Abstract

Purpose

In order to fully understand the properties of porous asphalt, investigation should be conducted from different point of views. This is from the fact that porous asphalt mixture designed with the same aggregate gradation and air void content can give different infiltration rate due to the different formation of the internal structure. Therefore, the purpose of this paper is to investigate the micro-structural properties and functional performance of porous asphalt simultaneously.

Design/methodology/approach

The aim is to develop imaging techniques to process and analyze the internal structure of porous asphalt mixture. A few parameters were established to analyze the air void properties and aggregate interlock within the gyratory compacted samples captured using a non-destructive scanning technique of X-ray computed tomography (CT) throughout the samples. The results were then compared with the functional performance in terms of permeability. Four aggregate gradations used in different countries, i.e. Malaysia, Australia, the USA and Singapore. The samples were tested for resilient modulus and permeability. Quantitative analysis of the microstructure was used to establish the relationships between the air void properties and aggregate interlock and the resilient modulus and permeability.

Findings

Based on the results, it was found that the micro-structural properties investigated have successfully described the internal structure formation and they reflect the results of resilient modulus and permeability. In addition, the imaging technique which includes the image processing and image analysis for internal structure quantification seems to be very useful and perform well with the X-ray CT images based on the reliable results obtained from the analysis.

Research limitations/implications

In this study, attention was limited to the study of internal structure of porous asphalt samples prepared in the laboratory using X-ray CT but can also be used to assess the quality of finished asphalt pavements by taking core samples for quantitative and qualitative analysis. The use of CT for material characterization presents a lot of possibilities in the future of asphalt concrete mix design.

Originality/value

Based on the validation process which includes comparisons between the values obtained from the image analysis and those from the performance test and it was found that the developed procedure satisfactorily assesses the air voids distribution and the aggregate interlock for this reason, it can be used.

Abstract

Purpose

Porous asphalt has been used for than 50 years, but it was originally developed in 1970 at Franklin institute in Philadelphia, Pennsylvania. By 1974 the first formalized procedure was created by the federal highway administration to design mixtures. Many researches on porous asphalt mixture have been conducted for the past two decades. However, there remains some concern about the potential adverse impacts of infiltrated surface water on the underlying groundwater. The purpose of this paper is to presents a short review on the application of porous asphalt pavement stormwater treatment.

Design/methodology/approach

In this paper, a critical review on history and benefits is presented followed by review of general studies of using porous asphalt pavement, and some recent scientific studies that examine potential contamination of soil and groundwater because of infiltration systems.

Findings

This paper indicates that porous asphalt pavement is more efficient than conventional pavements in terms of retaining pollutants, improving the quality of water and runoff while maintaining infiltration.

Originality/value

This paper may also help reduce land consumption by reducing the need for traditional storm-water management structures. However, on the other hand, the priority objectives which is minimizing increased flooding and pollution risks while increasing performance efficiency and enhancing local environmental quality-of-life is achieved.

Abstract

Malaysia is one of the developing countries which is progressing in terms of infrastructural facilities, but the country is facing a problem of having very low growth in population and this led to the frequent migration of workers with language proficiency to come to the country as foreign workers, language proficiency implications among which is causing injury to workers in the construction especially foreigners as they are getting it difficult to understand instruction during operations, safety guides and interpreting safety warning signs due to their low language proficiency. Because of this, the research aimed to reduce the rate of accident happening among the foreign workers and, therefore, the research sets three objectives: the research identified the common types of accidents faced by foreign workers due to language proficiency in construction sites, the research also investigated the extent to which language proficiency is affecting foreign workers and lastly provides an effective communication method that will help to minimise the rate of these types of accidents. The research found that language proficiency is causing several types of accidents that comes with different injury cases ranging from non-severe, severe and fatal once of about 44% of the total accident cases happening in the Malaysian construction industries.

Abstract

Purpose

This study aims to examine attitude, perceived behavioral and religiosity that influence Muslim consumers’ intention in patronizing at food premises with halal logo.

