Effect of Sugarcane Bagasse Ash as Filler in Hot Mix Asphalt

Hot Mix Asphalt (HMA) is a combination of asphalt and aggregates that will give durable road surface for pavement and is widely used in Malaysia. However, due to damages caused by excessive traffic loadings, the HMA pavement normally required frequently maintenance and rehabilitation works. Therefore in recent years, research on modification of HMA has tremendously increased in highway construction field using natural sources and recycling products such as rubber, plastic, anti-stripping agents, waste materials and etc. This study was conducted to evaluate the effect of sugarcane bagasse ash (SCBA) used as filler in HMA. Experimental laboratory were done to compare the properties of normal HMA sample with modified HMA sample using SCBA. Result obtained for both sample were compared to Malaysian Public Works Department (MPWD) specification. The laboratory result reveals that SCBA are effective in increasing the Marshall stability, flow and Resilient Modulus of normal HMA. The SCBA increases Marshall stability by 0.6%, flow 4.9% and Resilient Modulus 17.4% respectively of ordinary HMA and all test and analysis parameters for asphaltic concrete of SCBA sample comply with MPWD requirements. Therefore, SCBA has potential in modifying normal HMA.

With increasing interest in the use of hot mix asphalt in the paving industry, more studies in this field for improvement of hot mix asphalt properties seem to be necessary. Hence, the main objective of this study was to investigate the effect of sasobit® content as modified binder in hot mix asphalt. 60/70 penetration grade asphalt was separately modified with sasobit® at different concentrations ranging from 0% to 4.5%. The influence of sasobit® on the hot mix asphalt mixtures properties were detected through conventional tests i.e. penetration and softening point. In addition, the Marshall stability, abrasion loss, and resilient modulus were also examined. Results indicated that the hot mix asphalt containing Sasobit® additive has significant affect in terms of penetration and softening point. Furthermore, the addition of Sasobit® seemed to improve the stability, abrasion loss and modulus of stiffness.

Warm mix asphalt is an energy efficient mix that can be produced at lower temperature than the conventional hot mix asphalt, while maintaining the properties and performance required for the conventional hot mix asphalt. This paper presents a study in mix design of dense graded asphaltic concrete using a warm mix additive known as Cecabase RT. Type AC14 gradation for granite aggregates and bitumen of penetration type 60/70 were used for this study based on the Public Works Department of Malaysia’s Standard Specification for Road Works. The mixing temperature for the control sample AC14 mix without the additive was set at 160°C while for the mix using the Cecabase RT additive, the mixing temperature was set at 135°C. Marshall test procedure were then used to prepare the samples and volumetric properties were then evaluated to determine the optimum bitumen content. The optimum Cecabase RT additive content was then determined using samples prepared at the optimum bitumen content. The resilient modulus test was then carried out on the samples based on the repeated load indirect tensile test at temperatures of 25°C and 40°C at three different pulse repetition periods. From the analysis of the results, it was found that optimum bitumen content was at 4.9% while the optimum Cecabase RT additive content for the AC14 mix is 0.3%. The resilient modulus values obtained for the mix using Cecabase RT warm mix additive is higher than the control samples at both test temperatures and at all the pulse repetition period tested. It can be concluded that the use of Cecabase RT additive have the advantages of reducing the mixing temperature, thus producing a more energy efficient mix while improving the stiffness of the mix in terms of resilient modulus values, thus increasing a pavement load carrying capacity.

Reclaimed Asphalt Pavement (RAP) is old asphalt pavement that has been removed from a road by milling or full depth removal. The use of RAP in hot mix asphalt (HMA) eliminates the need to dispose old asphalt pavements and conserves asphalt binders and aggregates, resulting in significant cost savings and benefits to society. This paper presents a study on HMA with different RAP proportions carried out to evaluate the volumetric properties and performance of asphalt mixes containing different proportions of RAP. Marshall Mix Design Method was used to produce control mix (0% RAP) and asphalt mixes containing 15% RAP, 25% RAP and 35% RAP in accordance with Specifications for Road Works of Public Works Department, Malaysia for AC14 dense graded asphalt gradation. Volumetric analysis was performed to ensure that the result is compliance with specification requirements. The resilient modulus test was performed to measure the stiffness of the mixes while the Modified Lottman test was conducted to evaluate the moisture susceptibility of these mixes. The Hamburg wheel tracking test was used to evaluate the rutting performance of these mixes. The results obtained showed that there were no substantial difference in Marshall Properties, moisture susceptibility, resilient modulus and rutting resistance between asphalt mixes with RAP and the control mix. The test results indicated that recycled mixes performed as good as the performance of conventional HMA in terms of moisture susceptibility and resilient modulus. It is recommended that further research be carried out for asphalt mixes containing more than 35% RAP material.

Asphaltic concrete pavement is popular worldwide, but this type of pavement requires frequent maintenance and rehabilitation as it cannot cope up with the increasing number of traffic vehicles and loads. Therefore, modifying asphalt pavement to reduce the damages and defects is necessary, thereby enhancing the serviceability of pavement. This study presents the effect of waste cooking oil on asphalt mixture at different ageing conditions. A 60/70 penetration-grade asphalt binder was used, and 5% of this binder was replaced with untreated and treated waste cooking oil. Asphalt mixtures were prepared at the selected 5% optimum bitumen content and under two tests, i.e. Marshall stability and resilient modulus. The findings showed the better stability and resilient modulus of long-term aged samples incorporated with treated waste cooking oil than the unaged and short-term aged samples. The incorporation of untreated waste cooking oil caused reduced performance compared with the controlled and long-term aged samples. This result can be attributed to the high acid value of waste cooking oil. Therefore, treated waste cooking oil can be used as a binder replacement given its significantly higher performance at the mentioned ageing condition than the controlled mixture.

This paper presents the experimental results on the utilisation of Rice Hush Ash (RHA) as a replacement for mineral filler in asphaltic concrete pavement in Malaysia. Asphaltic concrete mixes containing RHA at different amounts and control specimens were prepared in accordance to Marshall Mix design, and their performance on stability, flow and bulk density were evaluated. Optimum binder content (OBC) and voids analysis were also conducted to compare performance of RHA at different contents. Results reveal that all RHA mixes have satisfied the Malaysian Public Works Department (JKR) specification on wearing course in regard with Marshall Stability and Flow, especially RHA-75. This material is potentially to be used as partial or fully substitution of mineral filler (stone dust) in pavement construction.
