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:

Thermoplastic rubbers for the modification of bitumens: improved elastic recovery for high deformation resistance of asphalt mixes
C P Valkering,W Vonk +1 more
TL;DR: In this paper, the effect of bitumens with thermoplastic rubbers of the styrene-butadiene-styrene (SBS) type was studied in experiments in a Laboratory Test Track (LTT), which offers the closest simulation of asphalt performance in practice.
Coatings to improve low-quality local aggregates for hot mix asphalt pavements
TL;DR: In this paper, a laboratory investigation was conducted wherein smooth, rounded, siliceous river gravel aggregates were coated with fine-grained polyethylene, carpet co-product, or cement plus styrene butadiene rubber latex and used to prepare hot mix asphalt concrete specimens.
Constructability of polymer-modified asphalts and asphalt-aggregate mixtures in alaska
TL;DR: In this article, the compatibility of the polymer and the asphalt cement was investigated using fluorescent microscopic images and elasticity tests, and three traditional binders were analyzed using Superpave binder tests.
Limit the strain at the bottom of an asphalt pavement, and what do you get? : a perpetual pavement
TL;DR: In this paper, the authors focused on the performance of long-lasting asphalt pavements and enhancing pavement endurance, and discussed how the misconception regarding the inevitability of fatigue cracking in asphalt pavement came to be, and how researchers have established a reasonable level for the fatigue endurance limit for asphalt mixtures.
