There is no substitute for sustainable and environment friendly roads for globalization and urban development. The prevention of asphalt pavement distresses, various researchers have numerous findings. Kenaf Fiber is mainly use to increase the tensile strength of pavement composite. The fiber asphalt mixture has better resistance cracking degradation under loading. According the definition of the Federal Highway Administration (FHWA), sustainable development should meet three requirements: meeting performance standards, utilizing resource effectively and preserving the ecosystem. Kenaf fiber is ecofriendly and sustainable material

The modification of fiber-containing porous asphalt with various additives : A review

The use of porous asphalt pavement has increased in recent years compared to conventional asphalt pavement. In this regard, pedestrian walkways and parking lots often make use of porous asphalt. These kinds of additives should be used in porous asphalt pavement because they enhance the pavements serviceability and mechanical performance. These types of pavement are used in various types of fiber and additives to improve the porous asphalt pavements physical characteristics and decrease the air void in the asphalt mixture. Incorporating different types of fibers with various types of additives should increase the overall performance of porous asphalt pavement though fiber has a significant impact over the additives on pavement structure. However, some additives increase the mechanical properties of porous asphalt. Pavement design mechanism and size of aggregate is a valuable component of serviceability of porous asphalt pavement. Consider all this factor it is easily determines the strength and durability of porous asphalt pavement in the context of physical and mechanical performences. This review focus on the overall performances of porous asphalt incorporating fiber with various types of additive

Microstructure analysis of porous asphalt incorporating kenaf fiber in the pavement

Hot mix asphalt (HMA) is the most of the popular pavement in Malaysia and most economical materials available. Besides that, this pavement type also very suitable with this country climate but HMA need frequency rehabilitation and maintenance due the damages caused by traffic load. In ways to minimize the damage and increase the services life of pavement, modification of asphalt binder is one of the approaches to improve pavement performance and services life. HMA can be modified with many types of fibre including natural fibre. This study utilises the usage of natural fibre as modifier of porous asphalt. The performance of modified porous asphalt is assessed by microstructure analysis. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), Fourier Transform Infrared Spectrophotometer (FTIR), Powder X-ray Diffractometer (XRD), and Permanence Deformation Resistance are some of the laboratory results that have been used. The characteristics of PA modification with 0.3% kenaf fibre are demonstrated in this research. In the interior structure of PA, kenaf fiber diffuses effectively. C and Ca elements contributed the most in the experiment, as did the element and chemical content of PA modified with kenaf fiber. In comparison to the control specimen, changed PA has more persistent deformation and PA with 0.6% kenaf fiber had the greatest resilient modulus value. From the results, it displays that the addition of natural fibre is able to enhance the performance of porous asphalt. This study also promotes the sustainable building materials especially in pavement construction

Evaluation of Flexible Pavement Distresses due to Undesirable Commercial Vehicles Activity

A study was carried out to evaluate the flexible pavement distresses for cracking and potholes in the parking area with and without commercial activity. Infrastructures such as parking areas are commonly used for another activity rather than for car park only. For example, fresh market, ceremony, and concert. This Study focusing on open space parking area as the gaps between other researchers that studied on highways or road network. The chosen of site location were divide into two categories which are urban area, Kuantan city and the educational area, Universiti Malaysia Pahang, Gambang. The aim is to study the severity level of distresses appeared on parking area. Therefore, the main objective is determining the most severe area of distresses by visual observation and performing the image software analysis to analyze the severity level of distresses with the guideline in collecting data based on national guidelines, published by the Public Works Department. Besides, performing Image Interpretation Group (IIG) as the method to classified the severity level by using Gwyddion Software. The data shows, 5 sample distresses for potholes were founded and 7 sample for cracking was collected at each site area. For the conclusion, parking area with commercial activity at urban area recorded the high number distresses and classified as the worst condition among the other site of parking area
