“…In 2006, NDOT initiated a three-phase research study to identify the promising techniques to mitigate reflective cracking in AC overlays based on the earlier work of Utah and Texas DOTs. The findings from all three phases of this study have been reported in detail elsewhere in the literature (1)(2)(3)(4) and resulted in a preliminary performance-based mix design specification for an engineered SRC (ESRC) in Nevada. The new specification provided requirements for the ESRC aggregate properties and gradation as shown in Table 1.…”

“…The Nevada Department of Transportation (NDOT) uses various maintenance and rehabilitation repair strategies to improve the overall condition of the state’s pavement network. Asphalt concrete (AC) overlays have been one of the most commonly used methods for rehabilitating aged and deteriorated asphalt pavements caused by the combined effect of traffic loading and climate ( 1 ). Consequently, reflection of cracks from existing pavements becomes a major type of distress influencing the life of an AC overlay and controlling its long-term performance.…”

“…Several techniques have been applied to mitigate reflective cracking in AC overlays, including increased thickness of the AC overlay, stress-absorbing membrane interlayer, stress relief course (SRC), and fabric / geotextile membranes ( 1 ). Many factors may significantly influence the long-term performance of these techniques, including the specific conditions of the existing pavement and the combination of materials, traffic, and environmental conditions under which the technique has been applied.…”

“…Many factors may significantly influence the long-term performance of these techniques, including the specific conditions of the existing pavement and the combination of materials, traffic, and environmental conditions under which the technique has been applied. A recent survey by Habbouche et al indicated that none of these mitigation techniques was able to totally stop reflective cracking ( 1 ). Nonetheless, the use of SRC prevented reflective cracking for 3 years after construction and slowed down the rate of reflected transverse cracks until 5 years after construction.…”

Previous studies showed that the use of a stress relief course asphalt concrete (AC) interlayer (fine-graded asphalt mixture) between an AC overlay and the milled AC surface is a promising technique to mitigate reflective cracking. A performance-based mix design specification for an engineered stress relief course (ESRC) AC interlayer was developed and implemented in Nevada on two field projects. The projects were completed in summer of 2015 and 2016 on a U.S. route (US95, Las Vegas) and a residential road (Hidden Valley, Reno) in Nevada, respectively. The performance evaluation of field-produced mixtures collected during construction showed good stability, and increased resistance to fatigue and reflective cracking that can be attributed to the increased asphalt binder content and the finer aggregate gradation, thus making ESRC a promising technique to mitigate reflective cracking. This was also supported by the distress survey data collected throughout the up-to-date service life of the projects. The pavements with ESRC interlayer showed excellent performance thus far (after 2 to 3 years) when compared with the control sections, as demonstrated with a much lower level of cracking reflected in the AC overlay. A simple life cycle cost analysis was performed based on the observed field distresses from each project. The cost analysis showed that even though the ESRC mixture has a higher initial cost of materials, the agency and user life cycle costs per lane mile are lower and resulted in an average cost saving of 23%. In summary, based on the findings from this study, interlayer AC mixes designed using the presented ESRC performance-based mix design method should be used in Nevada.

“…Results showed that excessively soft asphalt mixture might decrease the structural performances of pavement under high temperature, while excessively hard asphalt mixture may cause the pavement to be brittle under low temperature, thereby resulting in surface cracking under loads. Habbouche et al [21] suggested that the experimental stress relief course (ESRC) buffer layer can be used as an effective method to relieve reflection cracks on asphalt coating. The effect of the ESRC buffer layer in inhibiting reflection cracks on asphalt coating was proved through a field comparative test.…”

Existing macadam base structures have poor resistance to bending deformation of pavement. The structural layer is challenged with serious cracking due to the long-term dynamic loads. Despite these issues, however, studies on reinforcement techniques for macadam base structure have been scarce. No reasonable and feasible method on how to improve the bending resistance of flexible base structures (e.g. macadam base structure) and prolong their bending fatigue life has yet been reported. Thus, this study proposed a method for reinforcing macadam base structures with geogrids to strengthen bending performance, anti-fatigue performance and dynamic stability of flexible base structures under different loading levels. The reinforced macadam base structure was investigated through a laboratory test of flexural-tensile strength and a three-point fatigue bending test. A cyclic loading test of reinforced and non-reinforced girder specimens was carried out under five stress levels. The effect of such a new reinforcement method in improving the bending fatigue properties of macadam base structures was analyzed by comparing the yield curves and fatigue lives of reinforced and non-reinforced specimens under different loading levels. Results demonstrate that the non-reinforced macadam base has poor bending resistance. The yield curve and fatigue life of non-reinforced specimens attenuated quickly as it approached the ultimate loading level. Non-reinforced specimens have low-cycle fatigue failures when the loads reach the 0.8 stress level and the ultimate displacement at failure is relatively small, accompanied by obvious failure surface. After geogrids are added, the fatigue life of specimens improved significantly. The yield curve shows no significant attenuation at a high loading level. The reinforced specimens can still maintain high-cycle fatigue failure under the 0.8 stress level and avoid the occurrence of low-cycle fatigue failures. Moreover, reinforced specimens can inhibit transmission of reflection cracks at midspan of cement-stabilized macadam base, delay the propagation of oblique shearing fractures close to the support, and strengthen the dynamic stability and durability of pavement structure with a macadam base. The conclusions of this study provide theoretical references to practical engineering applications of such new reinforcement technology for macadam bases.
