The Stability

Abstract Inundation due to heavy rain often disturbs traffic flow and porous pavement as a wearing course is one solution to overcome standing water. This asphalt mixture uses an open gradation which is dominated by coarse aggregate with an air cavity content ranging from 20% - 25%. In Indonesia, according to the Indonesian Solid Waste Association (2013), this type of plastic waste ranks second with 5.4 million tons per year and is ranked second in the world as a producer of marine plastic waste after China. This research tries to use plastic waste as an added material in the porous asphalt mixture where the gradation of porous asphalt refers to REAM Specifications, 2008. The type of plastic used is Low Density Polyethilene (LDPE). The levels of plastic waste used were 0%, 2%, 4%, 6%, 8% of the total weight of the mixture. Marshall and Cantabro characteristics tests were conducted to evaluate the resulting mixture. The results of this study indicate that the stability value meets the REAM specifications, namely 350 - 800 kg. Marshall test results with the use of LDPE plastic waste as an additive to the test object meet the characteristics of Marshall except for Marshall Quotient (MQ) and voids filled with bitumen (VFB).

The Relationship

Based on the Bailey method for aggregate grading design and evaluation, the parameter "reserved voidage" is used in porous asphalt method design. The paper studies the relationship between the three parameters (reserved voidage, blend by volume of the coarse aggregates totaling 100.0% and chosen unit weight of coarse aggregate) and the pavement performances, such as deformation, resistance at high temperature, low-temperature anti-cracking and moisture susceptibility of porous asphalt mixture. The test results indicate that the porous asphalt mixture designed by the modified Bailey Method is of the characteristics of air void easier to control and superior performance.

Oven ageing is a set of procedure to simulate the accelerated effects of ageing on pavements structures. In this study, the effect of long-term oven ageing on porous asphalt mixture made with SBS modified binder was investigated. The resilient modulus, water permeability and air voids test results were the performance indicators used to evaluate the effects of ageing. The test results showed that, the resilient modulus of long term aged specimens was higher than those of unaged specimens. From the permeability test results, unaged SBS mixes exhibit lower coefficient permeability compared to the corresponding long-term oven age specimens. Most likely, ageing caused binder hardening, making the mix more difficult to compact and hence exhibited more continuous voids which in turn lead to higher permeability. In addition, the coefficient of permeability decreases as the binder content increased.

Marshall Stability

The objective of this paper is find the effect of using iron oxide as a filler on the Marshall stability, flow and the volumetric properties of HMA and compared the results with conventional HMA using limestone dust. Three blends were used: coarse, mid and fine with neat bitumen (AC 40-50). One aggregate type (crushed) with two types of fillers: limestone and iron oxide III (α- ) with three different filler content 6%, 8% and 10%. The Marshall mix design was conducted on the three blends and the optimum binder content is computed for each blend. The Marshall stability test results and the volumetric properties analysis showed that increasing the iron oxide content from 6% to 10%  increases the stability about 28%, 17% , 16% for the coarse , mid and fine mixtures respectively. This increment in stability of mixtures using iron oxide related to the increment in specific gravity of the mix (Gmb) by (1.3% to 1.5% about 30 to 50 kg/m3). On the other hand, the flow of mixtures is decreased about (5%) for mixes using iron oxide than the ones that used limestone as filler. The fine blend with 10% iron oxide exhibit the highest stability of 13.3 kN. While the coarse blend stability was 10 kN for the same filler type and content. Generally, the Marshall Test results of HMA using iron oxide as filler showed better resistance to plastic deformation, also produce denser HMA with higher stiffness. On the other hand, the volumetric properties analysis showed lesser values as compared with conventional mixture where the void in mineral aggregates and void filled with asphalt has decreased but within the acceptable limits.

Porous asphalt pavement is mainly used for parking lots which able to let water to drain through the pavement surface into a stone recharge bed and infiltrate into soils under the pavement. This study is to investigate the performance of seashell in porous asphalt and determine the image analysis. The seashell used in this study is cockle shell. The strength of seashell was determined through the Aggregate Impact Value Test (AIV) and Aggregate Crushing Value Test (ACV). The grade of bitumen used was grade 60/70. The porous asphalt volumetric properties was determined through Marshall Stablity Test. The permeability coefficient of sample that contain seashell as aggregate replacement was determined through Permeability Test. Generally, the results shows that the seashell’s percentage loss (AIV and ACV) is suitable use for porous asphalt mixture, where the percentage of loss for AIV and ACV was 27.84% and 7.65% respectively. Based on the Marshall Test, porous asphalt that containing seashell as aggregate replacement shows a different result, where it had lower stability value and it can increase the bulk density of porous asphalt mixture. Furthermore, the permeability coefficient also increase. The surface of seashell able to bond with bitumen. Lastly, the trend of VFA and VTM value is effected by the surface and position of seashell in the porous asphalt sample.
