The design life of a newly built road is usually 15 years. According to surveys and relevant data, when the road is in normal driving conditions and is not overloaded, it usually enters the overhaul and intermediate maintenance periods in 5-7 years. The cycle of major repairs and intermediate repairs is generally about 3 years (such as highway milling and surfacing projects). After 3 years, diseases of varying degrees will appear, such as cracks, ruts, etc. According to our company's follow-up investigation of several roads that have adopted hot recycling technology in recent years. If the road undergoes hot in place recycling maintenance once every 3 to 4 years of use and controls overloading to a certain extent, it can ensure that the major and medium repair time of the road is postponed by 5 to 7 years, and the economic benefits are self-evident.
