Concrete Debris Assessment for Road Construction Activities

The objectives of this project are: (1) Research will be conducted to examine the extent that a pH change will occur in the soil under an RCA base layer (i.e., distance of impact under the RCA). (2) Research will be conducted regarding concrete dust and slurry waste associated with concrete pavement grooving and grinding operations. The high pH associated with the Portland cement concrete (PCC) dust and PCC slurry waste has the potential to adversely impact the surrounding environment. Strategies for the best management practices of this type of concrete waste need to be evaluated. This project will use data gathered through: literature review, a survey of state departments of transportation (DOT's) and the results of experimental testing to suggest best management practices for concrete grooving and grinding wastes.
