This study is about on the quality of bituminous coatings used for the rehabilitation of the Grand-Gassam-Nzikro road. Several tests in situ (temperature measurement and coring test) and laboratory tests (binder extraction, Marshall test and particle size analysis) were carried out in order to verify the conformity of the physical and mechanical characteristics of these mixes with those contained in the Notebook of Special Technical Clauses (CCTP). This study has shown that the application temperature of enrobes varies between 135.88° C and 146.2° C. The thicknesses of enrobe used are between 4.7 and 5.6 cm. He showed that the binder contents of different mixes are around 6%. The reliability of enrobe was confirmed thanks to the Marshall tests. Finally, this study has highlighted the two granular classes used for the manufacture of asphalt. The results obtained are satisfactory and conform to the specifications contained in the CCTP.
This work aims to recycle non-biodegradable waste, fight against environmental pollution and improve the performance of construction products. It is to develop a methodology and tools for making tiles made from glass bottle shards. To do this unused bottles have been collected and processed to granulates for making tiles cement-stabilized to the habitat coating. The results show that 0.40 is compared Cement / Tesson optimal to have shimmering tiles with a homogeneous distribution of shards in the cement matrix. The study of the water / cement ratio (W / C) indicates to a W / C ratio between 0.5 and 0.6 for good shaped by densifying the material and improved mechanical performance.
