PENGARUH PERENDAMAN ASPAL PORUS YANG MENGGUNAKAN LIQUID ASBUTON TERHADAP STABILITAS MARSHALL DAN KETAHANAN SEGRESI PADA AIR LAUT DENGAN SUHU BERVARIASI

Mixture of porous asphalt have several advantages for users of the road and around the way, which is: the drainage function, the function of the safety of drivers, and road noise reduction function. This is due to the voids (porosity) are contained in porous asphalt mixturesis substantial. Large cavity can cause a decline in the value of the characteristics on porous asphalt mixtures. Load bearing capability (stability) in a mixture of porous asphalt is drastically reduced when compared to conventional asphalt mix (dense graded asphalt). Asphalt has a molecular structure is highly complex and varied in size and different of chemical bond. All of these types of molecules interact with each other in a different way, interaction among these molecules effect not only the chemical properties of the asphalt but also the physical properties of asphalt. Basically the high temperature induce the formation of Co and O in sea water. If the mixture at high temperature suddenly cooled, Co, in this research contains minerals of sea water will react with other compounds in the asphalt and the reaction accelerated with increasing temperature The Asbuton liquid is new innovation from Asbuton rock manufacturing that consist of CaCO3. MgCO3,CaSO4, CaS, SiO2, Al2O3+Fe2O3 And H2O, that could give reaction from others chemical compounds. At elevated temperatures the most common problem is the deformation, whereas at low temperatures problem that often occurs is cracked and the loss of fine particles from the surface of the pavement.. To testing the working of porous asphalt, we have done research in laboratory by making sample using open graded trial gradation material as many as 60 sample with variety of temperatures of seawater (25??C and 60??C) and also variety of immersion duration. From the research result is knew the characteristic of the porous asphalt with cantabro value ranging from 8.86% to 50.18%, and marshall stability ranging from 264.33 kg kg to 847.61 kg which test by variety of seawater temperature
