Abstract:

This project provides techniques to improve hot-mix asphalt (HMA) overlays specifically through the use of

special additives and innovative surfacing technologies with aggregates that are locally available in Illinois. The

ultimate goal is to improve pavement performance through optimized materials while also controlling cost by

efficiently using local materials. Therefore, the proposed new mixes use locally available aggregates when

possible. The project also considered the use of alternative aggregates such as steel slag to increase the

friction quality of the HMA and therefore improve pavement performance. To evaluate the newly developed

wearing course mixtures and evaluate their performance under actual traffic loading, test pavements were

constructed, including control mixtures, between August and November 2010 in northern Illinois. The newly

proposed mixtures include fine dense-graded HMA and stone matrix asphalt (SMA). The fine dense-graded

HMA was designed using the Bailey method and developed with the hope of improved compactability for thinner

asphalt layers. The SMA contained a 4.75-mm nominal maximum aggregate size (NMAS) that allows for layers

as thin as 0.75 in. On-site performance tests were conducted at 4-month intervals following construction; the

tests include noise, friction, rutting, and texture profiling. An engineering benefit analysis was performed to

evaluate the new mixes’ cost effectiveness. New HMAs are proposed, along with alternative cross-sections that

improve pavement performance while controlling costs.
