Abatech has extensive experience in the testing and design of
pavements for ports and intermodal facilities. Our staff have
been involved with various large scale projects such as the Port
of Felixstow in Suffolk, England (which at that time was the
largest block paving project used for a port application) and the
pavements in the Port Authority of New York and New Jersey
(Elizabeth Terminal and others), since the late 1980s. Since 1997
when Abatech was formed the company has been continually involved
with port pavements and intermodal facilities.
Abatech has
customized software that specifically considers the interaction of
soil-structure problems, including FE analysis, with very heavy
loads. Soils can be modeled as stress dependent or cross
anisotropic. This helps to allows a full understanding of
heavy loads on ports and industrial pavements. Soil models
also include different failure criteria based upon various stress
states.
A list of typical projects is provided, as follows: |
Falling Weight Deflectometer testing in ports provides
valuable information of structural properties of pavement layers

- Port
of Vancouver, British Columbia, Canada (1999). Design of modified
asphalt pavement for heavy loading on behalf of supplier of modified
asphalt materials with a value engineering proposal for use of novel
materials.
- South
Intermodal Yard, Port of Tacoma, Washington (1999). Development of
value engineering proposal for alternate pavements at the Port of
Miami, Florida.
- Port
of Miami, Florida (1999). Development of value engineering proposal
for alternate pavements at the Port of Miami, Florida.
-
Chalmette Terminal - Kaiser Site, Port of New Orleans, Louisiana 1999.
Assistance to modified asphalt producer with developing pavement
designs for the Port of New Orleans.
- Port
of Tacoma, Washington, 2000. A detailed pavement design for the South
Intermodal Yard, Port of Tacoma, WA. The pavement at this facility is
to undergo a major rehabilitation due to premature failure of the
existing concrete pavement structure. Detailed structural design was
carried out with modified bituminous materials. The pavement
construction for these areas utilized Roller Compacted Concrete (RCC)
which is 17-inches thick adjacent to the rail tracks and 12-inches
thick for the central roadway. The RCC is placed upon a 4-inch layer
of compacted subgrade for all locations.
- CSX
Intermodal Facility, North Bergen, New Jersey (June 2002). Pavement
Evaluation and Design Review Bergen Intermodal Facility which involved
the evaluation and design of pavements for intermodal facility using
FWD and Dynamic Cone Penetrometer testing which involved the
rehabilitation of network of existing pavements in an intermodal
(road-rail) facility in northern New Jersey. The pavement evaluation
considered of Falling Weight Deflectometer, Dynamic Cone Penetrometer,
Coring and Soil Borings. Laboratory work on the soils and other
materials included full classification to a depth of approximately
30-feet in order that weak underlying soils could be evaluated. The
pavement design was conducted using analytical design methods
(KENLAYER). Stiffness information for materials was developed using
material and climatic effects models. Pavement design needed special
consideration due to the heavy loads being applied to the pavement
structure by the unloading/loading equipment at the facility.
- Port
of Baltimore (2001 to 2009). Evaluation of pavements at Dundalk
Terminal for long-term pavement management program. Project included
visual survey, pavement management database, FWD testing, stress
analysis. The entire set of data and performance was linked into a GIS
representation of the port pavement.
-
Terminal 18, Harbor Island, Seattle 2003. Design of modified asphalt
pavement for heavy loading on behalf of supplier of modified asphalt
materials with a value engineering proposal for use of novel
materials. This site was constructed and used a soil staging area for
port degrading operation for a two year period with installation of
rail tracks for hauling contaminated materials to a safe disposal
facility.
- Maersk
Terminal, Port Elizabeth, New Jersey (2003 to 2004). Assessment of
port pavements with Falling Weight Deflectometer over a one year
period to study the variation of soil stiffness and pavement
properties with the season to further develop the pavement design
methods for the PANYNJ.
-
Burlington Northern SantaFe Railroad Intermodal Yard, Stockton (1999).
California Design of pavement structure for intermodal facility in
California involving assessment of PCC, lime treated soil and TLA
modified asphalts. In particular the use of thick "sandwich" pavement
construction was investigated for this project.
- Pierce
County Terminal, Port of Tacoma, 2007. Design advice to Wilder
Construction company and presentation to port regarding different
design build options for pavement structures to improve the life cycle
cost of poorly performing pavements.
-
Rybovich Yacht Services, West Palm Beach, Florida (2007 to 2008).
Assessment of asphalt concrete pavement in port facility being used
with large boat lifts (luxury yachts) with loads up to 300,000 lbs in
West Palm Beach, Florida. Project includes Finite Element analysis
considering plastic failure in both soil structure and asphalt
materials in hot climatic conditions and at slow speeds of loading.
Analysis also performed in accordance with Asphalt Institute method
for design of port pavements with heavy loads.
- Area
1800, Port of Baltimore. 2007 to 2009. Construction supervision of
pavements for Area 1800 of Dundalk Marine Terminal reporting to
CH2MHill and preparation of data in suitable format to support
warranty obligations of contractor.
- Port
of Baltimore, Area 1800, Dundalk Terminal (March 2009). Visual survey
of area 1800 with three trial pavement areas consisting of one with
articulating concrete blocks, and two polymer modified asphalt
sections.
