Compaction Testing: Compaction tests ensure that the asphalt is properly compacted to achieve the required density and strength. The narrow frames offer great sight lines so you can get the best view of your Asphalt pavement compaction quality control and quality assurance (QC/QA) are traditionally based on destructive drilled cores and/or nuclear gauge results, which both are spot measurements representing significantly less than 1 percent of the in-service pavement. Especially for compaction, the variables of how much HMA is produced and when it’s delivered influence the temperature of the asphalt when compacted. Using asphalt patch on concrete is usually temporary. It consists of a heavy steel plate mounted on a vibrating base, which generates downward force and vibrations that help to compact the material beneath it. Application guide. Depending on the repair's size, an asphalt roller, a plate compactor or a tamper tool can be used to compact the millings, ensuring a smooth, solid finish. ” Engle said compaction does vary when you need to compact base materials that were replaced or added during the cut-and-fill method.
