Abstract

Damage type that common happens to Asphalt Concrete Wearing Course (AC-WC) is the crack due to fatigue. This research objective is to analyze the performance of the stiffness, fatigue, static creep and dynamic creep of the AC-WC hot asphalt mix to optimum asphalt content. The research was conducted at Road Laboratory of the Civil Engineering Department, Udayana University. The mixture was produced in hotmix and tested with Marshall procedure. The method used in testing stiffness, fatigue and creep testing refers to the British Standard. The equipment that is used is the Dynapave UTM 30. Based on the research it was found out that the optimum asphalt content (OAC) of AC-WC mix was 6.05%. The ITSM value at temperature of 10oC, 20oC, 30oC were 6175 MPa, 4356 MPa, 3790 MPa, respectively. The fatigue performance on dynamic loading at pressure of 300 kPa failed at 37,401 times of load repetition, at pressure of 500 kPa failed at 15,513 times of load repetition, at pressure of 700 kPa failed at 3,866 times of load repetition. The static creep performance was 20.84 MPa. The stiffness of creep dynamic was 13.69 MPa. In general comparison, between the test result of the static creep and dynamic creep shows that with dynamic load the sample gave bigger strain so its stiffness becomes smaller, compared to the static load. In other words, the dynamic load causes bigger deformation.

Abstract

One of asphalt mixture being developed is Cold Bituminous Emulsion Mixtures (CBEMs) that its performances need to be improved. Within this experiment it is done by adding epoxy. The objective of this study was to analyze the characteristic of CBEMs with and without epoxy. Epoxy variation was 1%, 3%, and 6% by weight of residual bitumen. The epoxy was mix with hardener in ratio 1:3, then mixed with bituminous emulsion. Epoxy was added into the Optimum Residual Bitumen Content (ORBC) of 7,5%. The aggregate was dampened with water first then mixed with emulsion that had been added with epoxy, then compacted. It was found that CBEMs added with 1% and 3% epoxy met the specifications, however CBEMs with 6% of epoxy did not, because the porosity was 17,83% (spec.5%-10%). The soaked stability of the mixture without and with epoxy 3% was 1177,02 kg and 1416,47 kg. Addition of 3% epoxy increase soaked stability up to 20%. In stiffness, creep, and fatigue tests, CBEMs without epoxy compared by CBEMs with 3% of epoxy, respectively gave result: stiffness 1854 MPa: 959 MPa (-48,27%); strain at 106 loads repetition (Nf) was 78,09 µ?: 93,22 µ? (+19,38%); Nf at strain 100 µ? was 358.897 times: 539.585 times (+50,35%); creep slope was 23,752: 39,939 (sample was collapsed before 3600 loads repetition). However, epoxy caused the mix stiffer hence increase the porosity of the mixture to 20%. It is suggested to reduce the hardener content of the epoxy, to manitain workability and reduce porosity.

Abstract

ABSTRACTOne problem of the environment is the increasing amount of plastic waste especially thin plastic bag and other thin plastic packaging, therefore effort is needed to utilize those plastic waste. Within this experiment thin plastic waste was use on the production of road asphalt mixture. The aim of this experiment was: to know the effectivity of the plastic coating onto the aggregate; the properties of the aggregate coated with thin waste plastic; and the Marshall characteristic of HRS-WC. Waste thin plastic waste was manually cut with size: <10mm and 10-20mm. The aggregate was heated, then plastic waste was spreaded, mixed, added with optimum asphalt content (OAC), evenly mixed and compacted 2x75 Marshall blow. Plastic coating was found only effective (observed visually) on the coarse aggregate using wider plastic size 10-20mm. Samples of HRS-WC were made with aggregate coated with plastic at OAC; OAC-0.5%; and OAC-1%. It was obtained that: the OAC was 7.55%. For 100% coating the coarse aggregate the amount of plastic needed was 30gram (8.6% by weight of total aggregate), and 15gram to coat 50%. The difference on Marshall Characteristic without and with added plastic was not significant and difficulties was experienced to meet volumetric properties, nontheles there was increase in Marshall stability. It was found that, the Marshall stability, flow, Marshall Quotient, VIM, VMA, and VFB on OAC with 50% plastic coating on the coarse aggregate, were consecutively: 1017.35 kg; 3.05mm; 333.69 kg/mm; 298.94 kg/mm; 4.288%; and 18.055%. Meanwhile on 100% coating, consecutively: 1075.07 kg; 3.59mm; 298.94 kg/mm; 4.037%; 17.462%; dan 76.90%.

Abstract

Utilization of waste aggregates for construction industry had been encouraged in line with increasing pressures to reduce exploration of natural aggregates. One alternative material that can be used as masonry block unit is the construction demolition waste (CDW) with asphalt as the binder (CDW block). The objective of this paper is to produce CDW block with a performance equal to the concrete block commonly used in the United Kingdom with a compressive strength between 3.5 MPa and 7 MPa and the specific creep strain less than 100 microstrain. The CDW block requires suitable particle size proportion, in order to obtain satisfactory results and to meet the demand of using minimum bitumen content and low compaction level. The CDW block requires sufficient heat curing to harden the asphalt. It was found that CDW materials were a very suitable material to be used for making CDW blocks. Compaction level of 2 MPa and curing regime of 200°C for 24 hours were sufficient and gave satisfactory results.

