WO 2011/040902 PCT/US2009/058704 2 Detailed Description [12] Median barriers, which typically are relatively heavy devices that are frequently utilized for separating lanes of traffic from other lanes of traffic, construction work, etc. The barriers typically must be sufficiently heavy such that, if accidentally contacted by a moving vehicle, they will prevent the moving vehicle from leaving its lane, thereby protecting construction workers, pedestrians, and/or other lanes of traffic on the other side of the median barrier. [13] Pre-cast reinforced concrete can be used to form median barriers. Yet to be most effective, there is a need to ensure that vehicles generally cannot pass through or substantially move a median barrier and thereby create a hazard to the adjacent lane of traffic, constructions workers, pedestrians, etc. [14] Median barriers can have certain resistance to movement caused by the weight of the barrier and the static coefficient of friction between the lower surface of the barrier and the roadway and/or other surface upon which the barrier is located. Because this coefficient of friction is generally fixed, the resistance to lateral movement is generally proportional to the weight of the barrier. For the convenience of construction crews, temporary barriers are often constructed with a length on the order of 12 feet, although longer or shorter barriers can be provided if the need arises (if, for example, it were necessary to have barriers around a very sharp curve, shorter barriers might permit the outer edge of the curve to be lined with barriers without the barriers intruding on the roadway). Unfortunately, as a barrier becomes smaller, its weight typically becomes less and, thus, its resistance to lateral movement becomes less. This can create challenges when a need arises for both a resistance to impact-generated movement and a non-linear grouping of barriers. [15] One answer to the problem of barriers being shifted under vehicle impact is to involve the weight and mass of adjacent barriers such that several adjacent barriers must be moved in the event of a vehicle impact, thereby providing greater WO 2011/040902 PCT/US2009/058704 3 resistance to lateral movement of the struck barrier. Exemplary embodiments of such an approach are described here, where similar exemplary structures are similarly numbered among the various figures in the drawings. [16] FIG. 1B is a side view of an exemplary embodiment of a precast concrete barrier 10, showing longitudinally-extending top face 61, longitudinally-extending bottom face 62, end face 63, and end face 64. FIG. 1A is a side view of an exemplary female interlocking structure 14 on one end of barrier 10, and showing longitudinally-extending side faces 65 and 66. FIG. IC is an end view of the other end of the barrier in FIG. 1B showing an exemplary male interlocking structure 12 located thereon. Depicted in phantom lines are an exemplary connection structure for interconnecting the male interlocking structure 12 with the female interlocking structure 14 internal to barrier 10. [17] Barrier 10 can be constructed of reinforced concrete having a minimum compressive strength at the age of approximately 28 days of approximately 4,000 psi. Reinforcement in barrier 10 can conform to ASTM A615, Grade 60. The standard length for an exemplary barrier can be approximately 12 feet with the male portion protruding from the end of the barrier by approximately 1-7/8 (1.875) inches. The width of the body of the exemplary barrier shown in FIGS. 1A and IC can be approximately 24 inches and the height can be approximately 32 inches. The body can be cast directly and/or in multiple units. For example, if a length less than approximately 12 feet be desirable, such length can be cast directly, and if a section longer than approximately 12 feet be needed, it can be cast as one unit, or as two or more units. [18] The interrelationship of an exemplary male interlocking structure 12 and an exemplary female interlocking structure 14 with a respective exemplary barrier 10 is shown in FIG. 4. As can be seen, either the male end of an elevated leftmost barrier or the female end of an elevated right-hand barrier can be lowered vertically so as to interengage the web 20 and flange 22 of male interlocking WO 2011/040902 PCT/US2009/058704 4 structure 12 with the slot 30 and