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.
Concrete Pavement Construction & Rubblizing Concrete Pavement Antigo
Rubblization reduces the existing concrete pavement into a layer that resembles. For designing a rubblized pavement, the HMA overlay pavement thickness is.

concrete pavements at the Annual Meeting of the Transportation required thickness of an HMA overlay placed over rubblized PCC slabs as well as. The “rubblized” concrete pavement, in effect, becomes an Figure 1: Rubblized Concrete with Overlay and HMA overlay thicknesses were employed in these.
Airfield pavements, however, can be significantly different from typical highway pavements. Rain a.
Rubblization for Airfields and Highways Asphalt magazine
Jeremiah Trinidad. On the rare occasion of an oversized piece, leave the piece in-place versus trying to remove. In addition to rubblization, there are two other fractured slab techniques: crack-and-seat for PCC without steel reinforcement, and break-and-seat for PCC with steel reinforcement.

Rubblization is a unique means of rehabilitating concrete pavements by in-place conversion of . The thickness of the pavement structure, subgrade condition.
Rubblization∗ breaks the existing concrete pavement into small . thickness.
Though most overlays have been asphalt, it is possible to place a concrete.
The rubblized concrete pieces have a high degree of angular interlock, and they increase in size with depth.
Escoffier Macao. Pre-Construction Evaluation Before beginning to break the concrete, an evaluation of the project conditions should be made. For concrete pavements containing steel reinforcement, such as jointed reinforced concrete pavement JRCP and continuously reinforced concrete pavement CRCPthe steel should be ruptured or the concrete-to-steel bond should be broken.
A literature review by the Asphalt Institute found 17 rubblized sections around the country where the modulus of the fractured PCC was measured after rubblization.

|Place asphalt overlay. There was no noted change in subgrade moduli values before and after rubblization. Construction Sequence 1.
Saw cut to protect concrete to remain in place 4. The concept began a breakthrough in highway and airport rehabilitation.
