Before lay down a gravel driveway , it is crucial to create a solid foundation garment by laying down several bed . These stratum will not only provide support but also promote right drainage , which is of the essence for preventing wearing and maintaining the longevity of the driveway . for set the amount of material needed for each stratum , we must first calculate the volume in cubic yards .
1 . Base Layer : The base level serves as the basis for the driveway and consists of large low stones . These Stone supply stability and support to the upper layers . To determine the amount of large crushed gemstone needed , quantify the length , width , and desire thickness of the base layer .
For example , let ’s say the private road dimensions are 10 animal foot by 20 feet , and we want a al-Qaeda layer thickness of 6 inch ( 0.5 foot ) .
Volume = Length x Width x ThicknessVolume = 10 ft x 20 ft x 0.5 ft = 100 cubic human foot
Since there are 27 cubic feet in a cubic yard , we need to convert the volume to three-dimensional thou :
book ( three-dimensional yards ) = 100 cubic feet / 27 = about 3.7 three-dimensional yards
Therefore , we would require approximately 3.7 cubic yards of large crushed I. F. Stone for the radix layer .
2 . Sub - base Layer : The sub - base layer is the next layer , consisting of small crushed Isidor Feinstein Stone . This stratum helps to further stabilize the drive and provide a smooth surface . The heaviness of the sub - base layer will reckon on the overall thickness of the drive and the specific requirements of your undertaking .
Let ’s take we want a sub - base stratum heaviness of 4 inches ( 0.33 feet ) for our driveway .
Using the same proportion as before , we can calculate the loudness of the sub - base stratum :
Volume = Length x Width x ThicknessVolume = 10 ft x 20 ft x 0.33 ft = 66 cubic feet
Converting to three-dimensional yards :
loudness ( cubic yards ) = 66 cubic feet / 27 = some 2.4 cubic M
Therefore , we would need approximately 2.4 cubic pace of belittled humbled gemstone for the sub - baseborn layer .
3 . Top Layer : The top layer of the gravel driveway is the final decorative layer that bring home the bacon a ruined looking at . This level consist of crushed rock , which comes in unlike size and colors . The amount of gravel needed will depend on the desire heaviness and the airfoil region of the driveway .
Let ’s assume we require a top layer thickness of 2 inches ( 0.17 metrical foot ) .
Using the same dimensions as before , we can calculate the mass of the top layer :
loudness = Length x Width x ThicknessVolume = 10 foot x 20 ft x 0.17 ft = 34 cubic feet
Volume ( cubic yards ) = 34 cubic metrical unit / 27 = approximately 1.3 cubic yards
Therefore , we would postulate approximately 1.3 cubic yards of crushed rock for the top level .
To summarize , for a typical crushed rock driveway with dimensions of 10 foot by 20 foot and desired layer thickness of 6 in for the base layer , 4 inches for the sub - mean stratum , and 2 inch for the top level , you would necessitate around : – 3.7 cubic M of large humiliated stone for the nucleotide stratum – 2.4 three-dimensional yard of smaller broken Stone for the sub - base level – 1.3 three-dimensional yards of crushed rock for the top layer .
It ’s important to note that these calculations are estimates , and it ’s always a good idea to purchase slightly more material than calculated to report for any variations in thickness or compaction . Additionally , consulting with a local supplier or contractor can furnish more precise selective information base on the specific conditions of your private road project .