tube 26 of female interlocking structure 14. As shown, in certain exemplary embodiments, there can be a gap and/or separation of approximately 0 inches to approximately 4 inches, including all values (e.g., approximately 0.76, 1, 1.252, 1.5, 2, etc., inches) and subranges therebeween, between barriers when the barriers are pulled as far apart as possible while in the interconnected state. This gap can permit one barrier to be canted with respect to another so as to permit a curve in a line of barriers without disengaging the interlocking portions of the barriers. Furthermore, the barriers can continue to form a structural interconnection between adjacent barriers when forming a curve or other non-linear pattern along a roadway, median, etc. This spacing also can permit barriers to be interengaged and/or interlocked when there is a vertical displacement, i.e., the line of barriers begins to go up and/or over a hill and/or otherwise encounters a change in grade and/or elevation. [19] Male interlocking structure 12 and female interlocking structure 14 can be respectively interconnected internally to barrier 10. FIGS. 2 and 3 show these interlocking structures. Each of reinforcing bars 40 and 42 can comprise a section of, for example, number 5 or number 6 rebar measuring approximately 11 foot 8 inches. Note that the number of reinforcing bars shown in the drawings is conceptual only, and the actual number implemented in a particular barrier can depend on the design requirements of that barrier. [20] These interconnecting reinforcing bars 40 and/or 42 can be welded to anchor bars 24 and 28 that can be connected to male interlocking structure 12 and female interlocking structure 14, respectively. Note that the number of anchor bars shown in the drawings is conceptual only, and the actual number implemented in a particular barrier can depend on the design requirements of that barrier. In certain exemplary embodiments, interconnecting rebar 40 and/or 42 merely can be wired to be substantially adjacent corresponding anchor bars 24 and/or 28 as shown in the phantom lines of FIGS. 1A and 1B. This can facilitate precise alignment of male interlocking structure 12 and/or female interlocking structure WO 2011/040902 PCT/US2009/058704 5 14 while the concrete is poured and/or cured. The overlap in which interconnecting reinforcing bars 40 and/or 42 coextend with anchor rods 24 and/or 28 of male interlocking structure 12 and/or female interlocking structure 14 can be equal to approximately 40 diameters of the larger reinforcing bar, which can provide substantially the same structural strength as welding the bars together. [21] As shown in FIG. IB, edges and/or major surface intersections (e.g., top face to end face, bottom face to end face, side face to end face, etc.) 51, 52, 53, and/or 54 can be sharp, perpendicular, notched, angled, beveled, chamfered, rounded, and/or arced. By notching, angling, beveling, chamfering, rounding, arcing, and/or otherwise causing edges and/or major surface intersections 51, 52, 53, and/or 54 (e.g., by beveling (chamfering) and/or cutting back the intersections by approximately 0.75 inches) to transition from the longitudinally-extending major faces to the end faces of the barriers by other than perpendicular intersections, interconnected barriers 10 can have greater freedom to be positioned at an angle with respect to each other's longitudinal axis as measured in a substantially vertical plane without substantial compromise of the strength and/or crash worthiness of barrier 10. [22] FIG. 4 is a plan cross-sectional view taken at section A-A of FIG. 1B. As shown edges and/or major face intersections (e.g., right side surface to end surface, left side surface to end surface, top face to end face, etc.) 56, 57, 58, and/or 59 can be sharp, perpendicular, notched, angled, beveled, chamfered, rounded, and/or arced. By notching, angling, beveling, chamfering, rounding, arcing, and/or otherwise causing edges and/or major face intersections 56, 57, 58, and/or 59 to transition from the side and/or longitudinally extending major surfaces to the end surfaces of the barriers by other than simple perpendicular intersections, interconnected barriers can have greater freedom to be positioned at an angle with respect to each other's longitudinal axis as measured in a substantially horizontal plane.

