Abstract

This paper describes investigation on the performances of cold asphalt emulsion mixes (CAEMs). The type of emulsion used was a cationic asphalt emulsion. The investigation was carried out at Leeds University, United Kingdom (UK). The objective of the experiments was to evaluate and to improve the performances of cold mixes and compared with hot mixes. For optimising the performances of the cold mixes, a target porosity of five to ten percent and indirect tensile stiffness modulus (ITSM) value of 2000 MPa was selected, suitable for low to medium trafficked roads. A simplified mix design procedure was used for producing the cold mixes. It was found that when properly designed, at full curing conditions, the stiffness (ITSM) of CAEMs were found to be very comparable to those of hot mixes. Test results also show that the addition of cement in the amount of one to two percent by mass of aggregates significantly improved the mechanical performance of cold asphalt mixes.

Abstract

This paper described an investigation and evaluation which was carried out in the United Kingdom-UK, on the properties of masonry building block materials that incorporate waste materials, namely: steel slag, crushed glass, coal fly ash, rice husk ash (RHA), incinerator sewage sludge ash (ISSA), municipal solid waste incinerator bottom ash (MSWIBA) or shortened as IBA, bound with bitumen or asphalt, named as Bitublock. The binder used was 50 pen bitumen. The properties of the blocks evaluated were: compressive strength, density, porosity, initial rate of suction (IRS), creep, and volume stability. It was found that the Bitublock performance can be improved by optimizing porosity and curing regime. Compaction level of 2 MPa and curing regime of 200°C for 24 hours gave satisfactory bitublock performances that at least comparable to concrete block found in the United Kingdom (UK). The Volume stability (expansion) of the unit is affected by environment relative humidity.

Abstract

This paper covers results of laboratory investigations on the volume stability of masonry units incorporating waste materials bound with bitumen (Bitublocks), due to moisture adsorption, thermal exposure and vacuum saturation. The materials used were steel slag, crushed glass, coal fly ash, and 50 pen bitumen. The samples were produced in hot mix method, compacted, then exposed to moist and temperature. It was found that moisture adsorption from the environment caused the Bitublock to expand. The samples with less intense curing regime experienced lower expansion and became stable faster, and vice versa. Under thermal condition (at 70°C), the samples with less intense curing regime underwent higher expansion, and vice versa. They were also highly reversible. Their volume stability was found unique under water exposure. The expansion on first vacuum saturation cycle was irreversible, then largely reversible on the following cycles.

Abstract

Masks are essential for preventing people from breathing in dangerous compounds and airborne pollutants. On the other hand, incorrect mask disposal presents a serious environmental risk. Medical masks are mostly made of polypropylene and are formed of three layers: a central layer of melt-blown material, an outer layer of waterproof non-woven fabric, and an interior layer. This research aims to determine the effect of medical mask waste fiber on the rheological characteristics of asphalt. In terms of the rheological characteristics of asphalt, the addition of asphalt will decrease the penetration, ductility, specific gravity, and lost on heating, and increase the viscosity, softening point, and flash point. The positive impact is that the inclusion of mask waste results in increased asphalt hardness, enhancing resistance to rutting. On the other hand, the negative impact is that the inclusion of masking waste will reduce the resistance to cracking due to the reduced elasticity.

Abstract

According to the Ministry of Environment and Forestry, total national waste in 2021 will reach 68,5 million tons. Of that amount, 17%, or around 11,6 million tonnes, was contributed by plastic waste. Fruit wrapping (foam nets) and thin plastic packaging are examples of plastic waste often found in society. This research will make fruit wrapping nets and use thin plastic packaging into plastic blocks for wall-building material (PBWBM). This research aims to determine the melting temperature, mixture proportions, and solidification temperature and analyze the characteristics of the plastic blocks using fruit wrapping nets, thin plastic packaging, waste motor oil, and rice husk ash filling materials. The PBWBM consisted of three types of samples, namely Mixture A (fruit wrapping net + waste motor oil), Mixture B (fruit wrapping net + used thin plastic packaging + waste motor oil), and Mixture C (fruit wrapping net + waste motor oil + rice husk ash). The right temperature for melting fruit wrapping nets and using thin plastic packaging with waste motor oil is 200 oC. The recommended PBWBM mixture proportion based on trial and error is 800 grams of fruit wrapping net and 600 grams of waste motor oil (compressive strength test results). The ideal compaction temperature ranges from 110 oC-125 oC, IRS test results range from 0,0135-0,0252 kg/m2.minute, water absorption content values range from 0,0281-0,0688%, and porosity values range from 0,720-2,006%. The compressive strength value without immersion was obtained in the range 29,826-42,063 kg/cm2, and the compressive strength value with immersion was obtained in the range 25,728-40,023 kg/cm2. The compressive strength values for the three types of PBWBM have reached the minimum average compressive strength based on BSN 1989 (≥ 25 kg/cm2).
