ST. BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />ASPHALT PAVING 321216 - 9 <br />G. Protection: After final rolling, do not permit vehicular traffic on pavement until it has cooled <br />and hardened. <br /> <br />H. Erect barricades to protect paving from traffic until mixture has cooled enough not to become <br />marked. <br /> <br />3.8 INSTALLATION TOLERANCES <br /> <br />A. Thickness: Compact each course to produce the thickness indicated within the following <br />tolerances: <br />1. Leveling Course: ±1/2 inch (13 mm). <br />2. Surface Course: Plus 1/4 inch (6 mm), no minus. <br /> <br />B. Surface Smoothness: Compact each course to produce a surface smoothness within the <br />following tolerances as determined by using a 10-foot (3-m) straightedge applied transversely <br />or longitudinally to paved areas: <br />1. Leveling Course: 1/4 inch (6 mm). <br />2. Surface Course: 1/8 inch (3 mm). <br />3. Crowned Surfaces: Test with crowned template centered and at right angle to crown. <br />Maximum allowable variance from template is 1/4 inch (6 mm). <br /> <br />3.9 SURFACE TREATMENTS <br /> <br />A. Fog Seals: Apply fog seal at a rate of 0.10 to 0.15 gal./sq. yd. (0.45 to 0.70 L/sq. m) to <br />existing asphalt pavement and allow to cure. Lightly dust areas receiving excess fog seal with <br />a fine sand. <br /> <br />B. Slurry Seals: Apply slurry coat in a uniform thickness according to ASTM D 3910 and allow <br />to cure. <br />1. Roll slurry seal to smooth ridges and provide a uniform, smooth surface. <br />2. Slurry seal to be applied min. 30 days after completion of asphalt pavement. <br /> <br />C. Slurry seals: Apply in accordance with section 302-4 of the Reference Specification. <br /> <br />3.10 PAVEMENT MARKING <br /> <br />A. Do not apply pavement-marking paint until layout, colors, and placement have been verified <br />with Architect. <br /> <br />B. Allow paving to cure for 30 days before starting pavement marking. <br /> <br />C. Sweep and clean surface to eliminate loose material and dust. <br /> <br />D. Apply paint with mechanical equipment to produce pavement markings of dimensions <br />indicated with uniform, straight edges. Apply at manufacturer's recommended rates to provide <br />a minimum wet film thickness of 15 mils (0.4 mm). <br />1. Broadcast glass spheres uniformly into wet pavement markings at a rate of 6 lb/gal. <br />(0.72 kg/L). <br /> <br />E. Comply with paint manufacturer's maximum drying time requirements to prevent undue <br />softening of bitumen and pick-up, displacement, or discoloration of pavement marking by <br />vehicular traffic.
