Properties Of High Performance Pavement Concrete Mix Design And Road

The research of High Performance Pavement Concrete (HPPC)is done in two sides. One is mixture design, the other is pavement performance.The mixture design and design flowchart of HPPC is given on the base of NC with the consideration of characteristic of both HPPC and NC.The grow law,influencing factor and formation mechanism of HPPC strength is analisised by perpendicular experiment.In the same,the fatigue equations are set up for HPPC and HPPC I on the base of fatigue experiment.The fatigue mechanism of HPPC is analysised by damage mechanics and fracture mechanics.Brittleness,frost resistance and abrasion resistance of HPPC is researched with the camparition to NC I .At last,the economic analysis of HPPC is done by two kinds of way.
