Marshall Stability

Porous asphalt is a gap graded pavement that is 20% air voids which enables rainwater that falls on the road surface to flow through the pavement and into drainage on the side of the road. Porous asphalt has a high shear resistance and dries quickly but its stability is low, it is costly to maintain and needs replacing after only a short time. Despite these disadvantages, porous asphalt is still a good choice in area that experiences heavy annual rainfall. High Density Polyethylene (HDPE), an opaque plastic, is harder and stronger than porous asphalt with a tensile strength of 3100-5500 psi. It is resistant to high temperatures. This study aims to investigate the effect of various percentages of HDPE as an additive to produce an HDPE Asphalt Binder for porous asphalt pavement. Marshall parameters were determined based on the AAPA 2004 standard. It was found that 4% HDPE achieved a maximum stability value of 870 kg at the optimum asphalt content for porous asphalt pavement was 5.54%. Stability of porous asphalt pavement with optimum asphalt content value was 61.1% higher after the addition of HDPE. Thus, the use of HDPE as an additive in Asphalt Binder was able to increase the binding strength of the asphalt minimising the disadvantages of the low stability of traditional porous asphalt pavement.

The Second Variation

The quality of the road depends on the pavement, drainage conditions, and materials. For this reason, it is necessary to make innovations in improving the quality of road pavement, one of which is increasing the material. There are many types of pavements, one of which is porous asphalt pavement. Porous asphalt has many cavities that is easy for water to pass but has a low stability value with high           permeability. This research will utilize Low Density Poly Ethylene (LDPE), as an additive, CPO, and Pen 60/70 in a porous asphalt mixture. The purpose of this study was to determine the characteristics of the porous asphalt mixture by substituting LDPE and CPO for Pen 60/70. The method used in analyzing the characteristics of the porous asphalt mixture refers to the specifications of the Australis Asphalt Pavement Association (AAPA) (2014), with parameters Camtabro Loss (CL), Asphalt Flow Down (AFD), VIM, stability and flow. The gradation used in this study is an open gradation. This research was started from determining the value of Optimum Asphalt Content (KAO), with two variations, namely Variation 1 (1% LDPE, 10% CPO, 89% pen 60/70), variation 2 (5% LDPE, 10% CPO, 85% Pens 60/70). The KAO value of variation 1 is 5.03% and the second variation is 4.75%. After obtaining the KAO value, LDPE and CPO are substituted. The test results for the porous asphalt mixture for CL values were 34.12% and 27.07%, respectively; AFD value of 0.13% and 0.12%; for the VIM value of 14.90% and 19.03%; stability value 603.24 kg and 603.19 kg; and flow values are 5.03 mm and 4.80 mm. In general, the value obtained from the test meets the required requirements. However, the durability value of the mixture did not meet the requirements, namely 60.15% and 48.22%, with the condition >90%.

Although small amount of binder in asphalt concrete mixture may commonly range from 3.5 to 5.5% of total mixture as per many international specifications, it has a significant impact on the total cost of pavement construction. Therefore, this paper investigated the effects of five carbon nanotubes contents of 0.05%, 0.1%, 0.15%, 0.2%, 0.25% by asphalt weight as an additive material for binder on performance characteristics of asphalt mixtures. Performance properties of CNTs modified asphalt mixtures were investigated through the Marshall stability (MS) test, indirect tensile (IDT) test, static modulus (SM) test, wheel tracking (WT) test. The results indicated that asphalt mixtures with CNT modified binder can improve both the rutting performance, IDT strength and marshall stability of tested asphalt mixtures significantly at higher percentages of carbon nanotubes. However, the issue that should be considered is the construction cost of asphalt pavement. Based on the asphalt pavement structural analysis and construction cost, it can be concluded that an optimum CNT content of 0.1% by asphalt weight may be used as additive for asphalt binder in asphalt mixtures.

Nagan Raya District Government undertook the construction of roads, including the Poros Utama Road of Kuala Subdistrict. At the time of rain, in certain locations are still formed puddles above the surface of the asphalt. Therefore, it is necessary to evaluate the efficiency and duration of draining flow through the inlet on the road. The data required are the type, distance and dimensions of the existing inlet and the location map, the maximum daily annual rainfall data, cross and longitudinal sectional drawing. Calculations start by calculating the design flow of rainfall data processing. Furthermore, the calculation of the gutter flow as well as the efficiency and the inlet draining time. Based on calculations, the efficiency of the existing inlet in the form of a curb opening inlet is in the range between 4,93% to 6,51% with  0,64-3,92 minutes of draining time. This value indicates that the inlet on the road produces very low efficiency. Inlet is expected to drain all the water or 100% efficiency. The inundation disturbs the movement of the vehicle and affects the pavement resistance. Therefore, the flow of water above the road surface is expected not to create a puddle.

A new method to make SMA is developed by using SBS modified asphalt when the coarse aggregate steel slag and the fine basalt aggregate are selected respectively. The Mix Proportion is 1#(16-9.5mm, steel slag):2#(9.5-4.75mm, steel slag):3#(3-4.75mm, basalt):4#(3-0mm, basalt):5# (mineral powder)=38%:36%:8%:8%:10%.The optimal asphalt content (OAC) is 6.4%. The mass percentage of steel slag is reached 74%. The costs of this kind of high quality road material can be saved because the amount of asphalt is not increased. Based on Marshall Stability and Splitting Strength test, it is shown that the Marshall stability of SMA is 10.6 kN, dynamic stability is 7800, and tensile strength ratio is 89.2%. All above test values are superior to the standards in China's traffic regulations. The water permeability coefficient of SMA is 65, which means that SMA has an excellence Wear-Resistant performance. Therefore, SMA can increase the road useful life and reduce the road maintenance costs.
