Section 2304.  Detour Pavement

2304.01     description.

Furnish and place a PCC or HMA surface to carry traffic during construction of permanent pavement.

2304.02     materials.

Use PCC or HMA for the detour pavement. Meet the following requirements.

A.    PCC Portland Cement Concrete Option.

1.     Meet the requirements of Section 2301 for Class A PCC Pavement. Use Class 2 durability coarse aggregate, or better, as defined in Article 4115.04.

2.     For median crossovers, meet the requirements of Section 2301 for Class C PCC Pavement. Use Class 3 durability coarse aggregate, or better, as defined in Article 4115.04.

3.     For detour pavement left in place, meet requirements of Section 2301 for Class C PCC Pavement. Use Class 3 durability aggregate, or better, as defined in Article 4115.04.

B.    HMA Hot Mix Asphalt Option.

Design a mixture per Materials I.M. 510 for the following:

1.     For detour pavements or median crossovers on interstates and multi-lane primary highways, use a 10,000,000 ESAL High Traffic (HT) surface or intermediate mixture, with PG 64-22 asphalt binder. The surface lift requires L-4 friction aggregate.

2.     For detour pavements on all other primary highways, use a 3,000,000 ESAL High Traffic (HT) surface or intermediate mixture with a PG 64-22 asphalt binder.

3.     For detour pavements on non-primary projects use a 1,000,000 ESAL Standard Traffic (ST) surface or intermediate mixture with a PG 64-22 asphalt binder.

2304.03     construction.

Earthwork quantities are based on the PCC option and will not be adjusted for additional HMA depth. Additional cut material may be used as earth shoulder construction.

A.    PCC Option.

1.     Meet the requirements of Section 2301. Transverse joints, center tie bars, and sealing of the center longitudinal joint are not required.

2.     Do not apply Article 2301.03, H, 4, b, unless stated otherwise in the contract documents.

3.     Apply Article 2316.02, A, 7.

B.    HMA Option.

Meet the requirements of Article 2303.03, E.

2304.04     method of measurement.

Detour Pavement constructed, in square yards, will be the quantity shown in the contract documents.

2304.05     basis of payment.

A.    Payment for Detour Pavement will be the contract unit price per square yard.

B.    Payment is full compensation for furnishing material, equipment, and labor to construct the detour pavement in accordance with the contract documents.

C.    Payment for detour pavement removal will be according to Section 2510.
