A method for patching pavement, the method comprising:

• providing a precast pavement panel having:
• a first end, a second end, a top surface, and a bottom surface;
• a first opening defined at the first end of the precast pavement panel such that the first opening opens from at least one of the first end, the bottom surface, and the top surface of the precast pavement panel;
• a cross member that extends between the first end and the second end of the precast pavement panel;
• and
• a fastening member having a first portion that is anchored within the precast pavement panel and a second portion that extends from the first portion and into the first opening so as to terminate within the first opening;
• placing the precast pavement panel next to a piece of continuously reinforced concrete pavement having a first anchor member having a first part that is anchored within the piece of continuously reinforced concrete pavement and having a second part that extends from a first face of the piece of continuously reinforced concrete pavement;
• and
• coupling the precast pavement panel with the piece of continuously reinforced concrete pavement such that the second part of the first anchor member extends from the piece of continuously reinforced concrete pavement into the first opening so that a length of the second portion of the fastening member and a length of the second part of the first anchor member run adjacent to each other within the first opening so as to be configured pass at least one of a tension force and a compression force from the piece of continuously reinforced concrete pavement to the cross member.

• and
• a fastening member having a first portion that is anchored within the precast pavement panel and a second portion that extends from the first portion into the first opening, wherein the second portion comprises a first enlarged head that is disposed within the first opening, adjacent to the first end of the precast pavement panel;
• obtaining a piece of continuously reinforced concrete pavement having a first anchor member that is anchored within the piece of continuously reinforced concrete pavement and that extends from a first face of the piece of continuously reinforced concrete pavement;
• aligning the first end of the precast pavement panel with the first face of the piece of continuously reinforced concrete pavement such that a portion of the first anchor member extends from the piece of continuously reinforced concrete pavement into the first opening and runs adjacent to the second portion of the fastening member, wherein the portion of the first anchor member that extends from the piece of continuously reinforced concrete pavement into the first opening comprises a second enlarged head that is disposed within the first opening, farther from the first end of the precast panel pavement than is the first enlarged head such that the first enlarged head is configured to direct a shear force in a first direction and the second enlarged head is configured to direct an opposing shear force in a second direction that overlaps with the first direction;
• and
• applying a binder into the first opening to bind the precast pavement panel with the piece of continuously reinforced concrete pavement.

A road patch system comprising:

• a precast pavement panel having:
• a first end, a second end, a first surface, and a second surface, the second surface being opposite to the first surface and the second end being substantially opposite to the first end, with at least one of the first surface and the second surface comprising a first driving surface for contacting and supporting traffic;
• a cross member that extends between the first end and the second end of the precast pavement panel;
• a first elongated opening that opens from the first surface and the first end of the precast pavement panel, the first elongated opening having a first expanded portion;
• and
• a first strengthening member and a second strengthening member that are each shorter than the cross member, wherein the first strengthening member extends along a first side of the first elongated opening, and wherein the second strengthening member extends along a second side of the first opening;
• a piece of continuously reinforced concrete pavement having:
• a first side, a first face, and a second face, with the first face of the continuously reinforced concrete pavement and the first end of the precast pavement panel forming a transverse joint that runs transverse to a length between the first end and the second end of the precast pavement panel, and with at least one of the first face and the second face comprising the driving surface;
• and
• a second elongated opening that opens from the first side and the first face of the piece of pavement, the second elongated opening having a second expanded portion;
• and
• a double headed anchor that is disposed in the first and second elongated openings so as to extend across the transverse joint and such that a first head of the double headed anchor is disposed in the first expanded portion and a second head of the double headed anchor is disposed in the second expanded portion.
