Most large U.S. projects have been placed with a high-production pugmill and high-density paver. The latter is especially critical for both thick lift pavements (more than 8 inches) or if the surface is going to be left exposed.

For city streets and other projects that may be capped with hot mix asphalt (HMA), more conventional pavement and mixing equipment is often utilized.

Step 3: Select test strip location

The test strip can be incorporated into the project. The area should be large enough so that all facets of the job, including fresh joints, can be installed.

Most test strips are a minimum of four loads.

Step 4: Manufacture the mix

The production facility that will be used for the project should manufacture the RCC for the test strip.

If the material supplier and installation contractor are different companies, require the supplier to mold cylinder specimens according to ASTM C1435 to document that the mixture was properly batched.

Batch within tolerance but slightly above the optimal moisture content to account for any moisture loss during transportation.

Don’t install the test strip with RCC made from a local ready-mix plant when a pugmill will be used for the project.
