本文以南非两个路面加速加载试验(APT)系统MLS和HVS模拟演示为基础，介绍了它们的现场应用技术参数和测试效果及车辆路面用的动态应力(STRESS-IN-MOTION系统)信息，为南非和中国两国的交通技术在此领域交流与合作提供了参考。
对于断板率较高的水泥混凝土路面，目前常采用冲压技术使原路面破裂稳固后加铺沥青结构层进行改造，但目前对路面板破裂尺寸大小国内外取值相差较大，且缺乏相应的理论依据。本文采用三维有限元法计算分析了水泥混凝土路面板破裂尺寸与沥青加铺层的荷载应力、温度应力、耦合应力及基层顶面压应力之间的关系。结果表明，路面板破裂尺寸对沥青加铺层的温度应力及耦合应力的影响远大于对荷载应力的影响，且随着破裂尺寸的减小，沥青加铺