WO 2011/040902 PCT/US2009/058704 6 [23] FIGS. 5A and 5B show the details of an exemplary embodiment of the male interlocking structure 12 comprising web 20 and flange 22, respectively. In certain exemplary embodiments, web 20 can have the form of a substantially rectangular plate that can extend substantially vertically for approximately 6 inches to approximately 18 inches, including all values (e.g., approximately 7.5, 8, 10, 12, 13.75, 15, etc. inches) and subranges therebetween, and/or can extend substantially longitudinally from an end face of barrier 10 by approximately 2 inches to approximately 8 inches, including all values (e.g., approximately 2.5, 3, 3.75, 5.543, 6, 7.25, etc., inches) and subranges therebetween. Flange 22 can have the form of a substantially rectangular plate that can: be positioned substantially orthogonally to web 20, extend along any portion of the substantially vertical length of web 20, and/or have a width of approximately 1 inch to approximately 3 inches, including all values (e.g., approximately 1.364, 1.75, 2, 2.5, etc., inches) and subranges therebetween. In certain exemplary embodiments, web 20 can be welded to flange 22 to form a "T" shape (although the combination can be cast, forged, and/or otherwise machined in one substantially monolithic piece). [24] Welded to web 20 can be a number of anchoring bars 24 that can serve to aid in anchoring web 20 in the end of concrete barrier 10. Reinforcing bars 24 can be, for example, number 6 A706 rebar. In the exemplary embodiment shown in FIGS. 5A and 5B, the rebar can measure from approximately 2 feet to approximately 5 feet in length, including all values (e.g., 2.5, 2.78, 3, 3.777, 4, etc., feet) and subranges therebetween, and/or can be welded to the web 20 where it is in contact therewith. Web 20 and/or flange 22 can measure approximately one-half inch thick and/or can be standard steel, e.g., A36 (FYE close 36 ksi), structural steel, and/or high strength structural steel, e.g., A500 (FYE close 39 ksi).

WO 2011/040902 PCT/US2009/058704 7 [25] Referencing FIGS. 6A and 6B, female interlocking structure 14 can be a tube 26 which can have any desired cross-sectional shape (e.g., triangular, square, rhomboid, rectangular, hexagonal, round, etc.), can be constructed of structural steel, can measure, for example, approximately one-half inch thick and approximately 4 inches square, can extend for a predetermined portion of the height of the barrier, and/or can be positioned in a predetermined position with respect to the height of the barrier (e.g., substantially centered, offset by approximately 2 inches from center, raised approximately 10 inches from the bottom surface of the barrier, etc.). The longitudinal axis of tube 26 can be substantially orthogonal with the longitudinally extending direction of the barrier. Substantially parallel with the longitudinally extending direction of the barrier and/or affixed and/or welded to the sides of the substantially vertically oriented tube 26 can be sections of anchoring bars 28, which can be approximately 2 feet in length. Anchoring bars 28 can serve to anchor tube 26 in the reinforced concrete of the median barrier. In the portion of tube 26 external to the concrete material of median barrier 10 can be a vertically extending slot 30 that can have a width greater than the thickness of web 20, such as approximately 1 inch. The edges of tube 26 defined by slot 30 can be perpendicular, angled, beveled, chamfered, arced, rounded, etc. [26] In certain exemplary embodiments, flange 22 can be in the form of a steel structural tube having smaller outside longitudinal cross-sectional dimension(s) than the inside longitudinal cross-sectional dimension(s) of tube 26. For example, if tube 26 has a circular longitudinal cross-section with an inner diameter of 4 inches, flange 22 can also have a circular longitudinal cross-section, but with an outer diameter of less than 4 inches, so that flange 22 is free to move longitudinally with respect to tube 26. As another example, if tube 26 has a square longitudinal cross-section with an inner dimensions of 3 inches by 3 inches, flange 22 can also have a square longitudinal cross-section, but with outer dimensions of less than 3 inches, so that flange 22 is free to move longitudinally with respect to tube 26. The intersection of web 20 with flange 22 would likely WO 2011/040902 PCT/US2009/058704 8 form a cross-sectional shape of other than a "T" shape in such embodiments. Nevertheless, because the width of slot 30 can be less than the dimension of flange 22 measured in the same direction, relative non-longitudinal movement between the flange and tube of two interlocked