“…Due to its porosity and aggregate gradation, this asphalt concrete has a negative texture, and it can mitigate noise with sound pressure level differentials of approximately 3.5 dB(A) at standard speeds. The usual levels can range from 74 to 76 dB(A) [50]. As for friction, the initially measured values can range from 50 to 70 BPN [51].…”

As cities grow in size, traffic also increases, thus making the population more exposed to road noise and traffic accidents. It is therefore important to study and understand which properties of the pavement influence its acoustic impact and skid resistance performance. The pavement texture plays a major role in generating noise and friction, and it can be engineered in order to control both of them at the same time. The phenomena regulating skid resistance are well understood today. The same applies for noise generation and propagation; the literature contains methods of designing the pavement surface layer to achieve consistent results. Several types of solutions can be found for asphalt mixtures, most of them derived from decades of studies and research. They use different approaches to be effective for noise and friction, but all have in common the control of the surface’s macro and microtexture. Finally, some considerations are made regarding novel paving solutions with artificial aggregates instead of natural ones to address noise and skid resistance.

“…Ravelling is considered the most common distress observed in PA mixtures (Alvarez et al 2011, Putman and Kline 2012, Wu et al 2020. This phenomenon can be described as the loss of aggregate due to the abrasive load generated by the passage of vehicles.…”

“…Despite the modification of all the PA mixtures designs, the range of values for functional responses varied from 18.69% to 23.22% for T AV and from 12.39% to 14.46% for I AV . Although in the majority of countries in Europe the minimum recommended porosity is 20%, in other countries such as the USA the recommended porosity is no less than 18% (Wu et al 2020). Therefore, it could be said that all mixture designs could perform well despite the reductions in voids.…”

Porous asphalt (PA) mixture is setting off an attractive alternative to be used as surface layer in pavements due to the many profits this mixture provides in terms of noise, safety and environmental aspects. Nonetheless, its use is quite limited due to its low durability in comparison to dense graded asphalt mixtures, reason for which the incorporation of different additives is recommended. In this study, the impact of different types of binders and additives in porous asphalt mixtures are experimentally assessed. A total of 54 experimental designs were defined through the Taguchi design of experiments method. Total air voids, interconnected air voids, particle loss in dry and wet conditions and binder drain down were the responses obtained from the experimental tests. Since more than one response was obtained, three Multi-Criteria Decision-Making (MCDM) methods were performed to turn the multiple response optimisation problem into single-objective optimisation problem. Based on the experimental results and statistical analysis, polymer modified binders improve the ravelling resistance without affecting the functional performance of the mixture and without presenting the risk of binder drain down.

“…Eco‐porous concrete (EPC) is a kind of green concrete, which is mainly formed with open‐graded coarse aggregate, water, cement and other admixtures, and its special frame structure can provide the growth path for the roots of vegetation. Compared with ordinary concrete, eco‐porous concrete (EPC) has the function of planting, water purification, noise reduction and reducing heat island effect, which plays an important role in improving ecological environment . Up till now, eco‐porous concrete (EPC) has been used in parking lots, roadside slope, shoulder partitions and other projects in Japan, the United States and other countries.…”

To investigate the structural compatibility of eco‐porous concrete (EPC) and vegetation, a simulation method (sand penetration coefficient) of structure compatibility between the eco‐porous concrete (EPC) and vegetation was put forward. Furthermore, the relation between sand penetration coefficient and pore characteristics were analyzed, and the technology of acquiring equivalent pore size was optimized. The results present that the new simulation method, characterized by sand penetration coefficient, can effectively assess the ability of eco‐porous concrete (EPC) to allow the root system to pass through. In addition, the real pore structure shape by “rubbing technology” can be easily and quickly obtained.
