How to Stabilize Pea Gravel Walkways (In a Few Easy Steps)
2. Lay Down A Base Layer Of Rock. Pea gravel is round and tends to roll, so laying down a base layer of a more coarse, angular rock can help stabilize the pea gravel. After excavating the area, pour in about three inches of a base layer of crushed rock. The recommended base layer is #3 or #57 crushed stone.

Reflective Cracking in Cement Stabilized Pavements
ture intrusion into the base/subgrade layers is minimal and non-problematic. If the cracking causes no "tenting" or roughness, there may be no need for maintenance action. However, if wide cracks (> 1/4 in. or 6 mm) occur at the pave-ment surface, they can result
CEMENT STABILISED GRAVEL
CEMENTSTABILISERAT GRUS. Owing to the rise in bitumen prices, the use of cement stabilised gravel is becoming an interesting alternative to bitumen stabilised gravel. CG has high flexural strength and therefore wheeltracking is reduced. CG is made at ready mixed concrete plants using well graded aggregate, and standard or other cement.
One of the major issues with cement soil stabilization is that soil-cement shrinks as a result of hydration and moisture loss, which can have deleterious effects where shrinkage cracks will reflect through overlying surfaces or where the loss of a continuous structural slab action or water tightness is desired.

Mix ratio for gravel and cement
· Just reading up on a few Irish and Uk building forums and websites. Most of the builders and blocklayers say to use a mix of 1 cement to 5 batched gravel/ballast for foundations/footings. Alot of them say that 1:4 mix is prone to shrinking and cracking so 1:5 is a good allround mix that is perfect for foundations for walls and garages.

Calculating Cement, Sand, and Gravel
· Match and calculate sand, gravel, and cement quantities using the concrete proportion table: Volume * Cement Multiplier for a Class "C" in 50 kg bags = 12.5m3 * 5 = 62.5 bags. The volume of sand is equal to the quantity of sand. For a Class "C" mix, the sand multiplier is 12.5m3 *.5 = 6.25m3. Gravel Quantity equals Gravel Volume.
