Therefore, the Multi-functional Regeneration Concrete (MRC) invented by us is substituted for traditional Granular Subgrade Material. It can improve road’s Base and Sub-base Material and strengthen stability of road’s construction. MRC is a kind of concrete of the Cement, and if the compressive strength is 1.96-4.9MPa until 28th day, MRC can be decided range of compressive strength by your need. Nowadays, most of people in Taiwan improve road’s Base and Sub-base Material or use engineering of Edge Drain Trench. This research experiment about materials of MRC, and our experiment focus on material strength of MRC and temperature, so that we can utilize their relationship (strength, temperature and time of material of MRC), and we use formula and maturity concept to estimate the development of compressive strength of MRC. And then we can fine the best constructional time for AC after we use MRC. Moreover, we can control the time of being open to traffic and reduce the heavy traffic. Therefore, we can control the progress of engineering of MRC. In the future, MRC can be designed reference for correlated engineering in internal or foreign country.
