Book Description
This synthesis will be of interest to pavement designers and others concerned with the design of asphalt concrete overlays. Information is presented on reasons for overlaying a pavement and on the vaious methods available for design of an asphalt overlay. A pavement overlay may be required because of inadequate ride quality, excessive pavement distress, reduced friction between tire and pavement, high user costs, or inadequate structural capacity for planned use. This report of the Transportation Research Boad discusses the current methods used for designing asphalt concrete overlays with emphasis on deflection-based and analytical procedures.

Book Description
"This study examined the current thin asphalt overlay practices implemented in Nebraska. To that end, the mechanical properties and performance characteristics of the two mixtures (i.e., SLX and SPH) were compared by carrying out laboratory tests such as dynamic modulus test, dynamic creep test, static creep-recovery test, semi-circular bending test, and Hamburg wheel tracking test. The laboratory test results were also used to characterize the material properties for pavement performance prediction simulation. Structural performance analysis was conducted using the MEPDG and finite element method in order to compare the pavement structures with the two different mixtures (i.e., SLX and SPH). In addition, a life-cycle cost analysis (LCCA) was performed to compare the economic benefits associated with the thin-lift overlay to the conventional overlay practice. This provided insights into how the thin asphalt overlay with the SLX mixture behaved compared to the previous practice, which replaced the old asphalt with the SPH mixture. Laboratory results clearly showed that the SLX mixture behaved similarly to the SPH mixture in terms of mixture stiffness, rutting potential, and cracking resistance. However, the Hamburg wheel tracking test found that the SLX mixture had greater moisture susceptibility, a result that requires more investigation. Pavement performance simulation results from finite element analysis showed that the rutting and cracking potential of the pavement with SLX thin overlay mixture was lower than the pavement with SPH mixture. MEPDG simulations predicted that both pavements would perform satisfactorily during their expected design life, but the LCCA indicated that the practice of using the thin SLX preservation technique can reduce both the agency's and user's costs compared to the conventional SPH rehabilitation practice. Both performance prediction results need to be compared to actual field performance data. Only one-year field performance is available to date, which needs to be continuously monitored to judge how both pavement structures perform" (page i).
