Gravel /ˈɡrævəl/ is composed of unconsolidated rock fragments that have a general particle size range and include size classes from granule- to boulder-sized fragments. Gravel is sub-categorized by the Udden-Wentworth scale into granular gravel (>2 to 4 mm or 0.079 to 0.16 in) and pebble gravel (>4 to 64 mm or 0.2 to 2.5 in). One cubic yard of gravel typically weighs about 3000 pounds (or a cubic metre is about 1,800 kilograms).

Famous quotes containing the word gravel:
“Let the new faces play what tricks they will
In the old rooms; night can outbalance day,
Our shadows rove the garden gravel still,
The living seem more shadowy than they.”
—William Butler Yeats (18651939)

And another at my feet;
And lay my bent bow at my side,
Which was my music sweet;
And make my grave of gravel and green,
Which is most right and meet.”
