the road, chemical stabilisation of the local materials often provides a cheaper option than hauling higher quality materials over long distances, or using expensive crushed stone. Improving locally available gravels on roads where traffic levels are relatively low can be a particularly cost-effective alternative.

Gravel roads are considered superior to earth roads. Camber is provided 1 in 25 and 1 in 30. Gravel roads may be constructed in form of trench type or feather edges type patterns. The depth of the trench is dependent upon the thickness of the gravel pavement to be …

Crossfall (or cross slope) The slope, at right-angles to the alignment, of any part of the carriageway. Superelevation is the continuous transverse slope normally given to a carriageway at horizontal curves. Basically, the terms all refer to the same thing. In fact one reference (ref. 1037) refers to superelevation, cant and crossfall in the ...

the gravel drainage layer. This was accepted. Saving in excavation was 600 x 30 x 0.19 m = 3 420 m3 (for off-site disposal). Saving of imported gravel was 600 x 29 x 0.2 = 3 480 m3. Apart from the costs, this also saved over 600 round-trip lorry movements. Drainage layer beneath underpass prop slab

1 Characteristic of geotextiles in highway engineering 1.1 Physical properties. 1) Heat resistance.The melting point of geotextile fabric at room temperature is high, which can reach 260 ℃, while the temperature of asphalt material laid on-site in the process of highway construction is 150 ℃, which is much lower than the melting point of geotextile.

Wood's definition :- Aggregate is an aggregation of sand,gravel,stone,slag or any other material,in combination with some cementing material attains higher engineering properties and form highway materials like WBM,BM etc. Road aggregate, or simply "aggregate", is a broad category of coarse particulate material used in construction ...
