Hot Mix Asphalt (HMA) is the most commonly used in Malaysia for highways, interstates and roads due to its flexibility, economical, strong and provide safe riding quality for road users. Over the years, the increase of damage on pavement roads in Malaysia has become a severe issue although the road did not achieve its design life. Hence, to reduce damage and defect, an improvised road pavement structures is needed. Various studies have been conducted to identify the new materials that can be used as a replacement in hot mix asphalt. In this research, the purpose is to evaluate the performance of eggshell as coarse aggregate replacement in hot mix asphalt. The gradation for aggregate used in this mixture is AC14. The weight for total mixing of the aggregates used is 1200g while the grade for bitumen is 60/70. The samples were mixed with eggshell in the various percentages of 0%, 5%, 10%, 15% and 20% by total weight of aggregate size 5mm. The laboratory tests carried out to determine the properties of aggregates included, aggregate impact value and aggregate crushing value. Besides, penetration and softening point were also performed to determine the properties of bitumen. Several types of test were conducted towards the samples, which are Marshall Test, Indirect Tensile Strength and Cantabro Test. The results exhibit that the conventional asphalt mixture is more effective than modified asphalt mixture. The replacement of eggshell as coarse aggregate was not enough improvement to the performance of asphalt pavement as the performance of conventional mixture is more stable than modified mixture.

Pavement construction is expected to support vehicle loads and be weather- and water-resistant. In tropical regions with high temperatures and high rainfall intensity, pavement design and construction must consider the effects of temperature. The addition of crumb rubber (CR) can improve the performance of asphalt concrete in response to vehicle loads and ambient temperature. Fiber-shaped CR can be mixed with the aggregate and bitumen in asphalt concrete. In this study, CR was added to the aggregate in a type of asphalt concrete for wearing courses known as hot mix asphalt (HMA). A series of tests were conducted using the Marshall standard or immersion and wheel tracking machine (WTM). CR was added to the HMA at 5%, 10%, 15%, and 20% in aggregate and further mixed with bitumen with 60/70 penetration grade. The additive materials increased the value of the Marshall stability compared to the virgin asphalt mixture. However, this result was not obtained in the WTM test; the addition of CR increased rutting compared to the asphalt mixture without additive. The addition of CR to HMA reduced the voids in the mix, and weakened the capacity of the asphalt concrete to support repeated vehicle wheel loading.

Marshall Stability

Stability is a measure of the strength of an asphalt mixture in resisting deformation due to loading. If a road construction structure cannot withstand the existing load, it will result in road damage that endangers road users. This study aims to improve the stability of the asphalt concrete mixture with the use of crumb rubber. Crumb rubber is used because it has good resistance and elasticity. The research was conducted experimentally by making test objects in the laboratory. In this study, five variations crumb rubber (2%, 4%, 6%, 8%, and 10% of the weight asphalt mixture) were carried out with the size of the powder retained on a 40 sieve. Marshall test and analysis of volumetric was carried out to determine the characteristics of the asphalt-concrete mixture. The results showed that the highest Marshall stability was obtained at 10% crumb rubber with a stability value of 1422 kg. The use of rubber powder can significantly increase the strength and quality of the asphalt-concrete mixture. Thus, crumb rubber can be used, and this percentage can be used as a reference in the manufacture of asphalt-concrete mixtures in order to obtain good road pavement quality.

The type and fineness of a filler significantly affect the performance of an asphalt mixture. There is a lack of specific research on the effects of filler fineness and dust from aggregates on the properties of epoxy asphalt (EA) mixtures. The effects of aggregate dust and mineral powder on the properties of an EA mixture were evaluated. These filler were tested to determine their fineness, specific surface area and mineral composition. The effects of these fillers on the EA mastic sample and mixture were evaluated. The morphology of the EA mastic samples was analyzed using scanning electron microscopy (SEM). The effects of the fillers on the Marshall stability, tensile strength and fatigue performance of the EA mixture were evaluated. The dust from the aggregates exhibited an even particle size distribution, and its average particle size was approximately 20% of that of the mineral powder. The SEM microanalysis showed that the EA mastic sample containing relatively fine dust formed a tight and dense interfacial bonding structure with the aggregate. The EA mixture sample containing filler composed of dust from aggregate had a significantly higher strength and longer fatigue life than that of the EA sample containing filler composed of mineral powder.

In this study, the compaction characteristics of recycled hot-mix asphalt (RHMA) were evaluated using the void content (VV), compaction energy index (CEI), slope of accumulated compaction energy (K), and lock point (LP). Then, the effects of the compaction parameters, including the gradation of the RHMA, reclaimed asphalt pavement (RAP) content, temperature of gyrations, and number of gyrations, on the compaction characteristics of RHMA were investigated. An orthogonal experiment was designed and the data collected were analyzed via range analysis; then, a regression model was generated relying on a quadratic polynomial. Furthermore, the regression model was used for the comparison and prediction of the mixture’s compactability during the material design. Finally, the compaction mechanism of RHMA was discussed from the perspective of the void content of RAP particles. The results showed that a finer aggregate gradation, a higher gyration temperature, a greater number of gyrations, and a higher RAP content were effective for increasing the compactability of RHMA. The range analysis results suggest that the gradation of RHMA has the greatest influence on compactability, followed by the RAP content. The RAP aggregate cannot diffuse to a new mixture completely, so the remained RAP particle reduces the void content of RHMA. Therefore, a higher RAP content up to 50% can help RHMA to achieve the designed void content with higher efficiency.

Abstract The bonding state of the asphalt layers in a road pavement structure significantly affects its fatigue life. These bondings, therefore, require detailed tests and optimization. In this paper, the analyses of the correlation between the results of laboratory static tests and the results of fatigue tests of asphalt mixture interlayer bondings were performed. The existence of the relationships between selected parameters was confirmed. In the future, the results of these analyses may allow for assessment of interlayer bondings’ fatigue life based on the results of quick and relatively easy static tests.
