Classifications for the subgrade materials, including Atterberg Limits, all in
accordance with ASTM or AASHTO criteria.
b. Evaluation of Findings
STANTEC will conduct AASHTO pavement designs for the alternatives considered.
Recommended alternatives will be evaluated based on considerations of life-cycle
cost, maintenance, and rehabilitation or reconstruction options for each pavement
area, for a proposed twenty-year period. A technical Pavement Engineering report
will document the investigation, evaluation and recommendations for each
pavement section designated within project area.
Project-Level Evaluation/Pavement Design Task:
a) Test Pit (Equipment, operator, police detail
and traffic control to be provided by DPW) $750 each
b) 6” Pavement Core $175 each
c) Pavement Engineer $128/ hour
This task is intended for street segments where the City expects a high-level investment of
paving dollars and costly pavement markings, i.e. arterial and collector roadways.
PAVEMENT MATERIAL QUALITY ASSURANCE TESTING:
STANTEC will provide a field inspector/engineer to provide oversight of quality of materials
used this construction season. The inspector will monitor the placement of the hot mix
asphalt (HMA) materials and to check quantity of materials on a daily basis. The inspector
can be made available both in the field and at the plant.
In the field, temperatures of the materials, as placed, will be documented along with the
nominal compacted thickness. The base temperature and condition will be monitored, tack
coat, etc., will be reported. A report indicating material type, quantity, mix temperature,
and equipment condition will be provided.
At the HMA production plant, STANTEC will sample random points from the proposed day’s
production, from which an extraction/gradation test shall be performed to ensure mixture
specified per contractor's job mix formula (JMF). Theoretical maximum specific gravity will
