TL;DR: In this paper, ground penetrating radar (GPR) technology has been used to assess pavement performance and structure for the past 30 years in a variety of ways, and the main issue remains: How well does GPR work and under what conditions?

TL;DR: In this article, an in-depth review of the literature related to RAP was conducted to determine the appropriate level of contribution that should be given to the residual asphalt binder in RAP, and the level of interaction between aged and virgin binders was then used to investigate the influence on the performance and the durability of the mixtures as compared to virgin HMA.

TL;DR: In this paper, a fracture energy and flexibility index (FI) was proposed to screen asphalt concrete mixtures' cracking resistance using the semi-circular bending test geometry, and the results indicated positive correlation between SCB test results and other independent fatigue tests.

TL;DR: In this paper, a three-dimensional finite element (FE) model was developed to simulate pavement responses to vehicular loading at different temperatures and speeds, and compared with field-measured pavement responses from the Virginia Smart Road.

TL;DR: In this article, a hybrid LCA was used to analyze the environmental footprint of using a reclaimed asphalt pavement (RAP) content in asphalt binder mixtures, and the results showed significant reductions in energy consumption and greenhouse gas (GHG) emissions with an increase in RAP content.
