Application Of Polyurethane Products In Accelerated Construction Of Innovative Noise Barrier, Bahman Daee

Electronic Thesis and Dissertation Repository

Noise barriers (sound walls) are usually constructed along roadways to mitigate the airborne noise emanating from vehicles. They are currently built using various materials including precast concrete panels, masonry, wood and transparent sheets. The main challenge in roadside construction is the obstruction of roadways during the construction, which may result in traffic congestion, public dissatisfaction, car collision and subsequently fatalities. In order to decrease the risk of roadside construction, accelerated and non-obstructive methods are highly preferred by transportation authorities.

An innovative wall system comprised of polyurethane products is proposed, developed and investigated for application in accelerated construction of noise barriers. …
