The modern RPB varies its settings to fit site conditions. Place asphalt overlay. Columbus Airport, Indiana - Constructed in - 6 thick, non-reinforced, concrete taxiway - 24, square yards rubblized - Clay subgrade - Overlay: 7. The same principal applies with a pavement system prior to rubblization. Fernando Almeida. For designing a rubblized pavement, the HMA overlay pavement thickness is determined in the same way that a new asphalt pavement would be, treating the rubblized layer like a high quality base or stabilized base. Existing pavement - Any asphalt overlay must be removed bid item - Full-depth asphalt patches evaluated for soundness, replace as necessary - Partial-depth asphalt patches: removal requirements vary - Full-depth saw cuts required where rubblized concrete abuts concrete to remain in place.
