00545.00 498 Section 00545 - Reinforced Concrete Bridge Approach Slabs
Description
00545. 00 Scope - This Work consists of constructing reinforced portland cement concrete bridge approach slabs at the locations shown or as directed, and in close conformity to the lines, grades and dimensions shown or established.
Materials
00545.10Materials - Furnish Materials meeting the requirements of Section 00530 and
• Furnish Class HPC45 00 concrete for approach slabs, unless shown otherwise. When pipe under approach slabs are shown, provide one of following types: Class V reinforced concrete pipe meeting the requirements of 02410. 10(g) Schedule 80 polyvinyl chloride (PVC) pipe meeting the requirements of ASTM D1785 Type PSM polyvinyl chloride (PVC) sewer pipe meeting the requirements of ASTM D3034 SDR 26 Grade A or B galvanized steel pipe, STD weight class minimum, meeting the requirements of ASTM A53, hot -dip galvanized according to AASHTO M 111 ( ASTM A123) For pipe under approach slabs, provide pipe bedding, pipe zone material , and backfill meeting the requirements of 00405.12, 00405.13, and 00405.14. Provide granular structure backfill meeting the requirements of 00510.13.
00545.15Quality Control - Provide quality control according to Section 00165
Labor
00545.30Quality Control Personnel - Provide technicians having CEBT, CDT, and CSTT technical
certifications.
Construction
00545.40General - Perform Work according to Section 00530 and Section 00540 except as
modified by this Section.
00545.41Earthwork - Remove Pavement and Subgrade according to Section 00310 and
Section 00330.
00545.42Surface Finish - For approach slabs with an asphalt concrete wearing surface, a finishing
machine and roadway texturing are not required. For approach slabs without an asphalt concrete wearing surface, texture the approach slab roadway surface by sawcutting according to 00540.50(c). Perform sawcutting on approach slabs no sooner than 14 D ays after the approa ch slabs are cast.
00545.43Curing - Cure concrete according to 00540.51(a)
00545.90 499 00545.44 Expansion Joints - Construct expansion joints as shown, according to Section 00585, and as follows:
• Install armored corners for strip seal joints in preformed blockouts a minimum of 14 D ays after the bridge deck and approach slabs are cast. Set the joint opening as shown. Support the armored corners securely in position before placing concrete in the j oint blockout. • Place compression joint seals or poured sealant joint seals a minimum of 14 D ays after the bridge deck and approach slabs are cast. • Place asphaltic plug joints a minimum of 14 Days after the approach slabs are cast and after final paving is complete.
00545.45Pipes under Approach Slabs - Install pipes under approach slabs for future utilities as
shown and according to Section 00445.
00545.46AC Paving - Compact AC abutting approach slabs according to Section 00744 and
Section 00745, as applicable.
00545.47Bridge Rails - Construct bridge rails on approach slabs as shown and according
to Section 00587.
Measurement
00545.80Measurement - The quantities of reinforced concrete bridge approach slabs will be
measured on the area basis. The area will be determined by surface measurement of the width and length of each separately constructed approach slab.
Surface texturing by sawcutting will be measured according to 00540.80. Expansion joints at approach slabs will be measured according to 00585.80.
Bridge rails on approach slabs will be measured according to 00587.80.
Payment
00545.90Payment - The accepted quantities of reinforced concrete bridge approach slabs will be
paid for at the Contract unit price, per square yard, for the item "Reinforced Concrete Bridge Approach Slabs".
Payment will be payment in full for furnishing and placing all Materials, and for furnishing all Equipment , labor, and Incidentals necessary to complete the Work as specified.
Surface texturing by sawcutting will be paid for according to 00540.90.
Expansion joints at approach slabs will be paid for according to 00585.90
Bridge rails on approach slabs will be paid for according to 00587.90.
No separate or additional payment will be made for:
• sawcutting and filling the joint in the wearing surface at the roadway end furnishing and placing pipe under the approach slabs for future utilities extra thickness of approach slab as shown required stage construction, including splices
