Effective with the December 2018 Letting 370 2019 Standard Spec ifications Section 620 Concrete Corrugated Median and Concrete Median Nos e
620.1 Description
1.This section describes constru cting a concrete corrugated medi an or concrete median nose placed in one course on a pr epared foundation.
620.2 Materials
1.Use materials conforming to the following: Concrete ...................................................... ................................................................................................... 501 Joint filler .................................................. ................................................................................................ 415.2.3 Reinforc ement ................................................. ............................................................................................... 505
2.Furnish grade A, A-FA, A-S, A-T , A-IS, A-IP, or A-IT concrete conforming to 501 as modified in 716. Provide QMP for class II ancilla ry concrete as specified in 716.
620.3 Construction
1.The engineer will inspect concre te built under 620 for transverse cracking as specified in 415.3.17 for ancillary concrete. Repair cracke d concrete as the engineer dir ects.
2.Under the Concrete Corrugated M edian bid item, construct concr ete corrugated median including nose section, placed in one course on a prepared foundation.
3.Under the Concrete Median Blun t Nose bid item, construct a blunt concrete median nose section.
4.Under the Concrete Median Sloped Nose bid item, construct a sl oped concrete median nose section.
620.3.1 Preparing the Foundation
1.Prepare the foundation for the median by excavating to the lin es, grade, and cross-section the plans show and required for placing t he concrete. Remove and replace any soft or unsuitable material encountered with suitable material and thoroughly compact and f inish the foundation to a firm surface. Ensure the foundation is moist when placing the concrete.
620.3.2 Placing Concrete
1.If forms are required, set them to line and grade and secure i n place before placing the concrete.
2.Deposit the concrete to the pr oper depth, consolidate by spadi ng or vibrating, and strike off at the required elevation and crown. For m the required corrugations with tools and equipment appropriate for the purpose, according to the plan details.
3.If constructing the median adjacent to concrete pavement, plac e tie bars as specified for longitudinal joints in concrete pavement under 415.3.7.2 .
4.Broom finish the surface of the median unless specified otherw ise. Draw the broo m transversely across the full width of the medi an surface with adjacent strok es slightly overlapping. Perform brooming in a way that produces corrugations uniform in appearance and not greater than 1/8 inch deep. Complete the brooming befor e the concrete’s condition causes the surface to tear or become rough from the operation. Provide a finished surface free from rough or porous areas, irregularities, and depressions resulting from improper broom handling. Ensure brooms are the quality, size, and construction appropriate for the job and operated to produce a surface finish meeting the engineer’s approval.
6.Remove and dispose of all excava tion and surplus materials in the manner specified for in 205.3.12.
620.4 Measurement
1.The department will measure Conc rete Corrugated Median by the square foot acceptably completed, including the nose section.
2.The department will measure Concrete Median Blunt Nose and Con crete Median Sloped Nose by the square foot acceptably complet ed, for the nose section only.
620.5 Payment
1.The department will pay for measured quantities at the contrac t unit price under the following bid items: ITEM NUMBER DESCRIPTION UNIT 620.0100 Concrete Corrugated Median SF 620.0200 Concrete Median Blunt Nose SF
