Transportation Synthesis Reports are brief summaries of currently available information on topics of interest to WisDOT staff throughout the department. Online and print sources for TSRs include NCHRP and other TRB programs, AASHTO, the research and practices of other transportation agencies, and related academic and industry research. Internet hyperlinks in TSRs are active at the time of publication, but changes on the host server can make them obsolete. To request a TSR, e-mail [email protected] or call (608) 267-6977. Request for Report The Bureau of Project Development is interested in whether states use expansion joints in concrete barriers, and if so how often and according to what design guidance and specifications. Summary We distributed a survey to members of the AASHTO Research Advisory Committee for completion by appropriate staff at their agencies. The survey consisted of the following questions:
1. Does your state use expansion joints in concrete barriers? If so, please provide relevant specifications and design guidance.
2. How widely or how often does your state use expansion joints in concrete barriers? Staff at 16 state DOTs and one Canadian province responded to this survey. Key findings from the survey include the following:
• Fifteen DOTs use expansion joints, most often every 200 or 400 feet in cast-in-place barriers, and where barriers meet structures or pavement expansion joints.
• One DOT does not use expansions joints. The chart on the following page summarizes these results, and the Survey Results section directly following this chart gives the full text of responses.

State/Province Usage Arkansas Yes – where barriers meet other structures. On rare occasions when demanded by consultant
designs, every 400 feet.
Delaware No. Illinois Yes -- where barriers meet other structures or pavement expansion joints.
Indiana Yes – every 400 feet and where barriers meet other structures.
Kentucky Yes – where barriers meet other structures.
Maryland Yes – rarely. Michigan Yes – every 400 feet and where barriers meet other structures.
Mississippi Yes – always for cast-in-place concrete barriers.

3. Contact Information Howard Yea Director, Bridge Section Government of Saskatchewan Highways and Infrastructure (306) 787-4830 Texas 1. Expansion Joint Usage Yes – always. 2. Specifications and Drawings Current standards call for expansion joints every 100 feet (maximum) for C-I-P roadway installations, and matching transverse joints on concrete pavements. See csb3_prelim.pdf, attached, for bridge joints. 3. Contact Information Bobby Dye Texas Department of Transportation Design Division Roadway Design Section (512) 416-2656 [email protected] Wyoming 1. Expansion Joint Usage Yes – infrequently. There are relatively few locations where Wyoming has had to use expansion joints in concrete barriers. 2. Specifications and Drawings Wyoming typically uses 42 inch single slope barrier which is fairly heavily reinforced. It uses expansion joints at locations where it anticipates movement such as at expansion devices and junctures to existing barrier. Typically Wyoming uses three smooth #8 bars 24 inches long placed longitudinally at the barrier ends. One end of the rebar would be greased and have expansion caps. 3. Contact Information William B. Wilson, P.E. Architectural and Highway Standards Engineer Wyoming Department of Transportation [email protected]

