<br />Engineer prior to start of work. The completed mixture shall be such that <br />the slurry seal mixture has proper workability and will permit traffic flow <br />within one hour after placement without the occurrence of bleeding, <br />raveling, polishing, separation or other distress, and prevent the <br />development of bleeding, raveling, polishing, separation, or other distress <br />within 30 days after its placement. <br /> <br />5. Asphalitc emulsion shall be added at a rate of between 13 to 18 percent by <br />weight of the dry aggregate. The quality of asphaltic emulsion to be used in <br />the slurry seal mixture will be determined from the design asphalt binder <br />content, as approved by the Engineer, and the asphalt solids content of the <br />asphaltic emulsion finished.. <br /> <br />6. The slurry seal mixture shall be applied to overlap the lip of gutter; this <br />overlap is not to exceed beyond two inches (2") from the lip of gutter toward <br />the face of curb. On streets that have no concrete gutter, the slurry seal <br />shall extend to the face of curb. Any application or spillage beyond this <br />two-inch limit shall be removed or cleaned up by the Contractor to the <br />satisfaction of the Engineer. Gutter spills shall be cleaned immediately. <br /> <br />7. The seal coat shall be applied in such a manner that the joint between the <br />new and existing surface is neat and uniform in appearance true to the line <br />shown on the typical cross section and established by the Engineer. <br />Roofing paper or a comparable substitute shall be used at all ends of slurry <br />seal limits to provide for a clean, neat, and straight definition of the end of <br />the slurry. <br /> <br />8. Longitudinal joints shall be at the crown of the street or at the edge of travel <br />lanes. <br /> <br />9. No excessive buildup or unsightly appearance shall be permitted on <br />longitudinal or transverse joints. Burlap drags shall be used. <br /> <br />10. Approved squeegees shall be used to spread slurry in non-accessible <br />areas to the slurry mixer. Care shall be exercised in leaving no unsightly <br />appearance from hand work. <br /> <br />11. At any time the quality of the mix or workmanship is not to the satisfaction <br />of the Engineer, the job shall be discontinued until a correction is made <br />which is satisfactory to the Engineer. <br /> <br />12. A sand blotter shall be spread at selected intersections and where required <br />by the Engineer, to accommodate pedestrian or vehicular traffic until slurry <br />sets. Sand blotter shall be placed by broadcasting slurry aggregate lightly <br />so not to cause any displacement of wet slurry seal. Sand blotters at <br />intersections shall be swept within 24 hours of placement or sooner if <br />directed by the Engineer. <br /> <br />13. Any traffic control devices (barricades, cones, or signs) which are moved in <br />the process of applying the slurry are to be returned to a proper position by <br />the Contractor as soon as possible. <br /> <br />14. Wheel tracks, foot prints, and other undesired markings in the slurry seal <br />shall be repaired to the satisfaction of the Engineer. <br /> <br />15. Treated areas will be allowed to cure until such time as the Engineer <br />permits their opening to traffic. <br /> <br />SLURRY SEAL <br /> <br />02540-5 <br />
