Abstract: A roadway guardrail system including a rail and plurality of support posts assembled such that upon impact from a vehicle the rail moves upwardly with respect to the post. Fasteners may be used in the operative coupling of the rail to the support posts, such that upon impact the fasteners move upwardly with respect to the support posts and the rail moves upwardly along with the fasteners. The guardrail system may further include a reinforcing member that is slidable along the post and operatively coupled to the rail with the fasteners, such that the rail and fasteners slide along with the reinforcing member with respect to the support posts. The reinforcing member may be a spacer of various shapes, a washer, an additional rail section, or other type of member that allows the rail to slide upwardly with respect to the post.

Abstract: A block (100) for a lane separator having a first end with recess (132) and protrusions (131, 133) and a second end (140) with a complementary protrusion (142) and recesses (141, 143) such that the projections and recesses (131-133; 141-143) fit into the recesses and protrusions of the neighboring blocks of the same shape as the block (100), wherein the recesses and protrusions are provided with bores (160) adapted to receive a cylindrical locking pin (150). The base portion (110) having vertical side walls (111, 112) that prevents a vehicle from climbing onto the block. The locking pin (150) is formed of a hollow, deformable tube, so that kinetic energy of a collision to a greater extent than before deforms the block, and to a lesser degree the vehicle. The block is hollow and can be deployed manually without tools, and then filled with water, sand or similar to the desired weight. The lane separator can also be used as a foundation for signs, and more.

Abstract: A highway guardrail terminal having horizontally extending guardrail elements mounted on a plurality of vertical posts. An anchor cable release mechanism having a cable release bracket attached to a W-beam rail element by cable release bolts has an arrangement of tapered slots and elongated openings to quickly release the cable release bracket from the W-beam rail element upon end-on vehicular impact to the terminal. The tapered slots have a geometry which lifts the bracket away from and out of a parallel alignment with the W-beam rail element.
