  "description": "This crop is a detail sheet showing the construction of a 1-inch expansion joint within a concrete barrier, illustrated in plan, elevation, and side elevation views. It specifies a 3/4-inch chamfer, 1-inch preformed joint filler, and low modulus silicone sealant (Type A) at the joint, with the filler held in place using 10d galvanized nails. The side elevation shows the tapered barrier profile with a 3-inch offset dimension near its base."
