Timely sawing of transverse contraction joints. 12. Restriction of loads on pavement until it has gained the required strength. 4-10.1.3 Smooth Ride A smooth form or track line, a uniformly stable foundation, and equipment in good mechanical condition and adjustment all contribute to good ride. Variation in the mix can cause variations in the pavement surface that lead to poor riding pavements... Transverse construction joints shall be made at the end of each day's run or when interruptions occur in the concreting operation. Transverse construction joints shall be formed at a contraction or expansion joint,

Concrete Runway Construction Lessons Learned The runway pavement was constructed using a slip form paver 12.2 m ( 40 ft) wide. Joint spacing was 6.1 m by 6.1 m (20 ft by 20 ft). The longitudinal construction and contraction joints in the thicker central portion of the runway were provided with dowels for load transfer. Longitudinal construction joints in the outer sections were formed with... Transverse Construction Joint Design.

Joints would generally only be cross stitched where tie bars have failed or are missing and involve only non-moving joints (never on moving joints such as contraction, expansion and isolation joints).
- concrete paving workforce reference no. 3: concrete pavement joint sawing, cleaning, and sealing Overview As heavy traffic crosses a pavement joint, the slab on either side may move up and down. This can lead to subgrade pumping and ultimately pavement damage. Joints need load transfer to minimize up and down movement. Load transfer mechanisms include aggregate interlock, doweled joints…
- transverse joints are to be spaced at a maximum of 15’. dowels are required at all transverse joints unless otherwise noted in plans. DOWELS ARE REQUIRED AT ALL TRANSVERSE JOINTS UNLESS OTHERWISE NOTED IN PLANS.
- require timely sawing of the pavement to ensure that the pavement cracks at joint assemblies where intended. Contraction joints typically require both a first stage and second stage saw cut.
