Durable road surface - Continuous compaction guards against the road-damaging effects of water by decreasing permeability and maintaining proper drainage. A compacted road is less likely to succumb to sub-grade saturation problems that ultimately cause road failure.
Safety - Soft shoulders, ruts, loose gravel and uneven surfaces pose a serious hazard to drivers. Because continuous compaction creates a more stable, erosion resistant surface, it significantly reduces or eliminates these and many other potential hazards.
Routine maintenance normally misses a critical practice SURFACE COMPACTION
Surface compaction - surface compaction is the process of tightly packing the surface soil particles by removing air pockets. By applying pressure to the surface through rolling or tamping loose material, compaction presses the air out of the soil creating a packed and stable surface. Continuous compaction is the road management practice of using a grader-mounted compactor to compact the road surface after every maintenance procedure.
