City of Houston
Pavement Management System
We inventoried and surveyed over 6,000 centerline miles of streets for the city's Pavement Maintenance Management Program. Surveys included curbs and gutters, shoulders, roadside ditches, railroad crossings, pavement striping, and bridges. We developed computer software to rate pavement condition and select rehabilitation strategies.

Austin-Bergstrom
International Airport, Austin
HVJ provided engineering services to the City of Austin for the conversion of the former U.S. Air Force base into city's new international airport. New pavements were designed following FAA guidelines for airside pavement, which includes runways, taxiways, and aprons. AASHTO guidelines were used for landside pavements-roadways and parking lots. Finally, we implemented MicroPAVER©, pavement management software developed by the U.S. Army Corps of Engineers to assist airports in monitoring pavement conditions and optimizing the use of repair funds.

City
of Austin Reconstruction program
HVJ performed pavement evaluation, deflection testing,
and rehabilitation designs for over a dozen streets. Our
designs included construction plans and costs for asphalt
mill and overlay, asphalt pavement reconstruction, concrete
bus lanes and pads, sidewalks, driveways, ramp improvements,
traffic control, striping, and temporary environmental
controls during construction. HVJ provided construction
phase consulting.

Easterwood
Airport, College Station, Texas
We surveyed the condition of all airside pavements to help Easterwood implement the MicroPAVER© software system. We collected thickness and strength data and conducted deflection testing to determine Pavement Classification Numbers for estimating allowable aircraft loads.

City of
Brady Street Improvement Project
Brady is a town of about 6,000 people in the geographic center of Texas. The city government wanted to implement street improvements based on the MicroPAVER© system. We inventoried and surveyed all of Brady's streets. We also developed construction documents to Texas Department of Transportation standard specifications and assisted with the bidding process. Construction phase consulting was also provided.

Travis
County Pavement Management System
HVJ surveyed the entire 1,140-mile roadway system of Travis
County, home of the state capitol. We conducted
a visual condition examination to help implement MicroPAVER©
system for the county. We worked closely with
the county's Transportation and Natural Resources staff
to develop a 2002 work plan. Road sections were selected
for reconstruction, rehabilitation, overlay, or sealing.

Bayport
Backlands Expansion
Falling Weight Deflectometer (FWD) measurements were collected and analyzed to develop subgrade strength values for the design of pavement for a new state-of-the-art container terminal at the Port of Houston. A full scale test pad was constructed using standard construction methods and FWD deflections were measured at varying loads to determine the effects of heavy front and side lift trucks, straddle carriers, yard gantry cranes, and tractor trailer systems on the subgrade soils.
