Granite promotes the use of reclaimed asphalt pavement (RAP) and warm-mix asphalt (WMA), two products that conserve raw materials and energy, cut emissions from operations and improve conditions for workers. Using RAP is usually more cost-efficient, and it's often equal or greater in quality than traditional methods.

Geology Joshua Tree Nature Trail Arch Rock The Formation of Granite This type of rock is called White Tank Granite. It is an igneous rock which formed when hot magma or liquid rock was pushed up from deep within the Earth and forced into the overlying rock in a process known as intrusion.

ANSWER Granite is formed by the solidification of magma under the earth's surface. More Info To form granite, magma must first cool underground. This is an extremely slow process. Since the time required to form granite is rather long, it is both a strong and valuable stone. Granite is actually made up of several different minerals including feldspar and quartz.
