Roadwork: Vincent Chu Answers

Should joints of concrete kerbs be in line with the joints in concrete carriageway?

In normal practice, joints are provided in road kerbs to cater for concrete expansion and contraction.

However, the location of joints in kerbs is not arbitrary and they should match with joints in concrete carriageway. Otherwise, it is very likely that cracks may form in concrete kerbs at location of pavement joints.
