Polymer modified asphalts have recently been the focus of much attention in the U.S. due to claims that polymer additives will lengthen the life of an asphalt pavement. Much of the published research on this topic has been concentrated on the effects of polymer modifiers on binder and mixture properties. The goal of this testing is to predict from laboratory testing the actual field performance of an asphalt concrete. Over the years, specifications have been developed for conventional asphalts that allow pavement performance to be predicted from certain binder tests. These conventional binder tests do not fully address the special characteristics of polymer modified asphalt binders and need revision to be an effective tool in predicting pavement service life. This paper presents the findings of a two-part laboratory research program intended to relate binder and mixture properties of polymer modified asphalts. The preliminary testing involved five asphalt binder types and a variety of binder and mixture tests. Promising test procedures were further investigated in the final testing program where ten asphalt binders were examined. Simple linear regression was used to determine the strength of a relationship between pairs of binder properties and mixture properties. The preliminary testing showed penetration, toughness and tenacity, and force ductility to have the most promise in predicting mixture performance. The final testing contained enough data to be analyzed with both simple linear regression and multiple regression. Penetration, toughness and tenacity, force ductility again were the test procedures that had binder properties that correlated well with mixture properties.

Ohio Department of Transportation has adopted the hot mix asphalt concrete containing polymer modifiers for use in the interstate highway pavement. Among the various reasons cited for the adoption of polymer modifiers are the favorable field experiences by ODOT, extensive literatures reporting enhanced performance, such as rutting resistance, low temperature thermal cracking resistance, and possibly fatigue endurance. However, despite these favorable findings, there are still cases involving premature failure of hot mixtures containing polymer modifiers. Concerns regarding optimum polymer content, compatibility between polymer additives and asphalt cement, proper mixing and compaction procedure remain to be resolved. Furthermore, performance based specifications to ensure production of desirable final asphalt concrete product require additional development. Questions regarding the suitability of Superpave binder testing procedures for the polymer-modified binders need to be clarified.

The pavement distresses including stripping, rutting, and low temperature cracking have been known to greatly decrease the service life of pavement. The simple laboratory tests are used to measure HMA's (Hot Mix Asphalt) fundamental engineering properties that can be linked back to the pavement distress-prediction models. It is envisioned that these simple laboratory tests would play a key role in the quality control of HMA mixtures. To minimize premature pavement distresses, it is imperative to investigate the relationship between the simple laboratory tests and pavement distresses. Moisture induced damage in asphalt concrete pavement, better known as stripping, is a primary cause of distresses in the Hot Mix Asphalt layer. AASHTO T 283 has historically been used to detect moisture damage of asphalt mixes. This method is established for the Marshall mix design process. However, the current hot mix asphalt design calls for the use of Superpave mix design procedure using the Superpave Gyratory Compactor. The differences in the mix design methods will most likely introduce significant differences in stripping test results. Therefore, there is a need to improve the AASHTO T 283 test procedure and to develop the new criterion for the Superpave HMA specimen's susceptibility to moisture damage. The experimental test program is divided into two parts: one part is a complete factorial experimental program for two aggregate sources with virgin asphalt binder, the second part is a partial factorial experimental program for the other two aggregate sources with polymer modified asphalt binders. The complete factorial experiment is used to identify and evaluate the contributions of the individual factors, along with all the possible interactions among the various factors. The partial factorial experiment, on the other hand, is used for validating findings from complete factorial experimental results. In the data analysis, the effects of different factors on dry tensile strength, freeze-thaw conditioned tensile strength, and tensile strength ratio (TSR) are investigated in this research. The effects of all the factors investigated in this research are summarized in this research. The recommendations for the proposed stripping test procedure for Superpave HMA are given finally. Rutting and low temperature cracking are also primary failure modes of Hot Mix Asphalt pavements. In the mid-1980s, polymer-modified asphalt concrete mixture has been widely used to minimize rutting and low temperature cracking failures of flexible pavement. In this research, three polymer modifiers are used in the laboratory test. The influences of the modifiers to rutting resistance and low temperature cracking resistance are investigated and regression procedures are performed in an attempt to develop mathematical relationships between pavement distresses properties and HMA's physical properties and strength properties obtained from the simple laboratory tests.

A five-year study has been performed to investigate the behavior of binders and asphalt mixtures containing polymer modifiers. The polymers were SBS, SBR, EVA, Ground Rubber, and polyolefin. These materials were used separately and in combinations with each other to change the characteristics of the binders and asphalt mixtures. The research included laboratory experiments to characterize the materials, and field projects to ascertain their performance. Four hot mix asphalt projects were conducted in Districts 15, 11, 25, and 10 in Texas, and two seal coat projects were constructed in Districts 6 and 17 in Texas. The testing results of the field and laboratory samples are presented in this report.
