This document discusses reclaimed asphalt pavement (RAP) - material removed during road resurfacing that contains bitumen and aggregate. It notes that RAP was often considered waste, but can be reused. It proposes increasing RAP reuse by developing management systems to track quantities and quality, and control how much is reintroduced into new asphalt. The document also notes that some old asphalt may contain carcinogenic tar, so those materials require separate treatment.

1. WASTE MANAGEMENT BUSINESS

2. What it is RAP ?
 RAP it is a mix of Bitumen and stones , sand , filler taken away from
the road.
 We do have a lot of milling operation when we want to replace an
asphalt layer.
 This material represent an old asphalt which lost from the qualities
where in the beginning.
 Usually this material is transported in stockpiles in diferent places.
 This product it was treated like a “waste” in the industry in many
countries didn’t pay attention to it.
 In some countries it is re-used in different ways( sub-base , or in small
percentages in hot asphalt , and it is re-used in low traffic roads as an
temporary solution)

3. IS it Dangerous ?
Most of the RAP is not dangerous for the health or
environment.
But due to the history we may learn that some of the old
asphalt layers may have tar in composition. This tar was
classified as carcinogenic product.
For this type of material we need to isolate this type of
material and to treat it specifically.

4. Who owns RAP ?
The actual RAP it is coming from old asphalt
When it was manufactured and laid , this asphalt was paid by
the client (most of the time it is State , County Counsels or
Town Ship administration)
The Roads (99%) belongs to public and are paid from public
budgets
When we replace the asphalt what is happening with the
property title of RAP?
Is there any organized national control in order to check out
if this product is not going back in the new asphalt without
the client to know and consent?
When no control policy in place RAP accumulates in huge
stockpiles of waste ( UK , Germany , Hungary ) which start
to produce cost !

5. Our proposal to you
 Re-using of RAP to be as much as possible.
 To find the best way to increase this quantities according with the
Contractor existing equipment and very low investment.
 To implement Country Wide RAP management so to be well known
how much is re-introduced in sistem , and how much there is available
on the market.
 To implement a system to control the quality of RAP , if it is re-usable ,
or it should be classified as dangerous
 We do have the know-how to help in rising the percentage of RAP reused in a time when the economical issues are more and more
highlighted.
 WE do have the know-how to make the recycling in an environmental
way which which does not affect the quality of new asphalt although this
is regenerated with high economy .

6. Value of RAP
 The value of RAP in some countries like Czech Republic or Canada has
a clear way where it becomes valuable. The contractors are transporting
this waste in special places where becomes an inferior product to be
used as a filling material.
 This days a lot of equipments where developed to crush and select the
different size material for re-use after.
 In fact the best value of RAP is to be RE-USED in WARM Asphalt as
much as possible .
 The limitations are in technologies developed till today and the
Chemistry side.
 When we say that we are using RAP 10% it means we are recover 10to
of asphalt for each 90to of new.

7. IMPLICATION OF
GOVERNMENT
Supervise and regulate using and disposing of RAP
throughout the territory
Storing the RAP – the new reclaimed asphalt will be milled
according to the asphalt granulometry.
Historic stockpiles of RAP – according to the content of
environmentally risk factors, their destination will be
determined (hot reclaimed asphalt mix or ecologically burnt).

8. HOW DOES IT WORK?
Company’s mobile
c
hot mix plant
Moves from one deposit to
another to produce Hot Asphalt
OR
Company subcontractscanother hot
mix plant operator
c
EU GRANT
Should prepare his production
facility & equipment according
to technical designs the
licensed company demands of
him. Additive will be delivered
to them.
Company can acquire a brand new
container and a fully equipped
laboratory
