DESIGN AND PROPERTIES OF SPLIT MASTIC ASPHALT MODIFIED WITH RETONA AT HOT AND ARID REGION
Abstract: The use of Retona as
the additive material in the hot mix
split mastic asphalt with a certain comparison is expected to improve the
quality of the split mastic asphalt. This study aimed to determine the extent
of Marshall properties (Stability, Flow, Marshall Quotient, VITM, VFWA, and Air
Void), ITS and UCS test at (30ºC, 40ºC, 60ºC) and Permeability Test. The
objective of that is a comparing the results between SMA (AC 60/70) and SMA
modified with retona to know the properties if to be used at hot and arid region. In comparison with the results
of Marshall Test SMA modified with Retona and SMA (AC60/70) are : the stability
value is higher by 11.52%, the flow value is lower by 11.89%, the marshall
qoutient value is higher by 26.65%, the VITM value is lower by 1.93%, the VFWA
value is higher by 90.57%, and the Air
Void value is lower by 9.34%. The ITS value of SMA without Retona is higher
than SMA with Retona is 49.28 % at
temperature 40oC. The UCS value of SMA without Retona is higher than SMA with Retona
is 18.99 % at temperature 30oC. The SMA modified with Retona is less sensitive
to temperature changes by using ITS and UCS test compared with SMA without
Retona. The coefficient of permeability value of SMA with Retona is higher than
SMA without Retona 294% at water
pressure 10000 dyne/cm² and by 348 % at water pressure 20000 dyne/cm². Where
find that the mixtures are Practically impervious.
