National Road Research Alliance: Permeability of Base Aggregate and Sand

The National Road Research Alliance (NRRA) is a pooled fund that will help direct and compliment the use of the MnROAD test track for local, regional and national research, tech transfer and implementation needs. This project will quantitatively assess permeability of a wide range of course materials from base course (2" minus) to sand size (less than 20% finer than sieve #200) for design. Laboratory permeability tests will be conducted on aggregates of different types, gradations, angularity, fine contents, and crushing percentages. The test results will be analyzed using statistical methods to develop a simple predictive tool that may be used to assess permeability from gradation, crushing percentage, fines content, aggregate angularity, and material type.
