| Improved asphalt mixture that added DAMA for increasing pavement durability
including the control of plastic deformation and reduction of crack and damage
of asphalt. |

Darin Asphalt Modified Additive (DAMA) is a mixed substance of thermoplastic
epoxy (PE) and waste tire rubber dust (CRM) and other substance that asserts
outstanding capability in manufacturing of polymer modified asphalt (PMA)
mixtures. Thermoplastic epoxy (PE) is dissolved in 140 ¡É or higher to merge with
asphalt that it clearly improves the physical properties. Such an asphalt
increases the aggregate cohesiveness as the high precision with high
inflammation point that greatly contribute to the prevention of pavement plastic
deformation at the high temperature in summer. The CRM of micro-some under the
#40 or lower is dissolved on the high temperature asphalt to improve the
physical characteristics of asphalt. And some exists as the grain to take on the
role unique for rubber that it has the effect of lowering the brittle damage in
low temperature. Other materials prevent the aging of asphalt to increase the
durability of pavement. As such, the DAMA asphalt mixture improves the
physical properties of pavement clearly to remarkably improve the relevant
problems on asphalt pavement |

1. Asphalt improving additive of single powder type of polymer modified
asphalt additive (PMA) 2. CRM, thermoplastic and other synthetic substance
|
1. Usable for various asphalt mixtures 2. It increases the inflammation
point (existing 40¡É->60¡É) to slow down the asphalt temperature 3. When
passing the summer high temperature and heavy vehicles, it reduces the plastic
deformation 4. Prevention of winter low temperature brittle
destruction 5. Increasing the aging prevention effect (Effect of adapting to
the temperature change and load change) 6. Stability at 1200kg or more
|
- Added volume: 0.5~1.4% (based on entire mixture weight) - Mixture time:
50 seconds or more - Addition method: After commencing the asphalt spray, the
packed vinyl back is injected into the mixer - Mixed temperature:

- Road with severe deformation like expressway, downtown bypass, industrial
road and others and special pavement like motor racing track and others -
Parking lot, industrial complex, mountain freezing area - Performance: Seoul,
Gyeonggi-do, national highway Yongin motor racing track and many others

1. DAMA asphalt mixture is known to have outstanding effect in preventing
the plastic deformation. 2. DAMA asphalt mixture is likely to make clear
increase of pavement durability. 3. DAMA asphalt mixture is assessed to
clearly increase the cohesiveness. 4. DAMA asphalt mixture is likely to have
a significant effect in preventing the low temperature crack. 5. DAMA can
conveniently be used without additional installation at the existing Ascon
production plant
- Looking at the management test result of site construction and comparison
test of DAMA asphalt, and if the DAMA is added to various asphalt mixtures, it
asserts a great capability to resolve relevant problems for existing asphalt
mixtures in any environment. Therefore, even if it is applied to an area where
the existing surface is somewhat defective, it is likely to make a clear
contribution to the pavement durability increase including the prevention of
plastic deformation and cracks. In particular, when the DAMA asphalt mixture
is produced and constructed by applying DAMA on the super pave size, it surely
seen to be the perfect asphalt pavement of outstanding quality. | |
