Their colour varies from dark gray to black. Fractures and joints are common. Their weight varies from 18 kN/m3 to 29 kN/m3. The compressive strength varies from 200 to 350 ...
Basalt is a volcanic stone, used in architecture for centuries. Although basalts boast the durability of a granite, they have the consistent coloration, markings and subtlety of a limestone. Basalt is neutral in color and doesn't etch when exposed to acidic foods, making it popular kitchen countertop material.

More over, during this service life concrete road do not require frequent repair or patching work like asphalt roads. Vehicles consume less fuel: A vehicle, when run over a concrete road, consumes 15-20% less fuel than that on asphalt roads. This is because of the fact that a concrete road does not get deflected under the wheels of loaded trucks.
The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It wants to be there, and heat is the key which unlocks the door. As it turns out, most of the ocean floor is basalt, and most of the continents are granite. Basaltic crust is dark and thin and heavy, while granite is light and accumulates ...

Basalt, dolerite (and some other igneous rocks), and greywacke fulfil all six criteria and so are the best rocks to use for the wearing course, but their outcrops are not evenly distributed so transport costs are high. Rocks that are very poor are shale and oolitic limestone. Flint is very strong but would not be a good rock to use.
