807 - PAINTED PAVEMENT MARKING
800-31 f. Replacement of Unsatisf actory Pavement Marking. Apply pavement markings straight and close to
the intended alignment w ithout abrupt changes that result in an unacceptab le appearance. Lines that deviate laterally from the intended alignment more than 2 inches in 200 feet may be rejected. Remove and replace pavement markings that have: drag marks, gashes, gouges, foreign covering, discolored areas, areas that have failed to solidify, improper adhesion, improper width, length or thickness, areas that present a ragged appearance, areas that do not present sharply defined edges, areas with abrupt unintended changes in alignment. Do not meet TABLE 807-1 . TABLE 807-1: PAINTED PAVEMENT MARKING MINIMUM RETROREFLECTIVITY REQUIREMENTS TYPE OF MATERIAL COLOR millicandelas/sq m/lux* (minimum) (Initial) Waterborne Traffic Paint White 250 Yellow 175 NOTE: Provide an acceptable 100-foot retrorefle ctometer to use on the project which will remain the property of the Contractor. In the presence of the Engineer, measure the retroreflectivity between 12 hours and 7 days after the applicati on of all pavement markings. Take a minimum of 5 randomly sp aced readings per color line every 1 mile. The Engineer will average all of the readings for each color line within the 1 mile section to determine the retroreflectivity. Removal and replacement of unsatisfactory pavement marking will be at the Contractor’s expense. 807.4 MEASUREMENT AND PAYMENT The Engineer will measure the painted pavement marking by the linear foot for the various widths and classes. The Engineer will measure each symbol. Payment for "Pavement Marking (Paint)" and "Pavemen t Marking Symbol (Paint) (W hite)" at the contract unit prices will be full compen sation for the specified work. 808 - REMOVAL OF EXISTING PAVEMENT MARKINGS

a.Removal of Existing Stripes and Symbols. Completely remove the existing pavement markings and symbols without damaging the asphalt or concrete pavement surface or longitudinal and transverse joints. Waterblasting will only be allowed for removal of markings on concrete surfaces. As th e work progresses, remove all material deposited on the pavement as a result of the removal operations. When blast cleaning within 10 feet of the traveling public, continuously remove all residue and dust. When replacement of the removed existing markings is a part of the Contract Documents, follow the manufacturer’s requirements for the new pavement markings as to the method of removal of the existing markings, or surface preparation requirements.
b.Removal of Plowable Raised Markers. If the plowable raised markers ar e to be reinstalled, remove them without damaging. All damaged plowable raised markers will be repl aced at the Contractor’s expense.
c.Repair. Use methods approved by the Engineer to repair all pavement damaged during the pavement marking removal operations. 808.4 MEASUREMENT AND PAYMENT The Engineer will measure the removal of each skip and solid line of existin g pavement marking by the linear foot. NOTE: Removal of temporary pavement marking is subsidiary to the temporary pavement marking bid item. The Engineer will measure each pl owable raised marker removed. The Engineer will not measure removal of existing pavement marking symbols for payment. Payment for "Pavement Marking Removal" and "Pav ement Marking Removal (Plo wable Raised Marker)" at the contract unit prices is full compensation for the specified work. 809 - CONCRETE SAFETY BARRIER
800-33 Section 809
CONCRETE SAFETY BARRIER 809.1 DESCRIPTION Construct permanent cast-in-place concrete safety ba rrier according to the Contr act Documents. Place and remove temporary precast concrete safety ba rrier according to Contract Documents. B I D I T E M S U N I T S Concrete Safety Barrier (*) Linear Foot Concrete Safety Barrier (*) (Temporary) Linear Foot Concrete Safety Barrier (*) (Temporary - Installation Only) Linear Foot Concrete Safety Barrier (*) (Temporary - Relocate) Linear Foot *Type 809.2 MATERIALS
a.Permanent Cast-in-Pla ce Concrete Safety Barrier. Provide materials that comply with the Contract Documents and DIVISIONS 1000 - 2500 . The Engineer will visually inspect the completed installation before making final acceptance.
