- Nidagravel 140.
- Tarmac planings.
Does crushed asphalt make a good driveway?
When it’s compacted, the material is able to harden and bind together. This makes it a great pick for use on driveways because it serves as a strong and cost-efficient base or sub-base material. For best results, the material should be professionally spread after properly grading and excavating the driveway.
