protect pavement, including edges, to prevent damage to the pavement. If the Contractor ’s hauling operations cause damage, the Contractor must repair the damage at no additional cost to the Department.
5.Overloads Exceeding Legal Limits by 50% On or Cross ing Pavements. The Engineer may allow loads that exceed the legal load limit by 50 % or more to cross existing concrete pavements at designated locations under the following conditions:
a.The Contractor places transverse joint saw cuts in the pavement and uses painted lines to define the crossing area (approximately 50 feet wide);
b.The Contractor maintains traffic on the pavement during hauling and reconstruction, as approved by the Engineer; and
c.After completing hauling with overloads, the Contractor must remo ve the pavement between the two saw cuts and replace the pavement with new pavement of the same type and design as the original pavement. If traveling across existing or new HMA pavements with loads that exceed the legal load limit by 50% or more, the Contractor must remove and replace the crossing area to the required surface tolerances, as directed by the Engineer. If the Contractor crosses existing pavements while hauling material from sources other than Department -designated sources, the Contractor must perform repair and restoration work as consideration for permission to haul with overloaded wheels or axles at no additional cost to the Department. If the Contractor crosses existing pavements while hauling material from a Department -designated borrow area, the Department will pay for the removal and replacement of pavement, if directed by the Engineer, at the contract unit price for required items of work. 104.12. Approval for the Use of the Right -of-Way The proposed right -of-way use must be directly related to the operations of the project under contract. The Contractor may use Department -owned right-of-way to perform the w ork if prior written approval is given by the Engineer. Additional restrictions regarding the use of right -of-way may exist in the contract. The use of right -of-way in wetlands and floodplains or the crossing of water courses by construction equipment is prohibited. MDOT Standard Specifications for Construction Section 104
