Table 608.01 Material Requirements Applicable Materials Section Concrete ...................................................... 1002 Preformed Join t Filler .................................. 1015 Reinforcing St eel ......................................... 1020, 1022, 1023
608.03 Construction Methods
1.Construction shall be as described in Subsection 603.03.
608.04 Method of Measurement
1.Concrete island noses cons tructed on other than new pavement slabs will be measured by the each. The concrete island noses will not be measured on new pavement.
2.Removal of pavement for the pl acement of concrete island nose will be measured in square yards (square meters).
608.05 Basis of Payment
1.P a y I t e m P a y U n i t Concrete _____ Island Nose Each (ea)
2.Removal of pavement and surfacing will be paid for in accordance with Section 203.
3.Island noses constructed on ne w pavement slabs will be subsidiary to the pavement.
4.a. The 28-day compressive stre ngth of each day's production will be determined from cyli nder strength tests.
b.Payment will be reduced by the amount described in Table 603.03.
c.(1) If the 28 day compressive strength fails, the Contractor has the option to take 3 core samples, at no additional cost to the Department, and under the supervisi on of the Engineer. The average compressive strength of these cores wi ll be used to determine the actual 28- day compressive strength of each day's production.
2.Cores shall be taken and tested within seven (7) days of being notified of the strength deficiency.
3.The Engineer will select the site where the cores will be taken.
5.Payment is full compensation for all work described in this Section. - 437 - SECTION 609 -- CONCRETE DRIVEWAYS
