Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

One important role in asphalt mixture performances is represented by the filler content and characteristics. This research aims to assess potential usage of industrial waste powders as replacers standard limestone composition. First all, an SEM EDX analysis was carried out figure whether this can be used composition comparing results wastes with properties filler. After a chemical evaluation, l...

Reclaimed asphalt pavement (RAP) is considered one of the valuable alternatives to raw materials due reducing need use materials, which are less in some world regions. It additionally reduces highly-priced new bitumen required inside asphaltic mixture manufacturing and contributes preservation natural resources. To achieve maximum benefit from integration RAP mixture, it necessary investigate a...

| A natural way to test the structural integrity of a pavement is to send signals with different frequencies through the pavement and compare the results with the signals passing through an ideal pavement. For this comparison, we must determine how, for the corresponding mixture, the elasticity E depends on the frequency f in the range from 0.1 to 10 5 Hz. It is very expensive to perform measur...
