Whenever it is necessary to break through existing street pavement for excavation purposes, the pavement and the base shall be removed to at least six inches beyond the outer limits of the subgrade that is to be disturbed in order to prevent settlement, so that a six-inch shoulder of undisturbed material shall be provided in each side of the excavated trench. In concrete pavement the face of the remaining pavement shall be approximately vertical and the concrete pavement shall be sawed in such a manner as not to leave ragged edges. Asphalt pavement shall be scored or otherwise cut in a straight line. Brick pavement shall be removed in a near rectangular or square pattern as the pavement will permit.
