Determining the Relative Importance of Parameters Affecting Concrete Pavement Thickness
Spending costs in construction of road pavements has turned this subject into one of the significant points in transportation infrastructure of countries. Concrete slabs consider as a paving method with ability of reducing the rehabilitation needs. Therefore, to manage costs and optimize the thickness of concrete pavements, recognizing the amount of determinative factors’ influence will be requ...
متن کاملAn apparatus and a method for determining the slip resistance of shoes and floors by simulation of human foot motions.
An apparatus to measure the coefficient of kinetic friction (mu k) between the shoe sole and the underfoot surface was constructed, and a method including criteria to evaluate the risk of slipping during walking was developed. The apparatus is a prototype stationary step simulator capable of simulating the movements of a human foot and the forces applied to the underfoot surface during an actua...

متن کاملinvestigating 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...
A Portable HPGe System for Measuring Contaminated Soils and Floors
Decontamination and decommissioning (D & D) requires the characterization of large surface areas such as soils, walls, and floors. To address the identification and quantification of radioactive material in these problematic surroundings, a portable high-resolution gamma-spectrometry system has been developed. The system was tested using the calibrated concrete slabs at Grand Junction, Colorado...
