Rebar is a steel bar that is used in concrete construction. By adding these reinforcing steel bars, you’re creating reinforced concrete. Whether your project includes floor slabs, walls or posts, rebar helps keep cracks that form from making the project fall apart. Though all concrete cracks, rebar, and reinforcing materials help control where and the extent of the cracks. It also provides structural strength to the project.

Asphalt paving cements
The binders for the more expensive asphalt
pavements are usually asphalt cements
These semis olid materials are also separated
into grades having different ranges of
hardness
Asphalt canal liner and bank erosion control
The versatility of asphalt has led to its
employment in many types of hydraulic
structures
Mixes made with the harder asphalts
The term bitumen is a generic name applied to various mixtures
of hydrocarbons
They may be gaseous, liquid, semisolid, or solid
Most common materials within the family of bitumen’s are
tars, pitches, and asphalts
Destructive distillation is carried out on natural materials
produces tar
Partial evaporation or fractional distillation of tar produces
the solid or semi-solid residue of pitch
Asphalts are dark brown or black solids or semi solids which
are found in the natural state and are also produced by the
refining of petroleum
Some natural deposits of asphalts are found in Kentucky,
Utah, Colorado, and California
95% of asphalt materials used in North America are derived
Trom the refining oT petroleum
Asphalts are the most common and most widely used bituminous
materials
The term “asphalt” refers to a black cementitious material which
varies widely in consistency from solid to semisolid at normal
temperatures
Asphalts are found as natural deposits or are produced from
petroleum crude
The classification of asphalts is already presented in the previous
slide
Natural Rock asphalts are rock deposits containing bituminous
materials which have been used for road surfaces in localities
where they occur
Native asphalts are obtained from asphalt lakes in Trinidad and
other Caribbean areas, these were used in some of the earliest
pavements in North America
Petroleum asphalts are products of the distillation of crude oil
These asphalts are used as the most common bituminous paving
materials
