Utilization of Drilling Cuttings in the Technological Process of Asphalt-concrete Mixture Production

It is established that the presence of oil and oil products in the amounts usual for drill cuttings is not a negative factor for asphalt concrete structural formation. Asphalt concrete specimens with different contents of drill cuttings were tested and it was found that the best results were shown by the specimen from which the bulk of clay particles was removed. It is concluded that the developed technological approach with the addition of drill cuttings to the composition of asphalt-concrete mixture allows to effectively use its mineral part as well as oil and oil products to form the structure of asphalt-concrete, which ensures the subsequent operation of the latter as the top layer of the road surface.
