摘要: A safety roadway delineator includes one or more elongate recessed marker surfaces which are coated with a reflective material, preferably a retroreflective material such as reflective glass beads. The recessed marker surfaces are vertical or at least inclined to the horizontal to insure water run-off and are formed either directly in cast-in-place concrete roadway members or in pre-cast polymer concrete facing panels which are attached to the cast-in-place concrete roadway members. The roadway delineator is substantially continuously protected from normal wear and reliably exhibits reflectivity both under dry and rainy weather conditions.

摘要: In a breakaway coupling (10) for a highway and roadside appurtenance, a controlled breaking region (14) is provided which has at least two axial spaced necked-down (16,18) portions coaxially arranged between the axial ends (13,13') of the coupling (10) which are configured to be attached both to the appurtenance, at one end, and to the support base (B), at the other end. Each necked-down portion (16,18) essentially consists of two axially aligned conical portions (60,62,64,66) inverted one in relation to the other and generally joined at their apices to form a generally hour-glass configuration having a region of minimal cross section at an inflection point (16',18') having a gradually curved annular concave surface defining a radius of curvature. Each of the two necked-down (16,18) portions has different radii of curvature that at respective inflection points (16',18') to provide preferred failure modes as a function of the position and direction of impact of a force on the appurtenance. The breakaway coupling (10) preferably has a minimum ultimate tensile strength equal to or greater than about 53.8 kN and a minimum ultimate restrained shear strength equal to or greater than about 5.8 kN. The minimum ultimate restrained shear strength of the breakaway coupling (10) is preferably about from about 6% to about 12% of the minimum ultimate tensile strength.
