The investigation studies the effect that varying the compactive effort has on the Marshall test properties of sand–asphalt–sulphur mixes (S–A–S mixes). An S–A–S mix containing a poorly graded river sand has been chosen for study, the proportions of sand, asphalt, and sulphur being 85:5:10 by weight.Another aspect of this study is to examine the effect of fly ash fines, an industrial waste, on S–A–S mixes. The resulting mix is named S–A–FA–S (sand – asphalt – fly ash – sulphur) and has a percentage composition of 80:5:5:10 by weight.It has been observed that the compactive effort has a definite effect on the Marshall test properties of S–A–S and S–A–FA–S mixes. In both cases, the stability rises initially and then falls with increasing compaction. S–A–FA–S mixes give higher stabilities and lesser air void values than S–A–S mixes at a particular level of compaction. It is concluded that 10 blows of compaction is optimum for S–A–S as well as S–A–FA–S mixes, as the beneficial effect after 10 blows is only marginal.

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.

The study investigates the use of waste glass as filler in asphalt concrete. Waste glass constitutes a significant proportion of the waste generated in both developed and developing countries. Successful utilization of the waste glass in asphalt will reduce the problem faced by environmental agencies at ensuring safe disposal of the non-biodegradable waste and may improve the asphalt properties. In the study, a waste glass in form of a filler was introduced into the asphalt mix at 8%, 10%, 12%, 14%, 16%, 18% and 20% of the total mix. The asphalt concrete samples with and without waste glass as filler were subjected to the Marshall test to determine the stability, flow, air voids, void in mix aggregate and void filled with bitumen. The Marshall test results show that stability increases when increasing glass filler up to 18%, although the values were lower than of the asphalt concrete without waste glass. This implies improved resistance to fatigue for higher waste glass content. Also, the flow increases with increasing glass filler, which implies the resistance to permanent deformation which did not improve. Generally, the introduction of waste glass in the asphalt concrete is environmentally friendly, and it will aid the sustainable management of waste glass.

AbstractThis study considers the use of polyethylene terephthalate (PET) waste for modifying asphalt concrete. In the study, the optimum bitumen content of asphalt concrete was replaced with 4%, 6%, 8%, 10%, 12%, 14% and 16% of PET waste; the Marshall test was conducted on the samples. A comparison of the unmodified and PET-modified asphalt concrete showed that the stability of the modified asphalt concrete was reduced. The maximum stability for the PET waste-modified asphalt concrete was recorded at a content of 12% PET waste. This gives about a 20.4% reduction in stability. The study reveals that the addition of PET waste to the asphalt concrete causes a reduction in the flow value except with the addition of 14% and 16 % waste. This implies that the introduction of PET waste could improve the permanent deformation resistance of asphalt, although there is concern about a reduction in fatigue resistance.

Abstract: Asphalt concrete pavement is depend on the type and composition of aggregate, asphalt, and filler being used. In this study, the aggregate used was an aggregate of Simeulue Island. In this Regency are difficult to find enough hard aggregate because the majority of the rocks there come from the process of particles mineral deposition, rest of the animals and plants which are found in the River (Aribowo, 2014). This research was conducted to find out the level of asphalt mixtures resistance using Simeulue aggregate with asphalt variation percentage of retona blend 55 and pen. 60/70 as a binder. This research begins with an examination of the physical properties of asphalt and aggregate next manufactured specimens based on gradations planning to determine of optimum asphalt content (OAC) with the overlapping method. From the results obtained, the elongation and flakiness index value did not meet the required specifications, those were 35.27% and 14.38%. The soundness aggregate against of Sodium and Magnesium sulfate (Mg2SO4) = 26.43% where is the maximum value required 12%. Aggregate wear value still meets the requirement, that was 23.84% 40%. OAC for AC-WC mixture using 100% RB, 100% Pen, 80% RB/ 20% Pen, 65% RB/ 35% Pen, 50% RB/ 50% Pen. was in the amount of 6.18%; 6.37%; 6.20%; 6.06% and 6.06%. From the Marshall test results in every OAC for all variations of immersion, showed the stability value using RB higher than by using Pen. 60/70. This was because asphalt RB can tie the Simeulue aggregate well compared to asphalt Pen. 60/70. The flow value was higher than the asphalt RB. VIM and MQ value at all immersion variation, using asphalt RB were higher than by using asphalt Pen. The durability value in all types of AC-WC mixture still meets the requirements of the Dept. PU (2010) ≥ 90%. While the durability value of 48-hour immersion already is under 90%.Abstrak: Perkerasan beton aspal sangat tergantung pada jenis dan komposisi agregat, aspal serta filler yang digunakan. Penelitian ini menggunakan agregat dari Kabupaten Simeulue. Pada Kabupaten ini sulit ditemukan agregat yang cukup keras karena mayoritas batuan yang ada berasal dari proses pengendapan partikel mineral, sisa hewan dan tanaman yang terdapat di sungai dan memiliki nilai pelapukan yang tinggi (Aribowo, 2014). Penelitian ini dilakukan untuk mengetahui tingkat ketahanan agregat Simeulue dengan variasi persentase aspal retona blend 55 dan aspal penetrasi 60/70 sebagai bahan pengikat dengan harapan dapat menghasilkan perkerasan yang lebih baik. Penelitian ini diawali dengan pemeriksaan sifat fisis aspal dan agregat selanjutnya dilakukan pembuatan benda uji berdasarkan gradasi rencana untuk menentukan kadar aspal optimum (KAO) dengan metode overlapping. Dari hasil penelitian agregat diperoleh nilai indeks kepipihan dan kelonjongan tidak memenuhi syarat yaitu sebesar 35,27% dan 14,38%. Kekekalan bentuk agregat terhadap larutan NaCl dan MgSO4 = 26,43% dimana nilai yang disyaratkan maksimal 12%. Untuk nilai keausan agregat masih memenuhi syarat yaitu sebesar 23,84% 40%. KAO campuran AC-WC menggunakan 100% RB, 100% Pen. 60/70, 80% RB/ 20% Pen, 65% RB/ 35% Pen, 50% Rb/ 50% Pen, masing-masing sebesar 6,18%; 6,37%; 6,20%; 6,06% dan 6,06%. Dari hasil uji Marshall pada setiap KAO untuk semua variasi rendaman, menujukkan nilai stabilitas menggunakan aspal RB lebih tinggi dibandingkan dengan Pen. 60/70. Hal ini dikarenakan aspal RB dapat mengikat agregat Simeulue dengan baik. Nilai flow lebih tinggi dibandingkan aspal RB. Untuk nilai VIM dan nilai MQ menggunakan aspal RB lebih tinggi dibandingkan dengan Pen. 60/70. Nilai durabilitas pertama pada semua jenis campuran masih memenuhi persyaratan Departemen PU (2010) ≥ 90%. Sedangkan nilai durabilitas kedua sudah berada di bawah 90%.
