Difference between a Grader and a Road Roller

1.  What is a Road Roller?

   A road roller is a heavy-duty construction machine, also known as a soil  compactor. It’s a type of road construction equipment used for large-scale  road projects such as highways, railways, airport runways, and dams. It can  also be used for compaction work on narrow surfaces such as trench  foundations, building construction, pipeline backfilling, and sports fields.  It is suitable for various cohesive, non-cohesive, asphalt concrete, and  aggregate mixtures.
   
   It’s also suitable for roadbed stabilized soil and other road surface  materials. After the work of a road roller, the road material becomes more  compact, and the road surface becomes smoother. Whether it’s road  construction or other projects requiring leveled roadbeds, road rollers are  indispensable.
   
   Road rollers can be classified in different ways. If classified by working  weight, for the most intuitive representation, the current road machinery  industry often divides them into small road rollers (10 tons and below) and  large road rollers (10 tons and above).
   
2. What is a grader? XCMG

A grader is a versatile modern construction equipment suitable for leveling  ground surfaces in foundation engineering. It can also be used for ditch  digging, slope scraping, bulldozing, loosening soil, snow removal, etc. It is  essential for the construction of high-grade highways, railways, airports,  ports, dams, industrial sites, and farmland leveling.

   (1) Grader: Used to level loose base layers, such as backfill soil,  lime-soil, etc.
   
   (2) Road roller: Used to compact already leveled road surfaces and ground  surfaces, including backfill soil, lime-soil, dry-mixed concrete, asphalt  concrete, etc.
   
   Single-drum road roller: Commonly used with a vibration function to fully  compact backfill soil, lime-soil, etc.
   
   Double-drum road roller: Commonly used static roller to compact and level  road surfaces.
   

4. XCMG Case procedure:

   ① A grader is used to level excavated roadbeds, backfill soil, and  evenly mix lime-soil.
   
   ② After leveling, the roadbed is fully compacted using a vibratory roller  (potholes are repaired and then compacted again).
   
   ③ Once the compacted soil meets design requirements, dry-mixed concrete is  laid, or gravel is sprinkled, and asphalt concrete is spread using a  paver.
   
   The asphalt concrete is then compacted using a static roller, and the road  surface is smoothed using a pneumatic tire roller with water (for cooling).
