摘要

The report presents the results of a laboratory study to evaluate the effectiveness of two proprietary materials, Paczyme and Reynolds Road Packer, for improving the compactability and strength of fine-grained soils. The testing program was conducted on four fine-grained soils of three different clay mineralogies typical of those found in the mid-Atlantic States. The effects of Paczyme and Road Packer on (1) Atterberg limits; (2) the optimum moisture content and maximum dry density as determined by AASHTO Methods T 99 and T 180; (3) unconfined and triaxial compressive strength; (4) California Bearing Ratio (CBR); and (5) resistance R-Value and expansion pressure, were determined. Based on the results of the testing program it was concluded that neither Paczyme nor Road Packer produced sufficient alteration of soil properties to be of any practical utility.
