Traffic Cones

Traffic cones are typically used to keep traffic routed around the seal coat work area as shown in Figure 8‑1. Traffic cone placement must be checked to ensure:
  • Sight distance is adequate prior to lane closure
  • Proper spacing and taper lengths
  • Cones are placed past the distance of the first asphalt shot
  • Cones are placed outside the operating path of the asphalt distributor and aggregate spreader.
