In the world and in our country, research
has been carried out in order to improve
the behavior and durability of the asphaltic
folder of the different roads designed for
the intercommunication of the towns.
From the asphaltic one, it is necessary to
have the same effect as the one of the
asphalt mixture, which is positively and
sustainably derived from its technical and
scientific applicability. Folder and
especially to its period of durability.
For the analysis of the behavior of the
mixtures, the study was based on the
design of a hot asphalt mixture (standard)
by the Marshall method, which served as
reference for the comparison of its
physical - mechanical properties with
respect to asphalt mixtures added with
Certain percentages by weight and / or
volume of slag. Concluding in two tentative scenarios
when comparing them with sample "A"
(standard sample), for the design of the
asphalt mixture with steel slag, as sample
"B" and "E".
According to the results obtained and its
relation to Stability - Fluency, adequate
able to maintain its shape under repeated
loads, making this a flexible pavement
suitable for Ecuadorian highways. Sample
"B" was determined for its design.
This sample complies with the design
parameters established with proportions of
37.80% of coarse aggregate (slag),
48.87% of intermediate - fine aggregate,
5.53% of Filler and 7.8% of AC - 20
asphalt cement.
Allowing this way to give an alternative
solution in its reuse and its problematic
concerning its location and final deposit of
steel slag. |