(2) No strength requirements apply.
(3) The Engineer will not apply time limits when falsework is designed to support barrier wall.
601.03.16 Joints.
A) Expansion and Contraction Joints for Structures. Construct expansion joints
to allow absolute freedom of movement. After completing all work, use a fine chisel to carefully remove all loose or thin shells or mortar likely to spall under movement from expansion joints.
Provide and place expansion joints at locations specified in the Plans and Standard Drawings as follows:
1) Friction or Sliding Joints. Friction or sliding joints may be either metal,
neoprene, rubber, or premolded filler type as specified.
601—30
2) Open Joints. Place at locations designated and form by insertion and subsequent removal of a template of timber, metal, or other suitable and approved material. Use a method of insertion and removal of joint templates that avoids the possibility of chipping or breaking the edges and construct the templates so removal is readily accomplished without injury to the work. Do not extend reinforcement across an open joint unless specified in the Plans. Carefully set structural steel angles, channels, plates, or other shapes used in connection with open joints to conform to the crown and grade of the bridge deck. Construct the joint with a uniform opening and to dimensions specified in the Plans.
3) Special Types. Use special types other than those listed when specified in the Plans or when the Engineer so orders in writing. Furnish special details for such joints.
B) Expansion Joints for Non-Structural Items. Install expansion joints at all
breaks in alignment and at all locations where one concrete construction abuts another concrete or other type construction. Install expansion joints at each 1,000 feet of continuous construction. The Engineer will not require steel reinforcement in expansion joints.
When another concrete item crosses an expansion joint in JPC pavements, construct the expansion joint for the structural or non-structural concrete item one inch wide and construct all other expansion joints 1/2 inch wide. The Engineer will not require expansion joints in paved ditches except at locations where the paved ditch abuts another structure. Cut the one-inch thick expansion joint material to conform to the cross section of the concrete.
C) Contraction Joints for Non-Structural Concrete Items. Either form 1/8-inch wide contraction joints for non-structural concrete items or construct them according to requirements of this subsection at intervals not to exceed 30 feet, except when items are constructed on or adjacent to a rigid pavement or shoulder. For these exceptions, make the joint spacing coincide with that of the pavement or shoulder. Space contraction joints for sidewalks as specified in Section 505. The Engineer will not require the sealing of contraction joints in non-structural items.
The Engineer will not require contraction joints for paved ditches. Construct sawed contraction joints to a minimum depth of 2 inches, except that the Engineer will allow one inch of depth for header curbs and integral curbs.
601.03.17 Curing Concrete. Cure reinforced concrete bridge slabs according to
Subsection 609.03. Wet cure all surfaces that are to receive a masonry coating finish, unless using combination material. When using combination material, cure as specified in B) below. Either wet cure all other concrete, except pipe culvert headwalls, as specified in A) below or cure it by application of membrane forming compound as specified in B) below. The Engineer will not require curing for cast-in-place pipe culvert headwalls.
At any time the Engineer determines concrete on the project is not being properly cured, the Engineer may suspend all or any concreting operations on the project.
At any time during the curing period when the atmospheric temperature is 45 °F or less, protect the concrete to satisfy the temperature requirements according to Subsection 601.03.09 D).
A) Wet Curing. Cure concrete for a period of at least 7 calendar days, beginning immediately after placement and finishing, by frequently applying water to all surfaces to keep them continuously damp during the full 7-calendar day curing period or until the required strength is attained. Protect exposed concrete surfaces from drying by application of a double thickness of wet burlap or similar approved material and keep the burlap or other approved material continuously wet for a period of 7 or more calendar days. Soak new burlap in water for at least 12 hours before the first use.

Beginning with the first post where the rail is parallel to the edge of pavement, every sixth post in the line of guide rail shall be reflectorized (96 foot spacing for reflectors) except those posts in the approach terminal and intermediate anchorage area, which curve away from the shoulder, or used in a median barrier. The reflector and method of attachment shall be as indicated on the standard sheet. A. Anchorage Unit Assemblies. After the posts are driven to the specified line and grade,
anchor angles and anchor posts shall be adjusted in the field to provide a full and even bearing on the underlying surface.
B. Cable Tensioning. The Contractor shall install and tension the cable of guide railing and median barrier as follows: Properly seat the spring compensation device and then permanently mark the unloaded position. Complete the assembly of the guide railing and set the compensating devices to a spring compression of 3 1/2 inches. Leave the springs at this setting for at least 2 weeks, then set them to the proper setting according to temperature from the data in the table on the standard sheets.
C. Cable Splicing. The Contractor shall install cable splices in the following manner: Place a splice end over the cable. Twist the cable to separate the three strands. Insert the wedge into the center of the strands, leaving at least one inch of excess cable, and pull the cable back until the wedge is snug to the splice. Pound the wedge into the splice. Crimp at least one wire of the cable over the wedge. Repeat the procedure for the other cable. Connect the two splice ends together.
606-3.03 Box Beam Guide Railing and Median Barrier. Rail sections for tangent runs shall be at least 18 feet long. Rail splices shall be a minimum of 18 inches from the centerline of any post. During non-working hours, exposed approach ends (free ends) of the box beam guide railing or median barrier shall be temporarily terminated with box beam guide railing end assemblies utilizing two splice plates and eight bolts per temporary termination connection. No posts for anchorages will be required. Special temporary splice plates will be needed to adapt box beam guide railing end assemblies to box beam median barrier. 606-3.04 Corrugated Beam Guide Railing and Median Barrier, and Heavy Post Blocked-Out Corrugated Beam Guide Railing and Median Barrier. In the erection procedures, the free end of the rail element shall not be allowed to swing free and cantilever around the mounting bolt.

Single Slope Concrete Barrier, Type D, may be cast-in-place
or slip-formed. See for other standard barrier types and
any details not shown, including materials, adjoining pavement, and
doweling details. Longitudinal steel is not required when top width
of barrier is 12" [300] or greater.
Use a butt longitudinal joint between the barrier and
any adjoining concrete pavement sealed with CMS 705.04 joint sealer.
Raceways on Type D barriers are typically not embedded
within the barrier, but are mounted outside of it on the back side and
not exposed to traffic.
SCD
RM-4.6
End Sections are used when barrier connects to Bridge
Terminal assemblies, Guardrail runs, or Impact Attenuators. See
for Type D End Section details.
At other barrier ends, or at vertical construction
joints, construct a reinforced End Anchorage as shown on Sheet 2.
For Bridge Terminal Assembly, Type 1, details and connec-
tions, see SCD GR-3.1.
Barrier installations that cannot be constructed at the normal
guardrail offset and are to be connected to the approach or trailing
guardrail runs shall have a 25:1 guardrail taper to meet the existing
or normal guardrail offset.
Installations that are not to be connected to the approach or trail-
ing guardrail runs must include the standard guardrail flare as per SCD
GR-5.1.

