Arman Abu, Natsar Desi, Sri Gusty PERFORMANCE ANALYSIS OF PORUS ASPHALT MIXTURE USING ANTI-PELALING AGENTS WITH REAM SPECIFICATIONS 40 PERFORMANCE ANALYSIS OF PORUS ASPHALT MIXTURE USING ANTI- PELALING AGENTS WITH REAM SPECIFICATIONS Arman Abu 1 , Natsar Desi 2 , Sri Gusty 2 1 Postgraduate Student of Infrastructure and Environmental Engineering, Fajar University, Makassar, INDONESIA 2 Magister of Infrastructure Engineering and Environmental, Fajar University, Makassar, INDONESIA E-mail: armanabu82@gmail.com ABSTRACT Flexible pavement is very weak against waterlogging because water can loosen the bond between aggregate and asphalt. Porous Asphalt has lower durability because it has high pores so that it can be passed by water. Poor bonding of asphalt and aggregate will cause stripping. This peeling can cause water absorption which will eventually accelerate road damage. Derbo 401 anti-peeling material is one of the new breakthroughs, in the form of additives that can change the properties of aggregates and asphalt, increase adhesion and bonding, and reduce the negative effects caused by water so as to produce a mixture of asphalt with high adhesion. The purpose of this study was to determine the effect of adding anti-stripping agent type Derbo-401 to the permeability value and to determine the resistance of the porous asphalt mixture with the addition of anti-striping agent type Derbo-401 in the Cantabro test and to determine the microstructure of the porous asphalt mixture. Using the REAM-2008 Specification. Based on the results of the study, the Permeability Coefficient Value of the porous asphalt mixture was 0.254 cm 3 /sec. the lowest percentage Derbo 0.4%, the lowest Cantabro Loss value at 0.3% addition percentage gets an average value of 6.13%, Has met the required specifications max 15%. The elements that make up the porous asphalt mixture with the addition of Derbo percentage are more in the elements Si (silicon) 19.93%, Ca (calcium) 21.12%, S (sulfur) 8.45%, Fe (ferrum) 8.80%, K (potassium) 2.42% and the other elements are less.

Porous Asphalt has lower durability because it has high pores so that it can be passed by water. Poor bonding of asphalt and aggregate will cause stripping. This peeling can cause water absorption which will eventually accelerate road damage. (Djumari & Djoko Sarwono 2009). Derbo 401 anti-peeling material is one of the new breakthroughs, in the form of additives that can change the properties of aggregates and asphalt, increase adhesion and bonding, and reduce the negative effects caused by water so as to produce a mixture of asphalt with high adhesion. Anti-peeling material is composed of amino polymers that are insoluble in water but only soluble in oil and the concentration is very small when used in asphalt mixtures so that it is not a B3 waste (Toxic and Hazardous Materials) and also does not pollute the surrounding water sources so it is safe for humans. environment. The addition of Derbo 401 as an anti-peeling agent in asphalt mixtures has also been studied by Theresia Marisa Prima Simatupang (2015) Derbo 401 is added to the AC-WC mixture. Good effect on the mixture is indicated by all test results meet the specifications. A similar study was also conducted by Matris Derianza Hafidz et al (2016), using anti-peeling materials. The functional performance of the porous asphalt mixture is also getting better with the permeability coefficient increasing and disintegration getting better along with the increase in anti-stripping wetfix be levels, as evidenced by the decrease in the Cantabro Loss value. Porous asphalt is an asphalt mixture that is being developed for wearing course construction. This layer uses an open graded layer that is spread over a waterproof asphalt layer. The mixture is dominated by coarse aggregate, to obtain pores high enough to obtain high permeability of porous asphalt, where permeability is used for subsurface drain. (Tjaronge, 2013). Porous asphalt has
