Crushed Limestone vs Rip Rap: Size, Cost, and Which to Use

Crushed Limestone

Crushed limestone is quarried limestone that has been crushed and screened into standard sizes from screenings to 3-inch rock. It costs $20 to $45 per ton in 2026, weighs 1.3 to 1.5 tons per cubic yard, and is the cheapest crushed stone across the Midwest, Texas, Florida, Pennsylvania, and any other region sitting on limestone bedrock. Its light color, low price, and the way its fines cement together under traffic make it the default driveway and road gravel in a big part of the country.

Rip Rap

Large, heavy, angular stones ranging from 6 to 24+ inches used primarily for erosion control. Rip rap protects shorelines, stream banks, bridge abutments, and steep slopes from water erosion. The heavy weight and interlocking shape resist displacement by flowing water and wave action.

Crushed Limestone

• ✓ Driveways
• ✓ Road base
• ✓ Drainage
• ✓ Paver base
• ✓ Concrete aggregate
• ✓ Farm lanes and arenas
• ✓ Landscaping

Rip Rap

• ✓ Shoreline protection
• ✓ Stream bank stabilization
• ✓ Bridge abutments
• ✓ Steep slope stabilization
• ✓ Culvert outlets
• ✓ Retaining wall faces

Crushed Limestone

• + Cheapest crushed stone in the Midwest, Texas, and Florida
• + Fines cement together into a hard surface
• + Light color brightens driveways and beds
• + Every standard size available
• + Packs harder than granite crusher run

• − White dust in dry weather
• − Raises soil pH, bad for acid-loving plants
• − Softer, breaks down faster under heavy trucks
• − Expensive where it has to be trucked far

Rip Rap

• + Extremely effective at preventing water erosion
• + Heavy weight resists displacement by water
• + Long-lasting — lasts decades with no maintenance
• + Angular shape interlocks for stability
• + Natural appearance blends with waterside environments

• − Very heavy — requires heavy equipment to place
• − Expensive for large projects
• − Not suitable for foot traffic
• − Requires engineering design for major installations
• − Limited decorative appeal

Crushed Limestone

Crushed limestone comes in every standard sieve size: screenings under 1/4 inch, #8 (3/8 to 1/2 inch), #57 (3/4 to 1 inch), #4 (1 to 1.5 inch), #2 (2 to 3 inch), and crusher run (3/4 or 1.5 inch minus). It is angular when fresh and wears smoother than granite. Color runs white, cream, light gray, and tan, and it turns bright white as dust dries on the surface.

Rip Rap

Large angular stones typically 6-24 inches in diameter, though some applications use stones up to 36 inches or larger. Weight ranges from 25 to 500+ pounds per stone. Colors vary by source quarry — typically gray, blue-gray, tan, or brown. Sold by the ton rather than by the yard.
