Research conclusions: The gradation of graded broken stone must satisfy the technical requirements． The stone should be washed and the fine particles below 0.075 mm should be screened out during construction．The quality control index should include the unconfined compressive strength in different age and different dosage，the freeze thawing，the permeability，the resilience modulus，the shrinkage and the fatigue，and all these indexs should increase before and after the construction．The plain concrete can be made of the graded broken stone with cement，and this construction method is mature． The plain concrete strength should be designed as C25 to keep enough stiffness and prevent freezing damage．But the concrete grade should not be too high and its volume should not be too big in order to avoid the high cost of the high grade and mass concrete with being easy to crack．