Abstract. This paper described about masonry wall building blocks that incorporate waste aggregate materials, namely steel slag, crushed glass, and coal fly ash. The binder used was 50 pen bitumen. The investigation was carried out at the University of Leeds United Kingdom (UK). The samples were produced by hot mixing the waste aggregates, compacting by static compaction, then applying heat curing to the compacted samples to harden the bitumen binder. The objective of the investigation was mainly to evaluate the building blocks compressive strength and volume stability (expansion and shrinkage) due to moisture and thermal exposure. It was found that the sample's compressive strength was comparable to concrete block commonly used in the UK. The volume stability of the sample was found largely irreversible due to moisture exposure, but highly reversible due to heat conditioning. The samples gave coefficient of thermal expansion comparable to clay bricks and concrete masonry blocks, and coefficient of moisture expansion similar to clay bricks. The blocks are suggested to be used for internal walls and are not exposed to outdoor weather, and should be protected with sand cement mix plaster.Abstrak. Paper ini menguraikan tentang blok pasangan dinding yang menggunakan agregat dari bahan bekas yaitu: steel slag, pecahan kaca, dan abu terbang batu bara. Bahan perekat yang dipergunakan adalah aspal penetrasi 50. Penelitian dilaksanakan di Leeds University United Kingdom (UK). Penggunaan bahan bekas dalam industri bangunan sudah digalakkan sejalan dengan strategi. Sampel diproduksi dengan dicampur secara panas, dipadatkan dengan pemadatan statis, dan dipanaskan untuk mengeraskan perekat aspal. Tujuan dari penelitian ini utamanya adalah untuk mengevaluasi kuat tekan dan stabilitas volume (pengembangan dan penyusutan) dari blok bahan dinding akibat terekspos air dan panas. Ditemukan bahwa kuat tekan sampel sebanding dengan jenis bata beton yang umum dipergunakan di Inggris. Stabilitas volume sampel dalam porsi besar tidak kembali ke kondisi semula akibat terekspos air, namun dapat kembali ke volume semula akibat terekspos panas. Sampel memberikan koefisien ekspansi termal yang sebanding dengan bata tanah liat dan bata beton, dan memberikan koefisien pengembangan lembab mirip seperti bata tanah liat. Blok pasangan yang diteliti ini, disarankan untuk digunakan sebagai dinding di dalam ruangan yang tidak terpapar cuaca luar dan diberi pelindung plesteran pasir-semen.

Abstract

AbstrakCold Paving Hot Mix Asbuton (CPHMA) adalah campuran yang terdiri dari agregat, asbuton butir, bahan peremaja dan bahan tambah lain yang dicampur panas dipadatkan dingin (pada temperatur ruang 30°C). Karakteristik campuran dipengaruhi temperatur pemadatan. Tujuan penelitian ini adalah untuk memperoleh: kadar aspal residu optimum, temperatur pemadatan ideal dan perbandingan karakteristik CPHMA yang dipadatkan secara dingin dan panas. Pemadatan dilakukan pada suhu 30°C, 60°C, 90°C, 120°C, dan 150°C. Diperoleh hasil, kadar aspal residu optimum 7 %; suhu pemadatan ideal 90°C. Pemadatan dibawah suhu 90°C memberikan porositas lebih tinggi berkisar antara (4,86-5,53)% namun masih memenuhi spesifikasi (4-10%). Pemadatan diatas suhu 90°C memberikan porositas antara (2,04-3.0)%, yang lebih rendah dari spesifikasi. CPHMA yang dipadatkan pada suhu ideal 90°C memberikan karakteristik Marshall, cantabro, kekakuan (stiffness), rangkak (creep), dan kelelahan (fatigue) lebih baik dibandingkan dengan CPHMA yang dipadatkan dingin.AbstractCold Paving Hot Mix Asbuton (CPHMA) is a mixture that consists of aggregates, asbuton particles, rejuvenating materials and other added materials, which were hot mixed and compacted cold (at ambient temperature 30°C). The characteristics of the mixture were affected by compaction temperatures. The objectives of this study were to obtain: residual optimum asphalt content; ideal compaction temperature and characteristics comparison of CPHMA compacted cold and hot. Compaction were carried out at 30°C, 60°C, 90°C, 120°C and 150°C. It was obtained that the optimum residual asphalt content for CPHMA mixture was 7% and the ideal compaction temperature was 90°C. Compaction at temperature lower than 90°C gave higher porosity, i.e between (4.86-5.53)%, nonetheless still met specification (4-10)%. Compaction at higher than 90°C gave porosity between (2.04-3.0)% which were lower than the specification. CPHMA compacted at ideal 90°C gave better Marshall characteristics, cantabro, stiffness, creep, and fatigue, compared to the cold compacted CPHMA.
