704.1 Construction Inspection for Sec 704
This work consists of removing deteriorated concrete, preparing the repair site, forming where required, placing and finishing new concrete or qualified special mortar and applying epoxy in the required areas.
The types of repair are:
- Half-Sole Repair
- Deck Repair With Void Tube Replacement
- If the contractor can adequately patch an exposed void tube, then the entire repair is considered either half-sole or monolithic deck repair.
- Full Depth Repair
- Modified Deck Repair
- Superstructure Repair (Unformed)
- Slab Edge Repair
- Substructure Repair (Formed)
- Substructure Repair (Unformed)
- Epoxy Sealing
- Monolithic Deck Repair
- Shallow Deck Repair
Refer to Sec 704.
Excavator hydraulic hammers shall not be used for removal of deck concrete unless otherwise specified on the bridge plans.
704.2 Materials Inspection for Sec 704
For more information regarding Rapid Set Concrete Patching Material, refer to JSP 02-01.
Two lists of qualified rapid set concrete patching materials are maintained by Construction Materials. One list shows approved horizontal patching materials and the other list is for vertical and overhead patching materials.
704.3 Laboratory Testing for Sec 704
704.3.1 Scope
This guidance establishes procedures for Laboratory testing and reporting concrete cylinders representing Class X Concrete.
704.3.2 Procedure
Concrete cylinders shall be tested for compressive strength according to AASHTO T 22. Test results and calculations shall be recorded through AASHTOWARE Project (AWP).
704.3.3 Sample Record
The sample record shall be completed in SiteManager, as described in AWP MA Sample Record, General. Appropriate remarks, as described in EPG 106.20 Reporting, are to be included in the remarks to clarify conditions of acceptance or rejection. Test results shall be reported on the appropriate templates under the Tests tab.
