一、我国筑路机械行业发展的基本状况 1.我国路面机械发展的几个基本阶段。路面机械在我国工程机械行业的发展中属于起步较晚、发展较慢的门类。虽然路面机械的研制和开发早在六十年代就已开始了,但是在六十年代初至七十年代末的近二十年间,发展速度十分缓慢。当时生产的主要是供修筑低等级公路(包括砂石路面)和养护用的小型机具,如沥青洒布车、小型沥青搅拌设备、在东方红54拖拉机上改装的路拌设备等。由于六十年代中期至七十年代中期文革的影响,我国路面机械发展处于仃滞状态。只是由于行业中的一些有责任心的科技人员的坚持努力,仍然研制开发了一些新产品,如铺宽4.5m的LT-6型沥
First, the basic situation of China’s road building machinery industry 1. Several basic stages of the development of road machinery in China. Pavement machinery in China’s construction machinery industry belongs to the late start, the development of slower categories. Although the development and development of pavement machinery started in the 1960s, the pace of development has been very slow during the nearly two decades from the early 1960s to the late 1970s. Production was mainly for the construction of low-grade roads (including gravel pavement) and maintenance of small equipment, such as asphalt sprinklers, small asphalt mixing equipment, the East Red 54 tractor modified road mixing equipment. Due to the influence of the Cultural Revolution from the mid-1960s to the mid-1970s, the development of road machinery in our country is in a sluggish state. Just because of the persistent efforts of some responsible scientific and technical personnel in the industry, we have still developed some new products, such as 4.5m wide LT-6
