Preparation of double layered specimen at laboratory scale is important in evaluating the performance of bond strength between pavement layers since it is normally less costly. It however involved single face compaction at wearing course layer during the specimen preparation which raised potential skepticism over the quality of the layer compacted at single face only. This paper presents the properties of single face compacted porous asphalt (SFCPA) specimen compared to conventional double face compacted porous asphalt (DFCPA) specimen. These specimens were of Grading A in accordance with the specification from Malaysia Public Works Department (PWD). The permeability and abrasive loss were investigated for specimens fabricated at 3 thicknesses of 35mm, 50mm and 65mm at an allowable limit of ±1mm. 50 blows compaction at each face according to PWD specification is adopted for DFCPA specimen, which resulted in compacting effort of 100 blows compaction for SFCPA specimen was applied for every thickness. For both tests, SFCPA possessed lower permeability and abrasive losses compared to DFCPA. This observation is the consequences of potential aggregate crushing in SFCPA which then partly filled up the voids within the specimen and reducing the permeability. Increased in density as a result of permeability reduction had increased the interlocking between coated aggregate particles, hence the abrasive loss in SFCPA is lessened.

Runoff Control

We examined the possibility of improved runoff control in a porous asphalt pavement by installing beneath it an infiltration pipe with a numerical simulation model that can simulate rainfall infiltration and runoff at the porous asphalt pavement. From the results of simulations about runoff and infiltration at the porous asphalt pavement, it became clear that putting a pipe under the porous asphalt pavement had considerable effect, especially during the latter part of the rainfall.

Porous asphalt (PA) mixtures are more environmentally friendly but have lower durability than dense-graded mixtures. Additives can be incorporated into PA mixtures to enhance their mechanical strength; however, they may compromise the hydraulic characteristics, increase the total cost of pavement, and negatively affect the environment. In this paper, PA mixtures were produced with 5 different types of additives including 4 fibers and 1 filler. Their performances were compared with the reference mixtures containing virgin bitumen and polymer-modified bitumen. The performance of all mixes was assessed using: mechanical, hydraulic, economic, and environmental indicators. Then, the Delphi method was applied to compute the relative weights for the parameters in multi-criteria decision-making methods. Evaluation based on distance from average solution (EDAS), technique for order of the preference by similarity to ideal solution (TOPSIS), and weighted aggregated sum product assessment (WASPAS) were employed to rank the additives. According to the results obtained, aramid pulp displayed comparable and, for some parameters such as abrasion resistance, even better performance than polymer-modified bitumen, whereas cellulose fiber demonstrated the best performance regarding sustainability, due to economic and environmental benefits.
