The cement concrete pavements in cold regions often suffer from surface scaling or internal cracking under freeze - thaw cycles
寒冷地區的混凝土路面常因凍融循環而表面剝落、內部疏鬆開裂，影響結構的使用。 -
The experiment test results of mechanical properties and durability of hprrc show : no matter at early age or later age, the ration of flexural strength to the cubic compression strength of hprrc is higher than ordinary concrete, and the brittleness of hprrc is reduced ; the bond performance of new - old concrete interface and chloride permeability are good ; its resistance to freeze and thaw, permeability are all excellent ; its volume stability is improved, and its cracking resistance is good
配製出和易性優良（坍落度30mm ） 12 48h能滿足開放交通的hprrc 。 5 、 hprrc力學性能、耐久性能試驗結果表明：無論早期還是後期，其折壓比均比普通砼的有所提高，脆性有所降低；新老砼粘結性能優良；並具有優異的抗凍性、抗滲性、耐磨性，抗氯離子滲透能力強；體積穩定性大為提高，抗裂性好。
