In the latter cases, the concrete lanes approaching the intersection may begin 200 to 400 ft (60 to 120 m) from the intersection’s physical area, while lanes leaving the intersection terminate about 50 ft (15 m) beyond the physical area.

Some intersection improvements require additional concrete lanes next to existing concrete pavement or curb and gutter. For these improvements it is essential to place transverse contraction joints (Type A-1 or A-2, Figure 3 on page 6) to match any existing joints or cracks in the existing pavement (Figure 19).

Tips for Reconstructing Concrete Intersections Concrete ...

Feb 01, 1996  Jointing concrete intersections is crucial to the long-term performance of the pavement. Be sure that joints are sawed or formed at all drainage and other structures. Slabs should also be kept relatively square to prevent cracking, with a length-to-width ratio of no more than 1.5. For typical intersections, use a maximum joint spacing of 24 to ...

Tips for Reconstructing Concrete Intersections

By basing intersection opening on a target concrete compre s s i v e s t r ength, rather than a time inter-val, contractors can often open new concrete intersections to t r affic faster.
