目前全国各地的公路,多数还没有铺面层。不铺面层的问题在于多数地区,缺乏路面材料。如何解决缺乏砂石地区修筑路面的问题,现在正在研究和采用的办法,主要有:1.沥青砖路面,2.水泥稳定土壤路面,3.石灰稳定土壤路面,4.人造石(陶粒)路面,5。碎砖和砖块路面,6.矽酸盐制品(灰砌砖)路面,7.炉渣路面,8.贝壳路面等。但是这些办法,仍有缺乏材料的问题存在,如沥青究竟生产少,修高级路面还买不到,用以大量铺筑一般晴雨通车路面,自然不能办到;洋水泥供应紧张,修桥尚有困难,用以大修路面,供应必成问
At present, most of the roads in the country have not been paved. The problem with non-pavement lies in most areas, the lack of pavement materials. How to solve the lack of gravel road construction problems, now being studied and adopted, are: 1. asphalt brick pavement, 2. cement stabilized soil pavement, 3. lime stabilized soil pavement, 4. artificial stone (ceramsite) Pavement, 5. Broken brick and brick pavement, 6. silicate products (gray brick) pavement, 7. slag pavement, 8. Shell pavement and so on. However, there are still some problems with these materials, such as the fact that there is little production of asphalt and the cost of repairing high-grade pavements can not be met for laying a large number of ordinary rain-paved roads. Naturally, cement supply is limited and repair bridges still have Difficult to overhaul the road, the supply will be asked
