surfaces may have the same roughness index but one surface may have the roughness on average spaced farThe measurement of the roughness of soil surfaces on centimeter ther apart on the surface. A more complete characterizascales is important to modeling local soil erodibility. An acoustic backscatter technique was examined for its ability to quantify the tion would describe not only vertical sc...

evaluating existing flexible pavement condition is a pre-requisite to choose improvement technique that has to be adopted to enhance its quality. to evaluate existing pavements, non-destructive testing methods are desirable. benkelman beam and 5th wheel bump integrator are used to conduct non-destructive tests like deflection and roughness surveys on the existing pavement of 4 lane divided carr...

Deterioration models are important and essential part of any Pavement Management System (PMS). These models are used to predict future pavement situation based on existence condition, parameters causing deterioration and implications of various maintenance and rehabilitation policies on pavement. The majority of these models are based on roughness which is one of the most important indices in p...

The paper presents the color image segmentation based on rough-set approach has been proposed. The color image segmentation is one of the most challenging tasks particularly in the area of image analysis, computer vision, and pattern recognition. In this paper, the proposed algorithm based on roughness index to calculate the peaks and valleys values. Based on peak and valley values to achieve b...

Pembangunan infrastruktur jalan merupakan suatu kebutuhan mutlak bagi pengembangan wilayah agar tercapai kesinambungan dan pemerataan pembangunan pada setiap daerah serta membentuk struktur ruang dalam rangka mewujudkan sarana nasional. Untuk membuka isolasi akses masyarakat terhadap perkembangan perekonomian di Kota Wamena, pemerintah melaksanakan pemeliharaan jalan. Pemeliharaan bertujuan unt...

to properly plan for construction, repair, maintenance, and reconstruction of highways the minimum acceptable roadway condition is needed information. this, along with other pavement management tools, will help select the most desirable roadway alternatives. in this research the minimum acceptable conditions are developed based on an opinion survey of non-technical but high-level decision maker...
