751.13.1 Expansion Devices

751.13.1.1 General

The number of movable deck joints in a structure should be minimized. Deck joints should be avoided over roadways, railroads, sidewalks, other public areas, and at the low point of sag vertical curves.

Consult the Structural Project Manager, if the use of special covering floor plates in shoulder areas should be considered.

If no expansion device is specified in the Design Layout, but due to the length of structure an expansion device is required, consult the Structural Project Manager for the type to be used. The roadway surface gap, W, (Except Flat and Finger Plates) in a transverse deck joint, measured in the direction of travel shall satisfy:

For single gaps:

1" ≤ W ≤ 4"

EXPANSION JOINT SELECTION
	Allowable Movement	Allowable Skew
Preformed Compression Joint Seal	0 – 2”	≤ 20˚
Strip Seals	2” to 4”	≤ 45˚
Flat Plate		> 45˚
Finger Plate

Movement Calculation (in the direction of travel)

$\,\triangle =\gamma (coefficient)(temperature\ range)(actual\ expansion\ length)$

$\,\gamma$ = Load factor for temperature movement

Coefficients, ($\,\alpha$)

Steel:	Thermal - 0.0000065 ft/ft/F°
Concrete:	Thermal - 0.0000060 ft/ft/F°

Temperature Range From 60°F, ($\,\alpha$)

Temperature Range is based on a design installation temperature of 60°F.

	Rise	Fall	Range
Steel Structures	60°F	90°F	150°F (From -30° to 120°)
Concrete Structures	50°F	70°F	120°F (From -10° to 110°)

Actual Expansion Length, (L)

When Expansion joints are used for long span structures with deep girders, movement calculations should also consider the bearings and possible resulting girder rotation.

Installation Width
The installation width, gap, should be adjusted for temperatures above or below the design installation temperature. Movement for a 10°F change in temperature should be indicated on the plans to the nearest 1/16” by using the appropriate note.

Movement for 10°F change in temperature = (α)(10°F)(L)(Cos θ)

751.13.1.4 Details of Substructure Protection

A protective coating shall be applied to concrete surfaces exposed to drainage from the roadway. Indicate surface to be coated on plans. Urethane resembles black tar which is used where aesthetics is not a concern, otherwise use epoxy.

Note: Epoxy coat all reinforcement in end bents with expansion joint system.

751.13.2 Silicone Expansion Joint Sealant

Silicone expansion joint sealant systems (SEJS) shall not be used for normal contract new or rehabilitation jobs effective November 2011. This system is considered a short term sealing solution primarily good for maintenance operations.

SEJS may be considered for special situations when agreed upon by both the district bridge engineer and Bridge Division. Examples include short deck spans, sawed joints or situations where contracted joint work is intended to supplement MoDOT’s bridge maintenance work scheduling (maintenance type applications).

Archived SEJS details including armor and reinforcing steel details are available upon request from the Bridge Division.

751.13.3 Preformed Compression Joint Seal

751.13.3.1 General

The system can be used for movements up to 2" with skews ≤ 20°.

751.13.4 Strip Seal Expansion Joint System

751.13.4.1 General

Strip Seal Expansion Joint Systems should be used for movements greater than 2” and less than 4” for skews < 45°. Use flat plate expansion devices on curved structures and skews over 45°.

The installation width, gap = 2”, based on a design installation temperature of 60°F.

On skewed bridges, the strip seal expansion devices must be checked for parallel and perpendicular movements. Parallel movements (Racking) shall be less than 1 ½” for either rise or fall movements. Maximum skew shall be 45°.

Formulas: M = 1.2(ΔT)(α)(L) : Bridge total movement or individual rise and fall movements

ΔT = Corresponding temperature range

L = Expansion length

α = Coefficient of linear expansion

M$\,\bot$ = M cos θ : Movement perpendicular to joint
M$\,\ ||$ = M sin θ : Movement parallel to joint

751.13.4.7 Drainage Details

In order for strip seal expansion joint systems to function properly, the gland shall be allowed to drain to prevent build-up of debris. Debris may punch holes in the gland and the extra load may possibly pull the gland from the extrusions.

To prevent debris buildup on the strip seals the gland should not be turned up at the barrier curb. Instead, the steel armor with extrusions should be extended to the face of the slab through the barrier curb.

