Various oil shales and asphaltic deposits are essentially original sediments which have subsequently undergone more or less decay and distillation.
Large amounts ofasphaltic and bituminous rock, used mainly in paving, are normally produced in Alsace, France, and in Italy.
In some cases the asphaltic material is found as impregnations of sediments, and appears to have remained in place while the lighter organic materials were volatilized and migrated upward.
Oil and gas are distillates from these oil shales and asphaltic deposits, and also from other organic sediments such as carbonaceous limestones.
Excellent foundations for steam-hammers, dynamos and high-speed engines are made of asphaltic concrete.
The asphaltic cement is then added, and the materials are mixed to a homogeneous mass, which is ready to be taken to the street.
The asphaltic cement and sand are heated separately to about 300 deg.

Of the Chapote, an asphaltic ebullition on the surface of the sea, I shall speak more fully in another place, in connection with a similar phenomenon observed in the lakes of Mexico.
Now, if the asphaltic ebullition finds its way up through the lakes, would it not, certainly, and from necessity, carry the water along with it?
There can be no doubt that the ebullition and effluvia observed in the Gulf, are the effect of the same cause, which produces the asphaltic substance on the surface of the Lakes.
Behind that asphalticbosom the murmur of the brook is like an insidious underground stream, and when for a moment it gushes to the surface men pay the five hundred dollars down and inclose return postage for the flower-seed catalogue.
Behind that asphaltic bosom and behind faces too tired to smile, hearts bud and leafen when millinery and open street-cars announce the spring.

Throughout the neighbourhood the ground is full, to the depth of hundreds of feet, of coaly and asphaltic matter.
The mud volcanoes of Turbaco, in New Granada, famous from Humboldt's description of them, lie in an asphaltic country.
But in the year 1850, a 'bituminous odour' had begun to be diffused; asphaltic oil swam on the surface of the small openings; and the gas issuing from any of the cones could be ignited.
Thus the curious have but little information about anything concerning the Asphaltic Lake.
The Scripture itself informs us that all this land was asphaltic before the burning of Sodom: "And the vale of Sodom was full of slime-pits; and the kings of Sodom and Gomorrah fled and fell there.
These are provided with returns, and with the asphaltic wearing surface on the floors of such bridges prevent moisture coming in contact with the structural timbers of the bridge.
An asphaltic wearing surface prevents moisture coming in contact with the wooden floor and with the treated piling tends to give the maximum length of life to the main members of the structure.
Like the others constructed by the State on main highways, this bridge is of heavy traffic design, and the bridge and approaches have laminated wood floors with asphaltic wearing surfaces.
An asphaltic wearing surface three and one-half inches thick effectively waterproofs the wood, and the small interstices between the pieces will allow sufficient circulation of air to preclude any possibility of attack of dry rot.
The crossing was designed to carry 20-ton trucks and the covered spans have laminated wood floors with asphaltic wearing surface.
A laminated wood floor system is used and provision is made for an asphaltic wearing surface although a three inch wooden decking is used temporarily.
I have collected asphaltic coals, very similar to Grahamite and Albertite in appearance and chemical composition, in Colorado and Utah, where they occur with the game associates as at Tampico.
In Canada, the black asphaltic oil forms by its evaporation great sheets of hard or tarry asphalt, called gum beds, around the oil-springs.
Similar anthracitic asphalt or asphalticanthracite is common in the Calciferous sand-rock in Herkimer County, New York, where it is associated with, and often contained in, the beautiful crystals of quartz for which the locality is famous.
So, when a quantity of water bursts its way through the asphaltic soil, it carries asphalt out with it, and after passing out of the ground, the water is separated and so rejects the asphalt from itself.
Asphaltic materials and tars are widely used as fillers for brick pavements.
Sometimes asphaltic concrete is used for resurfacing water-bound macadam or gravel roads when the traffic has increased to the point where the cost of maintenance of the water-bound macadam has become excessive.
Asphaltic concrete is of two general types known as bitulithic, or Warrenite, and Topeka asphaltic concrete, respectively, the differences being in the nature of the mixture.
This type is designated as asphaltic concrete because of the analogy of the mixture to Portland cement concrete.
The asphaltic concrete surface is of excellent riding properties, is easily repaired and of moderate durability.
Asphaltic Concrete Asphaltic concrete is a name given to a road surface mixture which is composed of graded stone, graded sand and asphalt cement.
Usually if the traffic is of a character requiring a concrete foundation, it is desirable to use a better wearing course than the mixed macadam, and the asphaltic concrete or sheet asphalt type of surface is employed.
Asphalt cements are used for sheet asphalt and asphaltic concrete construction and for hot-mixed bituminous macadam.
The solid asphalticmaterials used for hot-mixed types of construction are called asphalt cements.
The foundation for the asphaltic concrete may be an old macadam road, a base course constructed of broken stone or Portland cement concrete, the latter being used much more extensively than either of the other types.
Their efficacy depends upon the binding properties of the small amount of asphaltic material that is contained in the oil.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "asphaltic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
