This report presents a technical evaluation of selected saw technologies, tools, and methodologies for improving the efficiency of sawing around damaged pavement associated with crater repair. Previous evaluations of saw technologies identified the Caterpillar SW345B and SW360B wheel saw attachments as the best tools for cutting portland cement concrete for Rapid Airfield Damage Recovery (RADR). However, the next generation of RADR is focusing on lighter and leaner efforts, particularly in regards to equipment size. Selected saw technologies slightly larger and heavier were included in the evaluation in hopes that the saw-cutting rates increased significantly from those of the Caterpillar SW345B and SW360B wheel saw attachments. The evaluation results of all selected saw technologies were compared to the performance of the Caterpillar SW345B and SW360B wheel saws. Results indicate the wheel saw attachments tested are not lighter, leaner, or faster than the SW345B and SW360B wheel saw attachments. The results also showed that a diamond-blade saw attachment, when compared to a walk-behind diamond-blade saw currently utilized for ADR, is more ideal for concrete crater repairs.
