Abstract

Waste thin plastic wrap in the form of crackle plastic, aluminium coated plastic, other thin plastics, have not yet been widely utilized. Limited un-organic rubish collector willing to receive it. The price is also relatively low, hence it is not attractive for it’s collection. This material can be used as a plastic wall block (PWB) with combination of those waste plastic, waste cooking oil (wco), without and with rice husk ash filling. The objective was to analyze the properties of the PWB. There were four mixed produced namely: Mix A (50% crackle plastic+25% aluminium coated plastic+25% other thin plastics and wco); Mix B: (75% crackle plastic+12.5% aluminium coated plastic+12.5% other thin plastics and wco). Mix C: similar to Mix A, added with rice husk ash. Mix D, similar to mix B, added with rice husk filling. The samples were produced by heating the wco at 200 °C, the the waste plastic were melted without and wirh rice husk ash, then pressed at around 576.02 kg. The mixture were pressed at 100-125 °C. It was obtained that the density: 0.796 – 0.817gr/cm3, porosity: 0.018 – 0.096, IRS: 0.015 – 0.045 kg/cm2.minute, absorption: 0.044– 0.169%. The unsoaked compressive strength was 14.51 – 27.285  kg/cm2. The soaked one was 13.005 – 23.205. In general the compressive strength obtained was within higher range of low quality block experimented by researchers in some part of the world with sttength between 2.55-15.2 kg/cm2.

Abstract

Diperlukan upaya untuk memanfaatkan bekas bongkaran bangunan untuk blok bahan pasangan dinding (BBPD) dan penggunaan lateks sebagai pengganti semen. Tujuan penelitian ini adalah untuk untuk menganalisis karakteristik BBPD. Agregat dari bekas bongkaran bangunan dan beton bekas dipecahkan secara manual, kemudian diayak dan diproporsikan dengan cara coba-coba untuk mendapat bentuk sampel yang stabil dan kompak. Kadar lateks dan tingkat pemadatan divariasi. Material dicampur rata dan dipadatkan, kemudian di oven pada suhu 40o C selama ± 6 x 24 jam sampai berat konstan. Dibuat juga sampel yang di kondisikan pada suhu ruang dan dites pada umur yang bervariasi. Didapatkan kadar residu lateks minimun yang diperlukan adalah 5,56% dari berat total agregat. Kuat tekan BBPD dapat mencapai 34,95 kg/cm2.

Abstract

This study aims to analyze the effect of asphalt heating duration and asphalt mixture aging simulation on the performance of stiffness, creep, and fatigue of road pavements. The research was conducted experimentally, with samples obtained from 30 asphalt core drillings in the field, each subjected to six treatments consisting of V1 (1 hour), V2 (2 hours), V3 (3 hours), V4 (6 hours), V5 (7 hours), and V6 (8 hours), all at a temperature of 155°C. Each variation consisted of five samples tested for asphalt properties, including penetration (SNI 2456:2011), ductility (SNI 2432:2011), viscosity (SNI 7729:2011), softening point (SNI 2434:2011), flash point (SNI 2433:2011), and fire point (SNI 2433:2011). The results showed that asphalt properties varied significantly with heating duration (V1–V6), indicating that longer heating had a clear impact on asphalt characteristics. The penetration values obtained for V1 to V6 were 67.17, 64.6, 62.4, 62.2, 58.75, and 49.5, respectively, while the viscosity values were 211 seconds, 206 seconds, 201 seconds, 198 seconds, 193 seconds, and 190 seconds. The softening points were 41.5°C, 43.5°C, 44.5°C, 45°C, 46°C, and 47°C, while the flash points were 318°C, 325°C, 329°C, 330°C, 332°C, and 335°C. The fire points were 330°C, 332°C, 335°C, 340°C, 345°C, and 350°C. The stability values of the mixture increased with heating duration, reaching 1883.5 kg, 2040.5 kg, 2130.2 kg, 2175.0 kg, 2197.4 kg, and 3254.4 kg. Conversely, the flow values decreased, becoming 3.81 mm, 3.05 mm, 2.79 mm, 2.29 mm, 2.16 mm, and 1.91 mm. The average Marshall quotient values for each heating variation were 494.36 kg/mm, 669.45 kg/mm, 762.41 kg/mm, 951.45 kg/mm, 1017.81 kg/mm, and 1235.91 kg/mm. This study can help optimize asphalt heating duration to improve pavement quality and durability. The findings also have the potential to serve as a basis for refining standards and policies in the design and maintenance of more resilient road infrastructure.

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.
