The material is increasingly being used at domestic properties as a low cost and environmentally friendly alternative to concrete and block paving in paths and driveways. [1] A compacted sub-base of larger crushed stone is often laid prior to the top layer of hoggin, especially if the area to be covered is soft ground, or prone to puddling. The ...
Ground reinforcement is a reinforcing element placed on a flat surface in order to increase accessibility for vehicles and ensure proper rainwater drainage in addition to protection. The reinforcing element, usually in the form of grids, is used beneath grass , asphalt , concrete in roads , parking lots , driveways and paths .
Concrete work is efficient and controlled as CCS functions as ready-made forms; CCS with concrete forms a flexible slab that accommodates minor subgrade movement and prevents cracking. In medium and low flow-velocities, CCS with geomembranes and gravel cover can be used to create impermeable channels, thereby eliminating the need for concrete.
Rubblizing of pavement: Existing concrete pavement is milled into gravel-sized particles. Any steel reinforcing is removed, and the ground pavement is compacted to form the base and/or sub-base layers for new asphalt pavement. [35] Ground pavement may also be compacted for use on gravel roads. [34]

Barrett began working using geotextiles behind precast concrete seawalls, under precast concrete erosion control blocks, beneath large stone riprap, and in other erosion control situations. [2]
In Europe, sizing ranges are specified as d/D, where the d shows the smallest and D shows the largest square mesh grating that the particles can pass. Application-specific preferred sizings are covered in European Standard EN 13043 for road construction, EN 13383 for larger armour stone, EN 12620 for concrete aggregate, EN 13242 for base layers of road construction, and EN 13450 for railway ...
