凯斯PT240型充气式压路机是美国Georgia州城镇公路建设的得力之选,它所压实的沥青路面可以保证良好的低空隙率。据了解,美国Georgia州交通运输局对于城市路面有严格要求,其中一项指标就是沥青路面的空隙率不得高于6%。若沥青路面中的空隙含量过高,则会造成路面裂纹和不平整的缺陷。因此施工方C&H Paving公司在公路建设中一直在努力保证低空隙率,经过定期测试表明,其可达到的空隙率为3%~4%,因此,由该公司铺设的路面也被评为Georgia州最优
The Case PT240 inflatable roller compactor is a viable option for urban road construction in Georgia, USA, where compacted asphalt pavements ensure good low void fraction. It is understood that the Georgia State Department of Transportation for the urban pavement has strict requirements, one of the indicators is the asphalt pavement porosity of not more than 6%. If the asphalt pavement in the void content is too high, it will cause road cracks and uneven defects. As a result, C & H Paving, a contractor, has been working hard to ensure a low void fraction in road construction. Regular tests show that the achievable void fraction is between 3% and 4%. Therefore, the pavement laid by the company is also rated as Georgia Optimal
