Case Studies
On Oct. 29, 2012, the storm surge from Hurricane Sandy hit Long Island with a vengeance causing major beach erosion along the island’s south and north shores. One of the regions that received a great amount of damage was the Bayville–Oyster Bay area. West Shore Road, which is the main route between...
The original plan details called for a 15-in.-wide Florida DOT Type II trench drain, and the agency selected the ACO PowerDrain S300K, a 12-in.-wide trench drain system because it met the required hydraulic performance and flow intake capture rates.
Case Studies
The Florida DOT needed to alleviate a drainage issue along a 400-ft stretch of S.R. 555 in Winter Haven, Fla. Given the lack of longitudinal slope approaching an intersection, storm water would collect in low points between S.R. 555 and the driveways to businesses along this stretch of road.    The...
Case Studies
The 20-ft-wide streets of Westlake, Ohio, had centerline and transverse joints every 25 feet that were randomly failing. Due to reflective cracking, concrete streets with asphalt overlays tend to have short service lives—ten years or less—and expensive pavement maintenance afterward. Westlake’s...
DuraPatcher
Case Studies
In the extended winter of 2013-2014, Wright County’s road maintenance crew in central Minnesota, needed all the help they could get to keep their rural routes in good condition. Cold weather keeps the asphalt plants closed in this part of the country, so waiting for a spring that never seemed to...
Redi-Rock Retaining walls
Case Studies
When a bad storm caused a cemetery’s steep slope to erode into the nearby road, the Kentucky Transportation Cabinet needed a solution to prevent further erosion of this sensitive area.   “In May of 2010, we had a flood that caused the land to slide a bit. We had debris in the roadway and it looked...
Contractor protects motorists on U.S. 164
Case Studies
If manhole adjustment is a relatively small part of most paving projects, protecting the raised manhole—after milling and before new paving—is downright obscure.   And ideally, this protection only has to last a day or two. But in some ways, protecting the raised manhole is equivalent to protecting...
Case Studies
The “before” photos of this project are not a pretty sight. A river running below this Washington road had undermined the base of the slope, while runoff had heavily eroded an extremely steep hillside above the road. “Between the hydraulics created by the hill on the back side and the river...
San Diego used the Spectra Roadway Improvement System
Case Studies
The City of San Diego needed to maximize the value of available transportation funds by creating roadways that deliver long service lives with lower construction and maintenance costs. With this in mind, it decided to use the Spectra Roadway Improvement System—a mechanically stabilized layer...
San Diego airport relocates parking lots
Case Studies
The San Diego Regional Airport Authority operates the busiest single-runway commercial airport in the United States. For this project, it sought bids to relocate and expand two employee surface parking lots to a different section of the airport campus.   The challenge The client needed a...
Redi-Rock walls
Case Studies
In 2010, the Mississippi Department of Transportation made plans to widen existing bridges and shoulders on I-59 in Laurel, Miss.   The challenge? “We had a limited amount of right-of-way and we didn’t have time to go buy more. Really what we were trying to do was find a way to limit our footprint...
Storm-water treatment does not effect tight working windows on I-64/I-255 interchange in East St. Louis
Case Studies
In most ways, the resurfacing of the I-64/I-255 interchange near East St. Louis, Ill., was an ordinary—albeit big—project; it’s a large cloverleaf intersection and extremely busy, but paving contractors Keeley & Sons Inc. are used to that. However, there was one unique feature; “Most years, we...
Case Studies

gravity wall problem on Q Street
Case Studies
A host of difficult elements combined to require extreme engineering to solve a gravity wall problem on Q Street between 168th and 180th in Omaha, Neb. This case entailed adding a lane to and widening a stretch of road over a creek, while retaining the existing road’s elevation. It wasn’t a very...
The I-105 Sepulveda Boulevard on-ramp
Case Studies
The I-105 Sepulveda Boulevard on-ramp is the primary egress point from Los Angeles International Airport. The two-lane ramp was notorious for collisions in wet pavement conditions. Collisions on the ramp have been attributed to a tight horizontal curvature, low friction and motorists’ aggressive...

Snap-Tite culvert lining pipe
Case Studies
More than 100 tributaries run through the southwest U.S. and drain into the 1,450-mile-long Colorado River. Corroded metal culverts designed to prevent flooding on roads crisscrossed by those streams are frequently the cause of it. For Colorado county road crews, flooding and washout caused by...
