Paper Title:
Study on Simplified Test Method about Fatigue Performance of Cold Patch Asphalt Mixtures
  Abstract

The objective of this investigation was to develop a test methodology to assess the fatigue performance of cold patch asphalt mixtures, potentially usable in the field as a quality control method.The methodology was developed by identifying the relationships between the parameters from a Laboratory Fatigue Test (IDT,according to ASTM D4123 ), and the penetration rate (NPR) from a lighter version of the Dynamic Cone Penetrometer (DCP) at various densification levels. Multiple linear regression analysis (MLRA) was used to develop equations to estimate number of load cycles to fatigue, and critical tensile strain. The fatigue equations were satisfactorily validated after comparing the measure stability parameters from two mixtures not used in the regression analysis. Cross-validation using SPSS procedure was also implemented.
