Cement Stabilized Base & Chipseal Why Tagus Avenue?

HIST ORY – CR 54 1. Higher volume gravel road 2. Required frequent blading to keep smooth 3. Annual dust control application 4. Washboards 5. Poor soils, frequent frost boils

GOAL S F OR CR 54 And othe r hig he r volume g ra ve l roa ds • Dust Free Road • Washboard Free • Stand up to Agricultural Traffic • Cost Effective
