Subject: Laboratory;Testing for Suitable ·Materials Kaopa Subdivision Storm Water Storage Basin Kailua, Oahu, Hawaii TMK: 4-2-04: 1

Gentlemen:

As requested, we have completed investigation and laboratory

testing for suitable materials to be used in the Kaopa Sub-

division Sto:rm Water Storage Basin project, and the following

e presents the results and conclusions of our testing.

,..

SCOPE OF INVESTIGATION

The "Special Provisions for Kaopa Subdivision Stol"Jllwater

Storage Basin and Outflow Channel" by Mr. Y. Arakaki dated

February 14, 1972 was used as a guide in determining the

acceptability of the materials tested.

Three categories of m~terials a:re called for in the construe-

tion of the earth dam. The first category called "impervious

material;' will be used primarily for the core section of the

dam. The second category called "semipervious material" will

be used in the upstream section of the embankment. The third

-

e

"'

e

Page 2 W.O. 139

category called. "pervious material" will be used in the down-

stream section of the embankment.

Samples for the proposed embankment were gathered.from existing

and proposed subdivisions surrounding'the area. Mater:ials

from four areas were found to be suitable for use in the

construction of the earth dam.

LABORATORY TE.STING

Materials·were tested for their gradational size, maximum

dry dE:msity, Atterburg Limits, and rem<;>lded shear strength

characteristics of internal :friction value and cohes:i,on.

Gradational size was determined by the sieve analysis method,

while the ~aximum dry density was determined in accordance

with the Modified AASHO Test T-180. Laboratory classification ' was determined by the Atterburg Limit Tests according to ASTM

D423 and D424.

Shear tests were performed in the Direct Shear Machine which

is of the strain control type. The rate of de:formation was

approximately 0.03 inches per minute. Each sample is sheared

under varying confining loads in order to determine the Coulomb

shear strength parameters, cohesion and angle of ·internal

friction. Eighty percent of the ultimate value is taken to

determine the shear strength parameters.

CONCLUSIONS ANJ) RECOMMENDATIONS

A. Impervious M~terials

Page 3 W.O. 139

Impervious materials were obtained from Enchanted Lakes

Estates Subdivision Kaopa Unit 3 and from the Dam Site

itself. Materials from each site were mixed together and

tested for their strength characteristics.

We find that it is i1_11possible to have a material with the

gradation given in the special provisions to have a minimum

dry density of 130 pounds per cubic foot. Past experiences

indicate that clays, considered as impervious materials,

generally have a dry density in the range of 90 to 110

pounds per cubic foot.

We there.fore recommend that the special provision$ be revised

to allow for a dry density range of 95 to 105 pounds per

cubic foot. Likewise the Liquid Limit for cohesive clays

generaily are above 50, and we·recommend a raising of the

maximum allowable to 60.

Direct shear tests run on a remolded sample at 90 percent

co1_11paction indicate an internal friction angle of 55° with

a cohesion of 2.28 KSF. Results obtained are above the

minimum requirements as called for in the special provisions.

B. Semipervious Materials

Page 4 W.O. 139

Seu,iperv:i.ous materials were obtained from Kailua He:i.ghts

Unit 1B which is currently being graded, and f-rom Kailua

Heigh,ts Unit 8 which is in the prelim:i,.nary planning stages. I I

Both/materials tested were within gradation limits. The

dry densities ranged between 118.0 and 128.0 pounds per

cubic foot. These values are within the required ranges

as given in the special provisions.

Direct shear tests conducted on remolded samples at 90

percent compaction indicate internal friction angles of

44° and 58° with cohesion values of 2.66 and 1~39 KSF.

c.. Pervious Materials

Pervious materials may be·obtained from the same sites

as the semipervious materials. However to meet gradational

requirements, we recommend that #3.Coarse B select material

having the following gradation be added: to the semipervious

materials in order to be acceptable as pervious materials.

Sieve Size

e,

Page 5 W.O. 139

The #3 Coarse B material can be obtained from rock quarries

of concrete companies.

We recommend that for pervious materials, the dry density

range be between 115 and 125 pounds per clJ,bic foot. This

density requirement will allow sufficient permeability and

dissaption of residual pore pressure while also helping to

support and stabilize the core portion.
