Basic Steps and Economic Benefit Analysis of Thermal Regeneration

(1) Basic steps
The basic steps of thermal regeneration include: analysis of the damage status of historical information machines on old roads, evaluation of the carrying capacity of old road structures, traffic control evaluation, construction condition evaluation, and environmental evaluation. Based on the basic content of hot recycled asphalt mixture design, carry out hot recycled design and construction.
The design and construction of thermal regeneration include excavation and crushing of old roads, addition and batching of regeneration agents, mixing of thermal regeneration mixtures, paving and rolling, and acceptance.
(2) Economic Benefit Analysis
The investment cost of on-site thermal regeneration includes initial investment and survival costs, including on-site thermal regeneration construction equipment and regeneration machines, regeneration agents, fuel costs, etc; The benefits generated include saving on raw material costs, waste treatment related expenses, etc. Specific projects require specific evaluations.
Factory mixing heat recovery can be achieved by appropriately modifying existing hot mixed asphalt mixture machinery, without the need for specialized equipment procurement. It can achieve good economic benefits.
(3) Social and environmental benefits
The on-site thermal regeneration technology fully utilizes the old asphalt mixture, solves the problem of environmental pollution, and meets the requirements of waste resource utilization; Save a large amount of asphalt and stone, reduce the demand for materials, and alleviate the tense situation of supply and demand; Timely repair old asphalt pavement that cannot be updated, improve road conditions, increase transportation capacity, alleviate traffic tension, and reduce potential traffic accidents; Moreover, the health preservation period is short, the time to cut off traffic is greatly shortened, and social opinion and influence are reduced.
The on-site thermal regeneration technology has saved mineral resources, effectively slowed down ecological damage, avoided pollution of old asphalt pavement materials, and achieved significant social benefits; Moreover, with the continuous improvement of environmental protection requirements at home and abroad, asphalt pavement regeneration technology will have a broader market space.
