摘要
延长水泥混凝土路面使用寿命，在国民经济中占有相当重要的地位，是交通部亟待解决的课题０依据黑龙江省地理、气候的特点，为提高水泥混凝土路面耐久性，对水泥混凝土抗冻性、粗集料、路面基层等问题进行了研究。
It takes important position in natioal economic to prolong service life of cement concrete pavament, which is a problem to be solved in transportation branch. This research is carried to enhance durability or cement concrete pavement around several problems, such as frozen resistance, coarse aggregate, base course.
