Gentlemen:
Submitted here are the results of testing and observation of
construction materials at the referenced project. This report
addresses activities for the period of October 24 through 27, 1995.
On October 24, 1995, five field gradation tests were performed on the
soil-lime mixture. Test results are summarized on Plate 1. Where
tested, materials were found to be in compliance with project
specifications.
In addition, a sample of the soil-lime mixture was obtained and
returned to the laboratory for development of an optimum moisture-
density relationship (Standard Proctor Curve). Test results are
attached as Plate 2.
On October 27, 1995, three field density tests were taken on the
lime-treated paving subgrade. Test results are shown on Plate 3.
Where tested, materials were found to be in compliance with project
specifications.
