Performance of New-Generation Portable Water-Filled Road Safety Barriers Under Vehicular Impact
Portable water-filled barriers (PWFB) are roadside structures used to enhance safety at roadside work-zones. Ideally, a PWFB system is expected to protect persons and objects behind it and redirect … [Read more...] about Performance of New-Generation Portable Water-Filled Road Safety Barriers Under Vehicular Impact
Impact and Energy Absorption of Portable Water-Filled Road Safety Barrier System Fitted with Foam
Portable water-filled barriers (PWFBs) are roadside appurtenances that are used to prevent errant vehicles from penetrating into temporary construction zones on roadways. A numerical model of the … [Read more...] about Impact and Energy Absorption of Portable Water-Filled Road Safety Barrier System Fitted with Foam
Pinned-Down Temporary Concrete Barrier With Transition Systems for Limited-Space Work Zone Applications
In work zones where space for placing temporary concrete barrier is very limited (such as bridge expansion or repair), the barrier must be restrained to prevent large lateral deflection due to vehicle … [Read more...] about Pinned-Down Temporary Concrete Barrier With Transition Systems for Limited-Space Work Zone Applications
