“…In cold climates, pavements may be subjected to a significant annual temperature differential of 75°C or more [9]. The most common causes of PDR failure are poor bond between the repair material and original concrete; thermal incompatibility between the repair material and existing concrete; and unsuitability of the repair material to the climate conditions are among [1].…”

“…The technical specifications of hot-applied sealants used in many countries are derived from the ASTM system, including in the United States (AASHTO M 324-12, SS-S-1401C) and China (JT/T740-2009). However, in recent years, many studies have questioned the ASTM system and indicated that the field performance of the hot-applied sealants could not be fully evaluated and predicted by laboratory tests (1)(2)(3)(4)(5)(6)(7)(8).…”

“…Thus researchers around the world have tried to evaluate the performance of the hot-applied sealant with new test methods. Soliman et al proposed new evaluation indexes on the basis of Superpave ® dynamic shear rheometer and bending beam rheometer tests, such as load drop tension at −30°C and G* at 5°C (2). In another study, Soliman and Shalaby used a glass transition temperature and lowtemperature stiffness to evaluate the low-temperature performance of the hot-applied sealant.…”

The relationship of viscosity to temperature is one of the most important factors in the application of hot-applied sealants. However, the present evaluation system cannot fully reflect the field performance of the sealants, given the lack of consideration of application conditions. A rotational viscometer and Rotor SC4-27 were used in this study to test the viscosity of hot-applied sealants, with viscosity at 50% torsional moment taken as the apparent viscosity. Nine kinds of sealants were tested in the temperature range of 160°C to 200°C. Analysis also was conducted to evaluate the correlation of the viscosity index with other indexes. The results showed no obvious correlation between them. Thus the viscosity index proposed in this study could be included in the present evaluation system in which the recommended pour temperature is 190°C, and the rotational viscosity is in the range of 1 to 3 Pa-s.

“…Crack sealants are widely used as a cost-effective preventive maintenance technique for extending pavement service life (1)(2)(3). In regions experiencing low temperatures, sealants are subjected to a large temperature differential that may exceed 80°C (2). In low-temperature climates, crack sealants should provide acceptable performance against adhesion or cohesion failures in the range of the service temperature at which the sealants are expected to be used (3).…”

When properly installed, hot-poured crack sealants are widely accepted as a cost-effective, routine preventive maintenance practice that extends pavement service life by 3 to 5 years. However, current ASTM specifications for selection of crack sealants correlate poorly with field performance. Therefore, an improved sealant specification and selection system is urgently needed. Recently, performance-based guidelines were developed by the pooled-fund North American Consortium expert group for selecting hot-poured bituminous crack sealants. The work proposed a sealant grade system for selecting hot-poured crack sealant on the basis of environmental conditions. A special effort was made to use the equipment originally developed by SHRP, which was used to measure binder rheological behavior as part of the performance grade system. The equipment and testing procedures used for performance grading of binders were modified in accordance with crack sealant behavior. The main objective of this study was to validate the low-temperature selection thresholds for the newly developed performance-based guidelines for selecting hot-poured crack sealants. Thresholds for the crack sealant bending beam rheometer, crack sealant direct tension test, and crack sealant adhesion test were validated. Nine hot-poured crack sealants were installed in four test sites experiencing low temperatures. The field performance of crack sealants was evaluated for 2 consecutive years by detailed field surveys. The field database consisted of 40 sections containing 647 cracks. Overall, results showed good correlation between the proposed selection thresholds and sealant performance in the field.
