The gravel (coarse aggregate) on highways plays a skeleton role in concrete, called aggregate or aggregate, where the aggregate with a particle size greater than 4.75 mm is called coarse aggregate. The commonly used coarse aggregates for ordinary concrete include crushed stones and pebbles. Crushed stone is a rock particle with a particle size greater than 4.75 mm made by mechanical crushing and screening of natural rocks, pebbles, or mine waste rocks. Pebbles are rock particles with a particle size greater than 4.75 mm that are naturally weathered, transported and sorted by water flow, and accumulated.

With the higher requirements for sand and gravel in highway construction, equipment such as sand making machines, sanding machines, and sand making machines for producing stones and sand have also put forward more horizontal requirements.
