RE: Lime Series Test Results
Proposed "Trinity Shore Estates"
Sandy Lake Road
Coppell, Texas
Gets rlemen:
On August 14, 2002, one soil sample was obtained from the exposed surface area of the graded
street sit the location of the above referenced project. In accordanr.c with your authorization, a 1..imc
Series testing procT am was performed on the sample obtained. The results of the Lime Series Test
are as follows:

I,abol story testing results indicate that optimum lime additive contents For the purpose of soil
stabilization for tale above referenced project is 12 percent of the dry weight of the soil. however,
Gmcie?ux recommends 14 percent lime be added to stabilize subgrade material at a minimum
application rate of approximately 56 pounds of hydrated lime per square yard for the 6 inch

on the No. 4 sieve arc removed, the remainder of the material meets the following requirements
when tested dry by laboratory sieves:
• Minimum passing 1 -3/4" sieve — 100
• Minimum passing No. 4 sieve — 60%
During the interval of time between application and mixing, the liydrtted lime should not be
exposed to the open air for a period of over six hours.
Compaction
Compaction of the mixture should begirt immediately after final mixing and in no case later than
three calendar days after final mixing. The material should he aerated or sprinkled ats necessary to
provide the optimum moisture. Compaction should begin at the bottom and continue. until the
entire depth of mucture is uniFortnly compacted. All irregularities, depressions, or weak spots which
develop must be corrected immediately by scarifying the areas affected, adding or removing material,
and reshaping and re- compacting by sprinkling and rolling. The surfilce should be maintained in a
smooth condition — free From undulations and ruts.
The modified subgrade should he compacted to a minimum of 95 percent of Standard Proctor
density (ASTM D 698), it a moisture ronrent within 3 percentage points of optimum moisture
content. Compaction and moisture checks should be taken within all paving areas it the rate of one
field density test per every 200 linear feet of road. These rests are necessary to determine if the
recommended moisture and compaction requirernenrs have been attained. After required
compaction is reached, the subgrade should be brought to the required lines and grades and finixhed
by rolling with a pneumatic tire or other suitable rollers sufficiently light to prevent hair cracking.
