When it comes to building roads in America, you have to be able to use current and past data to determine the future traffic at least 40 years out. In an attempt to get the most of every tax dollar the bridges and roadways are expected to last even longer than 40 years. Product innovations in sealers and bonding agents are making it possible to seal bridges to protect them from the acidic action caused by the salt and other agents used to make winter travel possible. If you can make the bridges last over 100 years other questions play into the future vision. What will the buildings and architecture around the bridges look like? What do we want them to look like? By changing the aesthetics now can you push the society to become more beautiful? Would this stimulate more investment to achieve these heights of future American pride? Does this aesthetic attempt affect future tourism dollars spent in a location? These are all factors and topics of architects and penny pinching tax payers when investing in our infrastructure.
Meanwhile in Wisconsin, federal stimulus dollars are building roads and much needed bridges. A common question is heard in discussions in the workplace lunch rooms to coffee houses, does the bridges and the roads have to be so fancy?
The new cement techniques in stamping and coloring techniques used in today's concrete can be and are used in bridge building. They are then sealed to protect from the salt and other winter road slip inhibitors that shorten bridge life. Here are some great technique videos that show some of this new amazing technology.
