| 摘要: |
| 将废玻璃用于沥青混合料来铺筑沥青路面,有助于废物利用和环境保护,并对沥青层的表面特征产生一定影响.废玻璃在沥青路面中应用的关键是改善玻璃与沥青的粘附性,试验结果表明,采用高粘度的改性沥青或以水泥作为抗剥落剂可以有效地提高玻璃与沥青的粘附性.掺加一定比例的废玻璃对沥青混合料的设计沥青用量影响不大,但会降低沥青混合料的密度,并使沥青混合料试件的马歇尔稳定度、抗车辙能力和抗滑性略有降低;随着废玻璃用量的增加,沥青层表面的反光性增加. |

| Abstract: |
| Crushed and screened waste glass could be used as a portion of aggregate in asphalt paving mixes,the term "glassphalt" has been used to describe the pavement.The practice has not only contributed to make use of waste materials and protect environment,but also to improve surface behavior of asphalt pavement.The key to use glassphalt lies in the fact that potential stripping problem can be reduced by improving adhesion between glass and asphalt,so that laboratory tests are designed to evaluate properties of adhesion and resistance to moisture stripping,and Marshall stability and resistance to rutting and skidding of mixes with glass.Based on the test results,effective means to reduce moisture stripping and to improve adhesion are recommend where high viscosity modified asphalt as binder or addition of cement as an antistripping agent would be used.The test results also show that apparent density,Marshall stability,resistance to rutting and skidding of samples containing waste glass are slightly lower than those without waste glass.The higher the content of waste glass is,the stronger the light reflection is. |
