“…Finally, the dynamic modulus master curves at a reference temperature of 21.1°C were constructed based on the timetemperature superposition principle. A sigmoidal function, as shown in the following equation, was used in fitting the master curve (Singh, Zaman, & Commuri, 2011a, 2011b:…”

Despite the environmental and compaction benefits of warm mix asphalt (WMA), several researchers have expressed concerns over laboratory and field performances of WMA mixes. In this study, a wide range of laboratory tests, namely, dynamic modulus, creep compliance, fatigue, moisture damage, and rutting, was conducted to evaluate the performance of different types of WMA mixes. For this purpose, three WMA mixes, consisting of one mix produced using a zeolite-based WMA additive (containing water), one surface course mix, and one base course mix, the latter two produced with a chemical-based WMA additive with surfactant technology, were collected from different field projects in Texas. In addition, three hot mix asphalt (HMA) mixes with aggregate gradations similar to those of the collected WMA mixes were produced in the laboratory to compare the performance of WMA and HMA mixes. Overall, the WMA mixes yielded lower stiffness, reduced potential of low-temperature cracking, lower fatigue resistance, and a higher rutting potential compared with their HMA counterparts. However, a mixed trend of moisture-induced damage potential was observed for WMA and HMA mixes, when evaluated using retained tensile strength ratio (TSR) and stripping inflection point (SIP) obtained from the Hamburg wheel tracking (HWT) test. In other words, no correlation was found between TSR and SIP values, indicating that passing a TSR test does not guarantee better performance of a mix when tested using an HWT. The results from this study reveal that performance of a WMA mix widely depends on the technology and the type of other additives (e.g. anti-stripping agent) used. The findings of this study are expected to be useful to pavement professionals to better understand the performance of WMA mixes and to develop a database of input parameters for the Mechanistic-Empirical Pavement Design Guide.

“…Two main aspects were identified: one that focused on the validity of the implemented performance prediction models and another that focused on data collection methods to predict pavement performance. Previous studies reported that the various models implemented in the MEPDG had certain limitations that were improved through several revisions (4)(5)(6)(7). Other studies by Roberts et al (8) and Kweon and Cottrell, Jr., (9) showed that development of new testing methods and updates of data collection protocols resulted in more accurate MEPDG predictions.…”

The objective of this study was to propose an approach to integrate AASHTOWare Pavement ME Design software into pavement preservation strategies of the Rhode Island Department of Transportation. The use of Pavement ME Design software could assist in the prioritization of mitigation alternatives; this procedure would optimize resources in Rhode Island. Four representative pavement sections on state highways in Rhode Island were selected and then analyzed with the Pavement ME Design software. Weigh-in-motion traffic data also were collected from nine stations in Rhode Island to establish representative state traffic patterns. This information was used as input to Pavement ME Design, and the predicted performance measures (i.e., international roughness index, rutting, longitudinal cracking) were then used to determine when the typical Rhode Island pavement mitigation alternatives [e.g., crack seals; level and overlay; mill and overlay with and without friction course; paver placed elastomeric surface treatment; rubberized chip seals; reconstruction and reclamation; and stress-absorbing membrane interlayer (SAMI)] were triggered. In addition, a cost-based approach and an incremental benefit–cost alternative prioritization method were analyzed to determine the most cost-effective alternatives and the most beneficial alternatives, respectively. On the basis of the analysis, the Pavement ME Design software was found to have potential for use in the enhancement of pavement preservation strategies. Crack seals, rubberized chip seals, and SAMI were found to be the most cost-effective and the most beneficial of all alternatives assessed.

“…For example, at Level 1, the asphalt binder and the HMA are tested in the laboratory to measure dynamic modulus. However, the measurement of dynamic modulus in the laboratory is not always feasible because of the tedious experiments and it may also take several days to develop a single master curve [6]- [8].…”

“…Several prediction models are available in the literature for estimating the dynamic modulus of HMA. These models use the volumetric properties of mix, aggregate graduation, loading frequency and viscosity of an asphalt binder to predict dynamics as discussed on literature by [8]- [13]. Dynamic modulus testing characterizes asphalt mixture as a linear viscos-elastic material over a wide range of temperature and loading frequency.…”

Abstract-The complex moduli relationship related mixture moduli to temperature and time rate of loading has been an integral part of several mechanistic-empirical (M-E) design procedures used throughout of the world. Seven asphalt concrete mixtures of different types of polymer modified binders (PMB) were produced in a laboratory to modify performance of asphalt mixture. The main role of this research is to evaluate the influence of these polymer modifiers on the pavement performance of asphalt mixture with the dynamic modulus, |E*| of hot-mix asphalt (HMA) mixture indicator in a laboratory test for Mainroad Western Australia and Fulton Hogan. In this study, the influence of temperature, loading frequency, and confining pressure on the dynamic characteristic of asphalt mixture were analysis, master curves of dynamic modulus of HMA mixtures were developed and data's were interpreted. Results showed that AC10 5.7% A35P (EVA) M7 B5, AC10 5.7% C450 M10 B5 and AC10 Multi 600/700 M5 B4 mixes method were the more efficient and effective in all categories of asphalt performance measures for strength and durability of HMA as compared to others polymer modifiers. A very good correlation (R 2 = 1) was found for each polymer modifier. This suggested that laboratory test using a various temperatures and loading frequencies can improve pavement mix design, lab and field control and assurance. A strong correlation between binder viscosity and temperature [R 2 = 1] for polymer modified asphalt mixture.Index Terms-Polymer modifier, dynamic modulus, master curve; viscosity, temperature, asphalt mixture, western Australia.
