Dept. of Transportation. Bureau of Materials and Physical ResearchUnited States. Federal Highway AdministrationUS Transportation CollectionA series of five experimental projects were constructed to better determine the life-cycle cost and performance of pavement overlays using various types and combinations of recycled materials\u2014namely, reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS) and crushed concrete. The asphalt binder replacement (ABR) varied from 15% to 48% in the experimental sections. The study of these projects prior to construction, during construction, and for a short monitoring period after construction is intended to determine the impact of various pavement conditions, pavement cross-sections, mix designs, and material properties on the ultimate performance of the hot-mix asphalt (HMA) overlay. This interim report documents the construction and testing to date on two of the five projects in the study\u2014Crawford Avenue/Pulaski Road and US 52 (IL 52 to Laraway Road)\u2014that were constructed in 2014. Distress and profile surveys were conducted before and after construction. Samples were obtained of the HMA surface and binder courses and were tested for basic properties, plus Cantabro, stability/flow, Texas overlay cracking potential, fracture energy, flexibility index, fatigue, modulus, creep, and Hamburg rutting. Presented are early performance trends and baseline conditions that future performance can be compared against. Also included in this report is an update of performance on three total recycle asphalt (TRA) sections and a comparison section constructed in 2013 with ABR\u2019s ranging from 20% to 60%75
