This book was released on 1975 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of efforts in Virginia to reduce the incidence of reflection cracking when portland cement concrete pavements or bases are overlayed with asphaltic concrete are reported. The methods of reflection crack reduction discussed are: (1) The use of sand as a bond breaker between portland cement concrete pavements and asphaltic overlays, (2) the use of a high tensile strength fabric as a stress relieving layer between two asphaltic concrete overlays of an old portland cement concrete pavement on a weak subbase, and (3) the use of two types of fabric as stress relieving layers between asphaltic layers and a concrete base on a very strong subbase and subgrade. The following conclusions were drawn. 1. Neither sand as a bond breaker nor high strength fabrics as stress relieving layers are effective in reducing reflection cracking where vertical joint movement (differential deflection) is a significant factor. 2. When differential deflections are greater than about 0.002 in (0.05 mm) reflection cracks form early. Such cracking is delayed for lower differential deflection but may occur as the magnitude and frequency of wheel loadings increase. 3. Both an asphalt impregnated polypropylene fabric and an unwoven, spun-bonded nylon fabric, when placed to span joints in portland cement concrete base and covered with an asphaltic concrete, overlay, are able to sustain the formation of reflection cracking in the overlaying layer without undergoing damage. 4. An asphalt impregnated polypropylene fabric spanning the joints in portland cement concrete pavements, and placed between the pavement and an asphaltic overlay, may be effective in reducing the infiltration of surface water to pavement sub-layers. There is some evidence that pavement pumping may be reduced by this method. 5. Both an asphalt impregnated polypropylene fabric and an unwoven, spun-bonded nylon fabric can delay the formation of reflection cracking. There is strong evidence, however, that such cracking is fatigue in nature and will eventually develop under the application of repetitive wheel loadings.

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.

This book was released on 1972 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report encompasses the results of a literature search, a survey of state highway departments, and an on-site field inspection of techniques used by state and federal agencies to control reflection cracking in asphaltic concrete overlays principally on portland cement concrete pavements. Procedures were generally for the purpose of isolating the overlay from the effect of movement in the underlying pavement or reinforcing the overlay. These procedures are made more effective by measures designed to prevent or minimize the underlying pavement movement. The methods found helpful in reducing reflection cracking include wire mesh reinforcement in the asphaltic concrete (AC) overlay; use of bond-breakers between the portland cement concrete (PCC) and the AC overlay; addition of an aggregate base course over the PCC followed by an AC overlay; pretreatment of the old PCC, such as mudjacking, subsealing, or cracking the old pavement by heavy rolling or with a hydraulic or pneumatic hammer; use of additives and other modifications in the AC composition. Many of the test installations inspected are 3 to 13 years old and in good to excellent condition. Normally, when using regular AC overlay procedures, reflection cracking begins to show up within 1 year or season cycle and cracks are larger than when special techniques are used. Results of the study indicate that there is no known 100% effective method for eliminating reflection cracking. Overall, a number of techniques have substantially delayed serious transverse reflection cracking, appear to have reduced longitudinal reflection cracking at pavement widening joints, and have reduced maintenance considerably.

This book was released on 1973 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fabric reinforcement was used in an attempt to prevent reflection cracking of two bituminous concrete layers overlying an 8-inch plain (unreinforced, unjointed) concrete base that was underlain by a portland cement stabilized subbase material. On these pavements it was expected that the extremely rigid base and subbase layers would reduce vertical motion to a minimum. Similar pavements constructed with no overlay reinforcement readily showed reflection cracking in the bituminous layers, presumably because of horizontal, thermally induced movements of shrinkage cracks in the concrete base.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to pavement designers, maintenance engineers, and others interested in methods and procedures for reducing reflection cracking of asphalt overlays. Information is provided on the use of paving fabrics and membranes in pavement rehabilitation. Reflection cracking of pavement overlays results in decreased pavement performance with respect to ride quality, structural support, skid resistance, and safety. The use of fabrics is one of the alternatives that are available to reduce or delay reflection cracking. This report of the Transportation Research Board describes the experiences of agencies in the use of fabrics and membranes for reduction of reflection cracking.
