Subject: Thick Lift Pavement Design `Avenida'Obregon
{ k. . .
As requested, wehave reviewed the preliminary pavement design section along with the results of
`previous'R-Value testing in order to provide a'"thick lift" asphalt section for use alongAvenida .
Obregon within the La Quinta'Resort &"Club complex'in La Quinta;' California.; It is. our
-
; understanding that thick lift asphalt pavement is preferred in lieu of -the previously approved
pavement section (3.0" asphalt on 4.5 ." base) due to project time'constraints. ` -
r
i
r Y
Previous testing the La,Quinta Resort & Club indicated R-Values.varying from 45
within complex
+to over 60.. Based upon -the previous testing and' our recent site observations,' it is "our •opinion-
that. a design R-Value of 50 is appropriate for use in thick lift 'asphalt pavement design.
Based upon a design' R-Value of '50 and an expected Traffic Index of approximately 5.5,.a thick
'
= .lift section of 4.5 -inches of asphalt on compacted native=subgrade soils should .be''•adeguate:
However,: -considering the, expected construction' traffic and KSL's desire 'r to provide. "a
-
conservative design in'this case, it is our opinion that theahick lift pavement section shouldbe'
increased accordingly. We recommend a thick lift pavement section of 6:0 inches of asphalt
r
on compacted, native 'subgra ' soils. The proposed hick lift pavement section correspondsAl '
Y'
with a traffic index of approximately 7.0. `
Pavement should be confined by curbs. Subgrade should be compacted to at least 95 % relative
`
compaction. Subgrade should remain firm and unyielding. Compaction' should be verified by . .
s =testing. `