SECTION A-A
When the barrier is constructed in conjunction
with new asphalt pavement, place it directly on the intermediate course.
Construct the surface course directly against the barrier. Set barrier
placed on existing pavement with a continuous wedge of surface material
tapering from a 1" [25] minimum thickness at the toe of the barrier to
zero. For unidirectional installations, construct the wedge on the tra-
veled way side and the width may be reduced to 12" [300] minimum.
When the barrier is constructed in conjunction with new concrete
pavement, place it directly on the base material. Construct the con-
crete slab against the barrier.
Barrier may be placed on top of existing concrete pavement and
doweled as shown in DOWELING DETAILS (see Sheet 2). When pavement is
to be constructed on one side of the barrier only, then compacted soil
on the opposite side must be placed against the barrier at a minimum
height of 3" [75].
Barrier runs with abutting vertical surfaces at
either required or permissible construction joints are to be doweled
to each other by use of �" [19] dia. by 18" [450] long epoxy coated
deformed dowel bars as per CMS 622.02. Bars are to be placed as shown
on the DOWEL BAR PLACEMENT detail on Sheet 2.
Maximum allowable spacing of unsealed joints is
20’ [6.0 m] throughout the run of the barrier. Construct joints by
using metal inserts inside the forms, preformed full width joint filler,
a grooving tool, or by sawing. Inserts, tooled or sawed joints will have
a 3" [75] minimum depth.
Construct all joints for the full height of the barrier. Saw as soon
as curing will allow to prevent spalling. When used in conjunction with
concrete pavement, match joints to those in the concrete pavement
but not exceeding the maximum allowable spacing.

SCD RM-4.6
MATERIALS:
CONTRACTION JOINTS:
Construct using Class C concrete. Construct top and end
edges with either a 1" [25] radius or �" [19] chamfer, except at light
pole foundations.
ADJOINING PAVEMENT:
SEALING JOINTS:
TRANSITIONS:
CONSTRUCTION JOINTS:
Use a butt longitudinal joint between the barrier and
adjoining concrete pavement sealed with CMS 705.04 joint sealer. See
detail on Sheet 2.
STATION MARKINGS:
RACEWAY:
Impress markings in the "green" concrete on both
sides at the top of the barrier. The cost is incidental to the unit cost
bid for this barrier.

10 ft. [3 meters].
Maximum allowable spacing of unsealed joints is
20’ [6.0 m] throughout the run of the barrier. Construct joints by
using metal inserts inside the forms, preformed full width joint filler,
a grooving tool, or by sawing. Inserts, tooled, or sawed joints will
have a 3" [75] depth. Construct all joints for the full height of the
barrier. Saw as soon as curing will allow to prevent spalling. When
used in conjunction with concrete pavement, match joints to those in
the concrete pavement but not exceeding the maximum allowable spacing.
When the barrier is constructed in conjunction
with new asphalt pavement, place it directly on the intermediate
course. Construct the surface course directly against the barrier.
Set barrier placed on existing pavement with a continuous wedge of
surface material tapering from a 1" [25] minimum thickness at the
toe of the barrier to zero. For bidirectional installations construct
the wedge on both sides of the barrier. For unidirectional installations,
construct the wedge on the traveled way side and the width may be
reduced to 12" [300] minimum.
When the barrier is constructed in conjunction with new concrete
pavement, place it directly on the base material. Construct the
concrete slab against the barrier.
Barrier may be placed on top of existing concrete pavement and
doweled as shown in DOWELING DETAILS (see Sheet 2). When pavement
is to be constructed on one side of the barrier only, then compacted
soil on the opposite side must be placed against the barrier at a
minimum height of 3" [75].
Make linear transitions between different types of
barrier within a 20’ [6.0 m] length.
Locate as shown on in RACEWAY PLACEMENT Detail, unless
otherwise directed by the Engineer. Ensure that the electrical race-
way is clear of obstructions.
Cost of the 4" [100] polyvinyl chloride raceway is included where
shown on the plans. The cost for additional raceways and No. 10 AWG
copperclad or aluminum-clad wire is also included where shown on the
plans for future installation of circuits.
