Prices should be crushed and run. Crush and run gravel is one of the cheapest materials, costing between $24 and $34 per ton, or approximately $50 per cubic yard, or $0.50 to $2.00 per square foot. This blend consists of limestone, trap rock, granite, crushed rock, sand, and stone dust. It can also include recycled glass, rubber, oil sludge, and wood fibers. The cost of crushed rock depends on the type of material used and its quality. Low-quality material may be cheaper but it will also be less dense and require more volume to achieve the same result as high-quality material. The price per ton of rock drops as quality increases. For example, if we consider two types of gravel: one made of 100% quartzite and the other made of 95% quartzite and 5% limestone. Both have the same size distribution and are graded as medium (not fine or rough). The gravel made of 100% quartzite is more expensive than the other one, but it has greater density so it requires less volume to achieve the same result. In this case, the cost of the former would be about $20 per ton while the latter would only cost $10 per ton. The total cost of crushed rock is determined by the quantity required and the price per ton. If you need 10 yards of medium-grade gravel for your driveway, the total cost will be $100 plus the tax on the merchandise ($15 in Massachusetts).
