Abstract: The present invention relates to an ACME centralized management system and a load balancing method thereof. The system is connected with an ACME client and a plurality of certificate authorities (CAs) respectively and comprises an ACME unloading module, and a statistics module, a strategy module, a verification module and a notification module which are connected with the ACME unloading module respectively. The ACME unloading module is in communication with the ACME client and the plurality of certificate authorities (CAs). Compared with the prior art, the present invention has the advantages of avoiding frequent verification, quickly issuing certificate copies, more efficiently issuing certificates, etc.

Abstract: The present invention discloses a method of hot recycling repairing by optimizing a proportion of an asphalt mixture on a pavement alignment variation section. According to the method of the present invention, by regulating and optimizing the proportion of a recycled asphalt mixture, internal frictional resistance and cohesion of the recycled asphalt mixture are improved, elastic modulus and shear strength of the recycled asphalt mixture are increased, overall bearing capacity of an asphalt pavement is improved, and diseases such as tracks caused by vehicle loads are effectively resisted. The pavement asphalt mixture is made to adapt to and be enough to bear additional loads increased manifold without generating early defects and road diseases. Therefore, the overall service life of a road is further prolonged.
