    Abstract

    Cold recycling is a technically promising and cost effective method for improving distressed asphalt pavements. Unlike hot-mix recycling, cold recycling lacks extensive field and laboratory performance data. There is no widely accepted cold in-place recycling (CIR) mix design and testing standard available. This study attempts to generate useful field and laboratory data on pavements constructed with CIR mix and technique. Two field case studies are conducted. The testing of field cores and laboratory samples from these two field sites is conducted to address the existing and new methods for design and performance testing of CIR mixes in partial depth pavements. The laboratory tests include physical property testing (e.g., moisture content, gradation, air voids, emulsion, and aggregate properties) and performance-related testing (e.g., resistance to deformation, retained strength, rut, and fatigue). Relative performances of the CIR mixes from the two sites are analyzed.
