Abstract: Asphalt concrete (AC) consists of coarse aggregate, asphalt binder, and fines. The asphalt binder creates an asphalt film around the coarse aggregate and fines. Fines are trapped inside the binder film, which is also known ...

Abstract: In a nanoindentation test, a test sample is indented or loaded by an intender tip and then unloaded, and the load-displacement data are recorded. Load-displacement data are then analyzed using a common method to determine ...

Abstract: Limiting the presence of water inside an asphalt concrete (AC) pavement can slow down the process involved in water diffusion, hydration, adhesion loss, and other mechanisms of moisture damage. In the past, numerous studies ...

Abstract: In this study, combinations of layer, stiffness, and thickness that produce an optimal perpetual pavement are determined for implementation on New Mexico State highways. Using a number of trial designs in the Mechanistic-Empirical ...

Abstract: Moisture damage in asphalt is one of the prime concerns for flexible pavements degradation worldwide. Many of the pavement distresses are the direct and indirect outcomes of the moisture intrusion in asphalt pavement. This ...

Abstract: Recently, dynamic modulus (

Abstract: Currently, the fatigue performance of asphalt concrete (AC) is predicted according to repeated traffic-induced tensile strain at the bottom of AC layer. Cyclic thermal strain caused by day-night temperature fluctuation is ...

Abstract: Polymers are commonly used to modify asphalt binder in order to satisfy the performance-grade binder’s rheological properties, such as shear, storage, loss, and bending stiffness. However, it is not known what types and ...

Abstract: In this study, a four-layer feed-forward neural network is constructed and applied to determine a mapping associating mix design and testing factors of asphalt concrete samples with their performance in conductance to flow ...

Abstract: The moisture damage in polymer modified asphalts has been studied for decades, yet the effects of chemical functional groups on moisture sensitivity are not known. In this study, a nanoscale experiment is conducted to ...
