Polymer modified asphalt binders
TLDR
A review of research that has been conducted on polymer modified binders over the last three decades can be found in this paper, where the elastic recovery test is good at determining the presence of polymers in an asphalt binder but is less successful at predicting field performance of the pavement.About:

Implementation and thickness optimization of perpetual pavements in Ohio.
Abstract: CICHOCKI, PAUL F., M.S., July 2015, Civil Engineering Application of Highly Modified Asphalt (HiMA) Binders in Implementation and Thickness Optimization of Perpetual Pavements in Ohio Director of Thesis: Shad M. Sargand This research explores using highly modified asphalt (HiMA) mixtures as an alternative to standard materials in furtherance of making perpetual pavements thinner in Ohio. Previous projects on I-77, US Route 30, and US Route 23 have demonstrated that reduced strains were possible with standard materials at greater pavement thicknesses. Thinner and superior pavements with improved binder have the potential to reduce the construction cost of perpetual pavements, despite the higher unit cost of materials. Four test sections containing HiMA with varying base layer thicknesses of 8 in, 9 in, 10 in, and 11 in were installed at the Accelerated Pavement Loading Facility (APLF) in Lancaster, Ohio. To successfully compare the effect of the HiMA in the various thicknesses, the 11 inch section acted as a control with a non-modified base layer. Each pavement was subjected to 10,000 passes of a single axle load of 9000 lbs at two pavement temperatures of 70F and 100F. Rutting on the surface of the pavement was measured using a rolling wheel profiler after 100, 300, 1000, 3000, and 10,000 wheel passes, while pavement distresses were found at the bottom of the base and intermediate layers in the longitudinal and transverse directions after wheel passes of 100, 3000, and 10,000 at wheel loads of 6000, 9000, and 12,000 lbs. The serviceability of the pavements was determined by comparing the longitudinal tensile strains within the base layer of 4 each pavement to calculated fatigue endurance limits (FEL) found by using flexural stiffness standards from NCHRP Design Guides in addition to Kansas researchers to determine which sections met the perpetual design concept. Following the testing, it was determined that the four test sections showed no significant rutting damages after being subjected to 20,000 passes of a single axle load of 9000 lbs. Additionally, the thinnest section produced maximum average strains higher than the calculated fatigue endurance threshold at 100F using the NCHRP 9-44A equation; however, using the Kansas researchers approach, all four test sections were found to have lower longitudinal strains than the calculated FEL. The findings from this study have shown that the modified binder provides substantial improvement in rutting but did not show significant improvements in structural support when comparing the modified asphalt to standard asphalt mixtures.

Classification of asphalt binders into simple and complex binders
TL;DR: The NCHRP 9-10 Project as mentioned in this paper evaluated the suitability of using the Superpave binder and mixture test system for modified asphalt binders, and the results indicated that modified binders will be used more in the future and that there are major concerns regarding the applicability of the superpave PG-grading system to modified asphalt binder.

Characteristics of polymers and polymer-modified binders
TL;DR: In this article, the properties of a number of polymers commonly proposed for polymer-modified bitumens (PMBs) were studied to suggest a way to select the polymer suitable for the required application; the prediction of the performance in the final application would allow bypass of the tests on PMBs and asphalt mixtures.
