Abstract:This project developed and evaluated four new asphalt concrete (AC) mixtures that use locally available aggregates whenever possible with the ultimate goal of a cost-effective mixture that also improves pavement performance. Although numerous tactics have previously been introduced to improve the performance of asphalt pavement, these improvements often add expenses because they use unnecessarily large amounts of high quality aggregates and highly modified binder. The Illinois Department of Transportation initiated a program to develop sustainable asphalt pavements that use locally available aggregates as much as possible to reduce the material cost while also improving performance. These new mixtures were developed using the Bailey method to provide a promising aggregate structure that makes it possible to ensure compactability at thinner layers. The newly developed mixes use locally available natural aggregates such as dolomite, and including smaller amounts of imported materials such as quartzite, steel slag, and fibers to improve their performance in terms of durability, rut resistance, moisture susceptibility, fracture, and complex modulus. To evaluate the performance of each new mixture, five laboratory tests were conducted at the Advanced Transportation and Research Engineering Laboratory (ATREL), and the results suggest a preferred mixture.
