NDS Gravel Pavers - Design The proper design and installation of EZ Roll TM Gravel Pavers results in a self-draining system that saves money on additional drainage and retention systems. Design Considerations: • High-traffic areas should have a slope less than 8% • Light-traffic, bicycle and pedestrian areas can have a slope of up to 10% • Percolation rates of underlying soils should be between 0.64 cm of water per hour • Water table should be approximately 3 feet below base course • Bedrock should not be closer than 2 feet below base course • Surrounding hardscape areas should be slightly higher than gravel paver surface • Gravel paver installation should be at least 10 feet away from building structure • Keep adjacent areas free of sediment and erosion Depth of Base Course To calculate the depth and composition of material for the base course, consider: • Load-bearing capacity of subsoil • Plasticity or impact of moisture • Frost-heave potential • Traffic load Typical base course depths are: • Golf carts and pedestrian traffic – 0 to 4 inches • Cars and light vehicles – 0 to 6 inches • Buses, trucks and fire engines – 6 to 12 inches Always consult with a soil engineer for site-specific base requirements. Compact base course with a vibrating plate type compactor or a heavy motorized roller. Test porosity of base course with a water hose to see if water drains properly through base course. 10

It is a perfect add-on to a custom home -Nunc looking ipsum to ligula be different.” Typical Base Course Materials A mixture of stone and sand or a sandy gravel material allows for a free-draining structural base for use in light to heavy load applications. A clean stone base contains most void space for storage of stormwater and minimizes or eliminates runoff. A clean stone base may be used for light to moderate load applications only. Recommended fill material: Use up to 3/8" angular stone or up to 1/2" round stone. Round stone is more susceptible to movement and migration. Other materials may be used. Permeable Base AASHTO #57 permeable subbase material defined as: Sieve Size Percent Passing mm 37.5 25 19 12.5 9.5 4.75 2.36 in. 1-1/2 1 3/4 1/2 3/8 #4 #8 #57 100 95-100 25-60 0-10 0-5 Typical 100 97 75 45 25 5 2 Other permeable Gradations include AASHTO #5, 6, 7, or sandy gravel material. Crushed Stone A “Crusher Run” base material. 20-40% sand may be mixed with the base material to ensure a porous base. Alternative products may be used based on availability, such as sandy gravel. Ensure that the surface of the base course is smooth and compacted. Avoid the use of 100% crushed limestone. Lime absorbs moisture and is capable of solidifying. Other materials may be used. 11
