Advantages of Spike Enhanced Compaction
A. Increased penetration
1. How spikes enable penetration into the compacted material
Penetration depends on the amount of pressure exerted at a point. Spikes reduce the area in contact with the material. Since the drum’s weight is constant, this increases the pressure at the tip of the spike leading to penetration.
2. Comparison with traditional smooth-drum compactors
The drum weight to compaction area of smooth drum rollers is lower than that of spiked rollers. As a result, less pressure is applied on the material at an instance. Smooth-drum rollers need more passes to attain deep compaction compared to those with spikes.
B. Enhanced soil aggregation
1. How spikes disrupt the soil particles, promoting better compaction
Spike-equipped drums on a roller compactor penetrate soil, breaking clumps and creating voids. This action redistributes particles, enhancing soil density and uniformity, resulting in improved compaction by reducing air pockets and increasing material interlocking for greater stability.
