TL;DR: A review of the repeatability and harmonization of field-testing methods for macrotexture is outlined in this article, and the gap between lab test and field test for skid resistance should be bridged to realize more accurate estimation of pavement frictional properties in the phase of lab design.

TL;DR: In this paper, the influence of chemical composition of aggregate on emulsified asphalt demulsification speed was examined, and the results indicated that mixing ratio of chemical components has a significant effect on asphalt emulsion.

TL;DR: In this article, the authors evaluated the use of different asphalt pavements, varying in resilience, to optimize braking performance on pavement and found that with improvements in pavement elasticity, the actual tire-pavement contact area increased, which gives us the ability to effectively strengthen the frictional adhesion of the tire to the pavement.

TL;DR: Experimental results indicate that the specific surface energy parameter of the aggregate is certainly related to the particle size of the aggregation, and Orthogonal experimental analysis demonstrates that the surface energy and specific surface area have an impact on the emulsion breaking speed and they are proven to be positively correlated.

TL;DR: In this article, the adsorption of five anionic emulsifiers on the SiO2 surface was compared with that on the CaCO3 surface, and the results showed that the adsoration of the hydrophilic group of an ionic emulsifier on SiO 2 surface was stronger than that on Ca CO3 surface.
