Published: February 2021

Abstract
Construction activities significantly increase the amount of sediment loss from sites due to erosion. Hence, governments are implementing environmental regulations, including the Erosion and Sediment Control Plan (ESCP), to reduce the construction industry’s impact on the environment. Prior studies suggest that effective enforcement by government bodies is crucial to ensure proper ESCP implementation. Therefore, this study aims to identify the success factors and challenges of enforcing ESCP in practice. To achieve that objective, this study employs a qualitative research technique that compares ESCP guidelines between countries. The significant results include: (a) the challenges are in the aspect of the hierarchy of authorities, lack of information in the guidelines, and enforcement that are lenient; and (b) the success factors include the elements of having detailed information in guidelines, a suitable period is given to all parties, and frequent inspections. These findings can assist researchers and government bodies to develop strategies to enforce ESCP better. The development of better strategies would help improve the success of ESCP implementation. This paper contributes to the body of knowledge in analyzing enforcement strategies in existing guidelines and standards for ESCP.

Abstract
Concrete debris and bottom ash has been identified as the potential materials to be used in construction industry. This would certainly reduce wastage produced from construction and demolition (C&D) activities and bottom ash from the power plant. However, the concrete debris waste and the bottom ash are been neither tested nor proven to be feasible in the construction of railway track. This paper will discuss the potential usage of concrete debris collected from destruction site and also the bottom ash waste from Coal Energy Power Plant. Currently, neither concrete debris nor bottom ash is used in railway construction. The main objective of this study is to analyse the engineering properties of bottom ash and concrete debris along with the conventional ballast to verify whether the traditional material can be replaced or otherwise. Experiments such as the sieve analysis test, Los Angeles abrasion test, aggregate impact value test and the aggregate crushing value test were conducted to measure the properties. The engineering properties tested in this research are the hardness, toughness and resistance towards impact and crushing of ballast. In terms of gradation, particle size distribution curve was plotted and compared in this research. It was found that the mixture of concrete debris and track ballast in the proportion of 50:50 each has brought some improvement to the properties and tend to behave close to the existing track ballast. The mixture of concrete debris and track ballast also shows that its crushing resistance is better than the existing track ballast. In conclusion, both the waste materials used in this research is highly potential to partially complement traditional material of track ballast.

Abstract
Stone mastic asphalt (SMA) is a type of gap graded asphalt mixture. Due to large difference between the gap of large and small size aggregate, this type of mixture suffers a few drawbacks such as low resistance towards permanent deformation. Thus, the usage of ecofriendly and sustainable additive is crucial in enhancing the performance of SMA. Thus, this study is utilizing various amount of eggshell powder as asphalt modifier. Among the tests involve to evaluate the stress-strain characteristic of modified SMA are Resilient Modulus Test and Dynamic Creep Test. From the test, it shows that the addition of 4% eggshell powder produces the highest value of resilient modulus and lowest value of dynamic creep for SMA. In conclusion, this study proves that the eggshell powder is capable in enhancing the performance of SMA especially in terms of permanent deformation resistance.

Abstract
The pavement industry relies greatly on this conventional material in constructing the road. However, the shortage of the mined material has led to the need of finding alternative with local materials to partially substitute the asphalt components. The conventional pavement industry also contributed to thermal and greenhouse emission resulting from the mining activities. In addition, throughout the year, the amount of construction and demolition (C&D) waste generated from civil construction activities particularly in Malaysia is increasing in alarming rate. Recycling the C&D waste specifically in bricks is viewed as reasonable potential as aggregate modifier in the impulse for greener and sustainable asphalt pavement production. In this paper, recycled crushed bricks (RCB) is introduced to bituminous wearing course as partial replacement for coarse aggregates. The coarse aggregate is partially replaced with RCB in proportions of 0%, 10%, 20%, 30% and 40% by weight. This study summarizes the results of laboratory evaluation of Los Angeles Abrasion Value, Aggregate Crushing Value and Marshall Test. Results show that asphaltic concrete modified with 10% RCB has the lowest abrasion and crushing values which were 20.2% and 30% respectively. Similarly, the mix has the highest Marshall Stability and lowest flow which 15.61 kN and 3.37 mm respectively. Thus, partial replacement of coarse aggregates with 10% RCB in bituminous mix is suitable to be used in wearing course and can be used as alternative material in bituminous mix to reduce the dependency on natural aggregates and utilize the C&D waste efficiently.

