PERCENT
Minimum Passing 1" Sieve 100
Minimum Passing No. 4 Sieve 60
b. Old bituminous wearing surface shall be pulverized so that 100% will
pass a 2" sieve.
c. During the interval of time between applications and mixing, hydrated
lime that has been exposed to the open air for a period of 6 hours or
more or to excessive loss due to washing or blowing will not be
accepted for payment.
3.07 COMPACTION:
A. Compaction shall be in layers (6" maximum-loose measure) to the uniform density as
shown on the drawings.
B. Compaction of the mixture shall begin immediately after final mixing and in no case later
than 3 calendar days after final mixing, unless approval is obtained from the Engineer.
C. The material shall be aerated or sprinkled as necessary to provide the optimum moisture.
D. Compaction shall begin at the bottom ad shall continue until the entire depth of mixture is
uniformly compacted as hereinafter specified.
E. If the total thickness of the material to be treated cannot be mixed in one operation, the
previously mixed material shall be bladed to a windrow just beyond the area to be treated
and the next layer mixed with lime as previously specified. The first layer of the treated
material shall be compacted in such a manner that the treated material will not be mixed
with the underlying material.
F. After compaction and shaping the surface shall be kept wet until the paving is applied to
seal the sub grade.
3.08 ALLOWABLE TOLERANCES:
A. SURFACE TEST:
1. After the sub grade is completely compacted to required density, the surface
shall be tested for smoothness and accuracy of grade as hereinabove set out. If
any portions are found to lack required smoothness or failing accuracy of grade
or crown, such portions shall be scarified, reshaped, recompacted and otherwise
manipulated until the required smoothness and accuracy is obtained. The
Contractor under the supervision of the Engineer shall make these tests.
2. Density: Field density tests will be taken in accordance with the provisions as set
out in Section 01400 Quality Requirements.
