Development of a Test Level 3 Transition Between Guardrail and Portable Concrete Barriers
Road construction often requires that work zones be created and shielded by portable concrete barriers (PCBs) to protect workers and equipment from errant vehicles as well as to prevent motorists from … [Read more...] about Development of a Test Level 3 Transition Between Guardrail and Portable Concrete Barriers
Testing and Evaluation of MASH TL-3 Transition Between Guardrail and Portable Concrete Barriers
Three full-scale vehicle crash tests were conducted according to the Manual for Assessing Safety Hardware (MASH) Test Level 3 (TL- 3) safety performance criteria on a transition between the Midwest … [Read more...] about Testing and Evaluation of MASH TL-3 Transition Between Guardrail and Portable Concrete Barriers
Length of Need and Minimum System Length for F-Shape Portable Concrete Barrier
Portable concrete barrier (PCB) systems are often used to redirect errant vehicles through a combination of inertial resistance, lateral friction loads, and tensile loads developed from the mass and … [Read more...] about Length of Need and Minimum System Length for F-Shape Portable Concrete Barrier
Development of a MASH TL-3 Transition Between Guardrail and Portable Concrete Barriers
Often, road construction causes the need to create a work zone. In these scenarios, portable concrete barriers (PCBs) are typically installed to shield workers and equipment from errant vehicles as … [Read more...] about Development of a MASH TL-3 Transition Between Guardrail and Portable Concrete Barriers
MASH Evaluation of TxDOT High-Mounting-Height Temporary Work Zone Sign Support System
The objective of this research was to develop a nonproprietary, lightweight, crashworthy, temporary work-zone single sign support for use with an aluminum sign substrate. The device is intended to … [Read more...] about MASH Evaluation of TxDOT High-Mounting-Height Temporary Work Zone Sign Support System
