How much should the contractor overlap on longitudinal runs?
The minimum overlap adopted by contractors is 100mm. If the overlap is greater than 100 mm then the contractor should ensure that the binder application is not doubled in the overlapped section. Caution is required when using cementitious binders if the overlap does not included more binder and mixing occurs in previously compacted cemented material. In this instance, the mixing should be within the working time of the cemented material.