barriers would be substantially limited, effectively making the two barriers substantially inseparable in response to vehicular impact. [27] FIG. 7 is a plan view of an exemplary group of interconnected exemplary barriers 72, 74, and 76, and shows that such barriers can form a curve in a substantially horizontal plane, that curve having, for example, a minimum radius of approximately 50 feet to infinity, including all values (e.g., 63.7, 85, 102.33, 125, 160, 200, 400, 800, etc.), and subranges therebetween, when measured to the innermost surface (or outermost surface if desired) of the barriers with respect to an axis of the curve. Thus, any adjacent pair of such barriers can form an angle with respect to each other's longitudinal axis, as measured in a substantially horizontal plane, of approximately 0 to approximately 15 degrees, which is equivalent to approximately 0 to approximately 16.7 percent, including all values (e.g., approximately 5, 6.1, 7.5, 8.04, 10, 12.5, etc., degrees, and/or approximately 5.6, 6.5274, 8.5, 9, 11.25, 14, etc., percent) and subranges (e.g., between 3.1 and 7.94 degrees, 5 degrees to 10 percent, at least 5 degrees, greater than 6 percent, etc.) therebetween. [28] FIG. 8 is a side view of an exemplary group of interconnected exemplary barriers 82, 84, and 86, and shows that such barriers can accommodate a grade change (A) in a substantially vertical plane, that grade change having an angle measuring approximately 0 degrees to approximately 4 degrees. Thus, any adjacent pair of such barriers can form an angle with respect to each other's longitudinal axis, as measured in a substantially vertical plane, of approximately 0 to approximately 4 degrees, which is equivalent to approximately 0 to approximately 4.5 percent, including all values and subranges therebetween, such as 2.75 degrees, 3.8 percent, greater than 3 degrees, etc.

WO 2011/040902 PCT/US2009/058704 9 [29] For any substantially identical pair of interconnected barriers, the maximum possible degree (or percent) of the angle between the longitudinal axes of those barriers' bodies can be affected by any combination of: * the primary materials, properties, and/or dimensions of barrier 10 and/or its components; * how far web 20 extends from the end face of barrier 10 (i.e., the longitudinally-extending width of web 20); * the dimensions, thickness, and/or height of web 20 and/or flange 22; * the position of web 20 and/or flange 22 with respect to the major faces of barrier 10; * the dimensions, thickness, height, and/or position of tube 26; * the dimensions and/or position of the slot and/or space defined by tube 20 in which web 20 and/or flange 22 can move; * the dimensions, position, and/or distance of male interlocking structure and/or female interlocking structure with respect to one or more longitudinally-extending major faces of barrier 10; and/or * the technique via which, one or more longitudinally-extending major faces transitions to one or both end faces of barrier 10 and/or the degree to which the otherwise perpendicular intersections of such faces are angled, beveled, notched, arced, rounded, trimmed, cutback, removed, and/or smoothed, etc.; * etc. [30] In certain exemplary embodiments, interconnecting bars and/or anchor bars can be mechanically connected, e.g., through U-shaped bolts and/or extending through holes in the structural tube and/or web to aid in connecting the interlocking components to their respective ends of the pre-cast concrete median barrier. In certain exemplary embodiments, different numbers of interconnecting bars and/or anchor bars and/or different sizes of bars can be used to maintain a WO 2011/040902 PCT/US2009/058704 10 secure connection between the interlocking structures and their respective barriers. [31] In certain exemplary embodiments, different arrangements of webs and/or flanges can be used as long as the web can be inserted vertically into the slots of the female interlocking structure and the flange is wider than the slot so as to prevent disengagement in any direction other than a substantially vertical direction. [32] Median barriers constructed in accordance with certain exemplary embodiments disclosed herein have met or exceeded, in independent crash tests, the Federal Highway Administration standards for median barriers and in particular the American Association of State Highway and Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) Test Level-3 (TL-3). These tests confirm that certain exemplary interlocked barriers did not separate and/or become disengaged even though impacted by a 2.205 ton pickup traveling at 63.3 miles per hour at a 25.66 incidence angle with the barrier.
