Marshall Stability of Combination of Perlis Limestone and Granite in Hot Mix Asphalt

2024-06-07 , Mohd Badrul Hisyam Ab Manaf , Mohd. Mustafa Al Bakri Abdullah , Rafiza Abd Razak , Hassan M.R.M. , Muhamad K. , Muhammad Munsif Ahmad

Limestone is used in many countries for road pavement, such as Poland, USA and France. However, there are limitations in terms of mechanical and surface properties, but it has been used in some regions for years, particularly in Perlis, Malaysia, due to the need for a local source. The reason is that of caution of fear, in spite of wanting to explore the opportunities of Perlis limestone being used and understand the advantages and disadvantages of that aggregate. This study focused on the stability, flow, and volumetric by using a combination of Perlis limestone and granite in hot mixed asphalt (HMA) mixtures. The combination of Perlis Limestone and granite was analysed and tested to specification for roadworks by PWD, Malaysia. Furthermore, there will be a cost increment in road construction due to logistic and transportation problems in delivering imported granite aggregate from Kedah state. The result showed that HMA with less Perlis limestone aggregate showed a higher value of stability, flow and stiffness. As for the conclusion, HMA with more granite aggregate has better strength with less deformation compared with HMA with more Perlis limestone aggregate. HMA with more granite aggregate was also was stiffer, mainly due to the interlocking and frictional resistance of the aggregate due to the angularity and rougher surface of granite. However, since all the samples complied with the PWD specification, Perlis limestone proved it can be an alternative aggregate to be used in HMA.

2021-12-14 , Mohd Badrul Hisyam Ab Manaf , Mohd. Mustafa Al Bakri Abdullah , Razak R.A. , Ahmad M.M. , Rahim M.A. , Muda S.N.T.

Fly Ash (FA) is one of the sustainable materials to substitute Ordinary Portland Cement (OPC) was found commercialized in construction field but the usage in HMA pavement is limited. Thus, this study is important to promote FA as a sustainable filler instead of using OPC to reduce greenhouse gases. The primary aim is to investigate the Marshall Stability of HMA that incorporating of OPC and FA as filler. In addition, Optimum Bitumen Content (OBC) determination also conducted in this study. Marshall Stability test was conducted based on ASTM 2006 for both mixtures. The parameters gained from the test are the stability, flow, air void in mix (VIM), void filled bitumen (VFB) and stiffness being used to OBC. The OBC for HMA with OPC filler obtained is 5.06% meanwhile for HMA with FA is 4.79%. All Marshall Parameters was complied with of Malaysia Public Work Department (PWD) Standard for both mixtures. The HMA with FA filler give better results for all parameters. Based on OBC percentage, usage of asphalt binder was reduced at 0.29%. Thus, it was more economical if using FA compared with OPC as a filler. Furthermore, HMA with FA filler have better stability and strength as well as lesser deformation with HMA with OPC filler. For the overall, FA have huge potential in substituting other mineral filler to produce better quality of asphalt pavement.

The concrete structures that are built along the seaside often suffer from reduced service life due to inadequate durability against deterioration. This research reports the findings of concrete resistivity and quality using two Non-Destructive Testing (NDT) measures applied to Reinforced Geopolymer and Ordinary Portland Cement (OPC) concrete in the marine environment. In addition, the relationship between Reinforced Geopolymer and Reinforced OPC concrete was statistically discussed in-terms of strength and direction. The testing was carried out using a Proceeq Resipod Wenner 4-probe to measure Surface Resistivity (SR) and Ultrasonic Pulse Velocity (UPV), respectively. The testings were carried out on beam shaped samples of OPC and Geopolymer concrete that were immersed in seawater over a period of 90 days with similar curing condition. It was found from the present investigation that the maximum SR and maximum UPV values acquired for both the Reinforced OPC and Reinforced Geopolymer concrete are 2.73 kΩcm and 2.07 kΩcm, as well as 4.18 km/s and 4.05 km/s, respectively. It is apparent from the study that both concrete is comparable in terms of quality and surface resistivity.

Globally, the construction industry has become a complicated, critical, and exponentially developed leads to increase difficulties and required more innovative and better management system. This leads the organization to find a better solution to their management approach. The international standards in quality, environment, safety, security, supply chain, etc. have been combined to form a comprehensive system called integrated management system (IMS). By implementing a management system standard, organizations can benefit from global management experience and good practice, but the issues arise on the success factors and how they affect the performance of the company. There had been plenty of researches son IMS elsewhere, but this research was focusing on the construction industry in Malaysia in term of innovation performance. The approach is quantitative by disseminating questionnaire to the construction players in the northern region of Peninsular of Malaysia. The IMS's attributes, i.e. integration of IMS and integrated audits, are found to have positive relationship toward the innovation performance of an organization. The model moderately explained 52.8% proven that the attributes should be the focal point of the organization to increase their success factors in boosting their performance, especially in its innovation.

2020-06-10 , Mohd Badrul Hisyam Ab Manaf , Abdul Razak R. , Muhamad K. , Mustaqqim Abdul Rahim , Ahmad M.M. , Hao T.P.

The aim of this research is to determine the potential of geopolymer artificial aggregate as substitute for granite and limestone aggregates. Several aggregate property test such as aggregate impact test, aggregate crushing test, specific gravity test, water absorption test and the Los Angeles Abrasion test are done on the aggregates. The fly ash-based geopolymer artificial aggregate is produced through geopolymerisation by mixing fly ash with alkaline solution. The results show that the fly ash-based geopolymer artificial aggregate is lighter than natural aggregate in term of its specific gravity. The impact value and crushing value for fly ash-based geopolymer artificial aggregate are slightly higher compared to natural aggregate while the water absorption value is much higher compared to natural aggregate. Furthermore, the fly ash-based geopolymer artificial aggregate has higher value in the Los Angeles Abrasion. Overall, the fly ash-based geopolymer artificial aggregate can be considered as one of the construction materials in the roadwork pavement and in concrete as an alternative for coarse aggregate besides natural aggregate with more lightweight properties.
