“…Engineers and road managers concerned with road construction have used asphalt as a cheaper alternative to cement concrete on pavement layers. Studies show that users must meet specific standards in using asphaltic concrete to avoid early failure of the constructed road [14][15][16][17][18][19][20][21]. They listed these criteria as mechanical and volumetric properties mostly.…”

This paper aims to create a model template systematically designed to manage, collate, and transform a plethora of raw asphalt concrete mix design data into a format conducive to simulated modeling. Using a Virtual Lab for simulation modeling is becoming popular in construction and requires data. Also, the gathered raw data in different forms becomes inputted into a well-developed format and framework for ease of usage. The paper achieved its goals by examining relevant literature to identify templates, criteria, principles, and standards for asphalt concrete mix design. Subsequently, it created a template with detailed attention to spreadsheet design and integrating essential parameters and criteria. The text then emphasized simplicity through comprehensive documentation and automating values within each table box using defined criteria. The paper also rigorously verified the template by inputting random asphalt data into the model template to validate the model's accuracy. Results show that the model template can manage physical test data from over a thousand past asphalt mix designs. Outcomes also show that rearranging data in the model produced analogous outputs. Findings from this study may serve as a baseline for those who intend to manage the data collected for asphalt mix design modeling.

“…Improving the quality of bitumen and asphalt concrete is a top priority in all nation-wide road industries [4]. Because the quality of asphalt concrete as a thermoplastic material is dictated by the properties of bitumen, the quality of bitumen greatly influences the quality and service life of road asphalt concrete pavements [5]. Polymer-modified bitumen is more resistant to thermal cracking and rutting.…”

This article presents studies on the modification of petroleum bitumen with polymer waste in the presence of vermiculite. An increase in temperature leads to an increase in the interaction of components, partial breakage of polyethylene and bitumen macromolecules, and the formation of radical-free valences. As a result, fragments of polyethylene and bitumen molecules react with each other, and the formation of qualitatively new structural formations occurs via the strong connection of polar and amorphous bitumen with nonpolar structurally viscous polyethylene. Domestically produced Kulantau vermiculite was used to ensure stable adhesion over a wide temperature range and increase the specific surface area, which acquired additional energy, resulting in an increase in the degree of adhesion to bitumen and increased durability of the binder with improved rheological characteristics. Because of the increased service life of road asphalt pavements, the use of the latter results in a considerable decrease in the cost of polymer-bitumen binders. Based on improved binder formulations, asphalt concrete exhibits excellent water resistance and strength at 50 °C (4.7 to 5.0 MPa). In summary, the modification of bitumen with polymer waste and vermiculite offers a promising avenue for improving the performance and longevity of asphalt pavements.

“…Currently, the use of waste materials to decrease the construction cost and increase the strength of materials has not been investigated extensively [5]. However, the usage of RAP in the East Java province is in the range of 20-30% [6]. The economic benefit of the utilization of RAP is that is cost efficient, and it preserves natural aggregates and asphalt [7].…”

This study presents the use of reclaimed asphalt pavement (RAP), and fly ash as artificial aggregate and filler in asphalt concrete. Because of the limited availability of natural materials, infrastructure development has become a concern. Therefore, it is necessary to reuse and recycle waste materials. One such innovation is artificial aggregates. The disadvantage of RAP is that its gradation exceeds the standard; its asphalt penetration and ductility exceed the requirements. The weaknesses of artificial aggregate are high water absorption, spherical shape, and low aggregate interlocking. In this study, the artificial aggregate was produced using the fly ash and alkali activator. Alkali activator consisted of Na2SiO3 and 8M NaOH at a ratio of 2.5. The mixtures containing different percentages of artificial aggregate (45, 55, 65, and 75%) were produced, and the fly ash filler content was 5%. Different tests including XRF, SEM, and Marshall tests were conducted. The artificial aggregate is hydrophilic owing to the high silica content; thus, it has high water absorption. This results in a low adhesion between the asphalt and aggregate. The best composition of asphalt concrete is 55% artificial aggregate, RAP, fly ash filler, and asphalt. The asphalt concrete containing artificial aggregate has high stability and is stiff and light. However, it requires a high asphalt content because of high water absorption. It is unsuitable for application in high traffic roads but suitable for medium traffic ones.
