CoDOT TY-4 (Key-way)
Curb is extruded over a 1.5-2" Deep x 5" Wide Keyway with tack applied for asphalt paving (adhesive for concrete). We use a low-slump 4500 psi fiber reinforced Class B Mix. Carbon Dioxide is reduced 44% on new projects and 73% for retrofitting applications.
CDOT TY 6 Sec. M Erosion Curb
Colorado's TY 6 Leader
We have installed tens of thousands of feet of CDOT TY 6 Curbing throughout Colorado for 30 years. In fact, we developed the means to extrude under and behind the face of existing guardrail. This allows guardrail to be installed early, protecting motorists and adding flexibility to tight construction schedules.
We strictly comply to NCHRP Report 537 and CDOT specifications to keep the curb behind the guardrail face, with proper slope and height for motorist safety and durability. If requested/required we can mill a keyway (prior to guardrail install) and slip-form the curb at a later date.
Did you know?
Improperly installed curb in conjunction with guardrail can cause the vaulting, snagging and tripping of vehicles. Regrettably, thousands of injuries and hundreds of fatalities a attributed to improperly installed curbing with guardrail annually.