Drainage shall be handled by one of two methods. The first method is to let the water run off the gland and free fall to the ground below. The gland should extend past the edge of slab 3 inches minimum. At intermediate bents, the bent cap should have a protective coating applied to prevent moisture saturation of the concrete. On structures where there is an adjacent structure separated by a median barrier curb with an open joint (Type D or Split Median) the gland should be terminated at some point under the curb at all bent types and protective coating should be applied at all faces exposed to moisture. The second method of drainage is to provide a fiberglass pipe drainage system to collect water at the bents.

See the Structural Project Manager for the method of drainage to be used. The following pages provide some possible details that may be used for strip seal expansion joint drainage systems.

If the fiberglass pipe drainage system is used, payment will be made under the pay item. Drainage System (On structure), Lump Sum.

751.13.4.8 Polymer Concrete

Strip Seal Expansion Joint System may be used on rehabilitation projects where other expansion devices need to be replaced. Consult with Structural Project Manager about the use of polymer concrete with strip seals. Strip seal is to be designed with the same requirements as a normal strip seal expansion joint system.

Note: Anchorage system shall be welded to strip seal steel armor with appropriate weld to meet AASHTO Fatigue for connection.

751.13.5 Flat Plate Expansion Devices

751.13.5.1 General

Flat Plate Expansion Joint System should be used where Strip Seals and Preformed Compression Joints can not be used due to large expansion lengths or curved structures or skews over 45˚.

The installation width, sub-surface gap = 3 1/2 in. is based on a design installation temperature of 60˚F.

Design movement for Flat Plate Expansion Devices is limited by the following criteria:

1. Full closure of surface gap.

2. Min. sub-surface gap = 1 in. (┴ to joint)

3. Min. plate overlap = 1 1/2 in. (┴ to joint)

Note: Criterion 3 controls for standard details for both concrete and steel superstructures. Originally, the details for EPG 751.13.5 used a 3/4 in. x 7/8 in. bar, that allowed for a 2 ½ in. gap contraction (┴ to joint). Functionally, the 3/4 in. x 7/8 in. bar is preferred but it is not available domestically as of July 2010. A 7/8 in. x 7/8 in. bar is shown as the standard in EPG 751.13.5 primarily due to domestic availability.

Flat Plate expansion devices can be used bridges of any skew.

Maximum Expansion Length1
Skew	Concrete Bridge	Steel Bridge
0°	496 ft.	356 ft.
10°	504 ft.	362 ft.
20°	528 ft.	379 ft.
30°	573 ft.	411 ft.
40°	648 ft.	465 ft.
50°	772 ft.	554 ft.
60°	992 ft.	712 ft.
1 This table is applicable for standard details found in EPG 751.13.5 and for joints where movement is expected from one side of the joint. When movement is expected from both sides of the joint, the sum of the expansion lengths participating at a joint should not exceed the values in this table. When larger expansion lengths are required, the surface gap, sub-surface gap and flat plate dimensions shall be determined by design.

The max. surface gap requirement, W ≤ 4 in. is not considered for flat plate expansion devices since the surface gap neither impairs the riding characteristics of the roadway, nor damages vehicles nor destroys the function of the joint.

Dimensions shown are perpendicular to centerline of joint and do not vary with skew.

Part longitudinal sections for bridges on grades or verticle curves having a plate type intermediate expansion device shall be detailed with the expansion plate anchor to the long span side. If equal spans, then place expansion plate anchor on the high side. For bevel plate and permissible field splice details, see Bridge Standard Drawings.

Slotted wells in prestressed girders shall be located and shown on plans as between reinforcement bars or WWF.

Use bevel plate at end bents only when the grade of the slab is 3.0% or more. Modify the roadway plate, the 5/8 in. vertical plate and the continuous bar when the bevel plate is required.

751.13.6 Finger Plate Expansion Devices

751.13.6.1 General

The max. roadway surface gap (W) shall meet the following criteria:

When W(Long.) < 8", Then W(Tran.) < 3".

OR

When W(Long.) > 8", Then W(Tran.) < 2".

The min. finger overlap = 1.5"

Expansion lengths are calculated from the total movement value by the following equation:

Expansion length = $\,{\frac {Movement}{1.2\left(\alpha \right)\left(T\right)}}$

Where:

Max. Length of Expansion, ft. (1)		Total Movement, inches	Gap at 60° F, inches
Concrete	Steel
385	284	4	2 3/4
578	427	6	3 1/2
1 Longer expansion lengths are possible but they must be designed.

For Concrete:

$\,\alpha$ = 0.000006 ft/ft/˚F

$\,T$ = 120˚F

For Steel:

$\,\alpha$ = 0.0000065 ft/ft/˚F

$\,T$ = 150˚F
