deteriorated asphalt pavements to be recycled and stabilized with an additive, creating a new base that will provide an excellent foundation for long-term pavement performance. The principal stabilizing additives in use today for FDR are cement, asphalt emulsion, foamed asphalt, and lime/fly-ash. This paper will briefly discuss the

ments, cement-recycled asphalt and base, and other names. These specifications are intended to serve as a guide to format and content for normal soil-cement construction. Most projects have special features or requirements that should be incorporated in the project documents. 2. MATERIALS

What is cement base pavement?

with Portland cement stabilization. FDR is the in-situ pulverization of the asphalt surface layer and a portion of the underlying base course. Cement stabilization is not always used in conjunction with FDR but should be considered when the strength or durability of the existing materials is poor.

Asphalt stabilization results in more flexibility, compared to other base course materials and chemical stabilizers, and can be used alongside other additives. Reclaimer/stabilizers can be used both as a recycler, to pulverize asphalt surfaces and base layers and mix in new binders, but also as a soil stabilizer, to mix in lime, cement and ...

Many entities currently use recycled asphalt pavement (RAP) and other aggregates as base material, temporary haul roads, and, in the case of RAP, hot mix asphalt construction. Several states currently allow the use of RAP combined with cement for a stabilized base course under both asphalt and concrete pavements.

Once the stabilized base section is completed, the CCPR process will take the stockpiled asphalt grindings, crush them, and mix them with an engineered emulsion to produce a recycled asphalt that will be paved as the base course asphalt section. Subsequently this recycled asphalt will be capped with a thinner final wearing course of ...

Mechanical stabilization uses the pulverized asphalt pavement as an aggregate sub-base, while adding recycled asphalt pavement, crushed virgin aggregate, or crushed concrete for additional strength. This process can be used on its own or alongside chemical and asphalt stabilizing additives.

This stabilized base is then surfaced with asphalt or concrete to complete the process. A comprehensive description of each step of the FDR process, from project analysis to inspection, is provided by the Asphalt Recycling and Reclamation Association (AARA) in its manual (2001). The use of FDR is most appropriate for roads with less than 7 ...

The cement-treated base course is made in a batch mixer by mixing its components (crushed aggregate 0-5 mm and 5-20 mm, 3,5 % type 10 Portland cement by weight, 1,9 % hydrated cement stabilization agent by weight and 1,5% added water by weight). The cement-treated base was precracked transversely at intervals of 2,5 m over 50% to

(6) RCA can be used as an aggregate for cement-treated or lean concrete bases, a concrete aggregate, an aggregate for flowable fill, or an asphalt concrete aggregate. It can also be used as a bulk fill material on land or water, as a shore line protection material (rip rap), a gabion basket fill, or a granular aggregate for base and trench ...

The old asphalt and base materials are pulverized, mixed with cement and water, and compacted to produce a strong, durable base for either an asphalt or concrete surface. Full-depth recycling uses the old asphalt and base material for the new road. There’s no need to haul in aggregate or haul out old material for disposal. Truck traffic is ...

replacement of aggregate base rock materials by use of stabilized soils or stabilized recycled aggregate materials (asphalt millings and crushed concrete). The cost savings for the one mile long city expressway project pictured above was 25% of the overall project cost. While hot mix asphalt was still used as the pavement surfacing,

Samples were prepared using 0, 3, 5, and 7% Type I portland cement and were cured for 3, 7, and 28 days in plastic bags at room temperature. A pavement design analysis of using various cement stabilized RAP-virgin aggregate mixtures as base materials was also undertaken.

Southern Crushed Concrete’s Cement-Treated Base (CTB) is a mixture of crushed concrete combined with carefully measured amounts of cement that harden after compaction to form a durable paving material.
