About this file
This document is a standard plan from the Michigan Department of Transportation (MDOT) Bureau of Development for load transfer assemblies used in concrete pavement construction and repair. The plan provides detailed specifications for the design and assembly of expansion and contraction joints, including dowel bar and spacer wire dimensions, placement, and installation requirements. It also includes notes on acceptable materials, welding, and alignment tolerances.
The related state and local contract opportunity involves concrete pavement repairs along US-24 (Telegraph Rd) at the Elizabeth Lake Rd ramp in Oakland County and Pentwater Village, Michigan. The project requires a prequalified maintenance contractor and bid bonds. No additional details are provided about the specific scope of work, quantities, response deadlines, or contract term.

THE SIDE SUPPORT WIRE (U-LEG, J-LEG DR V-LEG( MAY BE INSTALLED ON
EITHER THE INSIDE OR THE OUTSIDE OF THE LONGITUDINAL SPACER WIRES.
THE DIMENSION FROM THE END OF THE DOWEL BAR TO THE CENTER OF THE
TOP LONGITUDINAL SPACER WIRE SHALL BE A MINIMUM OF 11,2". THIS
DIMENSION APPLIES TO SIDE SUPPORT WIRES INSTALLED ON EITHER THE
INSIDE OR THE OUTSIDE OF THE LONGITUDINAL SPACER WIRES.
WIRES:
ALL WIRES SPECIFIED (EXCEPT SHIPPING TIE WIRES) ARE MINIMUM NOMINAL
SIZES ALLOWED. (DO NOT EXCEED THE MAXIMUM NOMINAL DIAMETER OF
0.177" FOR SHIPING TIE WIRES.)
ALL WIRES SHALL CONFORM TO THE CURRENT SPECIFICATIONS FOR CARBON
STEEL WIRE FOR GENERAL USE, A.S.T.M. DESIGNATION A-853, GRADE 1008
OR GREATER. UNLESS OTHERWISE SPECIFIED, MINIMUM TENSILE STRENGTH
REQUIREMENTS SHALL BE 60 ksi.
ALL WIRE INTERSECTIONS ARE TO BE ARC OR RESISTANCE WELDED.
STAKES TYPICALLY APPLIED AT WORKING ENDS OF DOWELS WITH SUFFICIENT
INSTALLATIONS TO PREVENT UNIT FROM OVERTURNING UNDER LOAD.
DO NOT CUT FILLER SPACER WIRES AFTER THE LOAD TRANSFER ASSEMBLY IS
SET IN PLACE.
DOWEL BARS:
DOWEL BARS ARE TO BE ACCORDING TO THE STANDARD SPECIFICATIONS FOR
CONSTRUCTION.
EPDXY COATED DOWEL BARS ARE TO BE FACTORY COATED WITH A VISIBLE
COATING OF AN APPROVED BOND RELEASE AGENT, UNIFORMLY APPLIED
BY DIPPING AND WITHOUT EXCESSIVE DRIPS OR THICKNESS IN SUCH A
THICKNESS THAT ITS PRESENCE CAN BE READILY IDENTIFIED.
METAL EXPANSION CAPS MUST BE ENTIRELY CLOSED AT ENDS BY CRIMPING.
PLASTIC CAPS MUST HAVE A POSITIVE STOP. DO NOT DRIVE CAPS BEYOND
THEIR STOP. EXPANSION CAPS MUST HAVE A SUITABLE STOP TO ENSURE
THAT THE END OF THE CAP MAINTAINS A DISTANCE OF 1" (EXPANSION) FROM
THE END OF THE DOWEL DURING CONCRETE PLACEMENT.
DOWEL BARS SHALL BE COATED WITH EPDXY COATING ACCORDING TO
THE STANDARD SPECIFICATIONS FOR CONSTRUCTION. CUT ENDS ARE NOT
REQUIRED TO BE COATED.
DOWEL BAR DIAMETER PAVEMENT THICKNESS
1" 6" - LESS THAN 8'
114' 8" - 10"
11,2" GREATER THAN 10"
DOWEL BARS SHALL BE ALIGNED PARALLEL TO EACH OTHER IN THE ASSEMBLY
ON 1'-0" (± 1/2") CENTERS.
AFTER THE LOAD TRANSFER ASSEMBLY IS SET IN PLACE, DOWEL BARS SHALL
REMAIN ALIGNED (PARALLEL) WITH EACH OTHER IN THE VERTICAL AND
HORIZONTAL PLANES OF THE PAVEMENT TO WITHIN 14 FOR THE ENTIRE
LENGTH OF THE BAR.
DOWEL BARS SHALL BE PLACED AT MID DEPTH OF THE SLAB UNIFORMLY
ALIGNED WITHIN 14 FOR THE ENTIRE LENGTH OF THE BAR.
FOR PAVEMENTS WITH VARIABLE THICKNESS TRANSVERSLY ACROSS THE SLAB,
THE TOP AND BOTTOM SURFACES OF THE DOWEL BAR SHALL BE WITHIN THE
MIDDLE i/3 OF THE PAVEMENT THICKNESS, AS APPROVED BY THE ENGINEER.
