Modular pavers in driveways to be placed on a concrete base course with a sand leveling bed. A ¾ to 1” setting bed consisting of stone dust should be applied over the concrete subbase conforming to ASTM C 33. When calculating bed levels, it is important to consider that the bricks will be compacted approximately 1/8” - ¼” into the setting bed with a plate vibrator during final steps of installation. Level setting bed with a straight edge to desired heights. Level, but do not compact. Only spread sufficient area that can be covered with Pavers the same day. Do not step in or disturb the setting bed in any manner. Place the paving bricks into position by hand, keeping joints as tight as possible. As soon as a sufficient area of bricks has been laid, the

. Do not step in or disturb the setting bed in any manner. Place the paving bricks into position by hand, keeping joints as tight as possible. As soon as a sufficient area of bricks has been laid, the bricks are compacted into the setting bed with a high frequency, low amplitude plate vibrator. Units are pressed into setting bed and compacted. Joints are then filled with sand and brick pavers are vibrated until all joints are completely filled. Excess sand is removed. The only cutting of the bricks needed is at the boundaries. Cutting should be carried out with a diamond masonry saw. The pavement can be used by normal traffic as soon as it is completed. The sand to be used as joint fill should be stabilized with an organic additive “SANDLOCK” as provided by PAVE TECH INC. or approved equal. Materials and mixing procedures as indicated in the manufacturer’s specifications. The cost for this work shall be covered under the unit price bid for Concrete Modular Paver. As directed, Aluminum paver restraints shall be utilized along planters and green areas. Materials and installation procedures as indicated in the manufacturer’s specifications. The cost for this work shall be covered under the unit price bid for paver item. On resetting work, the Contractor shall carefully remove the existing pavers, clean, and store pavers for resetting once base course work is complete.

SECTION 610 – TRAFFIC STRIPES, TRAFFIC MARKINGS, AND RUMBLE STRIPS 610.03.02 Traffic Markings Lines, Traffic Markings Symbols, and Traffic Markings Route Symbols THE SUBPART IS CHANGED TO: A. Marking Plan. At least 20 days before beginning the work, submit to the RE for approval a marking plan that includes: 1. Schedule of operations for applying traffic markings. 2. Number and type of equipment. 3. Manufacturer’s

work, submit to the RE for approval a marking plan that includes: 1. Schedule of operations for applying traffic markings. 2. Number and type of equipment. 3. Manufacturer’s recommendations for use of the materials, including mixing ratios and application temperatures. 4. Details on the means and methods for surface preparation. 5. Details on the means and methods for premarking. B. Surface Preparation. Immediately before marking the pavement surface, clean the surface of dirt, oil, grease, and foreign material, including curing compound on new concrete. Clean the surface 2 inches beyond the perimeter of the marking to be placed. HELEN AVE., LAWRENCE AVE., FLORENCE PL., AND LOWELL AVE., IMPROVEMENTS PROJECT Page 60 of 76

C. Applying Traffic Markings. Place preformed thermoplastic or hot extruded thermoplastic traffic markings on thoroughly dry surfaces and during dry weather conditions. Apply using equipment and procedures that produce markings of the specified color, width, and thickness with well-defined edges, uniform retroreflectivity, and proper bonding to the pavement. Apply the thermoplastic material as follows: 1. Preformed Thermoplastic. Melt the preformed thermoplastic tape to bond the traffic markings permanently in position according to the manufacturer’s recommendations. Meet the minimum initial retroreflectance value, as specified in 610.03.01.D for thermoplastic tape, by applying additional glass beads to the hot-wet material in a uniform pattern as necessary. 2. Extruded Thermoplastic. Uniformly heat the thermoplastic material. When the ambient and surface temperatures are at least 50 °F, apply the melted material at a temperature of between 400 and 425 °F. Extrude the thermoplastic traffic markings on the HMA or concrete pavement ensuring a thickness of 90  1 mils. Immediately after, or in conjunction with the thermoplastic extrusion, uniformly apply glass beads to the wet material at a minimum rate of 10 pounds per 100 square feet of markings. Apply glass beads by mechanical means only. D. Applying Transverse Rumble Markings. Install transverse rumble markings as follows: 1. Ensure the HMA or concrete pavement is clean and dry before applying thermoplastic materials as specified in 610.03.02.B. 2. Heat thermoplastic material as specified in 610.03.02.C.2. 3. Apply one layer of thermoplastic material on the HMA or concrete pavement surface at a thickness of 125 ± 1 mils. Then while the material is hot, apply a second layer of thermoplastic material at 125 ± 1 mils. 4. Uniformly apply glass beads as specified in 610.03.02.C.2. 5. The Contractor will ensure that there is no separation between the first and second layer of thermoplastic material before the RE’s final acceptance of transverse rumble markings. 6. The Contractor will ensure that the appropriate thickness of 125 ± 1 mils per layer of thermoplastic material is installed, any markings found by the RE to be

erse rumble markings. 6. The Contractor will ensure that the appropriate thickness of 125 ± 1 mils per layer of thermoplastic material is installed, any markings found by the RE to be thinner than 125 ± 1 mils will be removed and reinstalled by the Contractor at no additional cost to the Department. 7. The Department will make payment for transverse rumble markings by square feet under TRAFFIC MARKINGS SYMBOLS as specified in 610.04. 8. Thermoplastic material for transverse rumble markings shall be white in color. E. Performance. Ensure that the traffic markings show no fading, lifting, cracking, chipping for any reason including but not limited to traffic wear, maintenance activities including snow plowing, until Acceptance. Ensure that 60 days after application, traffic markings have a minimum retroreflectance value of: 375 millicandelas per square meter per lux for white traffic markings 250 millicandelas per square meter per lux for yellow traffic markings F. Defective work. Replace thermoplastic traffic markings that are determined by the RE before Acceptance to be defective or that are damaged during construction. Remove defective markings as specified in 610.03.08. Replace the entire area of thermoplastic traffic markings determined to be less than the required thickness, to have incorrect color or width, to have failed to bond to the pavement, or to have chipped or cracked. The minimum replacement area is an individual word or symbol, or for longitudinal lines the entire length from where the deficiency first occurs to where it no longer exists. The RE will determine initial retroreflectance as follows: Provide the RE with a Reflectometer that meets a 30 meter geometry as specified in ASTM E 1710, capable of measuring wet and dry conditions as specified in ASTM E 2176 and ASTM E 2177, and that has been certified by the manufacturer as being calibrated within the last 2 years. The RE will test the retroreflectance of traffic markings with the provided reflectometer according to the manufacturer’s recommendations. Replace traffic markings that do not meet the retroreflectance values indicated in 610.03.02.E. G. Opening to Traffic. Complete each application of thermoplastic traffic markings and allow to thoroughly dry
