Maximizing the Application of RAP in Asphalt Concrete Pavements

Asphalt concrete pavements (ACP) are designed and built to last for a limited period of time, usually between 15 and 35 years. After this period, if the surface layer cannot be repaired, it must be completely removed and replaced. One way of disposing old ACP materials is to dispose of them at a designated landfill or dump site.It implies that pavements should be able to withstand high and how to limit their effects with different additives. was used to evaluate the effect of deicers on the asphalt concrete .(PDF) Evaluation of the effect of aggregate mineralogy on the

Development and performance evaluation of epoxy asphalt concrete

In cold regions, fibers were also used as additives to improve the fracture performance of asphalt concrete, to reduce or eliminate the occurrence and expansion of the crack [21], [22]. There have been many studies about addition of fibers to the asphalt concrete like above, but most of them are focusing on thermoplastic material, few Abstract; Data Availability solutions are not yet widely used in modern pavement design or construction because of the lack of understanding of their long-term effects and field is anticipated to help overcome technical and nontechnical barriers and unlock the potential of biological additives for their use in concrete pavements.Use of Biological Additives in Concrete Pavements: A Review of

The effects of using reclaimed asphalt pavements (RAP) on the

In addition, new additives and recycling materials such as reclaimed asphalt pavement (RAP) have been extensively used in recent years and shown to have significant effect on the low-temperature cracking resistance of asphalt mixture. However, the effects have not been considered in the existing D(t) prediction models.Fig. 2 shows the fatigue test results, the S-N curves. It can be seen from Fig. 2 (b), showing a linear trend at the log-log scale, the mix of 2.5 % HL at the three temperatures has the smallest slope. Meanwhile, at the same initial strain, the 2.5 % HL mix has the highest load repetition number (N f) before failure at temperature 25 °C, and at Experimental study of temperature effect on the mechanical

Effect of air voids and asphalt content changes on laboratory and

Fatigue cracking is the most common, yet complicated type of flexible pavement distress. Volumetric properties of asphalt concrete (AC) mixtures are considered as key factors affecting their fatigue behavior. Most of available studies focus more on the sensitivity of laboratory fatigue behavior under different volumetric properties, while In their work, carbon fiber fabrics in the forms of filament, woven fabric, and unidirectional fabric were embedded into the concrete matrix to manufacture anti-icing pavements, and it was reported that these carbon fabric-pavements exhibited satisfied anti-icing performance, the generated electric-heat was sufficient to heat samples from Processes Free Full-Text Durability of Pavement Materials with

The results of the tests, carried out by the authors, showed that crystalline admixtures reduce the water vapor permeability of concrete by 16-20 %. The authors also carried out the water pressureThe use of recycled asphalt pavement (RAP) materials in asphalt concrete pavements (ACP) brings significant cost and environmental benefits. In practice, however, the amount of RAP readily available far exceeds the amount being utilized in ACPs, which still leaves the problem of excess RAP in the environment partially solved.