Design/methodology/approach

The data were collected from 450 respondents on random sampling basis. Quantitative analysis was conducted using SEM SMARTPLS version 3.3.

Findings

Based on the findings gathered using PLS analysis with n = 450, it was indicated that attitude, perceived behavioral control and religiosity significantly influence Muslim consumers’ intention on patronizing at food premise with halal logo.

Research limitations/implications

The data collection for the present study was limited to the respondents in Kuala Lumpur among Muslim consumers, and limited to 450 sample sizes.

Practical implications

The presence of halal logo should be crucial in attracting consumers due to the comprehensive meaning it brings.

Social implications

In the context of food premises, the results of the research suggest that the halal logo shown by the food premise seems to operate significantly in attracting Muslim consumers toward the food premises. Muslim consumers need to be nourished by proper Islamic teachings and have a good understanding of halal principle.

Originality/value

The halal logo of food premise concerns the Muslims. Muslim consumers are relying on surrogates in selecting the alternatives for packaged goods in Islamic marketing literature. However, it is little known how Muslims use indicators to select food premises when there is no halal logo.

Abstract

Purpose

Indonesia has the largest Muslim population in the world and represents a significant global-market opportunity for halal food producers. Surprisingly, halal-food consumption in Indonesia remains under-researched. Thus, this study aims to investigate the factors influencing consumers’ halal-food consumption, using an extended theory of planned behaviour (TPB) model.

Design/methodology/approach

Data were collected through a self-administered questionnaire distributed among 418 consumers in Surabaya, Indonesia. Multiple regression analysis was used to describe the TPB relationship and halal-food consumption.

Findings

This study successfully extended the TPB to include additional predictors: perceived awareness, habit, religious self-identity (RSI), moral obligations and trust to determine consumers’ intention in halal-food consumption. Attitudes, RSI and moral obligations were significant predictors of intention to consume halal food.

Practical implications

The findings can be used by the government and food producers to target specific factors, especially positive attitudes, RSI and moral obligations. Indonesia Ulama Council (Majelis Ulama Indonesia), the food industry and the media play a critical role in sustaining consumers’ positive attitude towards halal-food consumption. It is critical for food manufacturers to tailor their marketing strategies and consider promoting Islamic dietary rules when promoting their food products.

Originality/value

To the best of the authors’ knowledge, this study is one of the first attempts to investigate the determinants of halal-food consumption, using an extended TPB in Indonesia.

Abstract

Purpose

Food businesses provide Halal food to cater to the dietary requirements of Muslims, especially in communities with a growing number of the ethnic minority and at public institutions such as higher education establishments. A large and growing body of literature has investigated the purchasing and consumption behaviour of Halal food, and there are also studies that revealed consumers who do not support Halal food products on the grounds of animal welfare where animals were slaughtered without stunning. Thus, the purpose of this paper is to examine the predictors of purchasing intention of Halal food products and perceptions of animal welfare among Muslims and non-Muslim consumers of a public higher education institution.

Design/methodology/approach

An online questionnaire collected information on sociodemographic profiles and importance of Halal food. Descriptive statistics were used to determine the frequency of distribution of all sociodemographic characteristics. Multiple regression analyses were used to describe the theory of planned behaviour relationship and purchasing intention.

Findings

The regression model for all the respondents explained about 73 per cent of the variance of the intent to purchase Halal foods where R2 = 0.724 (adjusted R2 = 0.72). This was significantly different from zero F(3, 185) = 162.130, p < 0.001. Both Muslim and non-Muslim consumers’ attitudes were significant predictors of their purchasing intention of Halal foods (β = 0.87, p < 0.001). The implications of subjective norms and perceived behavioural control and the lack of influence from these predictors are discussed.

Originality/value

This study revealed that both Muslim and non-Muslim consumers agreed on the importance of animal welfare, but there exist differences in perceptions of animal welfare in Halal meat production. This research is of value to those working in regulatory and food service settings in understanding the differences and needs of consumers, and it contributes to a better understanding of the customers within a university setting.
