Concrete expansion joints explained Hanson UK
2021-5-11 A concrete expansion joint – or control joint – is a gap which allows the concrete to expand and contract as/when the temperature changes. It forms a break between the concrete and other parts of a structure to allow movement without causing stress, which can lead to cracking. They should be used in large concrete slabs such as foundations and concrete driveways.

CONSTRUCTION OF CONCRETE ROAD WITH
In constructing a concrete road with expansion joints the support apparatus is first placed on a roadbed in general alignment with the desired location of a particular expansion joint, self-oiling dowel bars are secured adjacent the cross members with the dowel bars resting on the support members and being aligned generally with the longitudinal axis of the road, the concrete is poured for finishing the road,

Road joints - Designing Buildings Wiki
Joints are formed in concrete slabs as part of the process of constructing rigid paving for roads. Joints are discontinuities in the pavement slab that are necessary to allow for expansion, contraction and warping. Rigid paving consists of a reinforced or unreinforced insitu concrete slab laid over a

Design and Construction of Joints for Concrete Streets
2011-9-7 Table 2 suggests joint spacings for various pavement thicknesses. Typically, for jointed plain concrete streets, the joint spacing should be 24 to 30 times the pavement thickness with a maximum spacing of 15 ft (4.5 m). It is also important to keep slabs as square as possible. Transverse joint spacing should not exceed 125% to
