The present invention relates to a hybrid road paving material and a road paving method, and more particularly, to a hybrid road paving material and a road paving method that can ensure high rigidity and high durability and can extend the pavement life.

In general, road pavement can be divided into concrete pavement and asphalt pavement, and the problems of such concrete pavement and asphalt pavement are as follows.

First of all, concrete pavement is a pavement with rigidity, which has a long construction and curing period, cracks due to dry shrinkage, and has relative disadvantages compared to asphalt pavement in terms of increased running noise, running property, and slip resistance.

In addition, in case of concrete pavement, road damage does not occur due to plastic deformation, but its function is less than that of asphalt road pavement in terms of walking and running stability and comfort, and the curing time of cement concrete is longer, so the installation time of pavement is longer. Because of its long length, it is not easy to apply other than the new section of the road.

Asphalt pavement is a flexible pavement with the advantages of a concept contrary to the disadvantages of concrete pavements listed above.

However, in the case of asphalt pavement, plastic deformation occurs due to the increase of annual average temperature and congestion due to long-term high temperature phenomenon in the summer and heavy vehicle and traffic increase, resulting in shorter pavement life and road maintenance cost. In addition, the heat island phenomenon occurs due to the rise of the temperature of the package due to the long-term high temperature in the summer, and the disadvantages such as increased discomfort due to the radiant heat during road driving and walking were also shown.

In order to remedy this problem, some improvement measures are currently in the development or implementation stage, but the fundamental measures have not yet been established.

Improvement measures in the current stage of implementation include the use of polymer modified asphalt pavement, which improves temperature and flow resistance by modifying the asphalt binder, and improves the particle size of the aggregate used and reinforces the fiber material. SMA (Stone Mastic Asphalt) pavement and semi-rigid pavement that combines the advantages of asphalt pavement and concrete pavement have been implemented.However, there are limitations to counter changes in the road environment, As a countermeasure, the development of this is urgently required.
