Pedestrian Walkway Location – Alternative Design #2

Before the actual design of the pedestrian bridge can be determined, the most fitting location must be chosen. By exploring this second option as a location for the walkway as seen in the Google Maps satellite image attached , the design constraints change drastically. Factors such as the elevation on each side of the road, the length across Route 29 from point A to point B change and the angle, sloping and positioning of the skyway change drastically as shown in the attached NJDOT roadway cross-section. This alternative location provides a potentially stronger and more effective connection between the local neighborhood and Waterfront Park area and new trail. The new location connects the South tip of Cooper field and merges into the trail both Northward and Southward. The location is more central and taps into a new community.

Concrete Polymer

Teammate, Elias Bermudez, received contact from the New Jersey Department of Transportation. These is the standard requirements that high performance concrete must be meet. The four polymer concretes that will be tested against HPC and the specifications listed below are:
Epoxy and Vinyl Ester concrete will be provided by Sauereisen. The Polyester concrete will be provided by Kwik Bond. Methyl Methacrylate will be provided by Transpo Industries Inc.

Note: For this table HPC-1 are the requirements for bridge decks, so those 4 tests (ASTMC672, ASTMC666, AASHTOT277, and ASHTOT22) are the four that Elias is looking to conduct.
