Aggregates | Mines quarries | MineralsUK
Aggregates account for approximately 85 per cent of the non–energy minerals extracted in the UK and, are critical for the national economy. The construction sector relies on the supply of construction aggregates, obtained from 1300 quarries in Britain, dredged from the sea bed by a fleet of 28 marine aggregate dredgers and through recycling.

The Complete Guide to Crushed Stone and Gravel
· Because large stones and quarries are hard on tires and require heavy metal, crushed stone was hard to make and transport until heavy machinery with tracks was developed. WW2 expedited the development of this machinery, and crushed stone began to be widely used in construction projects in the 1940s and 1950s.
Estimating carbon dioxide emissions for aggregate use ...
Tools such as the carbon dioxide estimator tool from the UK Waste and Resources Action Programme (WRAP) and Aggregain have been developed to allow engineers to quantify and optimise carbon dioxide emissions associated with aggregate use. An extended WRAP tool methodology has been developed and is illustrated through assessing the relative carbon dioxide performance of different aggregate ...

Section III: Surface Gravel
gravel will often be blamed on the maintenance operator. But the operator cannot make good gravel out of bad gravel. Bad or poorly graded gravel can not be changed to good gravel without additional costs, but it is often well worth it. One common practice of improving surface gravel is to add new, clean, fine gravel. Good surface gravel