Abstract
Urban cities in Malaysia are highly vulnerable to flash floods due to improper drainage system and the impermeable road surface. The Pervious Concrete (PC) Pavement for urban water management indicates the implementation of this system shows promising results to reduce flash flood volume and among the mitigation that can be applied is by adopting the permeable pavement systems. This was based on a case study of Sponge City in China. Since the properties normally consist of coarse aggregate only / or less fine aggregate to fill in the void structure. Regardless of the high advantage of these systems to reduce the flooding impact, this permeable pavement is known for its lower strength. Due to this fact, it is rare and impossible for this permeable pavement to be utilized at the main road and highway. Whereas, currently in Malaysia, the permeable concrete is only accustomed to light traffic loadings such as walkways and car park. This paper was discussing the way to improve the strength properties of PC pavements with a focus on sustainable development.

Published: February 2021

AbstractThe partial substitution of bio-binder for petroleum asphalt binder is possible in the pavement application. Biomass commonly employed renewable energy origin is normally a raw substance used for the production of bio-binder, which includes palm oil, microalgae, soybean oil, vegetable oil, engine oil residue, grape remains, swine waste and many others. This review addresses the diverse bio-oils produced from different biomasses, followed by the properties of bio-oils and performance of bio-asphalt. This review also emphasises on the hydrothermal processing of biomass and the parameters affecting the quality and quantity of the yield for the use in asphalt. Notably, hydrothermal processing is a crucial thermochemical converting procedure employed on biomass into materials or biofuel. Following the aimed products, such as bio-gas, bio-oil, or bio-carbon, the variables selected during the operation (pressure, temperature, and time) is very critical. A notable impact has been placed in assessing a wide range of biomass supplies for hydrothermal processing due to the suitability of the operation for any biomass category. Provided that the majority of the biomass supplies are highly moisturised, the hydrothermal operation is the most efficacious method of processing the supplies. On the other hand, the physical, and rheological properties of the biobinders or bio-asphalt were highlighted and discussed. Majority of the bio-oils were found to improve the low-temperature performance, but reduce the resistance against deformation at high temperature of the bio-asphalt. It was also suggested that further studies should emphasise on the interaction between the asphalt matrix and bio-oils added at the microscale.

Abstract
In the recent years, the use of reclaimed asphalt pavement (RAP) in the pavement has become inevitable for economic and environmental reasons. However, the brittleness property of aged asphalt in the RAP restrict its usage in a high percentage. Nevertheless, the rejuvenators are introduced into the mixtures to reverse the effect of ageing processes, decrease the stiffness and increase the workability of RAP mixture. In the present research, various percentages of PelletRAP rejuvenator were added to 100% of RAP mixtures. The performance characteristics of rejuvenated mixtures were investigated via resilient modulus (MR), dynamic creep, and wheel tracking tests. The results showed that when the PelletRAP was included into the mixture, the MR values and the creep stiffness modulus (CSM) decreased, while the permanent creep, the creep strain slope (CSS) and the rutting depth increased. However, all the rejuvenated mixtures exhibited better results than that of virgin mixture. Such a trend of findings suggested that PelletRAP can be used as a rejuvenator without a negative effect on the high-temperature performance of asphalt mixtures.

Abstract
Titanium dioxide (TiO2) three-dimensional (3D) nanostructure has been prepared and doped with vanadium (V) using a solution immersion method. The resultant material exhibited improved performance in the role of the sensing element in resistive-type humidity sensor. The improvement is attributed to the arrangement of the nanorod structure which appears to be more closely packed in the V-doped TiO2 when compared to the undoped TiO2. Another possible reason is due to the increased of defect sites, namely oxygen vacancies of the V-doped sample which enhance the dissociation of the adsorbed water molecules.

Abstract
Traffic congestion has become a serious issue due to the growing number of vehicles in Malaysia. Traffic light control system is widely used to control the flow of road junction. Currently, most of the traffic light system used pre-time and count down timers to control traffic flow. Due to the fixed-time setting, often the system unable to handle unexpected heavy traffic flows and cause traffic jam. Thus, there is a need of adaptive traffic signals which are able to do real time monitoring to control traffic light signal based on traffic density. This study proposed an adaptive traffic light control system that uses image processing and image matching technique in controlling the traffic in an effective manner by taking images of each lane at a junction. The density of traffic in the images at each junction are compared. Results show that more time are allocated for the vehicles on the densest road to pass compared to other less dense road. Edge operation detector is used to detect the density of traffic at each lane. In this study, a comparison study was carried out by applying five different edge detectors namely Roberts, Sobel, Log, Canny and active contour. Among these detectors, Canny edge operation detector has found to be the best as it could extract actual edges with average time of 0.453 second.
