保龙高速公路SMA沥青路面施工质量控制

The Construction Quality Control of the SMA Asphalt Pavement in Bao Long Highway

SMA路面同以往的密级配沥青混凝土路面相比,在抗车辙、防水损害、耐久性、抗滑等指标方面均有显著提高,因而被广泛用作沥青路面罩面。但实际施工过程中存在一些问题,影响了SMA的路用性能。本文针对SMA沥青路面施工过程中存在的不足,结合云南省实际工程,提出相应对策、采取相关措施,以提高施工质量。

Compared to former asphalt - concrete pavement, SMA pavement has significant improvement on anti-rut, water damage prevention, durability and anti-skidding, so it is widely used as the cover of asphalt pavement. However, there＇s some problem during actual construction, which affects the performance of SMA. The paper focuses on disadvantages of SMA during implementation, developing appli-cable treatments in accordance with practical works, and will adopt some measures to improve the construction quality.
