Application Analysis

In domestic asphalt pavement micro-surfacing technology is a new kind of pavement maintenance technology. Starting with the micro-surfacing technology application effect, we analyzed the micro-surfacing technology characteristics and application conditions. We also analyzed and discussed the application prospect, strive to provide a technical reference for promotion and application of micro surfacing technology.

Maintenance Techniques

With the aggravation of high grade highway asphalt pavement destructions, it becomes particularly important to maintain pavement performance and enhance road economic efficiency. The asphalt pavement preventive maintenance technology is an effective technique to extend pavement services and maintain pavement performance. In this paper, we combine the decay model of pavement performance with assets value evaluation idea and establish an analytical method about preventive maintenance technology based on assets evaluation. An example of hot asphalt overlay is also presented, it is found that preventive maintenance techniques can reduce the attenuation of road infrastructure assets value and maintain pavement performance efficiently.

New Type

In this paper, the abilities of recovery and regeneration for aged asphalt of a new type of asphalt pavement maintenance agent are studied. The agent is applied in the construction of test section of Yuhe Road, and the pavement performances before and after the construction are compared. The test indicates that after the maintenance agent is added into aged asphalt, the penetration and ductility are effectively improved, the softening point is lowered. When the penetration depth of agent reaches 6 mm，the texture depth , friction coefficient and antiskid value are improved to some extent ,the water permeability coefficient is reduced, and the appearance of pavement is improved as well，The paper provided reference for the applying curing agent of asphalt pavement to the preventive maintenance system.
