The exact make-up of a road will depend on several variable factors such as the weight and volume of traffic it has been designed to carry, local climatic conditions and the availability of mineral aggregates. In most cases, bitumen will be needed for its properties of waterproofing and durability and as the cheapest adhesive generally available. A minor secondary road may use bitumen only for its top two courses, at the rate of 7 tonnes per kilometre. A highway engineer may call for three asphalt courses, with tack coats in between, because of asphalt's superior load bearing properties. In this case, bitumen consumption can amount to 1,000 tonnes per kilometre. The bitumen percentage in asphalt is usually between 4-8%.
About 1.2 tonnes
Densities vary slightly, but with normal hardstone (high Polished Stone Value) aggregate 2.38 to 2.40 tonnes per cubic metre is the number you're looking for. This assumes voids content of between 4 - 8%, in other words, laid to Specification. Hope this helps:-) Bill Galer Reinstatement Contracts Manager, Wessex Water
Around 350 million tonnes.
A normal mountain weights around 100 billion tonnes however LARGE LARGE mountains like mount everest weight aroung 16 trillion tonnes.

0.225 Tonnes
A depth is required to answer your question. The mass of the water will be one million tonnes per metre of depth.
(1.) Russia 3,564 tonnes 1. The Ukraine (840 tonnes) 2. Czech Republic (258 tonnes) 3. Romania (75 tonnes) 4. France (8 tonnes)
225 kilograms = 0.225 tonnes
2190 kilograms = 2.19 tonnes
777 kilograms = 0.777 tonnes
