“…Shirodkar et al (2013) investigated the addition of ash to a hot asphalt mixture as a mineral filler and/or as a crustaceous substrate in a small-scale mixture. The results showed that resistance to asbestos baking and asbestos, covering between 0% and 2% of the ash, has been comparable to conventional asphalt [31]. The Tenza-Abril research (2014) also analyzed the preservation of bituminous mixtures fed with ash taken from peasant settlements as a mineral filler.…”

“…Combustion ashes show pozzolanic activity after a longer period, which makes them eligible for active mineral additives. The maximum exchange of the binder-cement to ash-is 5-20% [11,21,24,31,60]. The use of SSA ashes with a high CaO content, while maintaining the appropriate W/C ratio (0.5), means obtaining mortars and concretes with mechanical properties similar to the reference samples [70].…”

Concrete is an ecological material with a high potential to adapt to specific operating conditions, and the lowest carbon footprint as it is made from local raw materials—aggregate, cement, water, admixtures, and mineral additives. It is the most widely used composite material among those that are man-made and second only to water in the entire range of materials used. The aim of this research was to assess the possibility of using fly ash from the thermal treatment of sewage sludge as an alternative additive to concretes resistant to environmental influences occurring in communication tunnels. A concrete mix based on CEM I 42.5R Portland cement with various ash content of 0–20% of the cement mass was designed for the experimental work. In the course of the experimental work, the compressive strength was measured after three maturing periods, and the influence of both high temperature and the material modification on the course of carbonation were determined. The test results confirm the possibility of producing plain concrete, modified with fly ash obtained from the thermal treatment of sewage sludge. The highest average compressive strength of 43.6 MPa, 45.6 MPa, and 51.2 MPa after 28, 56 and 720 days of maturation, respectively, was for concrete containing 10% ash.

“…Badania przeprowadzone przez Shirodkara i wsp. [5] potwierdziły korzystny wpływ popiołów ze spalania osadów ściekowych na poprawę odporności na pękanie oraz obciążenia pionowe asfaltu. Inne rezultaty badań wykazały, że mieszanka asfaltowa zawierająca w swoim składzie do 2% popiołu charakteryzuje się zbliżoną wytrzymałością do nawierzchni niemodyfikowanej [6].…”

The increasing consumerism and the improvement of lifestyle result in the production of various fractions of waste. Some waste indicates specific properties and for this reason, it application is advantageous in many sectors of economy. Regardless to the development of recycling technologies, most of generated waste is dumped. The landfilling of waste is wastage of valuable substances with a great management potential. This paper presents the possibility of recycling of waste in construction and road industry focus on the protection of environment and the reduction of reduction of consumption of raw materials.
