RESEARCH MOTIVATION The bridge piers are highly vulnerable to the impact and blast loads. The position in which they are constructed makes it difficult to install protective devices around them. By the current AASHTO standard, it is possible to under-design bridge piers for commercial vehicle impacts and other events such as blast.
OBJECTIVE To improve impact and blast resilience of bridge piers using polymeric coatings.
CONCLUSION Polymer coating of Portland cement concrete can be achieved with a good bonding. ü The polymeric coating seem to improve impact resilience of Portland cement concrete by increasing absorbed impact energy (i.e., area underneath …

According to the 2013 Report Card for America’s Infrastructure, published by the American Society of Civil Engineers (ASCE), the United States has a bridge rating of C+. The C rating is classified by ASCE as a mediocre standing. Infrastructure that is awarded the C rating shows general signs of deterioration and requires attention.
Our Hypothesis: Smartphones have become readily available to anyone and is a relatively cheap device. They have instruments within them that can capture and collect usable data. An application can be downloaded to record the smartphone’s acceleration. The acceleration data can be used to evaluate vibrations within …
