack to appear and beginning to become a serious issue threatening the roads. The questionnaire also include the prevention as well as the treatment methods for solving the reflective cracking problem. The goal of this survey is to compare how each state DOTs deal with the reflective cracking issue and to benefit from the DOTs experience to find the most appropriate way to prevent and treat the reflective cracking keeping in view to achieve a good quality of the pavements and reduction in the cost of repair and maintenance for the best economic factor.
