This book was released on 1992 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A survey of all 50 United States was conducted in September of 1990 to determine the state of the art of crack sealing procedures on flexible asphalt concrete pavements. The results were tabulated and a summary report prepared. A meeting was held at the U.S. Army Cold Regions Research and Engineering Laboratory to discuss the draft report; the comments and suggestions received were incorporated into this report. At the meeting the group identified the need for a trade organization to develop uniform specifications and terminology and to promote proper equipment, methodology, materials, training and education in the pavement crack sealing industry.

Available in PDF, EPUB and Kindle. Book excerpt: This study used over forty-four lane miles of test site to gather up to three years of comparative performance data on thirteen crack sealants. The data indicates that the more durable, high ductility materials when applied in a band-aid configuration can be expected to give significantly better performance than the lower ductility materials used by the Utah DOT prior to 1983. Evaluation of sealant placement procedures indicates that routing is a questionable practice, and that the hot compressed air lance may significantly improve the performance of materials placed during cold or wet conditions. Evaluation of UDOT maintenance activities indicates that sealant melters cannot achieve or maintain the required sealant application temperatures under colder winter conditions. The efficiency of melter units should be improved or not operated under those conditions. More accurate temperature gauges on melter units should be acquired. Inaccurate gauges may cause impaired sealant performance and safety.

Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of this study was to develop criteria to improve the effectiveness of Utah's flexible pavement crack sealing practice. The methodology involved field measurements of seasonal variation in crack width and in-depth interviews of Department members at various levels of management in maintenance, materials, construction, and research. Other states were queried by questionnaire in order to obtain a comparative base on with to evaluate Utah's practice. Findings indicate that flexible pavement cracking is a significant problem in the Far West, Rocky Mountains, Great Lakes, and New England. Criteria to determine when to seal (fill) cracks, and materials or techniques to be used vary widely. Choice of materials if affected by storage requirements and equipment available. Prepackaging of materials especially designed for crack sealing has resulted in improvements in control of mix and material properties; further gains can be anticipated as mix design improves and material specifications become more exact.. Low temperature and freeze thaw cycles significantly affect the amount of thermal cracking and the performance of crack sealant. Poor rideability, increased pavement deterioration, obscured traffic markings, lowered skid resistance can result from inappropriate selection and installation of crack sealants. Ductile sealants such as Crumb rubber/asphalt cement mixes, in combination with routing appear to offer substantial gains in sealant life and performance. These gains are partially offset by increased installation cost and hazard to the operator. Existing data is insufficient for benefit/cost analysis.

Descriptions of the density of occurrence and the severity of each type of distress manifestation are made to conform to standard words which precisely express the relative density or severity on a scale of 1-5. Probable causes of each distress manifestation are presented, together with comments on progressive deterioration or other behaviour which might affect remedial treatment. Possible remedial measures are included under each distress manifestation.

Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this project is to evaluate the ability of placing joints to control random asphalt pavement cracking. Asphalt pavements are subjected to thermals stresses due to extreme low temperatures in the northern climate. These thermal stresses cause the formation of random unsealed cracks. These unsealed cracks allow moisture to infiltrate the subgrade and base. This moisture can cause stripping of the asphalt binder on the walls of the cracks, causing the pavement structure to weaken. The weakened pavement may form depressions at the cracks, which lead to bad ride characteristics and may also cause secondary cracking. Sawing joints into new asphalt pavements at regular intervals may help control the location of thermal cracking in flexible pavement. Sawed joints are easier to fill initially and maintain in the future. Early sawing and sealing joints into the pavement controls the infiltration and reduces the stripping of asphalts"--p. 1.
