【摘要】：沥青混合料是高速公路、城市道路的主要铺面材料，它直接承受车轮荷载和各种自然因素（如日照、温度、空气和雨水等）的作用影响，其性能和状态都会发生变化，以至于影响路面的使用性能和使用寿命。为了保证沥青路面长期保持良好的使用状态，沥青混合料必须满足高温稳定性、低温抗裂性能和抗水损害性能。钢渣废胶粉沥青混凝土室内研究属于空白，工程应用未见报道，需全面评价钢渣废胶粉沥青混凝土混合料路用性能，进行钢渣废胶粉沥青混凝土混合料高温稳定性、低温抗裂性能、水稳定性能、疲劳性能等方面的评价，并与普通沥青混合料和SBS改性沥青混合料进行对比。本文根据实际工程，在施工与设计良好情况下，钢渣废胶粉改性沥青混凝土路面比普通沥青混凝土路面使用寿命长，寿命长表示养护的费用少，减少养护和维修引起的道路断交，，减少车户时间延误，减少施工所引起道路周边环保问题。钢渣废胶粉沥青路面在低温条件下仍然有一定弹性，车辆行驶路面时车轮可以破坏路面上冰层，而起到防止路面结冰，加大路面与轮胎间的滑动阻。所以钢渣废胶粉改性沥青路面起到碎冰、防滑作用，提高了司乘人员的安全，增加路上的服务质量。还增加了雨天抗滑，减少了溅水，雨天行车视线更清晰，且与路上标线形成强烈对比，夜间的可视性有了明显增强，夜间道路用户的路上安全性有明显增加。间接节约了道路用户费用。
[Abstract]:Asphalt mixture is the main highway, city road pavement material, which is directly under the wheel load and all kinds of natural factors (such as temperature, sunshine, air and water etc.) the effect of the performance and the state will change, so that the influence of the pavement performance and service life of asphalt pavement. In order to ensure good use state for a long time, the asphalt mixture must meet high temperature stability, low temperature crack resistance and water resistance.
Steel slag asphalt concrete of crumb rubber interior is blank, the engineering application has not been reported, comprehensive evaluation of steel slag crumb rubber asphalt concrete mixture performance of steel slag, waste rubber asphalt concrete mixture high temperature stability, low temperature crack resistance, water stability, fatigue performance evaluation and other aspects, and with ordinary asphalt mixture and SBS comparison of asphalt mixture.
According to the actual engineering design and construction, in good condition, the steel slag crumb rubber modified asphalt concrete pavement than ordinary asphalt concrete pavement with long service life, long life said the maintenance cost, reduce maintenance and repair the road off, reduce the time Kurumado delay, reduce the environmental problems caused by the construction of surrounding roads.
Steel slag waste rubber asphalt pavement under low temperature condition still has certain elasticity, the vehicle road wheel can damage the road on the ice, but to prevent the ice on the road, increasing the sliding resistance between pavement and tyre. So the steel slag crumb rubber modified asphalt pavement to crushed ice, anti-skid effect, improve the safety of the driver on the way, increase the quality of service. Also increased the wet skid resistance, reduce splash, rainy day sight clearer, and contrast with road markings, visibility at night has been enhanced and the night road users of Lu Shangan has increased significantly. The indirect saving road user costs.
