“…Several approaches have been used to evaluate the performance of interlayer systems including field crack surveys (6), laboratory tests to determine interface shear stiffness or bulk and fracture material characteristics (7)(8)(9), accelerated pavement tests to determine the number of load repetitions to failure (10), and numerical modeling (11). Until recently, measurement of field cracks appeared to be the most effective approach to evaluate the performance of overlays (12). This study introduces a method to identify field reflective cracking by using ground-penetrating radar (GPR) and crack severity and extent surveys.…”

A method to investigate the effectiveness of interlay systems in hot-mix asphalt (HMA) overlays to retard reflective cracking is introduced. Significant research has been conducted on developing techniques to reduce reflective cracking in HMA overlays. Many interlayer systems have been used in the field; some showed no structural or economical benefits, while others could reduce reflective cracking in the short term. However, long-term and quantitative benefits for many of these techniques have not been realized. Hence, this research fulfills the need to quantify the effectiveness of interlayer systems in delaying or abating reflective cracking–it proposes a systematic approach to identify reflective cracking and a conceptual index to evaluate interlayer systems. Ground-penetrating radar and a video integration system are used to detect surface cracks in overlays as well as joint opening and dowel bars in existing portland cement concrete pavements. Transverse cracks that exist over a joint are classified as joint-associated reflective cracks. Other transverse cracks are categorized as non-joint-associated transverse cracks. These cracks are not considered reflective cracks. A weight function is introduced to incorporate crack severity. Finally, two performance indices are introduced: reflective cracking appearance ratio and transverse cracking appearance ratio. By means of these new indices, the effectiveness of four interlayer system types used in Illinois is quantified: nonwoven reinforcing fabric with asphalt binder, sand antifracture, interlayer stress-absorbing composite, and modified leveling binder.

“…After three years of service, the interlayer section contained 36 percent less reflective cracks than the control section (Blankenship et al 2005). Wisconsin Department of Transportation also documented their use of crack relief interlayers for several overlay projects from 1996 to 2002 (Makowski et al 2005). In three out of four projects, there was a clear delay of cracking (42 percent average crack reduction) when using a pavement overlay with an interlayer.…”

Asphalt binder is typically modified with poly(styrene-butadiene-styrene) (SBS) type polymers to improve its rheological properties and performance grade. The elastic and principal component of SBS polymers is butadiene. For the last decade, butadiene prices have fluctuated and significantly increased, leading state highway agencies to search for economically viable alternatives to butadiene based materials. This paper reports the recent
