Two representative soil samples were returned <br />to our laboratory for analysis of the maximum dry density and optimum moisture content in <br />accordance with ASTM D1557-02 (Modified Proctor). Density test results indicate adequate <br />compaction of at least 95 percent at the tested locations of the building slab backfill. <br />IS<}`� 1_�6°h �' <<i� `�.� �: i��r :i't,l - I3���lc� � ,�, t+� , `E"si}O' o-?5�r 11�7-��(�-1 � i�`i7 . � �, .� y t�11 <br />
