Mr. Elliott,
CITY OF COLLEGE STATION
The one year time period on the Maintenance Bond related to the overlay of
Renee Lane adjacent to Needham Estates Subdivision is expiring January 24 ,
2009. The City as well as CME Testing and Engineering, Inc. has conducted an
inspection of your associated 1.5 inch HMAC overlay on Renee Lane and has
found some portions of the overlay are deteriorating. As to avoid using the
aforementioned Maintenance Bond (attached for your reference) the City would
request that you perform a 2 foot edge repair on both sides of Renee Lane to
include a full depth milling, replacement of hot mix and a complete one coarse
seal coat on the portion of Renee Lane adjacent to the Needham Estate
Subdivision. Please let our engineering inspector, Keith Tinker (777-0292) know
prior to beginn ing the repair.
Sincerely,
z~

Re: Report of Pavement Investigation (Coring and Soil Testing)
Needham Estates Re-Plat; College Station, Texas
Dear Mr. Young:
CME Testing and Engineering, Inc. (CME) is pleased to submit this letter report of the results of our
investigation of the existing pavement system in the roadway areas of Renee Lane located in the
Needham Estates Re-Platted Subdivision in College Station, Texas. The Needham Estates Re-Platted
Subdivision is situated southwest of the intersection of Victoria Avenue and Barron Road.
Project Description and Purpose of Investigation
We understand that the several improvements have been made to the Needham Estates Replatted
Subdivision. Those improvements are outlined in the drawings prepared by McClure & Browne
Engineering/Surveying, Inc. which had an original date of September 2007 and various revision dates
extending to November 2, 2007, along with a City of College Station Reviewed for Compliance stamped
date of November 6, 2007.
The plans included proposed improvements to the existing Renee Lane pavement section. Those
improvements were outlined in Note 13 on Sheet 2 of the referenced drawings and can be summarized as
follows:
13. Approximately 1200 SY of Renee Lane to be overlaid with 1.5" HMAC following
utility construdion. Preparation of the swface shall be in accordance with Spec. #335.
Overlay construction methods and material shall be in accordance with Spec. #330. A
Lack coat in accordance with #326 shall be applied prior Lo the overlay. All pot holes
shall be saw-cut, baclifilled with base material, and compacted prior to overalay.
The purposes of our investigation were to determine the thickness of the overlay layer in conformance
with the previously referenced plan requirements for Reene Lane, as well as the different types and
thicknesses of the material layers comprising the pavement system and the nature of the subgrade soils
and foundation soils underlying the pavement section.
To accomplish these purposes we conducted both a field investigation and a laboratory testing program as
described in the following sections of this report.
CME TESTING AND ENGINEERING I INC.
Report of Paving Investigation for Renee Lane
Needham Estates Re-Plat; College Station, Texas
Field Investigation
The field investigation was performed on January 16, 2008 and consisted of initia11y coring the existing
pavement at the three locations indicated on the attached figure. Four inch diameter cores of the surface
coarse layer of hot mix asphaltic concrete (HMAC) were obtained and taken to the laboratory. The
surface of the base course layer underlying the HMAC surface course was also observed following coring
of the HMAC layer to determine if there were indications of a seal coat and/or a tack coat between the
HMAC layer and the base course layer.
The underlying base course consisting of crushed rock was then cored or hand augered to determine the
apparent thickness of base course layer.
The thickness of the HMAC surface course layer and the base course layer were measured at each
core/bore hole location.
Finally, disturbed samples of the underlying subgrade soils that ex.tend from below the base course layer
to a depth of approximately 6 inches were obtained by hand augering as were the foundation soils that
ex.tended from approximately 6 inches to 12 inches depth below the bottom of the base course layer.
The soils samples were removed from the auger and visually classified in the field. The disturbed samples
of subgrade soils were packaged in plastic bags and taken to the laboratory for classification testing.
Laboratory Testing Program
The classification tests were performed in order to classify the subgra.de soils in accordance with the
Unified Soil Classification System (ASTM D 2487). The classification tests included the liquid limit (LL)
and the plastic limit (PL) of the soils. The LL and the PL are often collectively referred to as the Atterberg
limits. These limits distinguish the boundaries of the several consistency states of plastic soils. The LL
represents the moisture content at which the soil is on the verge of being a viscous fluid (i.e., a "very wet"
condition), and the PL represents the moisture content at which the soil behaves as a non-plastic material
(i.e., a "slightly moist" condition). The plasticity index (Pl) of soil is defined as the range of moisture
contents at which the soil behaves as a plastic material and is described as the difference between the
liquid limit and the plastic limit (LL -PL= PI). The magnitude of the PI of a soil is typically considered
to be an indication of the clay content and the volumetric change (shrink-swell) potential of the soils
(although the volumetric change can also vary with the type of clay mineral and the nature of the ions
adsorbed on the clay surface). Soils possessing high values of PI are said to be "highly plastic" or "fat"
and those with low values are described as "slightly plastic" or "lean." Pure granular materials, such as
sands or gravels, are typically nonplastic and have a PI value of 0. The Atterberg limit determinations
were performed in general accordance with the procedures outlined in ASTM D 4318.
In addition to the selected Atterberg limit tests, grain-size distribution tests were also performed. TI1e
percent of soil particles passing the U.S. Standard sieve size No. 200 (ASTM D 1140) was determined.
The soil fractions passing the No. 200 sieve size are the silt-and clay-size particles and are generally
referred to as "fines."

CME TESTING AND ENGINEERING. INC.
Report of Paving Investigation for Renee Lane
Needham Estates Re-Plat; College Station, Texas
The subgrade soils were also tested for the presence of a hydrated lime stabilizing agent by adding the
chemical known as phenolphthalein to the soils. Phenolphthalein is a chemical that is typically clear or
colorless but will tum purple in the presence of lime.
The soil and pavement samples will be stored for at least 30 days following the date of this report. At the
end of the 30-day storage period, the samples will be discarded unless written communication is received
from the owner requesting that the samples be stored for a longer period.
Presentation of Results
The results of the field measurements and the laboratory classification tests are summarized in Table I.
The total thicknesses of the HMAC surface course measured at the three (3) core/boring locations ranged
from 1.6 inches to 4.75 inches and exceeded the specified minimum overlay thickness of 1.5 inches. The
thicknesses of the crushed rock base course layer varied from 1.0 to 3.0 inches at the three (3) core/boring
locations. The apparent presence of a seal or tack coat between the surface course layer and the base
course layer was observed at two (2) of the three (3) core/boring locations.
The subgrade soils generally consisted of brown, clayey sands, with some gravel. The phenolphthalein
tests did not indicate the presence ofa lime stabilizing agent in any of the subgrade soil samples. The
subgrade soils exhibited percent fines ranging from 27.9 to 47.9 percent and plasticity index values
ranging from 18 to 25. The foundation soils below the 6 inches of subgrade soils were similar to the
subgrade soils and generally consisted of brown to tan, clayey sands or silty, clayey sands with percent
fines ranging from 34.2 to 42.2 percent and PI values of between 6 and 14.
We sincerely appreciate the opportunity to have performed this investigation. Please do not hesitate to
contact us should you require any additional information or if we may be of further assistance.
