Identification: Atterbers' Limits Test of Lime Treated Subgrade Soils
Method of Test: ASTM D4318
On December 4, 2015 a representative of GEE Consultants, Inc. collected subgrade soil samples
from pavement area located between station 2+37 and 14+60. The purpose of soil sampling was
to perform Atterbergs' Limits tests on previously lime treated soils and check if long exposure of
subgrade soils under recent rainfalls has affected the lime stabilization.
The test results are as follows. ,
