Include identification of joints with dowels and with tie-bars. Identify pavements or slabs that are reinforced and the reinforcement. Include location
21、of each random crack where repairs are needed.2. Show approximate location, length and width of each spall and location and size (usually average diameter) of each popout. Dimensions of spalls and popouts need not be to scale. Identify by legend and symbol whether spall repair needed is approximatel
22、y rectangular or pentagonal (triangular spall). Specifically detail any special or unusual shapes or partial depth repairs.3. If required spall repairs are extensive, provide a schedule showing scope of work and quantities for bid purposes in addition to the location plans. Identify feature areas wh
23、ere spalls or groups of spalls are located, area of spall repairs in square meter square feet, location and number or area of popouts, and other PCC pavement repairs which may be a part of the contract.4. Provide details of spall and popout repairs. Refer to UFC 3-270-03 and AASHTO SDDP-1 for sugges

Sounding may be done with a steel hammer, steel rod, or other suitable means for locating hollows. It is not unusual for delamination in a sp
26、all area to extend well beyond that visually obvious. Each previous partial depth patch should also be sounded for present condition.*1.1 UNIT PRICES*NOTE: When lump-sum payment is used, delete this paragraph .
