In summary, based on local raw materials, research and development works on modified cero-asphalt concrete resistant to hot climate conditions were analyzed. The shortcomings of the asphalt concrete pavement in hot climates and its current status were studied. The reasons for the deterioration of asphalt concrete pavements in hot climates and the formation of transverse cracks have also been scientifically analyzed (Khursandov B. Sh. 2022). From the obtained calculations, it can be said that the roads covered with ceroaphalt concrete are more effective from the economic point of view. When the economic efficiency was calculated, it was found that the roads with asphalt concrete pavement offered by us are much cheaper and of better quality than roads with asphalt concrete pavement. Construction of 1 km asphalt concrete road 1 km asphalt concrete road will be built for 256 million 902 thousand soums cheaper. It is very economically efficient.
