Bituminous materials are playing a vital role in pavement design and the roofing industry because of outstanding properties. Unfortunately, bituminous materials will release volatile organic compounds (VOC), making them non-environmentally friendly. Therefore, technologies that can be used to decrease the VOC emission are urgently required. In this research, the VOC emission and material behavi...

Poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. To improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. The main objective of this study is to explore the influence of...

Objective . The properties of road bitumen, when interacting with the components building compositions, are always transformed relative to their original properties. Therefore, working materials based on filled bitumen regardless field application, main task is monitor dynamics changes in characteristics and control required direction, as well maintaining such viscosity, flexibility fluidity. p...

Forms of selenium in bituminous coal, anthracite, and cokeite (natural coke) from Huaibei Coalfield, Anhui, China, have been determined by sequential solvent extraction. The selenium content in bulk samples is 4.0, 2.4, and 2.0 microg/g in bituminous coal, anthracite, and cokeite, respectively. The six forms of selenium determined by six-step solvent extraction are water-leachable, ion-exchange...

This paper presents results of investigation the possibility of replacing the mineral filler with fly ash from power plant “Gacko” in the bituminous aggregate mixture BNS 22A. The most important physical-mechanical properties of bituminous aggregate mixture with fly ash from power plant “Gacko” used as filler were investigated. Based on the results obtained it was concluded that fly ash from po...

Rutting is one of the most important distresses in asphalt pavements due to its frequency. Rutting or channeling, could be classified in three types: 1) mechanical deformation (rutting in subgrade or base), 2) plastic flow (unstable asphalt layer), and 3) wheel path consolidation. The plastic flow of bituminous mixture depends on many factors; one of this is the type of asphalt used in the mixt...

Bituminous mix design is a delicate balancing act between the proportions of aggregate sizes and bitumen content. For a given aggregate gradation, the optimum bitumen content is estimated by satisfying a number of mix design parameters recommended in the specifications. In this paper, some of new considerations related to the bituminous mix design are discussed. Bituminous mix design, with thes...
