摘要
详细论述了水泥混凝土路面早期病害的成因，提供了补偿收缩与层间减摩相结合的防止开裂的新方法，并提出了延长缩缝间距以减少病害的理论依据。铺筑了约1．3km试验路，获得了较好的路用效果。
This paper describes in detail the origin of early flaws about cement concrete. It also deliversa way of preventing cracking by uniting with compensating shrinkage and reducing interlayer frectional bond of concrete facelayer and base, and provides theory about elongation of the space ofcontraction joints to reduce early falws. Test pavements 1. 3 km with this way have been constructed showing good results.
