Evaluation of Hot-Mix Asphalt Sampling Techniques

Insuring the integrity of hot mix samples is critical to assuring the quality of the completed product and complying with Federal requirements. Samples of asphalt mixture are currently taken at the hot mix plant without state supervision. Further, samples are taken from a truck where obtaining a representative sample can be difficult and easily subject to bias. The concept of moving the sample location to the job site offers the potential to address the weakness cited above. However, there are a number of different approaches, each with advantages and disadvantages. Research is needed to survey practice and arrange visits with practitioners in Illinois and other states.
