Firstly, this article touches abut the Superiority of the Soviet theory—considered about plenty influencing factors, invoving numerous observation and experimental data, experimental data being intellectually linkedua with the basic theory, setforthing from the viewpoint of equal-strength and borne with a sound and wholesome consideration about the roadway-pavement system. Then the writer talks about the probability to encounter with some contradictions in the basic theory and designing methods during the development, and he says it's qnite natural. Finelly, Some comparatively important problems of the developmant drection be discussed more in detail. Special stress be laid on the necessity to investigate more thoroughly the pavement stress and strength. The writer also gives his own idea on the designing schemes.

文章里谈到了苏联理论的优越性:所考虑的因素较多、观察与试验的数据较丰富;能把观察与试验的结果和理论联系起来、纳入整套理论之中;以及它是从等强度出发的,并对路基和路面作了综合的考虑。其次谈到,在使用理论和在深入研究时、对现行理论和方法必然会发现一些矛盾。这是事物发展的自然规律。在深入研究时要客观地分析;要重视试验结果,也要重视使用与观察所反映的情况。尤其要注意地区的特点。最后谈到了发展方向中几个比较重要的问题。较详细地谈到只用形变模量这个指标是不够的,说明了为什么必须分析路面应力和研究路面强度的构成与演变过程。也谈到有关设计方案方面的意见。

In this paper, the writer gives the results of a survey of concrete pavements built in various places in China. After a careful study of the results of this survey, he presents some proposals for the design and construction of concrete pavement, including its thickness, subbase, subgrade, joints, etc. Tests of concrete with admixtures of plasticizers and air-entraining agents were made in laboratory. From the results of the tests, the writer finds out that there are many advantages of the admixtures,...

In this paper, the writer gives the results of a survey of concrete pavements built in various places in China. After a careful study of the results of this survey, he presents some proposals for the design and construction of concrete pavement, including its thickness, subbase, subgrade, joints, etc. Tests of concrete with admixtures of plasticizers and air-entraining agents were made in laboratory. From the results of the tests, the writer finds out that there are many advantages of the admixtures, such as, reducing the contraction cracks during the curing period of concrete, and improving the durability and resistances to pacolation and freezing of concrete. In the last part of this paper, different formulae for design of the thickness of concrete pavement given by eight authors were reviewed. After a careful study and discussion of these formulae, the writer points out that in almost all these existing formulae, the consideration of the influences of traffic density and bearing capacity of subbase and subgrade to the performance of the concrete pavement is insufficient, therefor, he hopes to work out more refined and rational formula for the design of the thickness of conerete pavement.

本文收集国內各地部分水泥混凝土路面有关資料,加以分析与研究,对水泥混凝土路面的設計与施工,提出了若干建議性意見,其中包括面版厚度、底层与接縫等。对摻有塑化剂和加气剂的混凝土,进行了室內試驗研究,結果认为混凝土經加入这些外摻剂后,有很大优点,其中主要是:可以减除混凝土在养生期中的收縮裂縫,而且它的抗水、抗冻和耐久性等可以得到提高。最后,本文对八种水泥混凝土路面結构計算公式,进行了分析与研究,认为几乎所有这些公式都对行車密度和基础强度对于混凝土路面版工作的影响,考虑得不够。因此,作者认为有必要进一步研究出一种更合理更精确的公式,用以設計水泥混凝土路面的厚度。
