FHWA TECHNICAL iiDVISORY T 5080.17 July 14, 1994 ATT~Pr’THF?CT 3 5. 6. 7. 8. 9. 10. 11. SUBBASE THICKNESS TEST After trimming, is the thickness of the subbase being checked? CRAINAGF, Is the subgrade being kept drained during all operations? Are all berms of earth deposited adjacent to the grade being kept drained by cutting lateral ditches through the berms? LUG SYSTEMS (CONTINUOUSLY REINFORCED) If concrete lug end anchorages are specified, are they staked and checked for dimensions and re-bar placement as shown in the plans? Are they constructed of Structural Concrete at least 24 hours prior to pavement construction? LONGITUDINAJ, JOINT KEYWAY AND BARS Are the beginning and ending stations marked where adjacent curb, median, or pavement will.necessitate the placement of keyway and/or bars in the edge of the proposed pavement? SUPERELEVATION STAKING Are the plan curb data examined for all curves to determine where to stake the beginning and ending stations for a&l superelevation transitions? TEMPERATZTRE TJMITATIONS Does the outside air temperature in the shade meet State specifications? Does the temperature of the concrete meet State smcifications at the time of placement? REINFORCEMENT TAPPING Are the locations and lengths of lap for bar or fabric reinforcement in conformance with the specifications. Are all bar and fabric laps being tied? 3.10.34
12. 13. 14. TRUCK REGUIREMENTS FHWA TECHNICAL ADVISORY T 5080.17 July 14, 1994 ATTACHMENT 3 Is all concrete in a stationary mixer being deposited within 30 minutes when hauled in non-agitating trucks and within 90 minutes when hauled in agitator trucks? Is transit mixed concrete being delivered and deposited within 90 minutes from the time stamped on the ticket? If the contractor plans to use previously placed -pavement as.a haul road, are the truck weights checked to assure compliance with maximum weights permitted by State Law? REINFORCEMENT PLACEMENT IS the reinforcement being placed in accordance with one of the following methods? Method A - After the full depth concrete is struck off 'the reinforcement should be placed into the concrete to the .required depth by mechanical means. Method B - The.reinforcement should be supported on the prepared subbase by approved chairs having sand plates. Method C - When the concrete is being placed in two layers the reinforcement should be laid full length on the struck-off bottom layer of concrete in its final position without further manipulation. (Cover within 30 minutes.) The depth of the first lift is 2/3 the depth of the pavement. Method Q - The reinforcement may be placed in the pavement using a method which does not require transverse steel or support chairs for support of the longitudinal steel. Tie bars at longitudinal joints are still required. S OF FORM TYPE PAVING .- - Is all of the required concrete finishing equipment on the job and in acceptable working condition? Are the following sequences for form type paving being properly followed: 3.10.35
