“…The primary goal of bitumen stabilization in this research project was to increase mechanical strength. This binder filled the voids between the particles, resulting in a low permeability coefficient [29][30][31]. However, this slight loss in permeability due to binder filling the voids had little effect, resulting in a coefficient of permeability within the acceptable range.…”

Roads play a crucial role in fostering economic growth and providing social advantages in every nation. However, over time, road infrastructure can become outdated. According to studies conducted by World Highways, a road may seem to be in good condition on the surface while hiding a severe issue beneath. As a result, periodic maintenance, repairs, or modernization may be necessary for road structures. The primary purpose of this project was to investigate the effects of permeability on road base materials by removing particles and restoring strength through stabilization with bitumen. Optimum grade 60/70 bitumen was used in compliance with Malaysia JKR specifications to create a realistic case scenario. The formulation excluded open-graded road base material with particles smaller than 1.18 mm or 2.0 mm, and bitumen stabilization levels of 0%, 2%, 2.5%, and 3% were implemented to reduce the decrease in mechanical strength. The mechanical strength was determined using the California Bearing Ratio (CBR) test, while a Constant Head Method Permeability test was conducted to identify the optimal design mix with the maximum achievable permeability coefficient. The results showed that bitumen stabilization increased the mechanical strength of the road base material, with the highest result compensating for the drop by 8.7%. With open-graded road base material, the permeability can be increased by up to 17.2%. Therefore, open-graded road foundation material with bitumen as a binder for stabilization can be used in the construction of pavements in Malaysia, an area with relatively high rainfall intensity.

“…The Landscape and Aesthetics Design Manual states that the highway landscape aims to provide better definition of the elements of the facility and reduce the stress on users that results from operating a vehicle in a complex environment [29]. However, current highway landscaping design addresses vehicle noise in terms of noise walls that are built to reduce the noise impact on the neighborhoods.…”

“…Early research on the effect of pavement characteristics on noise has focused on using open-graded friction courses (with a higher ratio of air voids) that helps reduce noise because it is porous. This mix helps absorb road noise and helps water runoff [29]. Asphalt pavement can also be made even quieter by using eco-friendly recycled tires (rubberized asphalt).…”

Current highway landscape design guidelines focus only on the visual aspect of the landscape. This paper presents a comprehensive framework for highway landscape planning/design that considers all four senses (vision, sound, touch, and smell). The framework includes advanced technologies, such as electroencephalograms, electromyograms, galvanic skin response, and light detection and ranging that are used to evaluate the and physiological aspects of all users (drivers, pedestrians, and cyclists). In addition, two new elements are included in the framework: landscape consistency and the pavement as a landscape. The traditional landscape applications (structural features and transportation elements) and the emerging applications (tunnels, freeways, pedestrian paths, and cyclist paths) are described. Important landscape considerations, including sustainability, traffic safety, persons with disabilities, and education and research are discussed. The proposed framework, which reflects emerging developments in China, Europe, and other countries, should be of interest to highway practitioners involved in highway landscaping design.

“…Many researchers have demonstrated that permeable road pavements with high porosity offer numerous advantages. These include reducing flood runoff and improving hydrology [1,2], reducing noise [3][4][5], aiding the growth of ecological environment plants [6], and lowering surface temperatures and the urban heat island effect [7]. However, their open-graded design makes them susceptible to low structural strength and clogging issues [8][9][10], restricting their application to areas with light traffic volume and low bearing capacity [8,11,12].…”

Permeable road pavements, due to their open-graded design, suffer from low structural strength, restricting their use in areas with light traffic volume and low bearing capacity. To expand application of permeable road pavements, accurate simulation of stress parameters used in pavement design is essential. A 3D finite element (3D FE) model was developed using ABAQUS/CAE 2021 to simulate pavement stress responses. Utilizing a 53 cm thick permeable road pavement and a 315/80 R22.5 wheel as prototypes, the model was calibrated and validated, with its accuracy confirmed through t-test statistical analysis. Simulations of wheel speeds at 11, 15, and 22 m/s revealed significant impact on pavement depths of 3 cm and 8 cm, while minimal effects were observed at depths of 13 cm and 33 cm. Notably, stress values at a depth of 3 cm with 15 m/s speed in the open-graded asphalt concrete (OGFC) surface layer exceeded those at the speed of 11 m/s, while at a depth of 8 cm in the porous asphalt concrete (PAC) base layer, an opposite performance was observed. This may be attributed to the higher elastic modulus of the OGFC surface layer, which results in different response trends to velocity changes. Overall, lower speeds increase stress responses and prolong action times for both layers, negatively affecting pavement performance. Increasing the moduli of layers is recommended for new permeable road pavements for low-speed traffic. Furthermore, considering the effects of heavy loads and changes in wheel speed, the recommended design depth for permeable road pavement is 30 cm. These conclusions provide a reference for the design of permeable road pavements to address climate change and improve performance.
