The hardness and toughness of the binder surface more than of the rock itself represents the hardness and toughness of the road, for if the weight of traffic is sufficient to destroy the bond of Cementation of the surface, the stones below are soon loosened and forced out of place.

Time, as I have explained in Chapters 5, 6, and 7, has multiplied the effects of condensation by pressure and Cementation, and the modification produced by heat, fracture, contortion, upheaval, and denudation.
"The Student's Elements of Geology"
Sir Charles Lyell
Igneous rocks as a rule are compact, and hence are not so much subject to the processes of Cementation as sedimentary rocks; but certain of the more porous phases of the surface lavas, as well as any joints in igneous rocks, may become cemented.
