1 inch maximum.
• Horizontal translation (relative to the intended location, across the joint): 1 inch.
• Vertical translation (relative to the intended depth of the constructed pavement): as shown on the Standard Drawings.
When LTU are used, secure them in place at the designated locations as shown on Standard Drawings in advance of paving operations to prevent their movement during paving operations. Before paving, demonstrate the fastening method to the Representative for approval. Before paving, apply bond- breaker lubricant to at least one-half of the length of Type B coated dowel bars, unless a bond- breaker lubricant has been applied in the shop. Stir the lubricant well and apply to the free end of dowels by spraying, or with a gloved hand, to produce a thorough coating. Do not use brushes for lubricant application. Apply the bond- breaker lubricant, as specified, at least 1 hour before placing the concrete around the dowel assembly. Type A coated dowel bars do not need lubricant . Where existing concrete pavements are widened, align transverse construction or contraction joints, if possible, with existing construction or contraction joints or cracks; otherwise, do not place within 10 feet of a joint. When constructing adjacent concrete pavement , shoulders , or structures after pavement construction, seal the ends of all transverse joints and cracks to prevent intrusion of cement mortar into the joints and cracks. In these cases, when saw cutting transverse joints in the newly constructed lane or shoulders, saw cut the existing transverse joint in the previously placed lane to ensure the removal of any mortar that might have intruded into the joint.
construct a transverse joint using a bulkhead. Place dowels in bulkheads by drilling or inserting into fiberglass dowel sleeves. Do not construct a transverse joint within 10 feet of an other transverse joint. If not enough concrete has been placed or mixed at the time of interruption to form a slab at least 10 feet long, remove concrete to the preceding joint and dispose of excess mix.
center of the sawed transverse contraction joints. The sawed trans verse joint must be located directly ±1 inch over the centerline of the dowel basket assemblies or the centerline of the mechanically implanted dowels. Saw joints with equipment having guides, a blade guard, water cooling system, and cut -depth control. Provide adequate and extra equipment and parts at the site, before placing concrete and during sawing operations. Saw joints as soon as concrete