b.Temporary Precast Concrete Safety Barrier. Provide certification (prepared by the manufacturer or Contractor) that the temporary precast concrete safety barrier complies with the requirements on the Contract Documents. Provide either new or used , temporary precast concrete safety ba rrier. The Engineer will accept, either new or used, temporary precast concrete safety barrier upon acceptance of the provided certification, and visual inspection of the delivered and in stalled temporary precast concrete safety barrier on the project.
c.Median Filler Material. Provide SB-3 for median filler material that complies with DIVISION 1100 . 809.3 CONSTRUCTION REQUIREMENTS
a.Permanent Cast-in-Pla ce Concrete Safety Barrier. Construct the cast-in-pl ace concrete safety barrier as shown in the Contract Documents and according to DIVISION 700 . Place median filler material as indi cated in the Contract Documents.
b.Temporary Precast Concrete Safety Barrier. Install and remove the precas t concrete safety barrier as required. Do not use temporary precast c oncrete safety barrier that is damaged or deteriorated. Erect the temporary precast concrete safety barrier as shown in the Contract Documents. The tempor ary precast concrete safety barrier will remain the property of the Contractor, unless shown otherwise in the Contract Documents. If the Contract Documents require installation only, tr ansport from the designated stockpile, install and return the temporary precast concrete safety barrier to the designated location. Relocate the temporary precast concrete safety barrier as shown in the Contract Documents, or as directed by the Engineer. Remove and replace all sections of temporary preca st concrete safety barrier damaged during or after placement. Remove, clean or replace temporary precast concre te safety barrier (including barrier delineators) that has deteriorated to the point of being non-effective. 809.4 MEASUREMENT AND PAYMENT
a.Permanent Cast-in-Place Concrete Safety Barrier. The Engineer will measure cast-in-place concrete safety barrier by the linear foot along the centerline of the barrier. Payment for "Concrete Safety Barrie r (*)" at the contract unit prices is full compensation for the specified work. Median filler material is subsidiary to other items in the contract. 809 - CONCRETE SAFETY BARRIER
800-34 b. Temporary Precast Concrete Safety Barrier. The Engineer will measure the precast concrete safety
barrier by the linear foot (number of sections times the nominal section lengt h). A precast concrete safety barrier transition section (regardless of actual length) will be me asured as a nominal section length of temporary precast concrete safety barrier. The quantity of precast concrete safety barrier measur ed for payment is the maximum quantity required on the project at any one time, plus any replacement sections measured for payment, and is paid fo r as Concrete Safety Barrier (*) (Temporary). Each section of temporary precast concrete safety barrier will be measur ed for payment when put in use on the project. Sections of temporary precast concrete safety barrier used to replace sec tions damaged by traffic while in use will be measured for payment and paid as Concrete Safety Barrier (*) (Tempor ary-Installation Only) when put in use on the project. When provided by the Cont ractor, sections of temporary precast conc rete safety barrier used to replace deteriorated sections or sections damaged through negligen ce of the Contractor are not measured for payment. When stage construction requires that the precast concre te safety barrier be moved from its initial position to an alternate position, the Engineer will measure the relocated barrier by the linear foot (number of sections times the nominal section length). The barrier will be measured for payment in each relocated position the barrier is placed and is paid as Concrete Safety Barrier (* ) (Temporary-Relocate). If the stage c onstruction requires that the barrier be removed from the project to a storage location, and returned to the project during a subse quent construction stage, each movement of the barrier will be considered a relocation. Removal of the precast concrete safety barrier, when no longer required on the proj ect, is not measured for separate payment. Payment for "Concrete Safety Barrier (*) (Temporary)", "Concrete Safety Barrier (*) (Temporary-Installation Only)", and "Concrete Safety Barrier (*) (Temporary-Relocate)" at the contract unit prices is full compensation for the specified work. The quantities shown in the Contract Documents for the various items of temporary precast concrete safety barrier are estimated. The contract unit prices will not be adjusted, regardless of overruns or underruns.
