PAVING
How we got here...Owner and manager Wayne Houston,
an expert in the field, as well as the son and grandson of pavers,
attended the University of Maryland. In 1988, at 22 years
of age, he decided that he wanted to be the owner of a successful
paving business. Initially called just A.S.A.P, (it was an acronym
for Asphalt Seal coating And Paving); the company has earned
a reputation as one of the very best full-service paving companies
in of the Greater DC Metro area. We got here by keeping our promises. We
know that in keeping our promises, we will keep a satisfied customer!
Our Vision: Together we are building a large,
well-respected and enduring full- service paving company of first
choice serving the Northern and Central Virginia markets.
Our Mission Statement: We will work harder
and more passionately to distinguish ourselves from our competitors
by offering an extraordinary commitment to exceptional customer
service and superior quality. We will deliver to our customers
a better experience and a better product.

Asphalt
(asphalt cement):
|
A dark brown to black cementitious material in which the
predominating constituents are bitumen’s, which occur in
nature or are obtained in petroleum processing. Asphalt is
a constituent in varying proportions of most crude petroleum
and used for paving, roofing, industrial and other special
purposes.

an alligator's skin or chicken-wire, and caused by excessive
deflection of the surface over unstable sub grade or lower
courses of the pavement.
|
|
Asphalt Emulsion
|
An emulsion of asphalt binder and water that contains a
small amount of an emulsifying agent. Emulsified asphalt
droplets may be of either the anionic (negative charge),
cationic (positive charge) or nonionic (neutral).

A course of hot mix asphalt of variable thickness used to
eliminate irregularities in the contour of an existing surface
prior to placing the subsequent course.
|
|
Asphalt Pavements
|
Pavements consisting of a surface course of asphalt concrete
over supporting courses such as asphalt concrete bases crushed
stone, slag, gravel, Portland Cement Concrete (PCC), brick,
or block pavement.
|
|
Asphalt Tack Coat
|
A relatively thin application of asphalt binder applied
to an existing asphalt concrete or PCC surface at a prescribed
rate. Asphalt emulsion diluted with water is the preferred
type. It is used to form a bond between an existing surface
and the overlying course.
|
|
Base Course
|
The layer in the pavement system immediately below the binder
and surface courses. It usually consists of crushed stone,
although it may consist of crushed slag or other stabilized
or unsterilized material.
|
|
Binder Course
|
The hot mix asphalt course immediately below the surface
course, generally consisting of larger aggregates and less
asphalt (by weight) than the surface.
|
|
Coal Tar
|
A dark brown to black cementitious material produced by
the destructive distillation of bituminous coal.
|
|
Coarse Aggregate
|
Aggregate retained on the 2.36 mm (No. 8) sieve.
|
|
Coarse-Graded Aggregate
|
One having a continuous grading in sizes of particles from
coarse through fine with a predominance of coarse sizes
|
|
Compaction
|
The act of compressing a given volume of material into a
smaller volume.
|
|
Crack
|
An approximately vertical random cleavage of the pavement
caused by traffic loading, thermal stresses and/or aging
of the binder.
|
|
Disintegration
|
The breaking up of a pavement into small, loose fragments
caused by traffic or weathering (e.g. raveling).
|
|
Durability
|
The property of an asphalt pavement that represents its
ability to resist disintegration by weathering and traffic.
|
|
Effective Thickness
|
The ratio of the thickness of an existing pavement material
compared to the equivalent thickness of a new HMA layer.
|
|
Fatigue Resistance
|
The ability of asphalt pavement to resist crack initiation
caused by repeated flexing.
|
|
Fine Aggregate
Flexibility
|
Aggregate passing the 2.36 mm (No. 8) sieve.
The ability of an asphalt pavement structure to conform to
settlement of the foundation. Generally, flexibility of
the asphalt paving mixture is enhanced by high asphalt
content.
|
|
Fog Seal
|
A light application of diluted asphalt emulsion. It is used
to renew old asphalt surfaces, seal small cracks and surface
voids, and inhibit raveling.
|
|
Full-Depth Asphalt Pavement
|
The term FULL-DEPTH (registered by the Asphalt Institute
with the U.S. Patent Office) certifies that the pavement
is one in which asphalt mixtures are employed for all courses
above the sub grade or improved sub grade. A Full-Depth asphalt
pavement is placed directly on the prepared sub grade.
|
|
Hot Mix Asphalt (HMA)
|
High quality thoroughly controlled hot mixture of asphalt
binder (cement) and well-graded, high quality aggregate,
which can be compacted into a uniform dense mass.
|
|
Impermeability
|
The resistance an asphalt pavement has to the passage of
air and water into or through the pavement.
|
|
Micro-Surfacing
|
A mixture of polymer modified asphalt emulsion crushed dense
graded aggregate, mineral filler, additives and water. It
provides a thin resurfacing of 10 to 20 mm (3/8 to 3/4 inch)
to the pavement.
|
|
Milling Machine
|
A self-propelled unit having a cutting head equipped with
carbide-tipped tools for the pulverization and removal of
layers of asphalt materials from pavements.
|
|
Pneumatic-Tire Roller
|
A compactor with a number of tires spaced so their tracks
overlap delivering a kneading type of compaction.
|
|
Polymer-Modified Asphalt (PMA) Binder
|
Conventional asphalt cement to which one or more polymer
compounds have been added to improve resistance to deformation
at high pavement temperatures and often cracking resistance
at low temperatures.
|
|
Pumping
|
Slab deflection under passing loads sometimes resulting
in the discharge of water and sub grade soils along joints,
cracks and pavement edges.
|
|
Raveling
|
The progressive separation of aggregate particles in a pavement
from the surface downward or from the edges inward.
|
|
Recycled Asphalt Mix
|
A mixture produced after processing existing asphalt pavement
materials. The recycled mix may be produced by hot or cold
mixing at a plant, or by processing the materials cold and
in-place.
|
|
Reflection Cracks
|
Cracks in asphalt overlays (usually over deteriorated PCC
pavements) that reflect the crack pattern in the pavement
structure below it.
|
|
Seal Coat
|
A thin surface treatment used to improve the surface texture
and protect an asphalt surface. The main types of seal coats
are fog seals, sand seals, slurry seals, micro-surfacing,
cape seals, sandwich seals and chip seals.
|
|
Slurry Seal
|
A mixture of emulsified asphalt, well-graded fine aggregate,
mineral filler or other additives, and water. A slurry seal
will fill minor cracks, restore a uniform surface texture,
and restore friction values.
|
|
Soil/Cement Base
|
A hardened material formed by curing a mechanically mixed
and compacted mixture of pulverized soil, portland cement
and water used as a layer in a pavement system to reinforce
and protect the sub grade or sub base.
|
|
Steel-Wheel Vibratory Rollers
|
A compactor having single or double cylindrical steel rolls
that apply compactive effort with weight and vibration. The
amount of compactive force is adjusted by changing the frequency
and amplitude of vibration.
|
|
Structural Overlay
|
A HMA overlay constructed for the purpose of increasing
the structural value and ride quality of the pavement system.
|
|
Subgrade
|
The soil prepared to support a pavement structure or a pavement
system. It is the foundation of the pavement structure.
|
|
Superpave™
|
Short for "Superior Performing Asphalt Pavement" a
performance-based system for selecting and specifying asphalt
binders and for designing asphalt mixtures.
|
|
Workability
|
The ease with which paving mixtures may be placed and compacted.
