Pavement markings required as part of an entrance design shall be in accordance with DE MUTCD requirements. Type III subdivision streets shall have a centerline and edge line striping in accordance with DE MUTCD guidelines.
When pavement markings are to change on existing roadways, asphalt/pavement milling and overlay is normally performed to provide a clean surface for proposed pavement markings to be installed. A secondary option is to remove the existing pavement markings prior to installing the proposed pavement markings. Removal of pavement striping shall be performed using shot/abrasive grit or hydro-blasting. Grinding will not be permitted. The contractor's method must be approved by DelDOT prior to work beginning. Scarring of the road surface shall be repaired, but DelDOT must approve the repair method prior to work commencing. Limits of repair will be determined by DelDOT. Depending on the severity of the scarring, the Developer may be required to mill (typically to a depth of 2") and overlay the section, across full lane width(s). If the scarring is minor, the restoration may be limited to applying flat black paint or asphalt sealer to cover any exposed aggregate. If scarring isn't severe but the removal creates shadow lines or ghost lines, the repair may not require milling and paving but the contractor will be required to apply flat black paint or asphalt sealer to the full lane width as directed by DelDOT. When the project is accepted, the Developer will be required to warranty the pavement and any repairs that were implemented where using shot/abrasive grit or hydro-blasting to remove pavement striping. The warranty period following acceptance of the project shall be 3 years.
