【摘要】 SMA路面由于采用的级配为断级配,集料间隙用沥青玛蹄脂填充,在使用改性沥青和木质纤维后,SMA混合料具有抗滑、表面排水、减少溅水、降低噪音等优点。但在施工中,只有严格控制各施工工序,才能充分发挥SMA路面的优势。更多还原

【Abstract】 Because the gradation of SMA is open and the aggregate clearance is filled with mastic asphalt,after the addition of modified asphalt and wood fiber,such advantages of SMA mixture as slip resistance,surface drainage,fewer splashes and reducing noise can be brought into full play.In the construction of SMA pavement,only when each working procedure is controlled strictly,can the advantages of SMA be brought into full play.更多还原
