在我国现有公路中铺有泥结碎石路面(亦即砂石路)的公路里程目前仍占多数,而且短期内不可能将现有的砂石路面全部改建为沥青路面,因此,如何科学地养护砂石路显得尤为重要。本人在养护工班工作多年,对养护砂石路面积累了一些经验,现总结几点,与同行们共同研讨。 Currently, the mileage of highway covered with clay-bonded gravel pavement (that is, gravel road) in the existing highway in our country still accounts for the majority, and it is impossible for the existing gravel road to be converted into asphalt pavement in the short term.
