274 The concrete shall be placed directly ag ainst the existing pavement edges, which shall be free from all foreign materials. Th e surface of the concrete widening shall be 120 at the same elevation as the top of the existing concrete base. Materials and construction requirements shall be in accordance with the applicable requirements of 502, except the following: (a) coarse aggregate shall be Class A or higher;
b.joints shall be sawed in one pass and not sealed. Transverse joints constructed in the widening shall be aligned with existing transverse joints or cracks; 130
c.tining is not required;
d.shoulder corrugations are not required;
e.pavement smoothness shall be controlled by a 16 ft straightedge; and
f.utilization of the Department provided spreadsheet is not required. When the widening is closed to traffic prior to placing the overlay, liquid 140 membrane compounds shall not be used and an alternative curing option shall be used. Tack coat in accordance with 406 may be used as a curing option.
305.06 Method of Measurement
Compacted aggregate will be measured by the ton in accordance with 109.01(b) for the type specified. Retrofit load transf er will be measured in accordance with
507.09 Surface milling will be measured in accordance with 306.10. PCC base, PCC
base patching, and widening with PCC base will be measured by the square yard of the thickness specified. The area of PCC will be the planned width of the base, patching, or widening multiplied by the measured length, or as directed in writing. The 150 planned width of the base, patching and widening will be as shown on the typical cross-sections of the plans. Rubblized PCCP will be measured by the square yard of rubblized pavement.
305.07 Basis of Payment
The accepted quantities of compacted aggregate will be paid for in accordance with 303.10, for the type specified, complete in place. Retrofit load transfer will be paid for in accordance with 507.10. Surface milling 160 will be paid for in accordance with 306.11. PCC base, PCC base patching, and widening with PCC base will be paid for at the contract unit price by the square yard of the thickness specified. 305.06 Rubblized PCCP will be paid for at the contract unit price per square yard for rubblized pavement. Payment will be made under: 170 Pay Item Pay Unit Symbol PCC Base, __________ in. ........................................................ SYS thickness PCC Base Patching, __________ in. ......................................... SYS thickness Rubblizing PCCP ...................................................................... SYS Widening with PCC Base, __________ in. ............................... SYS thickness If PCC base is found to be deficient in thickness, price adjustments in accordance with 502.23 will be determined.
