• Abstract:
  The main objective of this study was to develop thin lift overlay mixtures with polymer modified asphalt for use in New England. As part of this ; research a comprehensive literature review and internet survey was conducted. Moreover, laboratory testing was conducted to develop thin lift Polymer ; Modified Asphalt (PMA) mixtures in an effort to evaluate their use for New England. ; It was attempted to use the Model Mobile Load Simulator (MMLS) to investigate the feasibility of using a non-destructive testing (Potable Seismic ; Property Analyzer) to evaluate the thin lift mixtures. However, after several attempts to compact the asphalt mixtures in the device, achieving target ; density was not attainable. Accordingly this thin lift mixture testing was replaced by dynamic modulus testing in the Asphalt Mixture Performance ; Tester and low temperature cracking using the Indirect Tensile Test (IDT). ; The survey conducted showed the method of selection for either a surface treatment or lift HMA overlay were decision trees, functional classification of ; the roadway, existing pavement condition, experience and treatment cost. Moreover, the majority of respondents did not have a methodology to select ; the appropriate time to apply a strategy. Based on the survey, transportation agencies utilized PMA to reduced cracking, reduce rutting, reduce thermal ; cracking, and extended pavement life. No disadvantages of using polymer modified asphalt were noted. ; Thin lift mixtures were developed with five modified binders and one conventional binder for comparison purposes. The laboratory data indicated that ; the low temperature performance grade of the binders were warmer than the low temperature cracking of the mixtures predicted using IDT ; measurements. This indicates that the use of the PMA did not increase the low temperature susceptibility of the mixtures tested. Therefore, PMA could ; be utilized for thin lift mixtures placed in the New England region.
