The first use of concrete block paving for improving existing aircraft pavements was made at London Luton Airport UK in October 1981. Initial trials comprised two rectangular panels each 9 m x 2 m constructed on an apron stand directly beneath undercarriage gear positions. Rectangular block paving units 100 mm x 200 mm x 80 mm thick were used as an inlay to replace damaged bituminous overlay ma...

This paper deals with the fundamental differences between industrial and paving-grade bituminous binders. The is presented in two main sections: 1) a review of materials’ colloidal structure required properties for paving applications; 2) wide range experimental tests which binders were studied compared. In this research, 160/220 bitumen was compared to same penetration lower penetration, 70/10...

For several years, the bituminous laboratory of the Joint High­ way Research Project has been concerned with the testing of bitu­ minous-aggregate mixtures and with the development of knowledge that would lead to an understanding of the properties of bituminous mixtures as satisfactory paving materials. At the Thirty-Eighth Annual Road School, a paper entitled, “Role of the Laboratory in the De...

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...

In the present study, an attempt is made to find usage and utilization of by-products or recycledmaterials in bituminous paving mixes. The experiment started with conduction basic tests for various materials like Coarse aggregate, Fine Bitumen, by-product recycled copper slag, foundry sand, brickbats. These were tested their suitability carrying out work as a prediction know alternative these m...

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...

-In hot countries like India roads laid on agricultural zones and other water prone areas will be affected by severed pot holes created due to the water entry in the pavement. Increase in road traffic in combination with insufficient maintenance due to shortage in funds causes rapid deterioration of the roads. To lighten this process, several measures may be effective, such as, use of better qu...
