As it is shown in quality changes chart during time, preventing maintenance is the lowest cost type of road maintenance. We execute different types of preventing maintenance as Micro-Surfacing, Chip-Sealing, Scrub-Sealing. Also in defer action stage we need to create a tension absorbing layer with an anti reflection cracking system which leads us to use Cape-Seal

Our company constructs over 400 kilometers of rural asphalt roads in deprived areas in Iran every year. These projects connect nearly 100 small villages to each other and main roads. The projects are mostly scattered over a vast area of 250 thousand square kilometers, which is nearly as much as the land area in Oman. Therefore, it is not economically feasible to install fixed asphalt plants for each individual project, so we have redeveloped a method for making cold asphalt using a special bitumen emulsion and then designed some mobile asphalt plants for producing and implementing that kind of asphalt.
