铜(铜川)柳(柳林沟)公路因为交通密度大,1963年决定加铺沥青双层表面处治,厚度为2.5厘米。结合料用太原钢厂副产品,软煤沥青和煤焦油。自7月中旬开始铺筑,至10月中旬停铺,共完成双层沥青表面处治9公里,质量良好。兹将施工方法及体会简述如下:一、加强旧路面整体强度与平整度的几种作法甲,原路面情况。去年施工的路段,除2公里系正式铺筑拳石路面外,其他均未铺筑正式路面,所有的路面系逐年养护加铺砂砾磨耗层形成的,路面宽约4.0～5.0米,平均厚度约9厘米,路拱横坡约4%～6%,表面坑槽甚多,土基强度据测定资料是旧路面下 E 0.015=260～800 0.020=230～660 公斤/平方厘米,原路肩(拟加宽路面部份)E0.015=140～800 0.020=130～680 公斤/平方厘米。从上述情况看,旧路面厚度不均,宽度不一,路拱较 Copper (Tongchuan) willow (Liulin ditch) highway because of traffic density, 1963 decided to add asphalt surface treatment, the thickness of 2.5 cm. Taiyuan Iron and Steel combined with the by-products, soft coal tar and coal tar. Paving began in mid-July and stopped in mid-October. A total of 9 kilometers of double-layer asphalt surface treatment was completed with good quality. The construction methods and experience will be briefly described as follows: First, to strengthen the overall strength of the old pavement and the flatness of several practices A, the original road conditions. Last year, the construction of the road section, in addition to 2 kilometers of formal paving fist stone pavement, the other are not paving the official pavement, all the pavement maintenance paved gravel abrasion layer formed each year, the road width of 4.0 to 5.0 meters, the average thickness of about 9 cm, road arch about 4% to 6%, many surface pit, soil strength according to the measured data is the old road E 0.015 = 260 ~ 800 0.020 = 230 ~ 660 kg / cm, the original shoulder Widening the pavement part) E0.015 = 140 ~ 800 0.020 = 130 ~ 680 kg / cm. From the above situation, the uneven thickness of the old pavement, the width of different road arch
