Joints are spaces between two asphalt or concrete layers, or between their layers or components, such as kerbs, manhole covers etc. These joints are either intentional or necessary for the working situation in question. Seams are contact surfaces that are created when asphalt mix is laid in lanes, alongside ...
The usual recommendation is for some form of movement joint to be created in a nonreinforced slab at a separation of approximately 30 times the slab thickness. So, for a 100mm thick slab, there should be some for of joint every 100m × 30 = 3000mm = every and, in a 150mm slab, 150 × 30 = 4500mm =
