Sand barrels in work zones

Oregon’s Traffic Drawings TM 800 Series – Temp Traffic Control (See Temporary Impact Attenuators) contain the necessary information concerning the use of sand barrels in work zones. From the drawings, information pertaining to the number of drums required and the quantity of sand required for each drum (in pounds) can be found based on the preconstruction posted speed of the highway. See Oregon’s Qualified Products List (QPL) web site below for further details (search by ‘Product Category’, search for “Impact Attenuator”, by ‘Spec Number’, or search for “00225.12”).
