问:何谓沥青混凝土,其物理力学性能如何? 答:沥青混凝土是指用沥青作为胶粘剂,加入块石、砂等骨料,按一定级配比例加热拌制而成。沥青作为一种建筑材料,以其特殊的不透水性、可塑性和耐久性而著称,因此特别适用于水力发电和其它土木、水利等工程。其应用历史已很久远,但用作大面积防渗衬砌还是近二十年随着石油工业崛起而发展起来的。据不完全统计,我国已建成的各种沥青混凝土堤坝及其它工程近100项。最近正
Q: What is the physical and mechanical properties of asphalt concrete? A: Asphalt concrete refers to the use of asphalt as an adhesive, adding aggregates such as lumps and sand, and heating and mixing at a given grading ratio. As a building material, asphalt is known for its special water impermeability, plasticity and durability, so it is particularly suitable for hydropower and other civil engineering, water conservancy and other projects. Its application history has been a long time ago, but it has been used as a large-scale anti-seepage lining, which has developed in the past two decades with the rise of the oil industry. According to incomplete statistics, China has built nearly 100 asphalt concrete dams and other projects. Recently positive
