Design Tool for Controlling Runoff and Sediment from Highway Construction

Regulations require that stormwater pollution prevention plans be developed for construction activities that disturb an area that is equal to or greater than one acre. Different strategies, including a combination of practices, can be used to develop these plans. The WATER model was a tool developed from a previous project to assess the effectiveness of different on-site sediment control practi...

Contracting Methods for Highway Construction

Transportation construction is a large industry—particularly highway construction, on which more than $50 billion is spent annually. Small improvements can result in significant savings in time and cost, as well as better quality and fewer disputes. In recent years, many innovations have occurred in highway construction. The atmosphere within the industry is highly charged with optimism, uncert...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
